Get a quoteFor homeowners, these global cost trends translate into more affordable rooftop solar installations. As utility-scale solar prices fall, residential systems also benefit from cheaper panels, lower installation costs, and more competitive financing.
Today’s premium monocrystalline solar panels typically cost between 30 and 50 cents per Watt, putting the price of a single 400-watt solar panel between $120 to $200, depending on how you buy it. Less efficient polycrystalline panels are typically cheaper at $0.25 per Watt. The cost of a solar panel also depends on how you buy it.
A good price per watt for rooftop solar provides a balance of savings potential and robust warranty and service coverage. Based on recent solar pricing trends from the SEIA, this balance can be found in the $3-4 per watt range for residential solar projects.
Furthermore, while most rooftop solar panel systems are eligible to be covered by a standard homeowner insurance policy, homeowners will most likely need to boost the amount of coverage they put on their homes due to the increased cost that comes with the solar panel system.
As the cost of solar panels and solar shingles continues to decrease, millions of homeowners across the country might be considering investing in rooftop solar arrays to provide their own electricity. First and foremost, it is worth noting that around 43 percent of all households in the United States rent the homes they live in.
The cost of a Tesla solar roof depends on the size of the system you need. For an 8.5kW system, you might only need a 7kW system with a 3 IN 1 ROOF. A 3 IN 1 ROOF is expected to cost about $27.00-$28.00 per square foot installed.
