It's not so long ago that solar power and Scotland were most likely to come together in the setting up of a joke.
Suggesting in earnest that Scottish homes could rely on the sun for energy would have got you marked down as not the brightest spotlight in the ceiling.
However, times are changing, and increasing numbers of our homes are changing too. Tens of thousands of Scottish households have now installed solar panels, a result of better technology, cheaper systems and a realisation that it is hours of daylight not of sunshine that count.
New analysis of the weather in April has demonstrated that homes with solar panels installed were able to generate 100 per cent of their electricity needs over the month, and generate a small surplus. Monitored homes managed to generate 99 per cent of their hot water requirements too.
This experience is not uncommon. WWF Scotland says tens of thousands of homes with panels installed are finding the same. Despite warnings that a cut in government tariffs for purchasing electricity would kill the industry, companies providing solar panels have done well, with a reduction in the cost of systems helping keep demand healthy.
The time it takes to see a return on the cost of equipment remains a barrier, but it is coming down all the time. Scotland is warming to solar.
Why are you making commenting on The Herald only available to subscribers?
It should have been a safe space for informed debate, somewhere for readers to discuss issues around the biggest stories of the day, but all too often the below the line comments on most websites have become bogged down by off-topic discussions and abuse.
heraldscotland.com is tackling this problem by allowing only subscribers to comment.
We are doing this to improve the experience for our loyal readers and we believe it will reduce the ability of trolls and troublemakers, who occasionally find their way onto our site, to abuse our journalists and readers. We also hope it will help the comments section fulfil its promise as a part of Scotland's conversation with itself.
We are lucky at The Herald. We are read by an informed, educated readership who can add their knowledge and insights to our stories.
That is invaluable.
We are making the subscriber-only change to support our valued readers, who tell us they don't want the site cluttered up with irrelevant comments, untruths and abuse.
In the past, the journalist’s job was to collect and distribute information to the audience. Technology means that readers can shape a discussion. We look forward to hearing from you on heraldscotland.com
