The amount of solar savings you will see on your utility bill each month depends on a variety of factors, including solar system size, energy use, roof exposure, and local electricity costs. System size/energy use: Installing a larger solar PV system that offsets a major portion of your electricity usage will result in higher savings on your electric bill than installing a smaller system that only offsets a minor portion of your electric bill because less power will be pulled from the grid. Roof exposure: If you live in a sunny area, your solar panels will produce more energy than they would if you lived in a shady or cloudy area. More sun means more savings on your energy bill. Local utility rates: If you live in a state with steep electricity rates, you’ll see higher dollar savings on your bills than you would if you lived in a state with lower electricity prices. The easiest way to figure out exactly how much you can expect to save on your electricity bill each month is to obtain quotes from the solar companies that you are interested in doing business with.
