img_2989-547-x-410Because I think that the price of a solar panel is still pretty high(in Europe), and because the stimulation from our government (in the Netherlands) is not so good (very,very complicated and time consuming) I started the project of building my own solar panel. I would like to invite anyone who has some experience with this or is interested in it ,to give me any advice or remarks about it.

Payback period of a PV system

Grafiek besparing PV systeemWith the rising oil prices having an impact on the electricity price it would be interesting to see what the payback period is for a Photovoltaics (PV) system. The result, even for individuals without subsidy it is already interesting to invest in a PV system. A PV system will payback itself way before its guaranteed lifetime and its long-term savings in electricity costs can be 7 times as high as the investment cost (based on Dutch prices). For my own PV system of 2500 Wp, I would have a net cost saving of more than € 68,000 on electricity costs after 25 years.
