Best alignment for solar panels.

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. Your solar panel orientation is very important when it comes to maximising the amount of electricity that your solar panels will produce. Find the best angle for optimizing solar collection during winter when solar energy is most scarce by multiplying your latitude by 0 89 and then adding 24 degrees. Therefore to get the very best out of your photovoltaic panels you would typically face them due south at the optimum angle so that the panel is receiving as much sunlight as possible at this time.

South facing panels produced a 54 percent peak reduction overall while west facing solar pv panels produced a 65 percent peak reduction. For starters there is no single ideal angle for solar panels. In general there s one big rule. Therefore the best angle for your solar panels is the one that allows the panels to get the most direct perpendicular light.

Overall the angle of your rooftop has less impact on solar panel performance than the direction your roof faces. However if you live in an urban area in the united states you might just be able to find the best angle for the photovoltaic panels with your zip code. Solar panels produce electricity when sunlight hits their surface and they produce the most energy when that sunlight is exactly perpendicular to the panel face. Or elsewhere in the northern hemisphere the best direction for solar panels to face is true south though there is an exception.

Now all of this is very important for utilities and legislators who are in charge of offering incentives for solar power or other measures that could reduce electricity demand at the height of the day. In the northern hemisphere the sun is due south at solar noon. Ideally a fixed roof mounted solar energy system should be at an angle that is equal to the latitude of the location where it is installed. If you are using a compass to orient your panels you need to correct for the difference which varies from place to place.

At different times of the year the optimal angle may be slightly or even significantly different. As we re in the northern hemisphere the best solar panel orientation is obviously south but.
