HOW IT WORKS


Roof-mounted solar collectors convert solar energy into direct current, which is in turn converted into 230 V alternating current using an inverter. This current is then fed into the public electricity grid and remunerated by your energy provider at a fixed rate. Energy providers currently pay a higher rate per kWh for the electricity generated than the household must spend for the electricity that it consumes.



WHAT YOU NEED TO KNOW


    For a set-up with output of 1 kWp, a roof surface area of around 8,5 m² is required.
    The dimensions of an average detached house will allow for a set-up with total output of between 3 and
        15 kWp.
    A higher yield is dependent on the geographical positioning of the house and the angle at which the solar
        module is installed (ideally 30-45°). Ideally, the roof and module should be south-facing.
    The solar modules must not be shadowed by dormers, chimneys etc.
    In 2008 and 2009, the Solarworld SW poly series solar modules used by Hanse Haus gained top marks
        in an independent test by German magazine Photon that also evaluated the modules of 16 other
        manufacturers.
