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. In particular bird droppings will probably have a disproportionate effect on panel performance but are difficult to remove by a power hose for example unless you act quickly. And even the most passionate solar power owners do not spend all day staring at their panels!

Monitor Meter Mayday!

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

(This happened in May so I thought you’d forgive the headline.)
I’d been away for a few days and also the weather continued its gloomy theme. You know what its like –there are some days when you just don’t want to know how little your panels are producing (although it’s quite impressive how much they still generate despite the murk) – and busy travelling around so solar is not first thing on your mind.
However I eventually thought it was time to put another reading into www.onyourroof.com when- horror of horrors – the monitor was flatlining! Continue reading “Monitor Meter Mayday!” »

The latest feed-in tariff table

Posted by Simon in Financial, Solar Panels

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!

April 1st – Don’t be fooled

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

April 1st is an important day for solar microgenerators  (the posh term for you and me and other UK users of OnYourRoof.com).  Lest we forget, it’s the day that the feed-in tariff allocated to your installation is increased by RPI inflation. So it’s also a very good day to log on to OnYour Roof.com and enter your meter reading. Continue reading “April 1st – Don’t be fooled” »

National Solar Centre – Cornwall

Posted by Simon in Uncategorized

I was at the launch of the National Solar centre last week. It was held in the grandeur of the Academy for Engineering just off Pall Mall and Greg Barker (Climate Change Minister) came along between Parliamentary debates to give it his blessing – so it must be important and I’m glad I was there.

OnYourRoof in action!

Posted by Simon in Uncategorized

We expect your panels were probably bought with at least the next 10 years in mind. So the website is here for the long term to support its users and would hope that early on in its life we do not have too many problems to solve. Its first goal is to build a big database so our users can have ever more accurate and reliable benchmarks to assess how their panels are performing over time. So it came as a bit of a surprise to be called into action by our very first user! Continue reading “OnYourRoof in action!” »
