Are solar panels a good investment?

Energy minister, Greg Baker, has claimed that installing solar panels would deliver a better financial return than a pension.

Leonie Greene from the Solar Trade Association told BBC Radio 5 live's Dominic Laurie: "There's no wear and tear so actually it's an incredibly long-lasting technology."

However consumer expert Martin Lewis warned that although solar panels were guaranteed for 25 years, the companies selling them could have disappeared in that time.
