The Hidden Problem With the World's Most Efficient Solar Panel
After Years of Perovskite Promises, Does This One Deliver? Take your personal data back with Incogni! Use code UNDECIDED at the link below and get 60% off an annual plan: http://incogni.com/undecided A California startup called Tandem PV says it has built the most efficient solar panel on the planet, hitting 30.4% efficiency where today's best silicon solar panels top out around 25%. That number came from the company's own lab, and the test module is barely bigger than a coaster. On the same day, a rival posted an independently verified result that beat it anyway. Perovskite solar panels have promised this kind of efficiency leap for years, but durability has always been the catch, and Tandem PV says it finally solved it. So is this really the world's most efficient solar panel? Or is Tandem PV's big claim more marketing than reality? Massive thanks to @TwoBitDaVinci for hosting this one!

Growatt SPM 6000TL-HU – app/manual mismatch, commissioning currently broken
I recently installed a Growatt SPM 6000TL-HU with a Growatt HOPE battery. The inverter itself works fine locally: charging, backup mode and BMS communication are all OK. The problem is the software/commissioning. My supplied manual says the SPM can be commissioned through internal Bluetooth using ShineTools, then connected to Wi-Fi. In the current ShineTools 3.6.7.0, SPM 6000TL-HU is not even available in the Direct WiFi/Bluetooth device list.
Can energy security and climate action work together? From Climate Week NYC
Energy security has surged up the policy agenda as geopolitical shocks have exposed the risks of relying on imported fuels. But replacing oil and gas with renewables, batteries and electric vehicles can create new dependencies of its own. The question running through Climate Week NYC was whether countries can strengthen energy resilience while curbing greenhouse gas emissions. Host Ed Crooks held a series of conversations with leaders in energy policy and business about managing the trade-offs between energy security and climate action. First,

Sound insulation
Hi guys! I'm very new to this whole thing, I've recently decided to buy a van next year. The problem is, I'm a terribly light sleeper and very sensitive to noise in general....I have not looked into too many details but of course I'm definitely going to install extra sound insulation no matter what make I buy. However, my question is, strictly from the perspective of sound insulation, what should i go for: a cargo van or a passenger van with lots of windows?
