A complete guide to 5 kW rooftop solar — who it suits, how it's installed, and what affects the price.
A 5 kW rooftop solar system typically suits larger homes with a monthly electricity bill in the ₹5,000–8,000 range. It needs roughly 450–500 sq.ft of shade-free roof space and generates approximately 600–650 units per month under typical Lucknow conditions — using 8–10 panels depending on wattage.
Typically 8–10 panels of 500–550W, depending on brand and wattage chosen.
A 5 kW-rated on-grid, hybrid or off-grid inverter, matched to your system type.
Sized and specified for your roof type — RCC, tin/metal or tile.
Answer four quick questions — no phone number required to see indicative numbers.
Estimated range only. Never a promised bill. Actual savings depend on site survey, DISCOM rules, sanctioned load, tariff slab and real generation. PM Surya Ghar subsidy slabs as of August 2026 — verify current rate on pmsuryaghar.gov.in.
Golden ACS doesn't publish a fixed 5 kW price online because it depends on panel brand, inverter brand and mounting structure — see Solar Panel Price in Lucknow for the full picture, or request a free site survey for an itemised quote. A 5 kW residential system is eligible for the maximum PM Surya Ghar subsidy of ₹78,000 (the cap applies from 3 kW onwards).
Installation of a 5 kW system typically takes 1–3 days once components are on-site. We then handle the DISCOM net metering application so surplus power can be exported to the grid — see our full installation process for the complete timeline.
As with any system size, exact pricing depends on the components chosen. Use the calculator on this page for an indicative range, or request a free site survey for an exact, itemised quote.
Indicatively, a 5 kW system generates roughly 600–650 units per month under typical Lucknow sun-hours, though actual output varies with shading, orientation, panel technology and season.
Typically 8–10 panels for a 5 kW system, depending on the wattage of the panel used (commonly 500–550W panels today). Your site survey will confirm the exact panel count and layout.
It depends on your system size, panel output and whether the ACs run during sunlight hours. A 3–5 kW system can typically support daytime AC use alongside other home load, but we size this exactly during your site survey based on your sanctioned load and usage pattern.
