This change was reportedly made after some homeowners were asked to pay more after signing a contract for a certain purchase cost. Tesla describes these costs as “estimated costs” and has a disclaimer stating that the prices may change based on actual installation and roof removal conditions. Here’s a breakdown of Tesla roof pricing for the home we analyzed: Tesla Roof Cost Factor In this example, roof removal costs $7,700. Tesla also charges for tearing off an existing roof. Without an energy storage system, the roof would cost about $45,200. Along with the recommended Powerwall, this would cost $53,700 after factoring in incentives like the federal tax credit (the system would cost $69,000 without the tax credit). According to Tesla, such a home would require a 6.14 kilowatt (kW) Solar Roof. We evaluated a typical house in California with a 2,000-sqare-foot roof and an average electric bill of $150 per month. This lets homeowners store solar energy for use at night or as backup power during a grid outage. Tesla recommends adding a Powerwall battery to the system as well. Solar shingles generate direct current (DC) power, so a Tesla roof also needs an inverter to turn it into usable alternating current (AC) power for your home. The inactive tiles can be strategically placed in shady spots to maximize the efficiency of the active tiles while maintaining a seamless design. Most homes only need part of their roof to be covered in active tiles to offset their energy bills. They look identical, but the active tiles generate power and the inactive do not. 1 This makes the solar cells almost impossible to spot.Ī Tesla Solar Roof comprises two types of roof tiles - active and inactive. When Tesla got into the solar game and designed its solar roof tiles with subsidiary SolarCity, it integrated solar cells directly into the shingles (initially using a Panasonic cell before parting ways with the company). However, it was an inefficient method with questionable durability.
The first few attempts at BIPV solar roofs were made by pasting flexible solar panels over regular shingles. Source: Tesla How Does the Tesla Solar Roof Work?
Tesla claims its shingles are more durable than traditional roof shingles. These include a 25-year warranty and impressive hail, fire and wind ratings. While there have been other solar shingle products on the market, Tesla’s textured glass tile shingles offer some remarkable advantages. Categorized under Building Integrated Photovoltaics (BIPV), solar roof shingles look much sleeker than traditional solar panels, transforming the aesthetics of a roof equipped with solar. Tesla’s Solar Roof tiles integrate the functionality of solar cells into roof tiles, making it possible for one product to offer two different uses.
