Why does longitude and latitude matter with solar panels.

Renewable energy potential model empowers users to calculate renewable energy capacity generation and cost based on geospatial intersection with grid infrastructure and land use characteristics. Always related to the latitude and longitude of the geographical point in the globe. So tilting your panels to the midway point will maximize the sun captured throughout the year. This angle varies sinusoidally through the year and is called b0.

Bipv is a solar technology that uses photovolaics in building design. Move your mouse pointer across the parallel lines of energy and then click on one of these zones to temporarily lock it and then select a different month season in the menu at the bottom. Because of the earth s round shape the equator is closest to the sun and the closer you get to the earths poles you get further and further from the sun. Earth crosses the sun s equator about december 7 and june 7 each year.

Here two simple methods for calculating approximate solar panel angle according to your latitude. In figure 9 you ll see that the further you go to the north. Because your latitude is the same as the angle of the sun in the sky halfway between midwinter and midsummer. That is why they receive the highest level of solar energy.

But the same does not happen on the whole northern hemisphere. Plus since every location is unique. The earth doesn t orbit exactly around the sun s equator so through the year the center of the solar pictures moves up and down a little more than 7 degrees. Horizontal or 0 degree tilt is not the most efficient angle for solar panels but it does allow for seamless integration into building design.

On the daylight side only the point directly under the sun receives full intensity solar radiation. Calculating the optimal solar panel angle. 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. The sun will be about 15 degrees higher in the sky in summer and 15 degrees lower in the sky in winter.

One hemisphere is always dark receiving no solar radiation at all. As you move from the equator to the north the angle of the sun declines. Explore the effect of the angle of incidence on sun s energy.
