ONVALLA’s solar warranty covers both product quality and performance: panels are guaranteed free of material and manufacturing defects for the specified period, and most panels are warranted to keep at least 80% of their initial output for up to 25 years. Inverters and batteries carry their own clearly defined warranties, and ONVALLA backs the system with inspection, maintenance, repair and technical support.
A strong warranty is one of the most important factors when choosing solar, because it reduces long-term risk on a large investment.
