How To Position Solar Panels On Roof

The optimum place to install solar panels usually depends on the position inclination and its orientation towards the sun.

How to position solar panels on roof.

Only top manufacturers give warranties on panels installed at an angle of fewer than two degrees. If you are looking to achieve cost savings by installing your own solar power system it is highly recommended that you put some time aside and carefully analyze and determine the the right location for your solar panels. If the place is located in the northern hemisphere of the earth then the solar panels should face south. However solar panels can be orientated on any roof that faces south of either east or west.

Usually this is the best direction because solar panels will receive direct light throughout the day. Generally it s common knowledge in the solar industry that these south facing panels should be tilted between a 30 and 40 degree angle. When installing solar panels on your flat roof the resulting product can be tilted or not. Panels mounted on a standard pitch roof facing east or west will produce approximately 15 less output than panels mounted on a south facing roof of a standard pitch.

The roof is usually a wide open space free of obstacles the wiring and battery storage is easy to keep waterproofed if it is dropped beneath the panels and the panels themselves are less likely to get damaged from incidental contact. Trackers are structures which hold the solar panels in order to move and or tilt them according to the position of the sun. Therefore directions like southwest or southeast are fine. On the other hand places located in the southern hemisphere of the planet must face north for maximum energy performance.

Solar panel tilt angle. In the northern hemisphere the general rule for solar panel placement is solar panels should face true south and in the southern true north. There are a number of reasons for this. There are two most pressing factors in the design of a successful solar panel system generating maximum electricity.

However solar trackers can be used on a ground installation or on a flat roof. For the us your solar panels should face south. They cannot be mounted on a slanted roof.
