The main advantage of efficient and high-power solar panels is that you can have a powerful solar panel system that takes up very little space. This is an important benefit, especially for houses with limited quantities of rooftop properties facing south. Another benefit of having high rated solar panels like SunPower, LG, and Panasonic is that the degradation rate of high-quality solar panels from these brands will be lower than that of high-quality mid-range panels from other brands.

Over time, lower energy efficiency degradation rates translate into higher energy savings for your household. It goes without saying that the energy efficiency advantage of a given panel needs to be balanced against the total cost of the system, so that you (the homeowner) can achieve the best return on investment. If you plan to stay at home for decades or longer and do not want to damage and reinstall solar panels within 10 to 15 years, investing in LG or Panasonic's high-efficiency photovoltaic panels may prove the best long-term return on investment.trina solar panels
