Court cases and the lobbying of MPs are the two latest tactics employed as part of efforts to persuade the government to revise its decision to reduce Feed-in Tariff payments.
Approximately 200 people attended a demonstration and lobbying event at Westminster last week to speak to their MPs on the subject.
Among those attending the demonstration was Jeremy Leggett, founder of Solar Century, which has also launched a legal challenge to the FiT reductions.
“I’m cautiously optimistic that this mass rally, with all the MPs it has reached, plus other pressure, such as the CBI’s supportive position, will make the government think twice,” Mr Leggett told H&V News after the event.
“They may yet thank us for it. They are, after all, in the process of blowing off their own foot in their flagship causes: the Big Society and job creation via participation in the green revolution.”
Solar Century Holdings was the first to file an application for a judicial review of the FiT reductions, challenging the 12 December deadline.
Prospect Law director Edward de la Billiere, representing Solar Century, said: “We have applied for an expedited hearing, because time is of the essence.
“The announcement of the 12 December deadline had an immediate impact on the HVAC industry and consumers across the country.”
Solar will argue that the consultation has been pre-decided, the six-week deadline given was unrealistic and the government had indicated that cuts would not be retrospective.
Friends of the Earth and HomeSun have also filed applications and Mr de la Billiere said both had applied to join the Solar Century action. A number of other companies have also joined the action, including Encraft.
