Our History


In 2006, with the UK's photovoltaic capacity at 12MW, Rajiv Bhatia founded Alternergy. Rapidly growing our loyal customer base and market share, national recognition followed for Alternergy as 'A Company to inspire Britain'.
We were on to something, and fully committed to deliver quality, value, integrity, and fun.


Alternergy has come a long way: more than 30 brands in our portfolio, Huawei FusionSolar Gold Partner,  a market-leading e-Commerce platform, and 'the best Account Managers in the market' according to our customers. Through 'solarcoaster' turbulences and rapid growth, we worked hard to continuously improve our highly personalised service.


Though one of the longest-serving solar PV distributors in the UK, we thrive on innovation. Energised by major system upgrades, service optimisation and continuing improvements on ACE PV, we are ready to charge ahead.
Join us in this exciting new era and see how Alternergy can power your future. Are you ready?
