Energy efficiency is a concern for many people for many different reasons. Some people want to conserve energy purely to save money on utility bills, while others conserve energy to lessen their environmental impact. Some even try to conserve energy to become energy independent and get off the energy grid. One of the most popular ways to become energy efficient is to have contractors, like Wilmington roofing companies, install solar panels on the roof to convert the sun's light into electricity.

Solar panels are combined into a solar panel array, which creates an average of four kilowatts of energy per day. An average household uses 3,000 kilowatt hours per year. Solar panel arrays are generally about 300 square feet, and should be positioned to the south for maximum sun exposure. Solar panels will be tilted when installed according to the distance from the equator. The closer the building is to the equator, the lower the necessary tilt, while buildings farther from the equator will have a high solar panel tilt. On average, solar panels in the United States are installed at a 10 to 30 degree tilt.

Solar panels can be combined with batteries to store electricity for use during the night or on cloudy days. When paired with sufficient batteries, it can be possible to not use the public electric grid at all.

However, most solar panels are hooked into the electrical grid, so that homeowners have no interruption of service during dark or cloudy days. When the solar panels generate more electricity than is actually used, the electricity flows to the power company. The power company then pays the homeowner to use the extra electricity, lowering the utility bill even more.

Solar panels require little maintenance and have an average lifespan of 25 years or more. When installed properly, they do not damage the roof, and may even protect it from exposure. The initial cost of installing solar panels is expensive, with the cost ranging from $20,000 to $40,000 for an average residential system. However, tax rebates from the government and some power companies help offset the cost. Solar panels usually pay for themselves with energy savings after seven to fifteen years.

Solar panels save homeowners money while also helping the environment by decreasing the need for energy. Homes with solar panels installed can be self sufficient and even contribute to the energy grid. When installed on a sunny roof, solar panels can generate electricity for years and can be prove to be a smart investment for homeowners.
