How Many Solar Panels Do You Need for a 300, 500, or 1000 Unit Bill in Hyderabad?
Determining the right solar system capacity starts with your TSSPDCL monthly electricity consumption (kWh units). In Hyderabad, electricity tariffs are structured in escalating teleslab tiers—exceeding 300, 500, or 800 units per month pushes your tariff rate up to ₹9.50–₹10.50 per unit. Correctly sizing your rooftop solar array eliminates these high-slab charges and reduces your monthly electricity bill to near-zero.

Exact Sizing Calculations for Hyderabad Households
In Hyderabad's solar climate, each 1kW of properly oriented on-grid solar generates an average of 4 to 4.5 kWh (units) per day, translating to 120 to 140 units per month across the year. Therefore, offsetting a 500-unit monthly bill requires a 4kW to 5kW solar system. Using high-efficiency 550Wp Mono PERC or TopCon modules, a 5kW system requires just 9 solar panels covering approximately 350 to 400 square feet of terrace area.
Under TSSPDCL's net metering framework, solar power generated during the day first supplies your real-time household loads. Any excess is exported back to the grid and recorded on your bidirectional meter. At the end of the monthly billing cycle, your exported solar units are subtracted 1:1 from your imported grid units, effectively erasing your high-tier electricity bills.
- 300 Units/mo: Requires 2kW–3kW system (5 to 6 panels | ₹50,000–₹1,17,000 net after subsidy).
- 500 Units/mo: Requires 4kW–5kW system (8 to 9 panels | ₹1,72,000–₹2,32,000 net after subsidy).
- 1,000 Units/mo: Requires 8kW–10kW system (15 to 18 panels | ₹4,02,000–₹5,02,000 net after subsidy).

520-Unit Monthly Bill Wiped Out with 4.5kW Setup
A 3BHK independent house in Nizampet with heavy summer AC usage had average monthly TSSPDCL bills of ₹5,200 (520 units). Solar Cubic engineered an 8-panel 4.4kW Mono PERC system with an on-grid inverter. The system yields an average of 540 units/month, reducing the owner's net electricity bill to just the fixed service charge of ₹120.
