How Zynexis Computes Your Solar Sizing

1

Daily Watt-Hour Consumption

We sum the rated wattage of each active appliance multiplied by its quantity and estimated hours of daily usage. This yields total kilowatt-hours (kWh) consumed per day.

2

Peak Sunshine Hours Factor

India receives an average of 4 to 5.5 peak sun hours per day. Dividing daily units by the conservative 4-hour benchmark determines the minimum peak kW panel capacity required.

3

Net Metering & Subsidy Credit

We apply the official PM Surya Ghar subsidy scale (₹78,000 Central Govt Subsidy + ₹20,000 State Govt Subsidy, total up to ₹98,000; T&C apply under residential, min 3kW, max no limit) and estimate monthly bill offsets based on DISCOM bi-directional net metering tariffs.

Concessional Green Financing • Zero Down Payment

Instant Bank Facility • Lowest Interest Rates

Avail instant bank facility with zero down payment and the lowest interest rates (starting at ~7% p.a.) via leading nationalized banks (SBI, PNB, Canara Bank). Your monthly electricity savings easily exceed the EMI, making solar virtually free from day one!
