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

The average-sized home in the U.S.—around 2,500 square feet—will require between 15 and 34 solar panels to power the whole home. The specific number, however, will have less to do with home size and more to do with how much energy you use each year and the amount of sunlight in your region.

The time it takes to install solar panels depends on the number of panels and the size of your home, but installation takes between two and three days of work. While most contractors can install the panels over the course of a couple of days, switching to solar energy can take two to three months in total. This includes the time it takes to design the system, procure the parts, obtain the permits, install the panels, connect to the main power grid, and get an inspection.

  • Installing a new electrical meter box

  • Replacing your meter base

  • Replacing your service entrance cable 

The cost to install or upgrade an electrical meter box ranges from $100 to $650, including $50 to $250 for the unit. The meter base passes the power from your electric company to your panel. The cost to replace a meter base is roughly $50 to $250. 

Service entrance cables are electrical cables with multiple wires, bringing power from electrical companies to residential buildings. The cost to replace a service entrance cable ranges roughly from $1,000 to $1,500.

Yes, solar panel installation will require permits. The required permits will depend on where you live, as some states and cities have solar-specific permits, while others only require electrical permits to connect to the grid. In either case, it’s best to hire a reputable solar installer in your area, as a representative should handle all of the necessary permitting for you and will include the cost of the permits in your initial solar estimate.

Correctly installed solar panels will increase the value of your home by around 4%. With the median home sale set at $429,000, this means an increase of approximately $17,000. Many home buyers want to switch to solar, making homes that have this feature tempting and worth the investment compared to homes that are only tied to the grid. Other solar features, like a shed with solar panels, will also boost your home’s value.
