Solar Energy Industries Association (SEIA) (SEIA, 2017), the number of homes in Arizona powered by solar energy in 2016 was 469,000. The grid-connected system consists of a solar photovoltaic array mounted on a racking system (such as a roof-mount, pole mount, or ground mount), connected to a combiner box, and a string inverter.
A PV cell, commonly called a solar cell, is an electronic device designed to harness the energy from photons of light and convert it into electrical energy. This conversion process is achieved through the photovoltaic effect, whereby the solar cell generates an electric current when exposed to light.
• Photovoltaic System Lifespan: This is the expected lifespan of the photovoltaic system in years. This is used to calculate the effective cost of electricity for the system. If the photovoltaic system lasts longer, the cost of electricity will be proportionally lower. Power purchase agreements with grids are generally for 20 years.
Number of panels = system size/production ratio/panel wattage. Plugging our numbers in from above, we get the following: Number of panels = 10,791 kWh / 0.9 or 1.6 / 400 W …which gives us between 17 and 30 panels in a solar array, depending on which production ratio we use (17 for a 1.6 ratio and 30 for a 0.9 ratio).
One of the first questions homeowners ask when going solar is "How many solar panels do I need to power my home?" The goal for any solar project should be 100% electricity offset and maximum savings — not necessarily to cram as many panels on a …
