A couple of years back (probably a lockdown activity) I did the maths on a set of solar panels. Over the 25-year life, ignoring feed-in tariffs and assuming a fixed energy price, I would be around £500/6 months energy better off.
However, just as with cavity wall insulation back in the 1980s and 1990's, the only way for utility-delivered energy prices to go is up; so not really much of a gamble, with recent events simply accelerating the trend.
To me the addition of batteries massively enhances the value of solar panels and from the initial data have a much shorter time before they break even. Only issue my friend now has, is the battery pack in the cupboard under the stairs and the fire hazard it presents...
