Solar is currently the most promising variety of clean and renewable energy, and is widely used around the world, and even some environmentally friendly buildings will be fully used as the only way to use solar energy. But during the day can use solar energy to power, so how to solve it at night?
As an electric car manufacturer's Tesla, we have given us a conclusion that a solar energy plant called Powerwall is introduced to preserve the energy generated during the day and left for night use. Tesla officially released Powerwall in 2015 and has a whole set of magnificent plans and ideas. And according to a year after the first batch of Powerwall user feedback, Tesla's current plan is quite successful.
Nick Pfitzner is an Australian Powerwall user who installed the system at $ 13,000 at the beginning of 2016, including solar panels, SolarEdge inverters, 7kWh Powerwall, and smart power storage monitoring systems. And this environmentally friendly and loaded solar power supply system has been successful in helping Nick Pfitzner save 92% of its electricity compared to previous years. As most of the ordinary solar power supply system does not include the battery and monitoring system, so Powerwall to the user to bring the efficiency and cost savings have a very significant effect.
With Powerwall, Pfitzner can save excess electricity during the day and will not be used at the same time. The intelligent monitoring system can be based on local climate conditions to predict energy consumption, but also refer to the local public electricity prices. So the system will be automatically in the local electricity when the most expensive, and the lowest in the latter part of the time when the use of public electricity.
Australia is a very high price of the country, but because the local solar energy resources are very rich, so the use of solar energy technology in Australia is very popular. The traditional solar system has a 10 to 15 year investment return period, and after installing Tesla's Powerwall system, the investment return period can be reduced by half. Pfitzner said that in another eight years will be able to complete the investment in Powerwall, and far lower than Tesla before the 14 to 18 years to develop the investment return cycle.
