The Solar Trade Association is calling for the National Grid to look again at its predictions for solar power in coming decades.
In forecasts published by the grid operator, the National Grid’s statistics on current and future solar arrays are said to fall far below other estimates and need to be revised upwards.
Solar Trade Association chief executive PaulBarwell commented: “It is frustrating that both the Government and the National Grid are basing important decisions on out of date data. This undermines what the solar industry has achieved so far and risks holding back solar’s potential.
“The number of solar installations in place is higher than in official statistics.
“The cost of solar has fallen dramatically. We forecast that solar will become cheap enough to compete without public subsidy by the end of the decade, but only if it has a stable policy framework. Using accurate data is an essential part of that.”
Analysis undertaken by the Solar Trade Association shows that solar power will match onshore wind on price by around 2017/18.
Mr Barwellsaid: “Solar could one day in the future meet a third of UK electricity needs from south-facing roofs and facades alone. The National Grid needs to recognise solar’s huge potential to generate a sizeable chunk of the UK’s power.”
