Weatherwatch: a bumper year for solar power, thanks to sunny spring and lockdowns

Photovoltaic panels pay off for those who get feed-in tariffs but home installations have dried up without incentives

This year's electricity output from the solar panels on the house roof is already well past the previous record since their installation 10 years ago. Part of the reason is the exceptionally sunny spring, plus the lack of pollution following lockdowns. Particularly significant in Bedfordshire is the curtailment of air traffic that in certain weather conditions used to leave contrails crisscrossing an otherwise clear blue sky.

A decade ago photovoltaic solar panels were expensive and generous government feed-in tariffs were needed to encourage the industry. Those who took the plunge should have got their money back by now and, if my local estate agent is to be believed, added several thousand pounds to the value of their property. Solar panels give a home an income, often more than 1,000 a year.
