"Had an old fixture above kitchen sink go kaput (fluorescent starter disintegrated), so Cardinal came out and offered LED alternatives (two provided, brought on-hand from supply warehouse). Also fixed a switched outlet that had shorted out. Great work done, nice alternatives for the LED light, and switched outlet was wired to be always-on for one socket and switched for the other -- better than it was before at no additional cost. Later I called to ask the exact serial and model number of the LED light because the papers left did not state it. Not only did I get an email a couple hours later with the model/serial, the tech included the detailed documentation for the fixture so if anything goes wrong I can likely fix it myself next time. The tech who did the work also applied a 10% off discount card for me with no extra hassle, saving me close to $100 on the work."

Drews Solar is a one-man business, where each project receives my full attention. I cover all aspects of the business, including site visits, design, installation and customer service. My customers appreciate the ease of working with the same person every step of the way, and I think you’ll feel the same. I show up on time, am easy to contact throughout the process, I set realistic expectations with customers, and never cut corners with my work. I treat each home like it were my own – my installations are clean and sleek, and I choose quality equipment that is highly-reliable and looks good on your home.

"Mike and Maria Drews promptly and informatively answered the many questions we emailed them. Mike came to our home in order to prepare a formal bid, and he spent about 45 minutes assessing every aspect of the roof, house, garage, basement, electrical panel, internet, asking loads of questions to ensure he knew what we wanted. Drews started the installation right on schedule, and it went as smoothly as any home project we’ve ever had done. Mike and Maria were in regular communication with us all the way through, answering questions and offering explanations, and they went out of their way to make sure we felt heard and got the answers we needed. The crew was prompt, courteous and very, very competent. They did a stellar job of the installation, got all the required city inspections done, got the MG&E sign-off on the installation, and did a truly superior job of cleaning up the job site each day. Drews Solar is simply the best there is - local, competent, ethical and terrific!"

Solar Panels questions, 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.

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.

For most U.S. homeowners, switching to solar energy is an excellent investment. A properly sized solar array can significantly reduce your electric bill, saving money on utilities every month. Most homeowners enjoy savings that cover the cost of their solar systems within 12 years and then turn a profit. Additionally, federal and state tax incentives are available that help make solar an even better and more profitable investment.

Rooftop solar panels supply energy to a single household, where a solar farm can power multiple homes at once with clean energy. Residential rooftop solar panels cost more per watt with a lower project total, and those panels only service the residence they are installed on (in most circumstances). With a solar farm, multiple households can buy into the project and share the overall cost.

It’s possible that installing solar panels can lead to mold on the roof. The panels themselves are not the issue. Problems caused by improper installation—such as roof leaks and mounts that aren’t sealed properly—can cause mold. Another potential cause of mold is debris accumulation under panels, which can trap moisture. If you live somewhere with extreme snow, rain, or hail, your home could be more prone to mold.
