Over Easy Solar Launches 256W Vertical Rooftop Solar Unit for Urban Installations

Over Easy Solar has introduced a lightweight, high-efficiency 256W vertical rooftop solar panel designed for urban environments.

Over Easy Solar launched the xM-3 Quattro-256S, a 256W vertical rooftop photovoltaic unit optimized for urban installations. This panel features silicon heterojunction (HJT) cells with 95% bifaciality, delivering 256W at standard test conditions with 3% power tolerance across 2.31m² of roof space. It weighs 28.4kg and operates within -40°C to 85°C, incorporating tempered glass and IP68-rated components for durability. The unit includes 15-year product and 25-year power-output warranties, with certifications meeting IEC/EN 61215, IEC/EN 61730, and UL 61730 standards. It ships 27 units (6.9kWp) per pallet and supports multiple roof types including green roofs and heavy snowfall regions.

This design enables cheaper urban rooftop solar by reducing weight and improving efficiency. The panel’s lighter profile (28.4kg vs conventional panels) and higher bifaciality allow more energy capture per square meter while maintaining robust performance in diverse climates. Its low annual degradation rate (0.583%) and 19g CO₂e/kWh footprint further support long-term cost and environmental benefits.

For urban households and businesses, this unit makes rooftop solar more accessible by lowering installation friction and upfront costs. Cheaper, lighter panels enable wider adoption on constrained urban roofs where space and weight are critical barriers. The unit’s scalability—shipped in pallets of 27 units—suggests potential for rapid deployment in cities.

What to watch: Real-world performance in varied climates and the pace of scaling production to meet urban demand. The source text erroneously states a publication date of September 30, 2026—a future date that contradicts current year (2023) and is not part of the product’s specifications.
