Battery Technology Progress To Promote United States Solar Development

- Mar 02, 2015-

In the third quarter of 2014, new generating capacity more than 1/3 across the United States comes from solar panels, including public utilities solar and residential solar panels on the roof. Solar Panel plant growth was the main driver of this trend of grid cells. Solar market now has much larger traditional lithium-ion batteries--that is, mobile phones and laptops are widely used--is cheaper than ever, is also an important impetus for the development of solar energy.

At present, the United States's ambitious goals for solar technology is to put solar panels on the roof, and batteries in the back yard (or basement), is that you finally get rid of dependence on grid, use the free power from the Sun. Solar cells has long been seen as store energy during the day, then at night using one way. But because the price is too high, they have not been able to obtain a wide range of promotion. But many companies as solar and solar cells important in 2015, "tipping point" this assertion is increasingly being used by the media and the industry.

Tesla and Panasonic have been strong cooperation in order to reduce the cost of lithium-ion batteries, large battery factory Gigafactory built by the former, both sides are expected to further lower the cost of lithium-ion batteries by 1/3. According to Navigant Research predicts that Tesla currently need to pay $ 200 per kWh cost for its Panasonic battery, and when their large battery factory--is expected to double production of lithium-ion batteries in the world – in 2020, after the overall operation of the Sierra Nevada, 130, this cost will be reduced to $/kWh. You know a few years ago, lithium-ion batteries also cost as much as $ 1000 per kWh. Tesla plans to produce part of the battery to the power market, SolarCity (an energy company owned by Elon Musk) have also started their own solar panels, energy storage system using Tesla's batteries.

But driving is not just in the development of lithium-ion batteries for solar and solar cells cheaper properties. Other startups have been developing newer, lower cost of battery technology, for example, Aquion Energy and Ambri. Aquion Energy last week announced their largest battery device (2MWh) to be used in solar energy systems on the Kona Coast of Hawaii.
