"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

DIY solar panel installations are hard to manage by yourself. You’ll likely need some help or prior experience to make the project worth the effort.

There are a few great questions to ask a solar contractor or inspector when you speak to them. You’ll probably want to find out about the energy yield and efficiency of your array, ensuring the actual output matches the amount you calculated when installing the array in the first place. It’s also a good idea to find out about any damage or wear and tear on the array and to inquire about how soon you need to make repairs or replacements to essential components.

The average homeowner needs around 22 solar panels, but the exact number depends on your monthly energy consumption. Your solar professional should size your array to offset your consumption, meaning you’ll need fewer panels if you use below-average amounts of electricity, or more than 22 if you use above-average amounts of electricity. The number of panels also depends on the output of each panel. The average is around 400 watts, but you might need more panels if you install less capable equipment. Since there are so many variables, you should have a professional size your system.

Solar panels can pay for themselves in five to 15 years, depending on the cost of your system, how much energy it generates, whether you qualify for incentives or power buybacks, and the price of energy in your area. Solar panels pay for themselves over time as they lower electricity bills, so it will take time to recoup your initial investment. However, the longer you have your system, the more money you can save and earn.

A few disadvantages of installing solar panels on your roof include the high up-front costs and the potential for increased property taxes. Installing solar panels can increase the home’s value, which in turn can mean higher taxes. Depending on your area, you should check with your local tax offices for more information. Another potential pitfall is roof leaks from a poor installation, but this shouldn’t be an issue if you hire a reputable company.
