How Many Solar Panels Are Needed to Power a House in Ireland? (2026 Guide)

The average Irish home needs 8 to 12 solar panels — a 3.2 to 4.8 kWp system — to cover 50-80% of its annual electricity usage. A typical 3-bed semi-detached house with an electricity bill of €150-€200 per month needs around 10 panels (4kWp), costing approximately €4,100 after the SEAI grant.

But that headline number only tells part of the story. The exact number of solar panels your home needs depends on how much electricity you use, the size and orientation of your roof, the efficiency of the panels you choose, and whether you plan to add a battery or charge an electric vehicle. In this guide, we walk through every variable so you can calculate the right system size for your home — down to the panel.

Ireland's solar industry has matured significantly heading into 2026. Panel efficiency has improved, installation costs have stabilised, and the SEAI grant still covers up to €2,400 of the upfront cost. With electricity prices remaining high and the Clean Export Guarantee allowing you to sell surplus power back to the grid, there has never been a better time to get the numbers right and invest in solar for your home.

How Many Solar Panels Do You Need? The Quick Answer

If you just want a fast answer, this table gives you the number of solar panels typically needed based on the size of your home in Ireland:

House Size	Number of Panels	System Size (kWp)	Approx. Annual Output
2-bed apartment/terrace	6 – 8	2.4 – 3.2 kWp	2,200 – 2,900 kWh
3-bed semi-detached	8 – 12	3.2 – 4.8 kWp	2,900 – 4,300 kWh
4-bed detached	12 – 16	4.8 – 6.4 kWp	4,300 – 5,800 kWh
5-bed detached	16 – 20	6.4 – 8.0 kWp	5,800 – 7,200 kWh

These figures assume standard 400W monocrystalline panels (the most commonly installed type in Ireland in 2026) and a south-facing or near-south-facing roof. If your roof faces east or west, you may need 10-15% more panels to achieve the same output. If you have shading from trees or neighbouring buildings, you may need additional panels to compensate.

How to Calculate the Right Number of Panels for Your Home

Rather than guessing, you can calculate the number of solar panels your home needs in four straightforward steps. This method works for any house in Ireland, regardless of size or location.

Step 1: Check Your Electricity Bill

Find your most recent electricity bill or log into your supplier's online portal. You are looking for your annual electricity consumption in kilowatt-hours (kWh). Most Irish electricity bills show this figure, or you can find it on your annual statement.

If you can only find your bimonthly usage, multiply by six. If you only have a monthly figure, multiply by twelve. The average Irish household uses approximately 4,200 kWh per year according to the Commission for Regulation of Utilities (CRU), though homes with electric heating, heat pumps, or electric vehicles may use significantly more.

Step 2: Decide How Much You Want Solar to Cover

Most homeowners aim to cover 50-80% of their annual electricity usage with solar panels. Covering 100% is technically possible but usually not cost-effective because solar generation is seasonal — you produce far more electricity in summer than in winter, and you would need an oversized system that exports a lot of surplus in summer just to cover the dark winter months.

A realistic target for most homes is 60-70%. This gives you strong savings while keeping the system size and cost reasonable. If you are adding a battery, you can push self-consumption towards the higher end of this range.

Step 3: Divide by Panel Output

In Ireland, a single 400W solar panel produces approximately 340-380 kWh per year on a well-oriented roof. The exact figure depends on your location (the southeast gets more sunshine than the northwest), roof pitch, and shading. A reasonable average for calculation purposes is 360 kWh per panel per year.

Here is the formula:

Number of panels = (Annual kWh usage x target coverage %) / 360

For example, a home using 4,200 kWh per year targeting 70% coverage:

(4,200 x 0.70) / 360 = 8.2 panels

So you would need approximately 8-9 panels, which translates to a 3.2-3.6 kWp system.

Step 4: Adjust for Your Roof

Now adjust the number based on your specific roof conditions:

• South-facing roof (160-200 degrees): No adjustment needed — this is the ideal orientation and what the calculation above assumes.
• Southeast or southwest facing: Add 5% more panels (about 1 extra for every 20).
• East or west facing: Add 10-15% more panels. A split east/west installation can actually be beneficial for spreading generation across the day.
• Partial shading: Add 10-20% more panels depending on severity. Modern panels with optimisers handle shading much better than older systems.
• Low roof pitch (under 20 degrees) or flat roof: Add 5-10% as the angle is not optimal for Ireland's latitude.

