• Residential system reduces electricity costs and supports energy independence

Frequently Asked Questions

How much electricity can a 20kW system generate in Israel?

Under Israel's solar conditions, a 20kW BIPV system typically generates around 28,000–34,000 kWh per year, covering most residential consumption and reducing grid dependency.

Can the 15kWh battery power a home at night?

Yes. The 15 kWh lithium battery stores excess daytime energy for night-time use, supporting essential loads (lighting, refrigerator, AC) and extending backup power during grid outages.

What is the warranty for this system?

GreenMore BIPV solar tiles carry a 25-year linear power warranty. The inverter and lithium battery carry a 3-year warranty. Remote diagnostics and spare parts support available for partners across our target regions.

Is this system suitable for off-grid homes?

Yes. The 15kW off-grid inverter and 15kWh battery are designed for off-grid and hybrid operation, ideal for homes with unstable grid connection or complete energy independence requirements.
