The cost of a 50kW commercial solar photovoltaics (PV) system in the UK has now reached a price range of £100k to £130k. With the UK feed-in tariff set at 32.9p/kWh generated, I would argue that UK solar PV is currently in a bubble — one that serves up a golden opportunity for businesses to add solar PV to their property. David Owen’s excellent blog post on the new FiT, prices and the future for solar in the UK: Part 1 only serves to underline this point. In my opinion, it is unlikely that there will ever be a better time to act, so my advice would be: fill ‘yer boots!
