We work with people looking to make the switch to renewable power for their home or incorporate renewables into their business model. SunFlower is enabling homeowners, local businesses and agricultural producers to implement sustainable energy into their lives and operations through a number of local, state and federal incentives. The federal government is currently offering a 30% tax credit for renewable energy installations called the Investment Tax Credit (ITC), which is applicable to all solar project costs.

"Great company"

Solar Panels questions, answered by experts

You can start narrowing your search for a reputable solar company by finding local, regional, and national companies that service your area and maintain positive reviews online. You should also check the Better Business Bureau’s (BBB) website to see if the company has complaints filed against them. Next, contact the remaining candidates and ask about installation timelines, warranty coverage, and financing options. Choose a company that offers a labor warranty that lasts at least 10 years and prioritizes cash purchases and solar loans.

Yes, you can connect an inverter directly to your solar panels without solar battery storage if your home is connected to the power grid. However, most pros don’t recommend a direct connection because solar panels don’t put out steady voltage. It’s always best to install a charge controller between your solar panel and your inverter to regulate the flow of energy and ensure a stable power supply.

You can install solar panels on a flat or pitched roof, but keep in mind that they will need to rest at a 30- to 50-degree tilt for optimal sun absorption. It costs more to install solar panels on a flat roof because you will need to install a framing system and likely hire a structural engineer. If your roof has a pitch of more than 40 degrees, it may not be a good candidate for solar panels.

The average cost to install solar panels is around $26,600, and most homeowners pay between $4,500 and $53,000. Keep in mind that these prices don’t consider the federal investment tax credit (ITC), which can effectively reduce those costs by up to 30%. The price you can expect to pay for solar panel installation depends on the size of the system, where you live, the type and brand of panels, and the labor costs. Get price quotes from at least three solar companies in your area to find the best deal.

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.
