While the hot summer sun pulls you back into the shade and sleeps on the SPF, you can put the intense rays to work to provide clean energy for your home.
The solar panels you see today are leaps ahead of those installed at the end of solar energy. It is no longer futuristic or reserved for the highest end houses. The US Energy Information Administration says that 3% of the nation’s power comes from the sun, and they expect it to reach 14% by 2035. Solar energy is accessible, and you can install it right away. Here’s what you need to know.
Your energy needs determine the size and cost of your solar panel installation. You can install a system that handles all your electrical needs and then some, or you can go for a smaller and less expensive array that will partially cover your energy drain and hang on to the mains for the rest.
According to the US Energy Information Administration, the average house uses about 893 kilowatt-hours (kWh) per month, or 30 kWh per day. Check your electric bill for your exact number, as you will need it when talking to your professional installer.
A small system that generates about 5 kilowatts can ease the energy drain on your power system and your wallet by providing at least half of the energy you need. It will cost between $ 12,500 and $ 17,500. A 10-kilowatt installation generates enough power for the average home. It usually costs between $ 25,000 and $ 35,000 and takes up a significant amount of space on your roof. While it may seem like a significant investment, solar energy could potentially save you up to $ 20,000 over 20 years. In many cases, the systems pay for themselves.
What Happens to Excess Energy Here’s a big bonus of solar energy: Your home is still connected to the entire power grid in most areas. When you generate more electricity than you use, it delivers energy back into the system. This often results in a credit on your electricity bill, known as “network metering”. Fun fact: You can see how your meter is running backwards when this happens.
Non-metering not only lowers your bills, but helps your neighbors by easing the load on the power grid. When everyone has their ACs running at max, each house takes that energy back and the grid delivers the area one step back from a potential blackout.
What to Ask Contractors Solar energy contracts need to juggle many factors while you want to install your panels, including your local area network, specific energy needs, and the available sunlight around your home. This is a big job, so ask for different offers and compare them. Here are some questions to ask when choosing.
• How would you rate my system, and what factors would you consider?
• What guarantee do you offer? (Between five and 10 years is a typical industry standard.)
• Will you personally inspect my roof before making an offer?
• How many installations did you make?
Tax benefits Solar panels can pay for themselves by returning more than just energy. Plus, you can apply for a Federal Investment Tax Credit (ITC) if you install residential solar. And it’s a generous credit – if you get the job done on time. Here’s a look at what you can ask for.
• Systems installed 2022: 26%
• Systems installed in 2023: 22%
• 2024 and later: Credit runs
In many cases, you can also request benefits or incentives from your state or city council, as well as utility companies. Your Solar Pro should be able to tell you all the options available.
