Sussex Solar is a Horsham-based installer of solar PV, battery storage, air source heat pumps and solar thermal hot water systems for homes and businesses. The company describes itself as family-owned and says it has operated since 2005 across Sussex, Surrey, Kent and Hampshire and has installed over 700 renewable energy systems. It is MCS certified for solar PV, battery storage, air source heat pumps and solar thermal (MCS certificate NIC-5025, checked on the MCS installer search on 25 September 2026).

The company says it assesses each property and sizes the system to its energy needs, and that all installations are carried out by its own directly employed team, never subcontracted. It also offers five-yearly maintenance and safety inspections of solar PV systems. For battery storage it installs Tesla Powerwall batteries, including the Powerwall 3, and GivEnergy batteries.

Its installation gallery shows solar PV on homes in Horsham, Broadbridge Heath, Southwater and East Grinstead, including a slate roof and a flat roof.
