How much should I spend on solar panels?

Choosing the best solar panels UK company
Which? consumer watchdog recently carried out an investment into 12 solar companies in the UK. They wanted to discover if properties were assessed correctly and payback time and feed-in tariff earnings were accurate.
Make sure to avoid solar companies carrying out the following:
- Offering a discount which is only valid for 24 hours. Also avoid those providing first-come first-serve deals in exchange for monitoring your energy use. Both of these practices are a breach of code regulations.
- Not going into the loft to check for suitability of solar panel installations. Your roof should be inspected to ensure it’s capable of holding the panels.
- Giving a quote or estimate without having a surveyor inspect your property. Companies sending just a salesman should be avoided.

The which? survey also found that:
- Seven companies failed to take into account that part of the roof was shaded, meaning the solar panel efficiency was reduced.
- Eight made no enquiries into the homeowner’s energy usage or lifestyle to truly determine if solar was a good solution.
- Eight of the companies underestimated payback times because of a flawed methodology under Building Regulations. Use the Energy Saving Trust solar calculator for a more accurate estimation.
