The Perovskite Era: Higher Solar Efficiency, Lower Cost
Tandem perovskite-silicon cells have passed 35% efficiency in the lab. Here is what that means for your roof.
Cut through the hype. We track real solar prices, break down new battery and panel technology in plain English, and publish DIY guides so everyday households can actually take advantage of clean, cheaper energy.
New breakthroughs in solar cells and storage, and what they mean for the price you pay.
Tandem perovskite-silicon cells have passed 35% efficiency in the lab. Here is what that means for your roof.
Cheaper, safer, and free of lithium and cobalt. Sodium-ion batteries are arriving, for homes and the grid.
We run the numbers on payback, time-of-use rates and backup value, with no sales spin.
Everything here is aimed at one thing: helping ordinary households pay less and get more from solar and storage.
Real installed prices per watt, incentive breakdowns, and payback math you can trust, not inflated "savings" claims.
Perovskites, sodium-ion, bifacial panels, microinverters, explained without a physics degree or a sales pitch.
From a plug-in balcony panel to a full off-grid build. Step by step guides, safety checks, and what to leave to a pro.
A snapshot of where the world's clean-energy transition stands. Full interactive charts on the data dashboard.
