Solar Panel Area Equation

For instance if the surface area is 1 500 square meters and the rating of the panel is 250 watts you would divide 250 by 1 500 and then multiply by 100 to find the percentage for this example the solar panel in question would have an efficiency rating of 16 67 250 1500 x 100 16 67.

Solar panel area equation.

Total area 1 0 18 5 56 m 2. To calculate the efficiency of your panel just multiply the amount of sunlight that hits the earth s surface in your area known as the incident radiation flux by the area of your panel measured in square meters. For los angeles a solar panel tilt of 19 degrees works the best. Plugging these number in the above equation we get.

We have a 60 watt solar panel that has an imp amps maximum power point of 3 49. 2 67 0 8 3 34 amps. An 1000 max lb 15 2 a where a is the effective wind area of the solar panel lp wp and lb is the minimum of. The theory of solar cells explains the process by which light energy in photons is converted into electric current when the photons strike a suitable semiconductor device.

Calculate the expected annual energy production. The efficiency of the system is 0 75 and the average annual solar radiation is 1487 kwh m2. 3 86 x 1 25 4 83. Using the above equations.

For a precise method use the second formula on this page to calculate tilt angle. Lb 0 4 30 38 875 0 5 30 36 416 lb 13 66 ft an 1000 max 13 66 15 2 5 4167 3 25 an. For instance in the san francisco bay area the best solar panel tilt angle is between 22 23 degrees. The 60 watt solar panel has a short circuit amp rating isc of 3 86 amps.

120 solar modules each of 250 w p and area of 1 67 m 2 are connected to form a pv system. I can use a 5 amp or larger charge controller with this panel to charge the battery. Look at the 60 watt panel top of the page. A total solar panel area m 2 r solar panel efficiency h annual average solar radiation on tilted panels shadings not included.

The next thing we need is the normalized wind area which is defined as. The theoretical studies are of practical use because they predict the fundamental limits of a solar cell and give guidance on the phenomena that contribute to losses and solar cell efficiency. 1000 watts total area x 1000 watts m 2 x 0 18. You need to divide the number of watts at which the panel is rated by the total surface area of the panel.
