One of the reasons why mass deployment of solar power still remains a distant goal is that most solar panels use lithium-ion batteries, which are expensive, harmful to the environment, and come with the added risk of fires and explosions due to overheating.

For the first time, a safer, cheaper, and more durable alternative to lithium ion batteries has been developed in the form of zinc energy based storage systems.

California’s new rules requiring solar panels on almost all new homes will likely benefit solar installation and manufacturing companies, but may have a nuanced effect on energy markets more broadly.

A momentous leap in green energy was made today as the California Energy Commission voted on a bill requiring all new homes to have solar, starting by 2020. This news is startling to say the least and to put things into perspective—California just became the first and only state to mandate rooftop solar panels on new home construction.

Imagine you spend about $10,000 for a 3-kW solar photovoltaic (PV) system – the size needed for an average family – and your neighbor to the east adds a second story to his garage.

The addition is designed for offspring who will perhaps never leave home, but it shades your new solar panels. It’s not too bad in summer, but in winter it blocks all but an hour of late morning sun. You would have been better off taking that two-week vacation in Jamaica or Cabo San Lucas.

Three national nonprofit organizations recently partnered to create an online resource that examines solar industry programs and policies as they relate to low-income American families.

The three nonprofits — the New York-based Center for Social Inclusion, California-based GRID Alternatives and California-based Vote Solar — launched the “Low-Income Solar Policy Guide” on March 14 during an event in Manhattan.

The sun will continue to shine on the solar industry in California. Utility regulators there voted this week to retain retail rate net metering for solar customers. While there will be some changes to the state’s net metering policies, the vote is seen by most as a victory for California’s rooftop solar customers and businesses.

The world’s most innovative, livable, energy efficient homes of the future are on display in the Orange County Great Park in Irvine, Calif. this week.

Could the utility war on solar be so catastrophically timed as to spur mass grid defection?

If California utilities had proposed slashing net metering benefits in half and tacking on an $18 monthly connection fee for solar customers three years ago, it might have stifled the growing industry. Instead, the proposal to the California regulators is timed to coincide with the release of the Tesla Powerwall.
