Tesla Powerwall – solving the battery problem – once and for all.
When Elon Musk went about setting up a battery manufacturing plant called Gigafactory people thought that he was building battery plant for the cars that his company would be manufacturing. People thought he would be selling about 10,000 Tesla cars a year at the maximum as they wre quite expensive. But Elon being Elon was out thinking everybody and leaping ahead into building the fuel-storage-blocks of tomorrow.
He will be building batteries not only for cars but also every damn thing that consumes power – from things like street lights, home power banks, community power banks, factory power banks, for schools, for markets, shopping malls etc. His customers could include rival car manufacturing companies, Power plants, Solar/Wind home users, Malls, Multiplexes, Schools, on-grid and off-grid Communities, etc. These places could use multiple type of paid or free-clean energy to charge these power-banks. Even for cars/buses/trucks if customers want to change to a new set of battery perhaps people could switch over to the Tesla powerwall.
What is Tesla Powerwall?
The Tesla Powerwall is a big home battery made of lithium-ion and charges on solar energy. The batteries come in two variants, costing $3500 and $3,000, and are capable of storing 10 kwh and 7 kwh of energy respectively. To put this in perspective, a 1-kilowatt heater can run for ten hours with 10kWh of energy. These batteries are housed in a well-designed package and you can hang them on a wall. It’s about 4 feet by 7 feet and has a width of eries are housed in a well-designed package and you can hang them on a wall. It’s about 4 feet by 7 feet and has a width of about 7 inches. The price, is also a third of such batteries available in the market.
What problem does it solve?
The batteries are primed for home use, where typically more electricity is consumed during peak hours in the morning and evening. By storing the electricity generated during the day, the peak hour demand can be met with ease. Tesla has also announced a scalable Powerpack which it intends to sell to power utilities and corporations.
Solar power works if panels and batteries are affordable. Cost of panels are already falling, thanks largely to China. If battery prices are also on the way down, one can expect a lot of action in the domain. India has an ambitious solar energy plan, which will generate huge orders that will lead to economies of scale, helping solar energy reach ‘grid parity’ or the point where it costs the same as thermal power.
Powerwall begins shipping this summer and requires installation by a trained electrician. Reserve yours today and you’ll be contacted this summer to arrange installation.
Powerwall comes in 10 kWh weekly cycle and 7 kWh daily cycle models. Both are guaranteed for ten years and are sufficient to power most homes during peak evening hours. Multiple batteries may be installed together for homes with greater energy need, up to 90 kWh total for the 10 kWh battery and 63 kWh total for the 7 kWh battery.
Can it be a game changer for India?
If successful, the battery will be a game changer in India’s standby power sector, which burns diesel. Diesel generators add up to an estimated 60,000 mw, or the combined capacity of 15 ultra mega power plants. These are essential for malls, telecom towers, hospitals etc because a power cut can cripple operations. For residential areas, reliable low-cost storage can help consumers get off the grid, as is already happening in some Western countries. In far-flung areas, such batteries will support setting up of microgrids in hamlets. In hilly areas, where one needs light more than fans, such technology, along with use of energy-efficient LED bulbs can power homes at a small cost.
The Tesla Powerwall opens up a huge range of opportunities. Earlier battery purchasing was a big headache. The good sources or companies were limited and the quality depended upon the source. It would be less headache for Solar Panel manufacturers and installers if they were sure about the quality of battery they use. Home solar installers were always quite unsure whether or not to invest a huge amount of money in a battery, the quality of which, they were not sure about but with Elon Musk’s name and quality behind the brand Tesla Powerwall might end up in every home, office and car.
This Battery capacity is sufficient for running off grid solar power homes without using Refregitor or Airconditoner see the below blog:
Is there any better clean energy?
There is only one other type of energy that is better than the tesla power-bank Electricity and that is Biogas which can be generated by managing garbage and human toilet output. Since India is made up of a billion people the amount of garbage and shit generated is close to a billion kilos a day now add to this the amount of animal dung. Thus India could generate about a billion kilos of CNG every day. Which could solve the energy problem and clean up the country. The output of biogas is high-grade organic fertilizer in liquid form which can be easily transported or distributed to farmers & gardeners.
This biogas (methane) also called gobar gas when compressed is called CNG. This type of Gas is much safer to use than LPG which is used every day not only for cooking but for running cars and Electricity producing-gen-sets. Even in case of leakage CNG is safer as it disperses into air. If you have CNG leakage in your house you can open the windows and the methane will go outside with the wind. But in case of LPG leak the gas will not go outside but will stay in your room like water. LPG without pressure will only flow and collect downwards Thus CNG gas is safer to use and store.