If your roof space is limited, you can use higher-efficiency panels to get more power from fewer panels, though these come at a slightly higher cost per panel.

Solar Panels Needed by House Type in Ireland

Different house types in Ireland have different electricity demands and different amounts of available roof space. Below is a detailed breakdown to help you find where your home fits:

House Type	Typical Monthly Bill	Annual Usage (kWh)	Recommended System	Number of Panels	Cost After SEAI Grant
1-2 bed apartment	€80 – €120	2,000 – 3,000	2.0 – 2.4 kWp	5 – 6	€2,600 – €3,200
2-bed terrace	€100 – €140	2,500 – 3,500	2.4 – 3.2 kWp	6 – 8	€3,000 – €3,800
3-bed semi-detached	€140 – €200	3,500 – 5,000	3.2 – 4.8 kWp	8 – 12	€3,600 – €5,200
3-bed detached	€160 – €220	4,000 – 5,500	4.0 – 5.2 kWp	10 – 13	€4,200 – €5,800
4-bed detached	€180 – €260	4,500 – 6,500	4.8 – 6.4 kWp	12 – 16	€5,000 – €7,200
5-bed detached	€220 – €320	5,500 – 8,000	6.4 – 8.0 kWp	16 – 20	€6,800 – €9,000
Large detached / farmhouse	€300+	7,500 – 12,000+	8.0 – 11.0 kWp	20 – 28	€8,500 – €12,000+

Important notes on the table above:

• Costs are based on mid-2026 Irish market prices including VAT (currently zero-rated for residential solar) and after the SEAI grant of up to €2,400.
• The "recommended system" assumes 60-70% coverage of annual electricity usage, which is the sweet spot for most Irish homes.
• Actual costs vary by installer, panel brand, and whether you add extras like a battery storage system or an EV charger.
• If your home has a heat pump, your electricity usage will be higher than the averages shown — factor in an additional 3,000-5,000 kWh per year for the heat pump and size your solar system accordingly.

Solar Panels Needed by Electricity Bill

Many homeowners find it easier to work from their electricity bill rather than house type. If you know roughly what you pay per month, this table tells you how many panels you are likely to need:

Monthly Electricity Bill	Estimated Annual Usage	Panels Needed (60-70% coverage)	System Size	Estimated Annual Savings
€100/month	2,800 – 3,200 kWh	6 – 7	2.4 – 2.8 kWp	€550 – €700
€150/month	4,000 – 4,500 kWh	8 – 10	3.2 – 4.0 kWp	€800 – €1,050
€200/month	5,200 – 6,000 kWh	10 – 13	4.0 – 5.2 kWp	€1,050 – €1,350
€250/month	6,500 – 7,500 kWh	12 – 16	4.8 – 6.4 kWp	€1,300 – €1,650
€300+/month	8,000 – 10,000+ kWh	16 – 22	6.4 – 8.8 kWp	€1,600 – €2,200+

These savings estimates include both direct self-consumption savings (electricity you generate and use yourself, avoiding buying it from the grid) and income from the Clean Export Guarantee (CEG), where your supplier pays you for surplus electricity exported to the grid. In 2026, CEG rates typically range from 18-24 cent per kWh depending on your supplier.

The savings assume current Irish electricity unit rates of approximately 35-42 cent per kWh including standing charges, PSO levy, and VAT. If electricity prices rise further — as many analysts expect — your actual savings will be higher than shown.

Keep in mind that these are estimates. Your actual savings depend on how well your electricity usage patterns align with solar generation. Households where someone is home during the day (working from home, retirees, families with young children) tend to achieve higher self-consumption rates and therefore higher savings.

What Size Solar Panel System Do You Need?

Solar panel systems in Ireland are measured in kilowatts peak (kWp), which refers to the maximum power output of the system under ideal conditions. Here is what each common system size covers and who it suits:

2 kW System (5 Panels)

A 2 kW system is the smallest commonly installed residential system. It generates approximately 1,800-2,000 kWh per year and suits apartments or very small homes with low electricity usage. At current prices, a 2 kW system costs around €3,800-€4,200 before the SEAI grant, falling to approximately €2,200-€2,600 after the grant.

This system is best for single occupants or couples in a small home who use under 3,000 kWh per year. It will cover roughly 60-70% of a low-usage household's electricity needs.

