Solar Panel Tilt


Solar Installers Perth
Solar panels are usually installed at an angle. They are installed with a tilt rather than installed horizontally. This is to give them the optimal angle towards the Sun, thereby optimizing the power they produce.
The optimal angle of a solar panel depends on the latitude, the distance from the equator. Ideally the panel should be at a right angle to the Sun. This allows the panel to produce the maximum amount of power during good weather. Of course the Sun will be in a different position during the day, so the panel cannot always be in the perfect position. And the sun will also be at a different position in summer and winter. But it is still possible to set up a panel so that it is in a fairly good position for most of the day, during most of the year.

Solar System Perth
In Perth, Sydney, and other cities of similar latitude, the best tilt for a solar panel system is about 30 degrees, facing north. This angle does not have to be exact as a slight variation will only cause a small decrease in total power. Often the panels are simply installed so that they are at the same angle as the roof of the building.

A commercial Solar System will generate 10% to 15% lower energy when the Sun is not quite at the right angle. But this is still more than adequate for most needs. The solar battery system will store energy produced during the sunniest part of the day, with a fair (but slightly lower) amount of additional energy produced during the rest of the day.

It is possible to install tilt frames to optimize the angle of the solar panel system. But this will add to the solar panel cost. In many circumstances this additional cost is not really justified. It is more cost effective to simply install an extra panel or two to increase the total amount of energy produced.

In solar systems installed near the equator the panels are completely horizontal. This is because the Sun is directly overhead. In solar systems installed in places like Tasmania, far from the equator, the panels are installed at an angle higher than 30 degrees. In these situations of extreme latitude the optimal angle is more important, so the correct tilt is achieved with tiled frames around the panel.
A tilted solar panel has an additional advantage in being easier to keep clean. Less dust/dirt accumulates on an angled surface, and rain that runs off the tilted panel will help keep this surface clean.

Solar Power Systems Perth
A solar panels specialist can design a system for any home that replaces the need for power from the main electrical grid. This saves money in the long term, and even provides energy during blackouts.
