“I’ve begun worshipping the sun for a number of reasons. First of all, unlike some other gods I could mention, I can see the sun. It’s there for me every day. And the things it brings me are quite apparent all the time: heat, light, food, and a lovely day. There’s no mystery, no one asks for money, I don’t have to dress up, and there’s no boring pageantry.” ― George Carlin, Brain DroppingsIn the last ten years, installation of rooftop solar power generation systems have been picking up steam, mainly due to fall in prices of solar panels. Solar panel prices have dropped from ten dollars per watt a decade ago to less than a dollar per watt. Even then, with out subsidy, the return on investment (ROI) for rooftop solar installation takes more than eight years. The economics can be improved if cheap battery storage is incorporated, i.e. energy generated during the day is stored for later use such as during the night. So far cheap battery storage has been elusive, but things are about to change for the better. Lithium-ion batteries for storage, which do not have any of the drawbacks of lead acid batteries, are getting cheaper because people are seeing the benefits of owning an electric vehicle (EV). Nearly all EVs use Lithium-ion batteries to store energy, which is used to propel and operate the vehicle. The question is why would someone be interested in getting an EV when internal combustion engine (ICE) vehicle that uses petrol is so widely available. “If the costs are the same, then there is no question an EV is superior in every way to an ICE vehicle,” said P Venkat who camped overnight to put deposits for two Model 3 Tesla electric cars with a base price of $35,000 on March 31, 2016; about 18 months before delivery. The excitement was so palpable at Model 3 launch that Tesla received deposits for over 300,000 cars in a matter of days. “Compared to an ICE car, an electric car drives like a sports car but is quiet, has drastically low maintenance, is safer, emits zero toxic gases, and you start the day with full range,” added P Venkatesh. Seeing the rush in demand for EVs, over the next few years, nearly 20 new electric cars and SUVs will be launched by major car companies worldwide. India’s Mahindra already has the e2o (previously called REVA) on the market and Tata’s subsidiary in UK (Jaguar LandRover Ltd) is slated to release an all electric SUV in 2018
