Solar Panel Tilt Angle Australia

The orientation of the panels and the angle they are tilted will have a greater effect on annual energy production.

Solar panel tilt angle australia.

Solar panels generate maximum power when they are positioned perpendicular to the sun so that the suns rays hits the panels on a 90 angle. This solar angle calculator tells you the optimum angle to get the best out of your system. If your latitude is between 25 and 50 then the best tilt angle for summer is the latitude times 0 93 minus 21 degrees. In australia and the southern hemisphere rooftops that face the north sun perform best and generate the most energy.

If you are going to adjust the tilt of your solar panels twice a year and you want to get the most energy over the whole year then this section is for you. Finding the optimal tilt for your solar panels. Pick one angle and leave it alone or adjust the tilt a few times per year to optimize seasonal production. On the contrary in the countries of the southern hemisphere such as south africa and australia the best orientation is true north.

Since solar panels are more productive when the sun s rays are perpendicular to their surfaces the certainly best orientation is the one directly true south azimuth angle 180. In 7 of australia s 8 capitals the best angle is at least 3 degrees less than the latitude. Blantyre is at 15 degrees south almost at the same latitude than darwin in australia. If you are looking to install a typical solar power system on a normal sloped roof this information may not be much use to you.

Depending on your preference here s our advice. The summer optimum tilt angle on the other hand will be 34 15 19. You have a couple options here. The optimum angle varies throughout the year depending on the seasons and your location and this calculator shows the difference in sun height on a month by month.

We are considering to install solar panels on the north and south facing side of the roof. However the panels can be installed anywhere between 10 to 35 deg with negligible efficiency loss. The roof is tilted at about 15 degrees. In australia common roof pitches are 15 or 22 5 so your modules will most likely be mounted at one of those angles.

The following table gives the best dates on which to adjust. What if you have a flat roof. Most australian homes have a roof pitch of 20 to 30 which is considered optimum for maximizing solar power generation. There is no shading from either side.

The other half of the equation is finding the vertical angle or tilt of your solar panels. To get the best out of your photovoltaic panels you need to angle them towards the sun. For instance if your latitude is 34 the optimum tilt angle for your solar panels during winter will be 34 15 49.
