5 kW solar system for Kerala homes.
For larger homes and homes with several air conditioners. The figures below are a typical estimate, worked out from our 3 kW and 8 kW proposals. Your quote is made for your roof.
A 5 kW system in numbers.
This is a typical estimate, not a quote. We worked it out from our real 3 kW proposal (₹2,05,000) and 8 kW proposal (₹4,00,000), using the same components.
| System | About 5 kWp, grid-connected, single or three phase depending on your connection |
|---|---|
| Panels | 9 × 550 Wp DCR panels (4.95 kWp), so you keep the full subsidy |
| Inverter | 5 kW on-grid inverter with online monitoring |
| Roof area | About 450 to 500 sq.ft, flat or sloped |
| Generation, clear day | About 20 to 25 units a day |
| Generation, year-round average | About 17 to 18 units a day, around 520 units a month |
| Estimated price | ₹2,80,000 to ₹3,10,000 for design, supply, installation and commissioning |
| PM Surya Ghar subsidy | ₹78,000, so about ₹2,02,000 to ₹2,32,000 after subsidy |
| Timeline | Materials within 7 days of the advance, installation within 7 to 15 days of delivery, and commissioning within 10 days of installation and KSEB approval |
Clear-day figures are from our proposals and depend on the site. The year-round average uses the same Kerala assumptions as our solar calculator and includes the monsoon months. Your roof's direction, tilt and shade change the real numbers, which we measure on the free site visit.
What goes into a 5 kW system.
| Component | Specification | Make | Qty |
|---|---|---|---|
| Solar panels | 550 Wp Mono PERC / bifacial, DCR | Adani / Waaree / Vikram | 9 |
| Inverter | 5 kW single or three-phase on-grid inverter with online monitoring | Solis / Growatt / Polycab | 1 |
| DC distribution box | PV fuses at input, DC isolator, Type-2 DC surge protection, IP65 enclosure | ABB / Eaton / Mersen | 1 |
| AC distribution box | MCB and Type-2 AC surge protection, IP54 enclosure | ABB / Eaton / Mersen / Citel | 1 |
| DC cables | UV-rated solar copper cable, cross-linked sheath and insulation | Apar / Seichem | As needed |
| AC cables | PVC/XLPE aluminium or copper, sized to load | Apar / Polycab | As needed |
| Earthing | Maintenance-free chemical earthing, copper-bonded rod (14 mm, 1.2 m) | Excel Earthing | 2 sets |
| Lightning protection | Single-spike air termination rod, insulated base, chemical earth kit | Excel Earthing | 1 set |
| Solar energy meter | Watt-hour meter for generation monitoring | L&T | 1 |
| Mounting structure | Hot-dip galvanised / epoxy-coated GP tubes for flat or sloped roofs | Apollo | 1 set |
Same balance-of-system parts as our 3 kW and 8 kW systems. Higher-wattage TOPCon panels are also available; we will tell you if a panel choice affects the subsidy.
Right for homes using 450 units a month or more.
A 5 kW system suits homes with two or three air conditioners, a large family, daily induction cooking, or an electric car charged at home. If your KSEB bill shows 450 to 550 units a month (900 to 1,100 units for a two-month bill), 5 kW covers most of it.
The subsidy is the same ₹78,000 as for 3 kW, but higher-use homes pay more per unit under KSEB's slab rates, so each unit solar replaces is worth more to them.
Whether 5 kW runs on your single-phase connection or needs three phase depends on your connected load and KSEB's rules. Load enhancement or three-phase conversion, if needed, is quoted separately.
