Solar O&M comes down to mechanical rooftop connections, electrical solar panel connections, panel and connection temperatures, and inverters. Here are four possible plans of attack.

Kent Kernahan set out to take the heat out of solar cells. He and his partners may end up bringing solar manufacturing jobs to disadvantaged communities and making low-cost rooftop solar widely available.

Also on the rise: Canadian Solar wins a big energy storage bid, report makes a case for lots more rooftop solar in California, and Babcock & Wilcox will market a 100-hour, 135 MW energy storage technology.

Also on the rise: Jinko Solar and Maersk agree to work to ease shipping bottlenecks; and House and Senate bills target interstate rights-of-way for clean energy development, EV charging, and high-speed internet.

Rooftop solar is just the start, as energy storage, smart electrical panels, and EV chargers enter the mainstream for solar owners. Here’s a guide to matching your solar array with some of the most popular accessories.

By combining hardware and software platforms, the two aim to create ‘zero energy homes,’ where energy is produced and used optimally on-site.

Also on the rise: A big solar + storage project in New Mexico secures construction financing, and racking and tracker company OMCO Solar offers a business update.

The fee-based SolarAPP+ is designed to enable solar companies to cut time-to-install through an automated permitting process that may be used in more than 1,200 jurisdictions across more than 20 states.

Too big? Too small? Just right? Many factors need to be considered when deciding how large or small to make your rooftop solar array. Here are our pro tips.

Regulators are set to discuss the cap, though it is unclear whether that means to raise it, or implement a successor program.
