Optimal sun angle for solar panels.

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. Most solar arrays are installed at a tilt. Optimum angle differs during winter months. Calculating the ideal angle for your solar panels is not that difficult.

To get the best out of your photovoltaic panels you need to angle them towards the sun. The ideal angle for your solar panels can vary depending on your solar objectives. Here two simple methods for calculating approximate solar panel angle according to your latitude. 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 basis.

The angle of your solar array is an important factor in maximizing your energy production. For example if you are seeking to maximise solar generation during winter months be it for an off grid system or higher energy consumption levels you would ideally want to angle your panels at a greater tilt for maximum exposure to the low winter sun. As a rule of thumb solar panels should be more vertical during winter to gain most of the low winter sun and more tilted during summer to maximize the output. This is because it s based on the average position of the sun over your property.

Depending on where you live the best angle at which you should install solar panels will change. On the contrary in the countries of the southern hemisphere such as south africa and australia the best orientation is true north.
