The PV system (Photo Voltaic System) has a power rating of 3500 Watt peak.

In this system you first have to place a lot of metal hooks on the roof. This is done simply by shifting a roof tile upwards, and place the hook around the tile + lath below it. I had to bend all hooks slightly outwards, to let them fit around the tiles.<\/p>\n<p><a href=\"http:\/\/www.olino.org\/wp-content\/uploads\/2009\/03\/s6300675-1.jpg\" class=\"thickbox no_icon\"><img decoding=\"async\" loading=\"lazy\" src=\"http:\/\/www.olino.org\/wp-content\/uploads\/2009\/03\/s6300675-1-400x300.jpg\" alt=\"s6300675-1\" title=\"s6300675-1\" width=\"400\" height=\"300\" class=\"alignnone size-medium wp-image-4016\" \/><\/a><br \/>\n<em>The ClickFit System for Mounting the Solar Panels<\/em><\/p>\n<p>Then support rails are clicked onto the hooks.

The cable coming from the inverter of the PV system is connected to the electricity grid. A loop is taken up in the cable.

For the year 2009 the subsidy is \u20ac 0.29 per kWh. Besides that, you also save the cost of the electricity.<\/p>\n<p>To calculate the payback time of the system, I made a excel file in which I compare the yield of the PV system with the yield of a savings account. I tried to take as much as possible relevant factors into account. The calculations are based on the Dutch subsidy system, and Dutch tax system. In my case the pay back time is about 13 years.
