Optimal Sun Angle For Solar Panels

Here two simple methods for calculating approximate solar panel angle according to your latitude.

Optimal sun angle for solar panels.

Calculating the optimal solar panel angle. The angle of your solar array is an important factor in maximizing your energy production. To get the best out of your photovoltaic panels you need to angle them towards the sun. As a general rule of thumb keep in mind that the panels need to be more vertical during winter to face the lower sun directly and more tilted towards the ground during summer to face the higher sun.

This is because it s based on the average position of the sun over your property. Solar panel angle by zip code. Most solar arrays are installed at a tilt. 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. 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. Optimum angle differs during winter months. 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.

Calculating the ideal angle for your solar panels is not that difficult. 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.
