Tips when buying
Choose a reputable manufacturer of both solar panels and the inverters. The brand panels provide long warranties because of the capabilities that the panel can provide. There can be up to 25 years warranty.
Informe your insurance company that the panels should be included in the insurance of the house.
On flat roofs the panels are confirmed by an aluminum frame and tile work. Depending on geographical location, the height of the roof, the ballast should be adjusted accordingly. Your dealer can get a good source of information. Make sure that you are sure your flat roof can bear the weight! Do you have a pitched roof panels, they’ll be anchored to frame work and the roof itself, and plays no further role ballast.
Putting on a flat roof is easy to do in steps:
– Make the roof clean of dirt and gravel;
– place 4 to 6 pieces of rubber granules on the roof;
– place the light box / frame structure on the roof;
– put enough ballast in the tank
– lay it on the light panel / frame construction;
– secure the panel with supplied bolts and eye nuts to the light box / frame construction;
– Instead the cabling between the panels and make sure the connectors and close properly
– Make one pass through the roof for example danwel the wall;
– enter the cable (2 pieces per string, namely the positive and the negative pole)
– Connect to the inverter;
– turn on the inverter by plugging the inverter into the mains to connect.
Set between the inverter and the mains power meter good. This allows you to periodically measure the yields. In several (equal) Strings (string = set of panels on a converter) can be as reasonable or would result in significant differences for wear / aging. Nice to see how your production will recover in winter!
