Solar Panel Tilt Calculator

Calculating the optimal solar panel angle 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.

Solar panel tilt calculator. Most solar arrays are installed at a tilt. The solar panel tilt also depends on when you want the panels to produce the most energy. The other half of the equation is finding the vertical angle or tilt of your solar panels. You have a couple options here.

The angle of your solar array is an important factor in maximizing your energy production. Depending on your preference here s our advice. Unlike a calculator that determines your solar panel angle by zip code a sun angle calculator that permits four changes throughout the year ensures the highest possible efficiency for your solar power system excluding of course the use of a solar tracker. 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.

Depending on where you live the best angle at which you should install solar panels will change. For this calculator latitude is positive to the north and longitude is positive to the west of the prime meridian. If you cannot change the angle of your panel throughout the year angle your panel according to the time of year that you need to get the best performance out of your system. If you can change the angle multiple times a year you may get great output throughout the year.

The calculator shows the degrees from vertical. Adjustable x4 for maximal efficiency. For even more precise angling you would need to track the sun as it moves throughout the day on a minute by minute basis. Here two simple methods for calculating approximate solar panel angle according to your latitude.

The violet line is the solar energy per day if the panel is fixed at the winter angle discussed below these figures are calculated for 40 latitude. Finding the optimal tilt for your solar panels. Fixed tilt in this mode of fixed tilt there is no need to move your solar panels throughout the year. Solar panel angle calculator.

This is because it s based on the average position of the sun over your property. Solar panel angle calculator. Solar panel angle by zip code. If your solar panels will have a fixed tilt angle and you want to get the most energy over the whole year then this section is for you.

Pick one angle and leave it alone or adjust the tilt a few times per year to optimize seasonal production. The optimal angle for your solar panels 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.
