Since the factory announced Gigafactory project, Tesla has claimed that the factory will not use any fossil fuel, but the use of renewable energy to replace fossil fuels, mainly rely on the solar array to provide energy. Now, the company has confirmed that Gigafactory will have rooftop solar arrays and ground solar facilities. Tesla to provide investors with the introduction of the material, said the 70MW can provide a rooftop solar array will become the world's largest solar power generation facilities.
Truss said the first Gigafactory will be a factory without the use of fossil fuels (gas or oil) completely rely on manufacturing plant power. Through the combination of a 70MW rooftop solar array and solar ground facilities, we will use 100% of sustainable energy. The new rooftop solar array system, which is more than 7 times the size of the world's largest solar array, has been put into use
At present, the largest rooftop solar array has been put into use in the United States, from the California state Whirlpool Corp (Whirlpool Corporation) of the Perris regional distribution center, its capacity is 10MW. The other larger solar array comes from India, which has a capacity of 11.5MW. The sum of 70MW truss capacity will be more than this two.
Tesla explains how to successfully reduce the cost of investment in each GWh unit of Gigafactory plant and how to achieve growth:
1, improve the production facilities of production density, speed up production capacity;
2, interior design and construction methods;
3, complete and comprehensive facilities system, equipment design, layout and implementation methods;
4, innovative construction technology can effectively reduce the occupation of land, buildings and infrastructure area, as well as construction materials and labor costs.
For each kWh battery and battery production costs are reduced, Tesla also gives the following measures:
1, to co-ordinate arrangements for production, to reduce the amount of tax and investment costs (raw materials, components, labor, energy and water);
2, re engineering the design of all the supply chain, to achieve a more efficient production capacity and the need for customized components, but also to reduce transportation costs;
3, improve the design of battery products, improve the level of energy density of batteries, optimize the size of the battery (2170 vs);
4, improve the battery module and battery design content, improve the battery energy density level;
5. Improve automation and process design to improve production. Reduce the cost and improve the reliability of the waste;
6, reduce the capital investment per GWh capacity, reduce depreciation costs.more solar batteries like:
