Each solar panel is just a series of solar cells linked all together and encased in a protecting enclosure with a clear face to enable sun to enter and a solid backing. The entire panel is sealed to prevent wetness from breaking down the panel.

Solar power systems can produce adequate electrical power under optimum conditions to power all the lights and electrical home appliances in a common American home as well as to keep warm in the winter season and cool in the summertime. The effectiveness of your solar panels actually depends on your area. Solar power are installed on whichever surface area of your residence gets most of solar exposure-in southern environments this is the north-facing side, and in northern environments it is the south-facing side.

Even if you do not get adequate sun to produce electrical power to please all of your energy needs, you can still benefit greatly by setting up solar panels for your home. The bulk of modern homes with solar panels installed are not entirely off-the-grid.
