Jonathon Porritt told delegates at the Large Scale Solar UK conference in Kelham Hall, Nottinghamshire that the rumoured review of support for large-scale solar was politically motivated.
Sputnik Engineering, manufacturer of SolarMax inverters, has announced that more than 65MW of its inverters were successfully installed in the first quarter of 2014.
Any changes to support for large-scale solar farms would not come into force until the 2015/2016 financial year, according to an email circulated by DECC.
A proposed review of the level of support for large-scale solar is purely political and has no economic basis, according to the head of a major UK project developer.
