How to position solar panels on roof.

When installing solar panels on your flat roof the resulting product can be tilted or not. There are a number of reasons for this. In most cases the ideal position for a solar panel system is on the roof. The optimum place to install solar panels usually depends on the position inclination and its orientation towards the sun.

They cannot be mounted on a slanted roof. There are two most pressing factors in the design of a successful solar panel system generating maximum electricity. Generally it s common knowledge in the solar industry that these south facing panels should be tilted between a 30 and 40 degree angle. This being the case the general best practice to date has always been to position solar panels facing south in order to capture the maximum amount of sunlight overall.

Therefore directions like southwest or southeast are fine. 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. However solar trackers can be used on a ground installation or on a flat roof. Trackers are structures which hold the solar panels in order to move and or tilt them according to the position of the sun.

An optimum tilt angle and orientation of your solar panels on a flat roof will ensure top energy production performance of your system. Only top manufacturers give warranties on panels installed at an angle of fewer than two degrees. 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.

For the us your solar panels should face south. In the northern hemisphere the general rule for solar panel placement is solar panels should face true south and in the southern true north. 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.
