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.
How to position solar panels on roof.
On the other hand places located in the southern hemisphere of the planet must face north for maximum energy performance.
For the us your solar panels should face south.
When installing solar panels on your flat roof the resulting product can be tilted or not.
Usually this is the best direction because solar panels will receive direct light throughout the day.
Solar panel tilt angle.
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.
An optimum tilt angle and orientation of your solar panels on a flat roof will ensure top energy production performance of your system.
However solar panels can be orientated on any roof that faces south of either east or west.
However solar trackers can be used on a ground installation or on a flat roof.
There are two most pressing factors in the design of a successful solar panel system generating maximum electricity.
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.
Therefore directions like southwest or southeast are fine.
Only top manufacturers give warranties on panels installed at an angle of fewer than two degrees.
There are a number of reasons for this.
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.
In the northern hemisphere the general rule for solar panel placement is solar panels should face true south and in the southern true north.
Trackers are structures which hold the solar panels in order to move and or tilt them according to the position of the sun.
They cannot be mounted on a slanted roof.
