System Capacity Guide
How to Size Rooftop Solar for Kerala Homes (1 kW – 10 kW)
Every home has distinct energy consumption patterns. While 1 kW of solar in Kerala typically produces an annual average of 3.8 to 4.2 units (kWh) per day, your ideal system size depends on your bi-monthly electricity bill, roof space, and sanctioned connected load.
| System Capacity | Shadow-Free Roof Area | Avg. Daily Generation | Recommended For | PM Surya Ghar Subsidy |
|---|---|---|---|---|
| 1 kW Rooftop Plant | 80 – 100 sq.ft | 3.8 – 4.2 Units/day | Small homes with bi-monthly bills under ₹1,500; basic lights, fans & refrigerator. | ₹30,000 flat DBT |
| 2 kW Rooftop Plant | 160 – 200 sq.ft | 7.6 – 8.4 Units/day | 2BHK residences with bi-monthly bills ₹1,500 – ₹3,000; 1 inverter AC or washing machine. | ₹60,000 flat DBT |
| 3 kW Rooftop Plant | 240 – 300 sq.ft | 11.4 – 12.6 Units/day | 3BHK/4BHK family homes with bills ₹3,000 – ₹5,500; 1–2 ACs, water heater, water pump. | ₹78,000 (Maximum Cap) |
| 5 kW Rooftop Plant | 400 – 500 sq.ft | 19.0 – 21.0 Units/day | Large independent houses/villas with bills ₹6,000 – ₹12,000; 2–3 ACs, EV two-wheeler charging. | ₹78,000 flat cap |
| 6 kW Rooftop Plant | 480 – 600 sq.ft | 22.8 – 25.2 Units/day | Joint family residences with bi-monthly bills ₹12,000 – ₹18,000; central cooling & automation. | ₹78,000 flat cap |
| 10 kW Rooftop Plant | 800 – 1,000 sq.ft | 38.0 – 42.0 Units/day | Luxury mansions & estates with bi-monthly bills ₹20,000+; multiple central ACs, 4-wheeler EV charger. | ₹78,000 flat cap |
Essential Factors Affecting Real-World Generation & Sizing:
Customer Trust & Due Diligence
Before You Choose Solar: What Homeowners Should Check
A rooftop solar power plant is a 25+ year infrastructure asset on your house. Before signing an installation contract, ensure your installer provides clear, documented answers to these questions:
Is the Hardware DCR & ALMM Certified?
To receive the PM Surya Ghar central subsidy up to ₹78,000, solar modules MUST be Domestic Content Requirement (DCR) compliant and listed on MNRE’s Approved List of Models & Manufacturers (ALMM).
Product Warranty vs Performance Warranty?
Understand the difference: Tier-1 modules carry a 10–12 year physical product warranty and a 25–30 year linear power performance warranty (≥80% output at year 25/30). Inverters carry 5–10 year manufacturer warranties.
Will the Mounting Structure Withstand Kerala Winds?
Coastal Kerala and elevated rooftops experience squalls over 130–150 km/h. Insist on structural engineer-verified hot-dip galvanized (HDG) steel or high-grade anodized aluminum with SS304 fasteners.
Who Handles KSEB Net Metering & Feasibility?
Your installer must handle the full liaison on KSEB’s eKiran portal, feasibility submission, wiring test certificate, bi-directional meter requisition, and final energisation without leaving you to run to the section office.
Is Dual Earthing & Surge Protection Included?
Kerala has high thunderstorm density. A compliant installation requires separate dedicated copper-bonded chemical earthing pits for AC, DC, and lightning arresters, plus Type-II surge protection devices in the distribution box.
Is There Local Service & Maintenance Support?
Avoid fly-by-night subcontractors. Choose an established Kerala EPC like GSR Energies with local service desks in Malappuram and Kozhikode, dedicated AMC cleaning teams, and active cloud generation monitoring.
