PERC cells at 20% efficiency leading towards 330W 72 cell modules from Suntech that are 5% more efficient – If you get 5% more energy out of a solar panel and everything else costs exactly the same – then your solar power system just got ~5% cheaper. These ‘small’ technological moves have significant pricing effects when you consider the broader supply chain and construction requirements.
Solar power and batteries being installed in New York City to defend against natural disasters – Strategically distributing solar panels and batteries in an ultra dense city can defend against large scale grid collapses. And New York City, after realizing that climate change can affect it so significantly when Hurricane Sandy hit, has decided to deploy. Certain projects that I’ve worked on in the city get an extra payment from the power company for installing areas that need the distributed energy. Cool to see a city planning on levels like this.
