How Much Sun Would My Solar Panels Get

While some states in northern latitudes get less than 4 hours of sunlight per day on average others can get more than 7 5 hours.

How much sun would my solar panels get. Solar panels indicate how much power they intend to produce under ideal conditions otherwise known as the maximum power rating. But how much electricity your solar panels produce depends on several factors. The higher the wattage rating the greater amount of power your solar installation will produce. Solar power systems are very custom based on the home roof type shading and utility.

A home that consumes 1 000 kwh per month will normally need between 20 and 30 solar panels. Although your panels may get an average of 7 hours of daylight a day the average peak sun hours are generally around 4 or 5. Most residential solar panels have power output ratings from 250 to 400 watts depending on panel size and how well they convert sunlight into energy. In terms of power output it is best to separate solar panels into two categories.

The number of peak sun hours you get per day increases the closer you are to the equator and typically during the summer months. But it s still possible to enjoy the benefits of solar even in places up north. Obviously the more sun the better. The exact number changes depending on the specifications of the chosen panel model as well as the sunshine available at the project site.

Solar radiation peaks at solar noon when the sun reaches the highest point in the sky. So the kwh divided by the hours of sun equals the kw needed. Installation of panels for the average 5kw system ranges from 11 100 22 400. Solar panels need direct sunlight in order to produce the maximum solar output.

Solar panel efficiency typically ranges from 15 to 20 percent but high end solar panels like sunpower can offer efficiency levels as high as almost 23 percent and above. You need a sunny roof to benefit from solar panels but yours may be sunnier than you think. 60 cell solar panels are typically 5 4 feet tall by about 3 25 feet wide and have a power output in standard test conditions of between 270 watts to 300 watts depending on the exact efficiency of the cells in them. In a state with strong peak sunlight a panel with lower efficiency will likely do the trick.

60 cell solar panels and 72 cell solar panels. Solar panels are rated based on the watts they generate. Google s project sunroof gives building by building details and now has data for parts of all 50. Or 30 kwh 5 hours of sun 6 kw of ac output needed to cover 100 of.
