Solar panel orientation annual collection.

For example if the location of the solar array is at 50 o latitude the optimal tilt angle is also 50 o. This solar angle calculator tells you by location the optimum angle to get the best out of your system. Solar panels should always face true south in the northern hemisphere north in the southern hemisphere tilted from the hoizontal at a degree equal to your latitude plus 15 degrees in winter or minus 15 degrees in summer. Why orientation matters with rooftop solar in general solar panels that are oriented directly east or directly west will produce about 20 percent less electricity than if they were facing south.

The optimum angle varies throughout the year depending on the seasons and your location. Orientation of the panels while the angle of your solar panels is important a more important factor in your energy production is going to be the direction your panels face. In general there s one big rule. This is because the sun is always in the southern half of the sky in the northern hemisphere.

Proper solar panel orientation for maximizing input requires an understanding of how the sun tracks across the sky in your particular area both daily and yearly see fig. Since you can t export your surplus solar electricity for a feed in tariff it makes sense to optimise the tilt to match your consumption. This arrangement is often called and east west split and has the advantage of producing a more constant output of electricity during the day which can help to increase self consumption. East and west orientation.

The more sunlight reaches your solar panels the more electricity you can generate and the more money you ll be able to save on your electric bill. W d a n portrait d d t sin. For the best results solar panels should be oriented towards the south. Placing some solar panels facing east and some facing west will result in the total amount of electricity produced being around 12 less than if all the modules were placed facing north.

A general rule for optimal annual energy production is to set the solar panel tilt angle equal to the geographical latitude. If you re in the u s. Most solar energy is received when the cell array faces directly towards the sun. To get the best out of your photovoltaic panels you need to angle them towards the sun.

Passive solar does not change the collector surface angle remains fixed. An additional 3 5 though can be gained by evaluating this more carefully.
