"I selected Home Energy Center based on Angie's List ratings and their coupon for a free diagnostic service call. Steve Cupps was fantastic. He arrived at our home on time and quickly diagnosed two problems. Although he had another service call to make at 5:00 pm, he returned at 7:30 with the required parts (three in all-two from his warehouse and one from an auto parts store) and finished the job. Since the weather was in the 90's every day, we were extremely grateful for his willingness to provide same day, after-hours service. They honored the Angie's List coupon and allowed us to avoid the costly bill of replacing our furnace and AC."

Solar Panels FAQs, answered by experts

Solar panels should get at least four to six hours of direct sunlight daily. It’s even better if sunlight reaches panels between the peak hours of 10 a.m. and 3 p.m. This is enough to power a home, depending on your solar system’s size and energy needs. Remember that panels will generate some power under cloudy skies or in the shade, and many systems compensate for lower sun exposure by drawing energy from the grid or battery storage.

In most cases, installing solar panels will not void your roof warranty. To keep roof warranties intact, check your written warranty or call the manufacturer to ask about clauses regarding roof penetrations. You can also protect yourself by getting written approval or a modified warranty that specifically allows the solar installation type you’re planning. Then, hire a professional solar installer that follows roofing manufacturer instructions and protects the roof during installation.

Yes, solar panel installation will require permits. The required permits will depend on where you live, as some states and cities have solar-specific permits, while others only require electrical permits to connect to the grid. In either case, it’s best to hire a reputable solar installer in your area, as a representative should handle all of the necessary permitting for you and will include the cost of the permits in your initial solar estimate.

While you can install solar panels by yourself, it can be a complicated process full of lots of manual labor, risky roof work, and knowledge of electrical wiring. Most solar panel installation projects should be reserved for a trained professional—especially if you plan on connecting your panels to the electrical grid rather than for off-grid use, which doesn’t require utility services.

Yes, you can connect an inverter directly to your solar panels without solar battery storage if your home is connected to the power grid. However, most pros don’t recommend a direct connection because solar panels don’t put out steady voltage. It’s always best to install a charge controller between your solar panel and your inverter to regulate the flow of energy and ensure a stable power supply.
