Why should I purchase a PV system? People decide to buy solar energy systems for a variety of reasons. For example, some individuals buy solar products to preserve the Earth's finite fossil-fuel resources and to reduce air pollution. Others would rather spend their money on an energy-producing improvement to their property than send their money to a utility. Some people like the security of reducing the amount of electricity they buy from their utility, because it makes them less vulnerable to future increases in the price of electricity.
How long do photovoltaic (PV) systems last? A PV system that is designed, installed, and maintained well will operate for more than 20 years. The basic PV module (interconnected, enclosed panel of PV cells) has no moving parts and can last more than 30 years. The best way to ensure and extend the life and effectiveness of your PV system is by having it installed and maintained properly.
What if I live where it is cloudy a lot of the time? Will solar work here? Despite what many people think, there is more than enough sunlight in all parts of the U.S. for most homeowners and commercial enterprises to make use of solar energy. There really are no “bad” solar sites. Even the rainiest parts of the Northwest where they receive almost half as much solar energy as the deserts of California and Arizona, they receive more than sunlight than Germany, which has made itself a solar energy leader.
What happens when it snows? Will my solar panels still work? Yes. Sunlight will penetrate a thin layer of snow and the snow will usually melt fairly quickly off of solar panels. If you have had a heavy snow you can help it along by using a squeegee on a pole to scrape off the surface layer of snow.
Does it make sense to install a solar system if we are moving in a couple of years? Probably. Most real estate experts believe that given the concerns about energy costs a solar system will significantly raise a home’s or commercial property’s value. One source, the Appraisal Journal, states that the value of your property is increased by $20 for every $1 reduction in annual operating costs resulting from installed energy efficiency measures or energy generation systems. However, this benchmark depends on local market factors, so please consult your real estate agent before investing in any upgrades to a property prior to selling it.
