The next U.S. spacewalk is scheduled for Monday, Dec. 19, to install an iROSA on the 4A power channel on the port truss. This will be the fourth iROSAs out of a total six planned for installation. The iROSAs will increase
Cassada and Rubio completed their major objectives for today to install an International Space Station Roll-Out Solar Array (iROSA) on the 4A power channel on the port truss. The iROSAs will increase power generation

The International Space Station is larger than a six-bedroom house with six sleeping quarters, two bathrooms, a gym, and a 360-degree view bay window. The crew is installing new IROSAs, or International Space Station Roll-Out Solar Arrays, to augment the orbiting lab’s eight main solar arrays.
The power system upgrades over the next couple of years will restore the space station’s electrical grid to the same output as when the original arrays were first installed, NASA said. That represents a 20% to 30% increase over the current power levels.
The space station has been continuously occupied since November 2000. An international crew of seven people live and work while traveling at a speed of five miles per second, orbiting Earth about every 90 minutes. Sometimes more are aboard the station during a crew handover.
To provide context, consider two examples of space systems with significant mass and solar panel area: an aggregated mass, the International Space Station (ISS); and a distributed mass, a constellation of 4,000 Starlink v2.0 satellites4. The solar panel area is 11.5km2 for RD1 and 19km2 for RD2.
The crew is installing new IROSAs, or International Space Station Roll-Out Solar Arrays, to augment the orbiting lab’s eight main solar arrays. Five space agencies including NASA, Roscosmos, ESA (European Space Agency), JAXA (Japan Aerospace Exploration Agency), and CSA (Canadian Space Agency), have contributed to the station’s assembly.
NASA says each roll-out solar array can produce more than 20 kilowatts of power. Four more iROSA wings will launch on future Cargo Dragon missions in 2022 and 2023. Combined, the six iROSA wings will generate more than 120 kilowatts of electricity, enough to power more than 40 average U.S. homes.
The European energy storage market is booming with Germany leading residential adoption (+58% YoY) thanks to €500/kWh subsidies. Italy's new tax credits drive 5.2GWh commercial deployments, while UK grid-scale projects exceed 8GWh with 2-hour duration systems. Key selection criteria: German-certified safety (VDE-AR-E 2510), 10+ year warranties, and VPP readiness. Top-performing products include Sonnen's hybrid inverters (98% efficiency) and BYD's Blade Battery (12,000 cycles @80% DoD). For snowy regions like Scandinavia, consider Huawei's -30°C compatible systems. France mandates carbon footprint declarations - Sungrow's ISO-14067 certified solutions gain preference.
For European homeowners, 5-10kWh systems with 3-phase compatibility are ideal. Top picks: 1) Tesla Powerwall 3 (13.5kWh, 97% round-trip efficiency) for smart home integration; 2) LG Chem RESU Prime for compact urban installations; 3) SMA Sunny Boy Storage for retrofit projects. Critical features: EU-made battery cells (exempt from CBAM tariffs), dynamic tariff optimization (like Octopus Energy integration), and fire-safe LiFePO4 chemistry. Southern Europe demands 85%+ depth of discharge capability, while Nordic markets require -25°C operation. Always verify CEI 0-21 compliance for Italian grid connection and EnWG certification for German feed-in.
