This solar array expands itself at the right temperature

Wouldn’t it be nice to have a solar panel that’s only there when the sun shines on it? That’s the idea behind this research project, which uses shape-shifting materials to make a solar panel grow from a compressed state to an expanded one with nothing more than a change in temperature. The flower-like prototype device […]

Aurora Solar’s computer-generated installation maps pull in a $20M Series A

Solar installations are becoming a no-brainer for anyone with a roof in much of the country. But getting an estimate on how much it would cost and how much juice it would generate can be complicated and time consuming. Aurora Solar has made an automated process for doing this, and attracted $20 million in funding […]

This project is mapping every solar panel in the country using machine learning

Renewable energy is the future, but at present no one is tracking just who’s got solar panels on their roof, in their back yard, or a shared neighborhood installation. Fortunately, solar panels generally work best when exposed to the light. That makes them easy to spot, and count, from orbit — which is just what […]

The Sun Exchange wants to change that by leveraging the hearts and wallets of hobby investors, who cover the installation costs and then have their share of the revenue trickle […]
