Tesla uses durable roofing materials, including steel roofing tiles.

However, compensation rates vary by state and do not always equal the full electricity rate. In states with net metering policies, electricity companies purchase surplus energy generated by solar power systems, giving you a power bill credit in return. Solar roofs and traditional panels offer a higher return on investment (ROI) when your installer sizes your system according to your home’s energy needs. For example, California has an average electricity price of 27.15 cents per kWh, so 9,000 kWh of solar generation could save over $2,440 in annual electricity bills. The exact savings achieved by a solar roof vary depending on local sunshine conditions and electricity prices. At this price, 9,000 kWh of solar generation can save you over $1,420 on energy bills per year.Energy Information Administration, homeowners pay an average electric tariff of 15.85 cents per kWh. This means a 6 kW solar roof can generate over 9,000 kWh of energy each year. With favorable sunshine conditions, each kilowatt of solar capacity can yield over 1,500 kWh per year.Like a traditional PV system, a Tesla solar roof reduces your monthly energy bills over the system’s 25-year life expectancy. These prices apply if you purchase a battery directly from Tesla, but can increase to around $11,500 with added installation.A Tesla Powerwall costs around $9,200 without installation, and the price increases to $18,400 if you purchase two units.While installing a battery can save you money on electricity in the long run, it adds to your total system cost. Both Tesla solar shingles and panels are compatible with the Powerwall battery, which has an energy storage capacity of 13.5 kilowatt-hours (kWh). Your total cost will also depend on your system components. While some solar companies offer roofing services, you will likely have to work with separate companies if you need a roof replacement with regular panels, and the PV system may negatively impact the roof warranty. If you choose a Tesla roof, you will work with a single provider that offers a 25-year warranty. In this case, a Tesla roof of the same wattage is only slightly more expensive at $38,400. It can cost between $8,500 and $15,000 to replace a 2,000-square-foot roof, meaning your total cost could reach upwards of $35,000 with a 6 kW solar system. But the cost may be comparable if you need a new roof with your solar panel installation. Tesla began selling solar panels in 2016 after Elon Musk acquired SolarCity and reorganized the company into Tesla’s energy division.Īs you can see, installing a solar system with traditional panels is cheaper than a solar roof. Tesla has a price-match guarantee, which means the company will match competing solar offers of similar quality. Tesla also makes solar panels if you don’t need to replace your current roof and prefer a more traditional system.


For example, the national average cost of a solar energy system is $2.85 per watt, so a 6 kW system would cost $17,094 before incentives. The main factor that determines the cost of a solar system with traditional panels is the installed capacity, measured in kilowatts (kW).