3 kW System (7-8 Panels)

A 3 kW system generates around 2,700-3,000 kWh per year and is a popular choice for 2-3 bed homes. It costs approximately €4,800-€5,400 before the grant, or €2,800-€3,400 after the SEAI grant of up to €1,800 (the grant scales with system size).

This is the "starter" system that many homeowners choose when they want to dip their toes into solar without a large upfront investment. It covers 50-65% of a typical 3-bed home's usage and offers a payback period of 5-6 years.

4 kW System (10 Panels)

The 4 kW system is the most popular residential system size in Ireland. It generates approximately 3,600-4,000 kWh per year and hits the sweet spot between cost, output, and return on investment. After the maximum SEAI grant of €2,400, a 4 kW system typically costs €3,600-€4,500.

A 4 kW system suits most 3-4 bed homes in Ireland. It covers 60-75% of average household electricity usage and offers a payback period of 4-6 years depending on your self-consumption rate. This is the system size we most frequently recommend for Irish homeowners.

5 kW System (12-13 Panels)

A 5 kW system produces 4,500-5,000 kWh per year and suits larger homes or households with above-average electricity usage. It costs approximately €5,800-€6,800 after the SEAI grant. This system size is increasingly popular among homeowners with heat pumps or those planning to install an EV charger.

At 5 kW, you start to generate meaningful surplus electricity during summer months, which you can either store in a battery, export to the grid via the CEG, or divert to heat your hot water using an immersion diverter.

6 kW System (15 Panels)

A 6 kW system generates 5,400-6,000 kWh per year and is designed for large detached homes, homes with heat pumps and EV chargers, or households with high electricity consumption. After the grant, expect to pay €6,800-€8,200.

This system requires more roof space — typically 25-30 square metres — so it is best suited to detached homes with a large, unobstructed south-facing roof. Homes that combine a 6 kW solar system with a battery storage system can achieve self-consumption rates of 70-85%, dramatically reducing their dependence on grid electricity.

For systems larger than 6 kW, you are moving into premium territory. These are typically installed on larger properties — farmhouses, period homes with high ceilings and poor insulation, or homes running multiple high-demand appliances. An SEAI-approved installer can advise on whether a system above 6 kW makes financial sense for your situation. Get a free quote here.

Factors That Affect How Many Panels You Need

The tables and calculations above give you a solid starting point, but several real-world factors can push your panel count up or down. Understanding these will help you fine-tune your system size.

Roof Orientation and Tilt

The direction your roof faces is the single biggest factor affecting solar panel output in Ireland. A south-facing roof at a pitch of 30-35 degrees is ideal and will achieve close to 100% of the panel's rated output. Here is how other orientations compare:

• Due south (180 degrees): 100% of optimal output
• South-southeast or south-southwest: 95-97% of optimal output
• Southeast or southwest: 87-93% of optimal output
• East or west: 78-85% of optimal output
• North-facing: Not recommended — only 55-65% of optimal output

If your roof faces east or west, you need roughly 15-20% more panels to match the output of a south-facing system. However, an east-west split installation has the advantage of spreading generation more evenly across the day, which can actually improve self-consumption if you use electricity in the morning and evening rather than at midday.

Shading

Even partial shading on a single panel can significantly reduce the output of an entire string of panels. Common sources of shading in Ireland include mature trees, chimneys, dormer windows, neighbouring buildings, and satellite dishes.

Modern solutions mitigate shading issues effectively. Panel-level optimisers (such as SolarEdge) or microinverters (such as Enphase) allow each panel to operate independently, so a shaded panel does not drag down the rest of the system. If your roof has shading, expect to need 10-20% more panels to compensate for reduced output, and budget for optimisers or microinverters.

Panel Efficiency and Wattage

Not all solar panels are created equal. The type and quality of panel you choose directly affects how many you need. In 2026, residential solar panels in Ireland typically range from 380W to 440W per panel:

• Standard panels (380-400W): The most commonly installed. Good efficiency, competitive pricing.
• Premium panels (410-440W): Higher efficiency means fewer panels needed for the same output, but at a higher cost per panel. Brands like SunPower, REC, and LG (where available) fall into this category.
• Budget panels (350-380W): Lower cost per panel but you need more of them, which means more roof space.

