Easy Solar Panel Maintenance - Energy Collective (opens the original)
Read excerpt
Most home solar systems keep at least 80% of their original power output after 25 years, the US Department of Energy says, and the maintenance behind that number is mostly staying out of the way. Panels have no wiring that moves and nothing that spins, so the routine care is a seasonal wash for the glass and a yearly check of the wiring and mounts. The parts that cut into what a system produces are dirt and snow on the glass, plus an inverter with a shorter working life than the panels above it.
Boost Solar Panel Efficiency: 10 Expert Tips - Energy Collective (opens the original)
Read excerpt
Solar panel efficiency is the share of sunlight a panel turns into electricity, and residential panels sold in 2026 typically run from about 21% to nearly 25%. That’s far above the less than 10% efficiency of the panels sold in the mid-1980s, but it’s still a lab number, measured under standardized test conditions. A panel bolted to your roof rarely hits its spec-sheet number, because heat, shade, dust and the wrong angle all take a bite out of it, and most of the fixes cost you nothing. The num
How solar inverter efficiency works - Energy Collective (opens the original)
Read excerpt
A solar inverter’s efficiency is the share of the panels’ DC power that comes out the other side as usable AC power, and one home inverter on the market converts 99.2% of it under test conditions, per its maker’s own spec sheet. That headline number isn’t the one that predicts your power bill. The test protocol California adopted from Sandia National Laboratories produces a second, lower “weighted” number built from how an inverter performs across a full day. How hot the box runs and how the arr
Offshore Wind Farms: Powering a Clean Future - Energy Collective (opens the original)
Read excerpt
Offshore wind power comes from turbines standing in the ocean or floating above it, and the world had 92.5 gigawatts of it running by the end of 2025, within reach of the 100 gigawatt mark. The US has far less of it. Its two offshore wind farms had a combined 304 megawatts running at the end of 2024. That adds up EIA’s separately reported 130 and 174 megawatt totals for South Fork Wind and Vineyard Wind 1. A new US project costs about $125 per megawatt-hour to build, and most of the ones under c
Japan's offshore wind buildout is years behind its own targets - Energy Collective (opens the original)
Read excerpt
Japan wants 10 GW of offshore wind running by 2030, building toward 30 to 45 GW by 2040. It had only 253.4 megawatts in the water at the end of 2024, which is why last year’s biggest industry setback still stings. A Mitsubishi-led consortium walked away from 1.7 GW of projects it had already won, telling investors in August 2025 that the numbers no longer worked. The government has spent the months since rewriting its own auction rules and opening a much larger stretch of ocean to the floating t
