"Exact Solar and the Bortman’s installed solar panels for me on both a previous house and my current house. The panels turned my poolS from the cold poolS that no one wanted to go in, to the fun warm pools all summer with no marginal cost to heat. They did a free solar study from google earth to determine if my house and pool were good candidates for the panels, answered every question and installed them as advertised on time and on budget."

"I contacted Solar Medix replace two DC string inverters on our 15 year old solar array. As it turned out, they were able to correct some wiring instead of replacing the inverters! Thank you for doing a fantastic job! They saved us a few thousand dollars! And I highly recommend them!"

"Dana was professional and very nice. He went above and beyond checking the temperature inside to insure vents were working properly, replacing insulation on tubing and checking thermostats. I would definitely request that he do the work on my heating and air conditioning in the future."

Solar Panels FAQs, answered by experts

Depending on the climate in your area, the best time to install solar panels is either winter or early spring. Summer is a fine time to install panels, too, but it tends to be the busy season, so prices may be higher and companies may have packed schedules. The installation process can take more time than expected between getting permits and finalizing a design, so start as soon as you can.

Yes, going solar really saves money. In fact, according to some calculations, the average homeowner who switches from electric to solar power will save almost $2,000 a year on energy costs. While buying solar panels and switching to solar can be costly up front, the savings add up over time. If you can sell back extra energy or take advantage of tax incentives, your savings can be even higher.

In most cases, yes, solar panels are well worth the investment. Going solar with your home’s energy is expensive, but, in most states, the panels will pay for themselves by reducing your electric bills. Solar panels don’t produce greenhouse gasses or other pollutants, meaning you can feel good about using this renewable energy source to power your home. Plus, installing solar panels can boost your home value, helping your profit off your next home sale.

Solar shingles typically last between 20 and 30 years, a lifespan comparable to that of traditional solar panels and standard asphalt shingles. The exact duration depends on the manufacturer and the quality of the installation. Because solar shingles are a newer technology, there is limited data on their actual long-term performance. Factors that can impact their durability and longevity include weather conditions, roof ventilation, and regular maintenance. To extend the life of your solar shingles, you should conduct regular inspections and cleaning, and make any necessary repairs as quickly as possible.

You shouldn’t hook up a solar panel directly to a battery. That can damage the solar battery and your appliances over time. Instead, install a charge controller between your solar panel and solar battery. Charge controllers regulate voltage, prevent overcharging, and minimize the amount of electrical current to protect your battery from voltage spikes.
