Solar Energy Installation and Residential Solar Power Systems
Solar energy installation [http://freeenergymagnetmotor.com/solar-energy-heating-in-solar-energy-homes] can be installed by an expert but with the right guidance any reasonable handyman could install them himself with a little assistance from friends or neighbours.
Solar Panel Installation
Panels are usually mounted on the roof of a building. However, they can be placed on a stand-alone rack if necessary. The distance between mounts should be about 48 inches and they should be placed in a straight line.
The mount should never be attached directly to the plywood sheathing of the roof. Panels should be placed at a location where the sun shines for the longest duration each day. This is important because they tend to lose their efficiency even in partially shaded areas.
The direction in which the panels are facing is also very important in solar energy installation. South is best, east or west is the second best choice; north is not an option. However, you will need more panels to generate the same amount of energy if they are facing east or west.
Before installation, make sure that you have the necessary building permits. Find out about building requirements from your local building or zoning department.
Tilt the panels according to the latitude for maximum sunlight exposure. Panels installed at 0 to 15 degrees latitude should be tilted 15 degrees. The tilt is same as the latitude for 15 to 25 degrees. For each additional five degrees of latitude up to 40 degrees, an extra 5 degrees of tilt should be added to the latitude. At 40 degrees and above, 20 degrees of tilt is added to the latitude.
Mounts should be placed directly on top of a rafter. A block of wood can be used if a rafter is not available. However solar panels can also be preassembled in groups which makes it easier and quicker to install them, because you have less individual units to deal with when on the roof and a lot of the initial work can be carried out on the ground with some assistance from friends.
