Planning for solar panels

Living in a listed building or conservation area doesn't mean that you can't have solar panels, as Anne Robbins' experience shows. You may, however, need determination and energy, and money for an appeal, if you want to leap over all the planning hurdles. Anne lives in a conservation area in Gre…

They are more efficient than other types of collector as they are almost perfectly insulated, and heat cannot pass through a vacuum. As the tubes are cylindrical, they are always perpendicular to the sun reducing the amount of…

Posted by Cathy Debenham on 16 December 2008 at 4:20 pm

Get a few people with solar panels together (as happened this weekend) and inevitably there's discussion about how to get the most out of your solar thermal system.

How much of my hot water can I get from the sun?

Posted by Gabriel Wondrausch on 13 December 2008 at 9:01 am

Have you ever wondered how much energy falls on your roof each year? Well probably not, but it is really quite interesting. The average UK house with a south facing roof of 30m² will be exposed to around 30,000KwH of the sun’s radiation every year. When you compare that to the amou…
