Subsidies on solar panel kits were terminated when it was found most kits
were
used to charge batteries to run the fridge to keep the beer cool in the
allotment shed.

My uncle made a very effective wind generator using an old factory venting
fan turning a car alternator to keep a deep cycle batter charged in an
isolated barn on his Yorkshire smallholding. The only new component was a
decent battery once he proved the system worked using an old one. Even the
12 volt bulbs and holders came from cars in a scrap yard. The end result was
a switchable lighting throughout and now an old caravan fridge keeps the
beer & bait chilled.
