Technology FAQ
Common questions about solar technology
Should I wait for better panel technology?
Current panels (21–22% efficiency) are already excellent. Waiting for tandem cells means 2+ more years of paying full electricity bills. The panels you buy today will produce power for 25–30 years – the ROI case is strong right now.
Do bifacial panels work on residential roofs?
Bifacial panels work best on ground mounts or flat roofs where light can reach the back. On pitched roofs, the snow-reflection benefit is still real but smaller. They cost 5–10% more – worth it in snowy regions, less so elsewhere.
When will sodium-ion batteries be available in Canada?
First residential sodium-ion units are expected in Canadian markets by Q4 2026. Early adopters will likely see pricing 30–40% below comparable lithium-ion systems, with better cold-weather performance – a significant advantage for Canadian installations.
