What Size System Do I Need?
It depends on how much electricity you use. Two homes the exact same size will use different amounts of electricity and therefore require different size systems. Major electrical loads within a home are air conditioners, electric heaters, pools, and other heating elements or motors.What Size Solor System work Need
That being said, an average 2,500 sq. ft. single-family home uses about 5,000 kilowatt-hours of electricity per year. A 3 kilowatt (AC) system will generate nearly all the electricity required for such a home on an annual basis. Sometimes a PV system is installed that is slightly over-sized to allow for the possibility of a growing family or other factors that may play a part. When a system overproduces electricity, the unused portion is fed back into the grid and will actually be credited back to your utility account in a program called net-metering.
The Solar Company’s solar power systems require approximately 65 sq. ft. of panel area to generate 1 kilowatt of electricity. The SunPower solar panels used in our power systems have a 40-year design life and come with a 25-year warranty.
The actual amount of electricity produced is dependent on how much solar energy reaches your site. An optimally located array would face south and have nothing obstructing the sun’s rays from reaching the solar panels. Actual system production can easily be calculated with a site analysis.
Although most of these substances are harmless in the short term without cleaning they can build up and cause issues for your panels. Not only will your panels look ugly and diminish the look of your exterior, it can also mean difficulty with the functioning of the panels. Your panels may reduce the energy disposition to your home.
However cleaning your panels shouldn’t be a weekly activity, your cleaning schedule for your panels should be dependent on your intuition and look of the panels. If you live in a rural area and nature is harsh towards your panels then you may need to clean them more regularly than other solar panel owners. If the panels are covered in dirt or muck then you should definitely give them a thorough clean and make note of how long it takes for them to get back into this condition.
