Solar Panel Optimal Height

If you are trying to install solar panels on a steep roof it may not be possible to place panels at the optimal tilt with traditional racking systems.

Solar panel optimal height.

That means your solar panel would look like this. The table below features a solar panel angle by zip code for at least one city from every state. The optimal tilt for solar panels is perpendicular to the light source. The average size of solar panels used in a rooftop solar installation is approximately 65 inches by 39 inches or 5 4 feet by 3 25 feet.

Select a location from the city pulldown menu or select enter lat long from the pulldown menu and manually enter the latitude longitude and time zone information in the appropriate text boxes. Solar panel angle by zip code. There is some variation from brand to brand and if you re installing a large scale solar panel system such as for a warehouse or a municipal building your panels will be closer to 6 feet long. Shading depends not only on panel tilting but also on the height that panels are placed relative to each other.

The subsequent mathematical operation remains unchanged. Tracking or optimal tilting and 2 axis equipment is more expensive than is 1 axis equipment or optimal tilting. Many roofs are going to have slopes between 30 and 40 degrees which means that solar panels can lie flush against the roof and produce enough electricity for attractive returns. For example panels that track the sun placed on a south.

The result for chicago is 90 42 23 25. This page doesn t discuss tracking panels solar panels should always face true south if you are in the northern hemisphere or true north if you are in the southern hemisphere. Your life would be much easier if you could just find out what angle is the optimal solar panel angle in your city or county. Panels that track the movement of the sun throughout the day can receive 10 in winter to 40 in summer more energy than fixed panels.

For this calculator latitude is positive to the north and longitude is positive to the west of the prime meridian. While you can use solar panel trackers to keep them at the optimum angle at all times the costs and complications involved aren t worth it in most cases. To generate the most electricity you would tilt the solar panel so that it s perpendicular to the light source. 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.

To calculate the sun height at midday during the winter solstice instead of subtracting we must add 23. I know that middle school was a long time ago so i ll clarify that perpendicular means a 90 angle. To get maximum energy efficiency during the winter solstice the solar panels in chicago must face south and be tilted 65 90 25.
