Overview
Residential rooftop solar in Darbhanga
A home rooftop plant is the fastest way for a Bihar family to stop worrying about rising tariffs. A well-designed 3 kW system in Darbhanga generates roughly 360–450 units a month — more than most households consume — so your monthly bill drops to the minimum fixed charge while the surplus is banked with the DISCOM through net metering.
Apex Solar Power Solutions surveys your roof free of cost, measures shadow-free area, studies twelve months of your bills, and then proposes a system size that actually matches your usage. We never oversell kilowatts you will not use, and we never undersize a plant just to look cheap in a quotation.
At a glance
TypicalExact figures depend on your roof, shading and load. We confirm them in writing after a free survey.
What you get
Four things that decide whether this works
Right-sized design
Load study from your last 12 bills, shadow analysis of the roof, then a system size that fits both — typically 2 kW to 5 kW for a family home.
Both subsidies claimed
Up to ₹78,000 central plus ₹20,000 from the Bihar Government. We file both, coordinate the DISCOM inspection, and follow the money till it reaches your bank account.
Cyclone-grade mounting
Hot-dip galvanised structures rated for Bihar wind loads, proper earthing and a lightning arrester on every installation.
Service that answers
Five free cleaning and health-check visits in the first year, then an affordable AMC. We are 20 minutes away from most Darbhanga roofs.
Questions
About residential rooftop solar
About 240–250 square feet of completely shadow-free roof. On a typical Darbhanga house the front or rear portion of the terrace is enough — we confirm the exact layout during the free survey.
Yes. A 3–5 kW on-grid system comfortably supports a 1.5-ton AC during daylight hours. If you also want the AC to run during a power cut, we would recommend a hybrid system with a battery bank instead.
Generation drops but does not stop. Because an on-grid system is connected to the DISCOM supply, your home simply draws the shortfall from the grid and your net meter adjusts it against the units you exported on sunny days.
