Frequently Asked Questions
What rooftop space is needed for a 20KW system?
A 20KW system requires approximately 120–140 square meters of unshaded roof space for standard 400W panels. FSOLAR conducts a free site survey to confirm feasibility.
Does a 20KW system need 3-phase power?
Yes. 20KW commercial systems typically use 3-phase inverters which require a 3-phase electricity supply — common in all UAE commercial properties. FSOLAR verifies your supply configuration before system design.
Can a 20KW solar system eliminate my electricity bill?
For businesses with moderate consumption (under 4,000 kWh/month), a 20KW system can cover 80–100% of electricity needs. High-consumption businesses may need a larger 30–50KW system.
What warranty comes with a 20KW commercial system?
FSOLAR provides: 5–10 year inverter warranty, 25-year panel performance warranty (80% output), 10-year battery warranty (Pylontech/CATL), and 2-year installation workmanship guarantee.
