Warranty commitments on core products plus lifetime technical support
12-year product workmanship and materials warranty, plus a 25-year linear power warranty: degradation ≤2% in the first year and ≤0.55% per year thereafter. [示例值，客户可改]
5-year whole-unit warranty with free repair or replacement for covered failures; optional extension up to 10 years available. [示例值，客户可改]
5-10 year warranty on LiFePO4 batteries (depending on product series), with capacity retention of no less than 70% within the warranty period. [示例值，客户可改]
Lifetime technical consulting and remote diagnosis, after-sales response within 48 hours, and on-site service for major failures. [示例值，客户可改]

The payback period depends on system capacity, local solar resources, electricity prices and subsidy policies. Residential systems typically pay back in about 5-8 years, while C&I self-consumption projects take about 3-6 years. With a design life of over 25 years, the remaining years generate net profit.

Yes. PV modules still generate power under low-light conditions, though output drops significantly — typically around 10%-30% of a sunny day. Pairing the system with energy storage further secures power supply on cloudy days.
We assist throughout the entire process. Our project team helps prepare grid-connection application documents and works with the local utility on registration, acceptance and commissioning — you only need to provide the relevant certificates and paperwork.
Cleaning 1-2 times per year is recommended depending on the local environment. Dust and bird droppings reduce generation efficiency; rainfall usually provides natural cleaning, while dusty or arid regions may need manual washing or automatic cleaning equipment.
Call our after-sales hotline at 183-3187-3999. We respond within 48 hours: issues solvable by remote diagnosis are handled immediately, and engineers are dispatched when on-site service is needed. Repairs and replacements covered by warranty are free of charge. [示例值，客户可改]
Yes. We provide detailed installation manuals, video tutorials and remote video guidance for overseas projects. For large-scale projects, engineers can be dispatched on site to deliver installation training and technical supervision, ensuring construction follows standards.
PV modules are designed for a 25-30 year service life and retain over 80% of their generation capacity after 25 years. Inverters typically last 10-15 years and can be replaced when due, so the plant as a whole can keep operating for more than 25 years. [示例值，客户可改]
