![]() That Solar Roof estimate breaks down to $176,600 for the solar part of the roof and $29,600 for tearing off the old roof. Steep pitches, multiple levels and a lot of obstructions could drive up the cost. Tesla estimates 12 kilowatts of regular solar panels and a Powerwall at the same location will cost $26,966.Īnother factor that could alter the price of your system is the complexity of your roof. Tesla's online estimate for a house in Dallas offered 12.46 kilowatts of solar generation and a Powerwall battery for $168,400. ![]() Contact us today to learn more about ground-mounted solar and rooftop PV panels.If your goal is to generate solar for the least amount of money possible, a Solar Roof isn't for you. Homeowners throughout Utah, Idaho, Colorado, Wyoming and Nevada can schedule a free consultation with Intermountain Wind & Solar, the region’s leading photovoltaic installer. A professional contractor can help you weigh the benefits and drawbacks of each option and offer recommendations for the most cost-effective installation. Ultimately, the best decision for your photovoltaic array will depend on several factors - not just your out-of-pocket expenses. ![]() A photovoltaic array mounted at ground level can be placed at the optimal orientation and angle for maximum energy production. Under these conditions, rooftop solar panels may not be as effective as a ground-mounted solar installation. ![]() Others are shaded by obstructions, such as nearby buildings and trees, or are too small to hold more than a few photovoltaic modules. Some rooftops face the wrong direction for capturing the sun’s energy. However, cost isn’t the only consideration. If your roof is in good shape or needs only minor repairs, you can save money by choosing to install rooftop solar panels. Which Type of Photovoltaic Installation Is Right for You? If your roof develops a leak or related problem, the panel array must be removed to fix the problem and subsequently reinstalled.Īs this is an expensive, time-consuming and complicated process, professional photovoltaic contractors recommend repairing or replacing a damaged roof before scheduling a rooftop installation. The modules are designed to last for decades, and placing them on a damaged roof is never a good plan. Photovoltaic panels must be mounted on a solid, stable structure. However, rooftop installation has one potential added cost - roof repair or replacement. Plus, the mounting components are much less expensive. Rooftop solar panels are faster and easier to install than a ground-based solar energy system, so labor charges are minimal. To prevent critters from munching on your wires, you may need to bury them.ĭigging trenches for underground wiring is an extra cost you won’t have with a rooftop array. In addition, placing a photovoltaic array at ground level puts the wiring components in easy reach of rabbits, squirrels and other backyard pests. Labor charges are also higher for ground-mounted panels, due to the more involved mounting process. The additional materials needed - including reinforced pole structures and cement foundations - are responsible for much of the added expense. Ground-mounted photovoltaic arrays typically cost more than rooftop systems. So which type of photovoltaic array is more affordable? But if you’re like most homeowners, cost will factor into your decision. Both ground-mounted and rooftop solar panels offer unique benefits, and both provide you with a free source of electricity for your home.
