Cleaning our Panels

Posted by Simon in Financial, Solar Panels, Tips and How-To

Some installers claim their panels, if placed on steep pitch will ‘self-clean’. I’m not so certain about this.

Monitor Meter Mayday!

The latest feed-in tariff table

It took a little while to find this table but it gives you all the latest tariffs after the 3.1% RPI adjustment.
For most of us household users a simple way of calculating the income due is to multiply our kwh generation by the feed-in tariff plus half of the published export tariff. For example, if your retrofit system dates from 2011 , is less than 4kwp then the income henceforth would be kwhs generated X 48.46p (i.e. 46.81 plus half of 3.3).
So 1000kwhs would produce £484.60. Happy generating!

The recent run-in that the Government had over its decision to reduce the tariff for new installations has served to reinforce just how obligated by law they are to pay you the agreed tariff when you buy them. Recent court decision has shown that it is illegal for the government to give short notice of impending changes to future tariffs let alone try to change the tariff for existing roof panel owners!