If roof space is tight, investing in premium high-efficiency panels can allow you to fit a larger system into a smaller area. If you have plenty of roof space, standard panels offer better value per watt.

Self-Consumption vs. Export

How you use the electricity your panels generate affects the financial return, which in turn influences the optimal system size. Electricity you use directly from your panels saves you 35-42 cent per kWh (the full retail rate you would otherwise pay your supplier). Electricity you export to the grid earns you only 18-24 cent per kWh under the Clean Export Guarantee.

This means a smaller system with high self-consumption can deliver better returns than a larger system where most of the energy is exported. The ideal balance depends on your household's daytime electricity usage. Homes where someone is home during the day — working remotely, minding children, or retired — naturally achieve higher self-consumption.

Battery Storage

Adding a battery storage system allows you to store surplus solar electricity generated during the day and use it in the evening when the sun goes down. A battery typically increases self-consumption from 30-40% (without battery) to 60-80% (with battery).

If you are installing a battery, it often makes sense to install a slightly larger solar system to keep the battery charged. For example, a home that would normally need 10 panels might install 12-14 panels when pairing with a 5 kWh battery, ensuring there is enough surplus generation to fill the battery on most days.

Battery costs in Ireland in 2026 range from approximately €2,500 for a 5 kWh unit to €6,000+ for a 10 kWh unit. The SEAI does not currently offer a separate battery grant, but the overall system grant applies.

EV Charging

If you drive an electric vehicle or are planning to buy one, your electricity consumption will increase by approximately 2,500-4,000 kWh per year depending on your annual mileage. This is equivalent to the output of an additional 7-11 solar panels.

Many Irish homeowners are now sizing their solar systems to account for EV charging. A typical approach is to add 2-4 extra panels beyond what your household usage requires. Combined with smart charging (setting your EV to charge during peak solar hours), you can power a significant portion of your driving from sunshine.

For example, a 3-bed semi with a €150/month electricity bill and an EV doing 15,000 km per year might need 12-14 panels instead of the 8-10 they would need without the car. The extra panels pay for themselves quickly given that solar electricity costs roughly 5-7 cent per kWh compared to 35-42 cent from the grid.

Can Solar Panels Power Your Entire House?

This is one of the most common questions we hear from Irish homeowners, and the honest answer is: solar panels can cover a substantial portion of your electricity needs, but powering 100% of your home year-round from solar alone is neither practical nor cost-effective in Ireland.

Here is why. Ireland's solar resource is highly seasonal. In June, a south-facing 4 kW system can generate 18-22 kWh per day — more than enough for most homes. But in December, that same system produces just 2-4 kWh per day, a fraction of what you need during the darkest, coldest months when heating, lighting, and cooking demand is highest.

Over the full year, a well-sized solar system typically covers:

• 50-60% of annual usage without a battery
• 65-80% of annual usage with a battery
• 80-90%+ of usage from March to September
• 15-30% of usage from November to January

To cover 100% of your annual usage on paper, you would need to massively oversize your system — perhaps 20-25 panels for a home that only needs 10. The excess summer generation would be exported to the grid at a lower rate (18-24c/kWh) than what you pay for imported electricity in winter (35-42c/kWh). The economics simply do not stack up.

The smarter approach is to size your system to cover 60-75% of your annual usage, add a battery to capture surplus daytime generation, and accept that you will still draw from the grid during winter evenings. This strategy maximises your return on investment and typically delivers a payback period of 4-6 years.

That said, if you combine solar panels with other energy-efficiency measures — proper insulation, a heat pump, LED lighting, smart heating controls — you can dramatically reduce your total electricity consumption, which in turn means solar covers a much larger percentage of a smaller bill. Many homeowners who undertake a deep retrofit find that their solar panels come close to covering their entire reduced electricity demand.

What If You Don't Have Enough Roof Space?

Not every home has a large, unobstructed south-facing roof. If your available roof space is limited, there are several strategies to maximise the solar capacity you can install:

Choose Higher-Efficiency Panels

Premium panels rated at 420-440W produce the same energy as standard 380W panels but take up the same physical space (approximately 1.7-1.8 m² per panel). By choosing higher-efficiency panels, you can fit 10-15% more generating capacity on the same roof area. The extra cost per panel is typically €30-60, which is often worthwhile when space is the limiting factor.

