"At a high level, a review of FiTs so soon after their introduction does not help the UK's reputation as a location for cleantech investment.

"The UK's FiT rates are now among the lowest in Europe, certainly for systems of 150kW upwards. At the same time, system prices in the UK are about the highest in Europe. The result is that the returns are likely to be unattractive for most investors and there is a real risk that the solar market for installations above 150kW will stop in its tracks. It could be the death of large scale installations in the uk.

"Other European countries have cut their FiTs and some have capped or stopped funding for large installations, but the UK cannot be compared to these countries. Countries like Germany have 400 times more solar installed than all the renewable energy capacity in the UK. They have stimulated their industry and created jobs – the UK is in another place in that regard.

"The FiTs were meant to stimulate growth and generate jobs, but now all but the most advanced plans for stand-alone farms will be shelved or abandoned. This could force investment to go elsewhere. Businesses and farmers who would have installed solar on their barns and roofs may now pull back.

"It will put a huge dent in the market, and all but the very advanced plans or those who are very experienced would go ahead with a large scale installation now.

"In the absence of capital grants, the FiTs now runs the risk of being a benefit for the wealthy only. They can afford the panels and then receive an attractive return, because the new banding system protects the payback on smaller level installations. 50kW is not really a large system and this could be achieved by a large factory roof or social housing development.

"The other possible impact is that investors and businesses lose their trust in the UK’s intentions towards other renewables and clean technology. This is regrettable given that the driver behind the FiT review was the desire to save £40m in 2013/14. This is a small amount of cash compared to other technologies and equals, for example, the installation of 10 offshore wind turbines

"Fundamentally, the solar market in Europe and in the UK is a roof top market. Over 90% of solar installations in the UK are on domestic roof tops. The impact of the FiTs cut on this sector will be low, but I would expect lower roll-out rates due to higher system prices in the medium term."
