South Miami Approves Solar Roof Rules, Inspired by a Teenager – Reynolds had already devoted years to raising awareness about climate change and sea level rise before starting her campaign for solar ordinances. She founded a nonprofit called The Sink or Swim Project, which highlights the climate challenges facing South Florida. Show this to your kids – motivate them. They’re the ones who inherit our world.

Analysis: Ratepayers foot the bill for utilities’ push against rooftop solar – We’ve talked about it here before, but I just wanted to remind you – when the electricity utilities pay politicians to change legislation in their favor – they’re using your money. You fund the war against you.
SolarEdge HD Wave – The link here is back to an article we published in February, and this PR has this new description – Single-phase HD-Wave inverter, the new three-phase E-Series inverter which is smaller, lighter, quieter, and more efficient than the previous generation, and a new compact residential solution for 4-8 panels. Mentioning it because of the South Miami solar mandate above – its the smallest inverter I’ve seen, and its perfect if you’re building a system meeting minimum code requirements. Plus, in my opinion, it being solid state is part of the future of the industry.
JinkoSolar starts perovskite cell R&D collaboration – When a corporate entity steps into research, generally, the probability of that product being used within a relatively short time frame is much higher. This is definitely still a research project – but it is one of the largest solar panel manufacturers in the world. Last year, Trina Solar started perovskite research as well. I think this technology becomes real.
LONGi first customer of Meyer Burger’s ‘MAiA EVO’ PERC solar cell tool – The integration of both front side anti-reflection coating and rear side passivation coating into a single processing platform for PERC cells is designed to reduce the complexity of production and lower operating costs. Tool(s) manufacturing footprint is also claimed to be reduced. Next generation technologies are slowly moving into production lines.
Hawaii Utility’s 100% Renewable Energy Plan Gets the Green Light – This is a headline because it took three plan submissions from the power utilities to get approval, and there are still some questions from the public service commission. For instance – the utilities have, of course, aimed their plan at large scale energy developments versus consumer level.
Elon Musk reminds us how little land it would take to power the USA with solar – “If you wanted to power the entire United States with solar panels, it would take a fairly small corner of Nevada/Texas/Utah. You only need about 100 miles by 100 miles to power the entire United States. And the batteries you need to store that energy to make sure you have 24/7 power is 1 mile by 1 mile.” Since the USA is now 2% powered by solar as of right now, you can shrink that square but remember resistance*distance means you can’t build it all in the desert, it has to be near the people using the energy.
NRG Renewables Unit Lures Suitors as Singer Urges Savings – The nations largest independent power producer recently decided to shed a lot of assets. Its stock price shot up – and this is the reaction from one New York analyst, “The fact that its renewable assets are the most attractive, liquid piece of its portfolio speaks for itself,” said Nathan Serota.
