Solar Panels


Solar Panels You may recall cost £25,000 for 40 photovoltaic Panels (50% Grant equals £12,500)1st year produced 5000kwatts we consumed 5600 kwatts home and Re-charging Van. Since we started, the rules of the Npower Juice scheme have changed.Initially we were getting 5p per unit produced, whether we used it or not. In April 2006 Npower Juice said for the energy we put into the grid, we would get the secondary rate that we would normally pay for electricity. The first 182Kwh are at 13.68p the secondary rate on all over was 10.11p, We get back 10.11p per Kwatt of energy we put into the grid. This way we use all the energy we produce even if we use it at night!Problem is Npower need to install an export meter and until they do they intend estimating the amount. (I suspect in their favour). Never the less our electric bill is very smallIncreased cost of energy & electricity, has reduced the payback period considerably, I suspect that as prices are inevitably going to increase immensely, we may get our money back within 7 to 8 years? Our house is worth more because of reduced costs. A couple of things to note. The roof of our house is quite steep the result is that the amount generated when the sun is at its highest is not the best production figure. The best rates (5 Kwh) are achieved in spring and autumn when the sun is at the ultimate angle to the roof and solar panels. The performance has not declined over time so the self-cleaning glass must work. Any Questions ask me david@salesprint.co.uk David Webb
