With 0% VAT, Accelerated Capital Allowance, and the Clean Export Guarantee, commercial solar is one of the best investments an Irish business can make.
| System Size | Typical Cost | Annual Savings | Payback | 25-Year Return |

| 20 kWp (Small office) | €18,000–€24,000 | €5,000–€7,000 | 3–4 years | €125,000+ |
| 50 kWp (Medium business) | €40,000–€55,000 | €12,000–€18,000 | 3–4 years | €300,000+ |
| 100 kWp (Large facility) | €75,000–€100,000 | €25,000–€35,000 | 3–4 years | €625,000+ |
| 250 kWp+ (Warehouse/Industrial) | €175,000–€250,000 | €60,000–€80,000 | 3–4 years | €1,500,000+ |
Estimates based on current commercial electricity rates (€0.28–€0.35/kWh), 0% VAT, and 950–1,100 kWh/m² annual irradiance. Actual figures depend on roof orientation, shading, and consumption patterns.
Tax Benefits That Make Solar a No-Brainer
Accelerated Capital Allowance (ACA)
Write off 100% of your solar investment against corporation tax in Year 1. A €100K system saves your business €12,500 in tax immediately (at 12.5% rate).
SEAI NDMG Grant
The Non-Domestic Microgen Grant covers up to €162,600 for systems up to 1,000 kWp. Rates: €900/kWp (first 2kWp), €300/kWp (2–20kWp), €200/kWp (20–200kWp), €150/kWp (200–1,000kWp). Stackable with ACA.
Clean Export Guarantee
Sell surplus electricity back to the grid at guaranteed rates. Weekends, bank holidays, and quiet periods become revenue generators instead of wasted energy.
TAMS III (Farms)
Agricultural businesses can access TAMS III Solar Capital Investment Scheme covers 60% of costs up to €90,000 investment ceiling. Dramatically reduces payback to under 2 years.
Commercial Solar FAQ
Do I need planning permission?
Commercial rooftop installations up to 300 m² are generally exempt from planning permission, provided they are primarily for self-consumption. Ground-mounted systems over 75 m² require planning. Properties in Solar Safeguarding Zones (near airports) have additional restrictions. Your installer will confirm your specific situation.
Will it disrupt my business operations?
Minimal disruption. Most commercial installations are done on rooftops with no impact on daily operations. Typical install time is 1–3 weeks depending on system size.
What about roof structural integrity?
Your installer will conduct a structural survey before installation. Modern solar panels weigh approximately 12–15 kg/m², well within the load tolerance of most commercial roofs.
Can I finance the installation?
Yes. Options include business loans, green finance, leasing, and Power Purchase Agreements (PPAs) where you pay nothing upfront and buy the electricity at a discounted rate.
How does the ACA tax write-off work?
Under the Accelerated Capital Allowance scheme, you can deduct 100% of qualifying solar equipment costs from your taxable profits in Year 1. This means a €100K system reduces your tax bill by €12,500 (at 12.5% corporation tax) immediately, rather than depreciating over 8 years.
What maintenance is required?
Commercial solar requires minimal maintenance. An annual inspection and cleaning (€200–€500 depending on system size) keeps everything running optimally. Most panels come with 25-year performance warranties.
