"I spoke with the owner George on the phone about possibly only an install of solar panels not buying product through his company. He spent the time to explain the process and concerns he could see with my plan. Based on his willingness to spend ample time explaining the process I ended up using his company for the complete project. I am more than satisfied with the end result. The company did not sell me unneeded equipment and kept me informed throughout the whole process. They completed all the necessary paperwork for the state which included the $1000 rebate from the state of New Hampshire. Quality workmanship and great customer service. I would absolutely recommend this company for any person considering going solar!"

"Millhouse Enterprises was great with assisting us with style, selection and cost control when inquiring about fencing. They were quick with a quote and installation of our fence. Customer service was top rate. They were always available for quesitons and did not pressure us to make a decision. I would recommend them again and again. As a matter of fact they are working on another quote for us today."

"Professional, responsive, and efficient. Sunup Solar designed and installed our off-grid system during late winter and fit into our time crunch to move into our new home. We are ecstatic to show photos and tell others how an off-grid lifestyle can be modern, and in our case, even within sight of on-grid neighbors. During the hottest days we run AC without worrying about a power bill, and when a summer storm hits our lights never go out. Our home has become an example for countless family and friends to consider building off-grid, and we continue to recommend Sunup Solar to folks across New England. Thank you Hunter and your team for powering our dream home."

Solar Panels questions, answered by experts

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.

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 batteries can be a great investment to help maximize your solar savings and make your system and home more valuable, but they’re most beneficial to customers who don’t have access to net metering. If your state or energy provider doesn’t provide net metering, batteries can be a great way to offset consumption even when your panels aren’t producing power. They also come with the added benefit of providing electricity through blackouts, so they’re valuable in areas prone to severe weather that could cause frequent blackouts. Your installer can help you decide if batteries are worthwhile.

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, it is possible to install solar panels on a tar and gravel roof, but it is not the ideal roofing material for a solar installation. The process requires roof penetrations to install the solar racking system. While installers will seal these penetrations, they still increase the risk of leaks. This risk is higher on tar and gravel roofs, which are often flat. Flat roofs are more prone to leaks than sloped roofs because they can pool water during heavy rain and hold snow for longer periods, exposing the roof to more moisture.
