Weddle & Sons, a certified solar roof installer for Kansas, Colorado, Nebraska, some areas in Missouri, Iowa, and Oklahoma, posted a new video on YouTube showing how a Tesla solar roof was installed in a single day. They traveled to Loveland, Colorado to install a 30-square-foot roof with a 12-kW PV system. Note, however: you started tearing down the original roof and underlay a week earlier to facilitate the required inspection of the center roof.
The crew consisted of 8 roof installers and 3 ground supporters for the project. They also had visitors on site all day to watch the progress. While the company didn’t split the price for this Tesla solar roof installation due to privacy concerns, there is a price estimate on their website for anyone who wants one.
A quick look at the price calculator shows that with a roof size of 30 square feet and a system size of 12 kW, a Tesla solar roof starts at $ 36,300 before any incentives. It is not known if this came with a powerwall or not so I left that out. While this is only an estimate, it should be noted that complexity factors such as steepness, dormers, a higher number of facets, irregularly shaped facets, and obstacles such as skylights can all affect the price.
Weddle & Sons is Tesla certified to install its solar roof system. The company even traveled to Tesla’s California facility for hands-on experience with its solar roof and is the only certified plumber in the Midwest.
Solar 2021 forecasts
According to the US Energy Information Administration (EIA), wind and sun could make up 70% of the new US generation in 2021. The battery storage capacity will also quadruple in the next year.
The EIA also noted that its most recent inventory of generators, developers and power plant owners plans to add 39.7 gigawatts of new electricity generation capacity to begin commercial operations in 2021. Solar will account for the largest share of this new capacity at 39%. The wind is next at 31%, and 3% will come from the new nuclear reactor at the Vogtle power plant in Georgia – assuming it goes online.
The EIA assumes that the capacity of the battery storage system “will more than quadruple” on a supply scale. 4.3 gigawatts of battery capacity are to be added by the end of 2021. Since battery storage systems are often combined with renewable energy sources, the EIA found that the rapid growth of renewable energies such as solar energy is making a significant contribution to the expansion of battery capacity.
The world’s largest solar-powered battery (409 megawatts / 900 megawatt hours) is being built in the Manatee Solar Energy Center in Florida and is expected to be in operation by the end of 2021. It is certain that 2021 will be the year for solar and renewable energy.
