A blog all about the 3kWp PV Solar panels installed in Nov 2011 in Kent UK by Solar Advanced Systems. Follow the ongoing performance and how much solar power we generate over the next few months as well as the problems and solutions we encounter along the way such as solar panels electric meter going backwards.
We are registered with British Gas for our FIT payments and our roof is SSW facing. We have 14 x Sungrid 215W solar panels and Sunny Boy 3000HF inverter.
After 12 months of of having our solar panels we have now reached that landmark of one year's solar generation. The annual output from our PV Solar Panels has surpassed even our wildest expectations and despite what was estimated to be the worst summer for 100 years we still generated 3095kWh of electricity over the year.
Rain falling on our solar panels
Rain on our solar panels was a common sight this year but even with the appalling summer weather we still generated 30% more than the SAP 2009estimates given with our quotes. The generation varied from 0kWh for a snowy day in February to 20.6kWh for the sunniest summer day. You can read more details here of solar panel UK output records
One Year Later: Annual UK Solar Panel Output
Without the inverter error in August I would expect our solar panels to have generated 3250kWh over the year which would equate to 1083kWh per kWP of solar panels. This is substantially above the normal estimates for the UK of around 800-900kWh of electricity per kWp of installed solar panel capacity.