Use Both Roof Faces (Split Orientation)

If your roof runs east-west, you can install panels on both the east-facing and west-facing sides. While each side produces less than a south-facing installation, the combined output is typically 85-90% of what you would get from an equivalent south-facing system. An east-west split also spreads generation more evenly throughout the day, which can improve self-consumption.

For homes with a hip roof (four sides instead of two), panels can be installed on multiple faces to maximise the total capacity. Your installer will model the output from each face and recommend the optimal configuration.

Ground-Mounted Systems

If you have a large garden or open land, a ground-mounted solar array is an alternative to roof panels. Ground-mounted systems can be oriented and tilted at the optimal angle regardless of your roof, potentially producing 5-10% more energy than a roof system. They are also easier to clean and maintain.

Ground-mounted systems cost slightly more per kW due to the mounting structure and groundwork required (typically €500-€1,000 more than an equivalent roof system). They may also require planning permission if they exceed certain size thresholds — check the latest planning exemptions for details.

Reduce Your System Size and Maximise Self-Consumption

If you simply cannot fit as many panels as you would ideally like, focus on maximising the value of the panels you do install. A smaller system with high self-consumption (using most of the electricity you generate) delivers better returns per panel than a larger system where a lot of energy is exported.

Strategies to boost self-consumption include:

• Running the dishwasher, washing machine, and tumble dryer during peak solar hours (10am-3pm)
• Installing a solar diverter to heat your hot water tank with surplus solar electricity
• Adding a battery to capture surplus generation for evening use
• Setting EV charging schedules to align with solar production
• Using smart plugs and timers to shift loads to daytime

How Many Panels Fit on Your Roof?

Before finalising your system size, you need to confirm that your roof can physically accommodate the panels. Each standard 400W panel measures approximately 1.7m x 1.1m (1.87 m²), though sizes vary slightly between manufacturers.

Here is a quick sizing rule:

• Usable roof area ÷ 1.9 m² = maximum number of panels

The 1.9 m² figure accounts for the panel itself plus spacing for mounting rails and ventilation. You also need to leave a clear margin of at least 30cm from roof edges, ridges, and hips for safety and wind loading requirements.

Common roof sizes in Irish homes:

House Type	Typical Usable South-Facing Roof	Max Panels
Mid-terrace	12 – 18 m²	6 – 9
End-terrace / semi-detached	18 – 28 m²	9 – 14
Detached (standard)	25 – 40 m²	13 – 21
Large detached / dormer	35 – 55 m²	18 – 28
Bungalow	30 – 50 m²	15 – 26

These are estimates — dormers, skylights, chimneys, vents, and satellite dishes all reduce usable space. For a precise assessment of your roof, read our detailed roof space guide or request a free site assessment from an SEAI-approved installer who will use satellite imagery and measurement tools to determine exactly how many panels your roof can accommodate.

Frequently Asked Questions

How many solar panels do I need for a 3-bed house in Ireland?

A typical 3-bed semi-detached house in Ireland uses 3,500-5,000 kWh of electricity per year. To cover 60-70% of this usage, you need 8-12 solar panels (a 3.2-4.8 kWp system). The most common installation for a 3-bed home is 10 panels (4 kWp), which costs approximately €3,600-€4,500 after the SEAI grant and saves €800-€1,100 per year on electricity bills.

How many solar panels do I need for a 4-bed house in Ireland?

A 4-bed detached house typically uses 4,500-6,500 kWh per year. You would need 12-16 solar panels (4.8-6.4 kWp) to cover 60-70% of your usage. A common installation is 14 panels (5.6 kWp), costing €5,000-€6,500 after the grant with annual savings of €1,100-€1,500.

How many solar panels do I need for 5,000 kWh?

If your household uses 5,000 kWh per year and you want to cover 65-70% with solar, you need approximately 10-11 panels. The calculation: (5,000 x 0.675) / 360 = 9.4 panels, rounded up to 10. A 4 kW system of 10 panels would generate roughly 3,600 kWh per year, covering 72% of your 5,000 kWh usage.

How many solar panels do I need for 10,000 kWh?

Homes using 10,000 kWh per year (common for large homes with heat pumps or electric heating) need 18-20 panels (7.2-8.0 kWp) to cover approximately 65% of usage. This is a large system requiring around 38 m² of usable roof space. With a battery, self-consumption can reach 70-80%, saving €2,000-€2,500 per year.

