Customer Reviews
// FAQ
GB NRG’s customers are typically seeing a 3–5-year return on investment for a new commercial solar system.
This is primarily driven by lower installation costs and higher electricity prices.
GB NRG’s customers typically offset 25–40% of their annual electricity demand with solar.
Businesses with strong daytime consumption – such as manufacturing and production – often achieve the highest savings.
GB NRG designs systems to maximise your on-site usage rather than exporting energy at lower rates.
System costs depend on size, site conditions, etc but as a guide system costs typically start from £100,000.
GB NRG offers multiple funding routes, including:
- Outright purchase for maximum ROI
- Asset finance / hire purchase
- Power Purchase Agreements (PPAs) i.e. no cost option
Many of our customers choose funding that delivers immediate cash-positive savings.
Our commercial systems typically add ~12 kg per square metre, considerably less weight than back in 2010 and rarely an issue with modern roof structures.
GB NRG carries out a full structural assessment ahead of installing any modules to ensure your building is suitable to take the extra weight.
Most rooftop commercial solar installations are classed as permitted development, meaning planning permission is usually not required.
However, additional consents often apply for:
- Listed buildings
- Conservation areas
- Ground-mounted systems
All projects require DNO grid approval, which GB NRG manages end-to-end as part of our service.
Solar PV is one of the most reliable energy technologies available, with no moving parts.
GB NRG systems require minimal maintenance, typically:
- Performance monitoring
- Annual inspections
- Annual panel cleaning
Battery storage can deliver real value – but only when it’s the right fit.
At GB NRG, we recommend batteries where businesses:
- Generate surplus solar energy
- Operate outside daylight hours
- Want to reduce peak-time costs
Many clients install solar first and add batteries later, once usage data confirms the business case.
