Series A led by VXI Capital, with backing from the people who built modern solar, including founding Enphase CEO Paul Nahi, former SunPower CEO Tom Werner and former New York energy czar Richard Kauffman Nine years in the making, Optivolt’s energy intelligence turns passive solar hardware into adaptive power systems … [continued]
Volt CEO Peter Leeson and I caught up on Teams this afternoon to discuss the progress of the Volt solar tile. You will have read about his revolutionary product on CleanTechnica here and here. When we last spoke, two years ago, Peter was all set to launch his product on … [continued]
Solar energy is an American success story. Since the creation of the first silicon solar cell 70 years ago, solar leaders have been innovating, improving efficiency, lowering costs, and growing this American-born technology into an essential part of our nation’s energy system. In 2025, solar and storage accounted for 79% … [continued]
Last week, I wrote about the new Jackery EnergyGuard Max 100 kWh battery at IFA Berlin. This large capacity offers customers home energy storage to easily cover their needs as electrification evolves. Those with large, fully electrified homes, solar arrays and multiple EVs would still have capacity left to participate … [continued]
Americans don’t think about grid reliability. They flip the light switch, open the refrigerator, turn up the AC, and expect the power to be there. But as electricity demand surges from data centers, advanced manufacturing, and extreme summer heat, keeping the lights on requires a grid that can deliver power … [continued]
There’s been a push for the past several years to get more cleantech products produced in the United States. One of the key target products is solar panels, as well as the various components of solar panels. That has been encouraged through a variety of strong production incentives (brought into … [continued]
WASHINGTON D.C. — Today the Trump administration is imposing new tariffs and establishing minimum import prices on polysilicon and polysilicon derivative products including ingots, wafer, solar cells, and modules. Following is a statement from Tim Pawlenty, CEO of the Solar Energy Industries Association (SEIA): “America has made terrific progress rebuilding … [continued]
At the 2026 Solar and Energy Storage Innovation Conference, LONGi officially announced that its independently developed crystalline silicon-perovskite tandem solar cell has achieved a conversion efficiency of 35.5%, certified by the European Solar Test Installation (ESTI), once again setting a new world record. Crystalline silicon-perovskite tandem solar cells represent the … [continued]
The Philippines has taken another major step in its clean energy transition with the inauguration of the first phase of the MTerra Solar project, a massive solar and battery storage development that President Ferdinand Marcos Jr. described as proof that the country can deliver world-class energy infrastructure while reducing its … [continued]
I recently had the opportunity to attend InterSolar Europe in Munich, the headlining show of The smarter E Europe. The show was both overwhelming and encouraging. Battery storage is becoming essential to solar power. Balcony solar is extending the benefits of solar and storage to new customers, like people who … [continued]