How many solar panels do I need to charge an electric car?

The average Irish EV owner drives approximately 15,000 km per year, consuming around 2,500-3,000 kWh of electricity. To generate this from solar, you need 7-9 additional panels (2.8-3.6 kWp) beyond what your household requires. In practice, most EV owners add 3-5 extra panels to their household system and charge during peak solar hours, covering 50-70% of their driving from solar energy.

How many extra solar panels do I need if I have a heat pump?

A typical air-to-water heat pump in a well-insulated Irish home uses 3,000-5,000 kWh per year. To offset a significant portion of this, you would need 5-8 additional panels (2.0-3.2 kWp). However, heat pumps work hardest in winter when solar output is lowest, so the seasonal mismatch means solar realistically covers 30-50% of heat pump electricity annually. A larger system with battery storage improves this figure.

How much do solar panels cost in Ireland in 2026?

In 2026, a typical residential solar panel system in Ireland costs €5,500-€9,500 before the SEAI grant, depending on system size. After the grant (up to €2,400), costs range from approximately €3,100 for a small 2 kW system to €8,500+ for a large 8 kW system. For a detailed breakdown, see our complete guide to solar panel costs in Ireland.

Do solar panels actually work well in Ireland?

Yes. Despite Ireland's reputation for cloudy weather, solar panels work effectively here. Ireland receives 900-1,100 kWh of solar irradiance per square metre per year — enough for solar panels to be a sound financial investment. Modern panels perform well in diffuse light (cloudy conditions), and Ireland's cool temperatures actually improve panel efficiency compared to hotter countries where panels can overheat. Read our detailed analysis of how solar panels perform in Irish weather.

What is the SEAI grant for solar panels in 2026?

The SEAI solar PV grant for homeowners covers up to €2,400 of the installation cost. The grant is structured as €800 per kWp for the first 2 kWp and €250 per kWp for the next 2 kWp (up to 4 kWp). Your home must have been built and occupied before 2021 to qualify, and the installation must be completed by an SEAI-registered installer. The grant is applied directly by the installer, so you pay only the net cost.

How long do solar panels take to pay for themselves in Ireland?

The typical payback period for solar panels in Ireland in 2026 is 4-7 years, depending on system size, electricity usage, self-consumption rate, and whether you have a battery. A well-sized system for a home with good daytime usage can pay back in as little as 4 years. After payback, you enjoy 20+ years of near-free electricity, as panels are warrantied for 25-30 years. See our detailed payback analysis.

Do I need planning permission for solar panels in Ireland?

Most residential solar panel installations in Ireland are exempt from planning permission under updated regulations. You can install solar panels on your roof without planning permission provided the panels do not extend more than 15cm above the roof surface and do not project above the ridge line. Ground-mounted arrays up to 25 m² are also generally exempt. For full details, see our guide to planning permission exemptions for solar panels.

Can I sell excess solar electricity back to the grid in Ireland?

Yes. Under the Clean Export Guarantee (CEG), which has been in place since 2022, all Irish electricity suppliers must offer a payment for surplus solar electricity you export to the grid. In 2026, CEG rates range from approximately 18-24 cent per kWh depending on your supplier. While this is less than the retail rate you pay for imported electricity (35-42c/kWh), it provides a meaningful income stream — a typical 4 kW system exports 1,000-1,500 kWh per year, earning €180-€360 annually. Learn more in our guide to selling electricity back to the grid.

What are the best solar panels for Ireland in 2026?

The most popular and highly rated solar panels for Irish homes in 2026 include models from SunPower, REC, Canadian Solar, JA Solar, Trina Solar, and Longi. For most homeowners, a mid-range monocrystalline panel rated at 400-420W offers the best balance of efficiency, reliability, and value. Premium all-black panels from SunPower or REC offer superior efficiency and aesthetics but at a higher price point. See our guide to the best solar panel types for Ireland for a full comparison.

Do solar panels increase the value of your house in Ireland?

Yes. Research and estate agent reports consistently show that solar panels add value to Irish homes, typically increasing the property value by €5,000-€15,000 depending on the system size and the home's BER rating improvement. Solar panels improve your BER (Building Energy Rating), which is increasingly important to buyers. A home with a B2 or B3 BER rating (achievable with solar panels and basic insulation) sells faster and for a premium compared to similar homes rated C or D.
