What you get
Built around when your business uses power
Sized to daytime use
Businesses use most power in daylight, so more of each unit is used on site rather than sent to the grid.
G99/NI handled
We apply to NIE Networks before we install. Fast Track now allows up to 60 A per phase installed.S34

Worked examples
What a system could cost and save
Two example systems, worked out from published figures. They are examples, not customers. Your free survey gives your own figures.
Worked example
Business A: 68 panels (29.92 kW) on a small commercial unit
A site using at least 50,000 kWh a year, mostly on weekdays.
System
68 × 440 W panels, 29.92 kW, three-phase
Cost
£36,024, or £28,819 after grant
Makes
24,378 kWh a year
First-year saving
£3,531 to £5,296
Payback
5.4 to 8.2 years with grant
Payback counts savings on your bill only, not export payments. We confirm at your survey whether export payments apply to yours.
How we worked this out
- Cost: 29.92 kW × £1,204 per kW, the 2025-26 median for 10 to 50 kWS42S43, excluding VAT
- NISEP grant: 20% (£7,205), cap £30,000S56S57. No order can be placed before the grant offer.
- Output: 29.92 kW × 823 kWh per kW a year, the measured average for all NI solar in 2025S40, less 1% first-year wearS60 = 24,378 kWh
- Used on site: shown as 60% to 90% (14,627 to 21,940 kWh). Saves £3,531 to £5,296 at 24.14p, the UK business averageS51. Small businesses often pay moreS52, which shortens payback.
- Exported: 9,751 to 2,438 kWh. Not counted: export payments are left out of these figures.
- Without the grant: 6.8 to 10.2 years. Capital allowancesS31 are not included.
Worked example
Business B: 227 panels (99.88 kW) on a larger site
A site using at least 200,000 kWh a year.
System
227 × 440 W panels, 99.88 kW, three-phase
Cost
£120,256, or £96,205 after grant
Makes
81,379 kWh a year
First-year saving
£11,787 to £17,680
Payback
5.4 to 8.2 years with grant
No export payments counted: Power NI’s export price covers systems up to 50 kW.
How we worked this out
- Cost: 99.88 kW × £1,204 per kW, the 2025-26 median for 10 to 50 kWS42S43, excluding VAT. No published figure above 50 kW and cost per kW falls with size, so this is likely high. Grid connection costs not included.
- NISEP grant: 20% (£24,051), cap £30,000S56S57. No order can be placed before the grant offer.
- Output: 99.88 kW × 823 kWh per kW a year, the measured average for all NI solar in 2025S40, less 1% first-year wearS60 = 81,379 kWh
- Used on site: shown as 60% to 90% (48,827 to 73,241 kWh). Saves £11,787 to £17,680 at 24.14p, the UK business averageS51. Small businesses often pay moreS52, which shortens payback.
- Export valued at £0: the Power NI export price covers systems up to 50 kWS50.
- Without the grant: 6.8 to 10.2 years. Capital allowancesS31 are not included.

Questions from businesses
Business solar questions
My business runs on three-phase. Can you help?
Yes. Business and farm systems are usually three-phase and much larger than a home system. We design to your daytime load and handle the G99/NI approval with NIE Networks before we install.S21 See business solar.
What are G98 and G99?
They’re NIE Networks’ rules for connecting generation. A single-phase system with an inverter up to 3.68 kW is “fit and inform” under G98/NI, so we notify NIE Networks after installation. Larger systems, three-phase systems and most with a battery need G99/NI approval before we install. We handle both.S21
Will it work in a power cut?
It can. EcoFlow PowerOcean Plus can keep chosen loads on your business running in a power cut, with conditions we check at survey. Eleven Energy, coming soon once it is certified in Northern Ireland, will back up chosen essential circuits.S4S12 Tell us what matters to you at survey and we’ll design for it.
