Maximum Roof Pitch For Solar Panels

Trackers are structures which hold the solar panels in order to move and or tilt them according to the position of the sun.

Maximum roof pitch for solar panels.

At this level the solar panel can lie flat on the roof and get enough sunlight to produce enough electricity. This is a good option if the house roof cannot support the panels or there is a building with a better roof angle for maximum sun exposure. The angle of your roof actually has less impact on solar panel performance than the direction your solar energy system faces. They cannot be mounted on a slanted roof.

Depending on the pitch of your roof tracking panels may not be an option for. Many roofs are going to have slopes between 30 and 40 degrees which means that solar panels can lie flush against the roof and produce enough electricity for attractive returns. Good news solar panels can be installed on low pitch roofs. Optimal electricity production occurs when solar panels face south at a tilt equal to 30.

Most australian homes have a roof pitch of 20 to 30 which is considered optimum for maximizing solar power generation. However they may produce less energy than panels installed on higher pitched roofs. The orientation of the panels and the angle they are tilted will have a greater effect on annual energy production. Tracking panels live up to their name they track the sun as it moves through the sky each day.

If you are trying to install solar panels on a steep roof it may not be possible to place panels at the optimal tilt with traditional racking systems. Of course some roofs will not allow this pitch but installers will try where possible to get as efficient a pitch as possible. Fixed or tracking solar panels. When you want to install solar panels it is vital to understand certain features of the roof and the solar panels.

However even if you lower the tilt of your roof all the way down to 5 production only decreases by about 10 percent. There are two types of solar panel mounting options. A solar panel roof load calculator helps you to establish the size and the weight of the solar panels that your roof can accommodate. In case the roof is very steep you may not be able to get the most optimal tilt angle for the panel especially if it is lower than the angle of the roof.

You will notice that flat roofs with solar panels don t have the panels flat on the roof they are fitted on brackets that tilt the panels to around 30 degrees. However the panels can be installed anywhere between 10 to 35 deg with negligible efficiency loss.
