I read the Great British Energy strategy paper this week — what a disaster. It’s big, top-down, 20th-century, communist-era thinking on energy. Whenever a government says it wants to “shape markets” and “respond to market failures”, allow me to translate: “subsidise uneconomic energy with taxpayers’ money” and “waste billions we don’t have”. Solar and storage are already the lowest-cost solutions, but stupid bureaucracy is holding them back. The UK should focus on bottom-up

How to solve 80% of climate: just digitise the grid and let solar fly! I love the global village that is COP, especially in the polarised, war-mongering world we’re now in. Honestly, it is quite beautiful mingling with all the cultures and peoples of humanity, together physically in one venue – I met scores of amazing, caring people – it’s an environmentalist’s mecca and a beacon of hope for multilateralism. I felt really proud to be a sponsor of the Global Solar Council’s 10

From an inspiring visit to India with 70% solar growth and an ambitious 10m rooftop program, to a week in Australia - another solar star country!  We’re seeing huge growth in battery adoption to add to the 35% solar penetration. Aussie pros have installed 2GWh of distributed battery installs in just the first 4 months of the new battery initiative! The market feels a little scarily hot right now so watch out everyone (I’d prefer a market-driven policy to de-risk this) but the

We’ve recently completed a $20 million equity raise from leading technology investors including Titanium Ventures, Google, and 2150 Sustainability Fund, among others, who share our belief that clean-energy progress comes from empowering the people who deliver it.

The resi solar industry in the US stands at a crossroads.   We either accept the one side: complexity, shrinking incentives, fading net metering and falling demand.  Or the other: affordable, reliable, incentive-free  clean energy for every home. US residential solar today costs an average of $5.18/W, with storage. But it doesn't have to remain that way! At $5.18/W, US customers are paying more for solar electricity, and so without the ITC and with fading net metering, demand

Heat is officially a frontline equity issue. And this is where solar comes in, not just as a clean energy source, but as literal cooling infrastructure.

Back in 2019, we had this crazy idea: what if we gave away the world’s best solar design software…for free? No catch. No upsell. No subscription plan lurking behind a 14-day trial. Just pure, open access to solar software that actually worked. We believed that solar pros deserved better than clunky desktop relics and overpriced platforms. Since then, more than 25,000 installers across 160+ countries have joined us. They’ve used OpenSolar to sell smarter, move faster, and buil
