Who Are Project Solar UK?
Founded in 2011, Project Solar UK is a nationwide solar panel and battery storage provider focused on simplifying the switch to solar. Headquartered in the North West and Midlands, the company operates more than 20 offices across the UK and offers residential and commercial installations – including solar panels, roof-integrated solar tiles, battery systems, EV chargers, and smart energy management.

Which Solar Panels Does Project Solar Install?
🏆 Evolution Evo Max Super
- Efficiency: 22.18%
- Wattage: 480W
- Warranty: Lifetime
- Type: Monocrystalline, TOPCon tech
The Evo Max Super is Project Solar’s flagship panel – designed for UK rooftops and low-light conditions. With high power density and impressive performance in fog, cloud, or partial shade, these panels are ideal for British homes where sunlight can be unreliable.
Thanks to TOPCon and passivated contact cell technology, they deliver better heat tolerance and long-term energy yield. Build-wise, they’re rated for 5400Pa snow loads and 2400Pa wind resistance – more than enough to survive UK winters.
Solar Battery Options
Project Solar supplies battery storage through its sister company, Project CURV, with two sizes available:
| Battery Size | Ideal For | Warranty | Features |
| 6kWh | 1-3 bed homes | 10 years | Remote monitoring, modular |
| 12kWh | 3-5 bed homes | 10 years | Off-peak & solar charging |
Both battery systems are expandable, app-controlled, and designed to store excess solar or cheaper off-peak grid electricity – helping reduce your reliance on peak rates or blackouts.
Solar Roof Tiles
For homes where appearance matters, Project Solar offers solar roof tiles as a low-profile alternative to raised panel systems.

While more expensive and slightly less efficient, they’re ideal for:
- Listed buildings
- Conservation areas
- Homeowners undergoing roof replacements
Tiles come with a 25-year performance and 12-year product warranty. Integration into existing roofs can be tricky, so they’re better suited to new builds or full roof refits.
EV Chargers
Through its brand Project EV, the company also supplies a range of home and commercial EV chargers from 7.3kW to 300kW – compatible with solar systems for maximum savings.
Features include:
- Smart scheduling via app
- Off-peak priority mode
- Solar-first charging
- 5-year warranty
Dynamic load balancing ensures your home’s energy is evenly distributed, avoiding tripped circuits.
