The solar energy is our future and Tesla CEO Elon Musk works really hard to make it available to the normal people. Their goal is to make new solar roof tiles as cheap as the shingle roof.
According to the estimation of the International Energy Agency the solar would be the world’s primary source of energy by 2050, and the 2016 data from Bloomberg New Energy Finance (BNEF), showed that solar is the cheapest way to generate energy.
These self-sustainable solar tiles were first introduced in 2017, and the goal of the company was to manufacture them in 2018, however the production is being delayed for two years in a row.
The reason for that Musk claims is their dedication to create a product that it will be affordable and long-lasting, in average it should work for almost 30 years.
This goal is very ambitious, but the engineers in Musk are working on this challenging process. According to the company this is a hard technology as the final product must be good-looking, durable, integrated solar roof tile, lasting for 30 years, and at the same one of the cheapest roofs.
In addition to this, Musk promised to make the charge of this solar roof as same as of a shingle roof. If this would be true, then we would have a new competitive product that for sure will be used by many home building companies. In terms of finances, nowadays a shingle roof can cost as little as $4 per square foot, and a solar tile roof can cost up to $20 per square foot.
The Solar Roof V3
Having an energy-saving solar roof means a lot for one homeowner, namely two years ago the cost of a Tesla Solar Roof was $21.85 per square foot. The new Solar Roof V3 is the advanced version of Tesla Solar Roof and comes with a lifetime of the house warranty and 30-year power generation guaranty. The price is expected to go drastically down becoming even cheaper than a non-solar tile roof of a similar style. Plus, its installation and cost will pay itself in time through electricity savings.
The install time will be reduced with the new solar tiles; at least that is what promised the engineers in Tesla. However, the testing showed that it took again around 2 weeks which is a lot compare to the installation of the tile roof installation, which commonly takes 5 to 7 days.
The advantage of solar power is a limitless supply of energy producing the needed electricity at a substantially lower price. Its development will make energy prices drop so low that anyone could afford it thus getting the electricity from the sun at a substantially lower cost.
There is a progress in this technology, namely the researchers at IBM developed the new High Concentration PhotoVoltaic Thermal (HCPVT) system that runs better than the current conventional solar panels. According to the engineers this system can magnify the sun’s energy by 2000 to 5000 times. In the system are deployed hundred small solar cells that are continuously being cooled in order to generate more energy than regular panels, without wasting the excess.
This project needs funding to be finished and fortunately the Swiss Commission for Technology and Innovation has offered a $2.4 million grant to support its development. The engineers hope that, this technology one day could become a cost-free way to power the world, and because of that they work on it relentlessly and diligently.
