One benefit for photovoltaic (PV) solar energy systems is that the annual peak of the solar resource (and a PV system’s output) occurs on sunny summer days. This corresponds exactly with utilities’ highest energy demand periods – and their highest energy charges.
During the winter in the north east there is less sun per day available to power PV systems. However, on clear days with snow cover, there is up to a 60% output increase from light reflected off snow. And the efficiency of crystalline PV cells is improved in the cold. Thus on cold, sunny winter days, crystalline PV systems will have their highest output.
Solar benefits also stem from generous incentives offered by the state and federal government, rapidly rising electricity costs, and rapid advancement of solar technology.
Solar electricity systems have no moving parts, so they have a very long lifetime, and are virtually maintenance-free.
Systems can also be customized to exactly suit specific load requirements and later expanded in modular fashion. The modularity allows you to invest exactly according to your current needs.
In addition to stabilizing energy costs, solar energy is also an attractive investment due to the added resale value it gives a home. In today’s increasingly tight housing market, a home with a solar electric system is “cheaper” to live in and thus is very appealing to potential buyers.
