Solar for Schools and Colleges in Hyderabad
Cost, Savings, Approval Process and Ownership Models — Complete 2026 Guide
Updated May 2026 | By Sri Ishaan Solar Team
Educational institutions are among the best candidates for solar energy in Hyderabad. Schools and colleges run largely between 8AM and 4PM — exactly when solar generation is at its peak. With large flat rooftops and consistent electricity consumption, the economics are compelling. This guide covers everything a school management committee or college bursar needs to know before making the decision.
Why Schools Are Ideal Solar Candidates
- Perfect load-generation match: School hours (8AM–4PM) align precisely with peak solar output (9AM–3PM). Very little generation is wasted.
- Large flat rooftops: Most school buildings have extensive flat terraces ideal for panel installation without shading concerns.
- High electricity bills: Air-conditioned classrooms, computer labs, science labs, and cafeterias make electricity one of the biggest operational costs.
- Net metering benefit: On weekends, holidays, and vacations, surplus power exports to the TSSPDCL grid and earns billing credit.
- Brand value: A solar installation is a visible, powerful statement about environmental responsibility that resonates with parents and students.
Typical System Sizes for Educational Institutions
| Institution Type | Typical Size | Monthly Generation |
|---|---|---|
| Small school (up to 300 students) | 20–30 kW | 2,400–3,600 units |
| Medium school (300–800 students) | 30–60 kW | 3,600–7,200 units |
| Large school / junior college | 60–100 kW | 7,200–12,000 units |
| Degree / engineering college | 100–500 kW | 12,000–60,000 units |
Cost and Savings: 20kW, 50kW, and 100kW Systems
Note: PM Surya Ghar (PMSG) subsidy does not apply to educational institutions — this is a residential-only scheme. Commercial institutions on TSSPDCL LT-2 tariff pay ₹7–9/unit.
| System Size | Gross Cost (approx.) | Monthly Generation | Monthly Savings (at ₹8/unit) | Payback Period |
|---|---|---|---|---|
| 20 kW | ₹9–11 lakh | ~2,400 units | ~₹19,200 | 4–5 years |
| 50 kW | ₹22–27 lakh | ~6,000 units | ~₹48,000 | 4–5 years |
| 100 kW | ₹42–52 lakh | ~12,000 units | ~₹96,000 | 4–5 years |
Ownership Models: CAPEX vs RESCO/OPEX
CAPEX Model (School Owns the System)
The school purchases and owns the solar system outright. All savings go directly to the school from day one. This is the most financially rewarding model over the long term. Typical financing options include school corpus funds, bank loans (solar loans at 8–10% PA), or CSR grants from corporate partners.
Best for: Schools with available capital or access to education institution bank loans. Maximum long-term savings.
RESCO / OPEX Model (Zero Upfront)
A solar developer installs the system on your roof at zero upfront cost. The school pays a fixed per-unit tariff (typically ₹4–5 per unit) for electricity consumed — substantially less than the TSSPDCL commercial rate of ₹7–9 per unit. The developer owns and maintains the system for 15–20 years, after which it transfers to the school.
Best for: Schools with no capital budget for solar but want to reduce electricity costs immediately. Zero financial risk.
TSSPDCL Net Metering for Schools
Schools and colleges connected to TSSPDCL on the LT-2 (non-domestic / commercial) tariff are eligible for net metering. Here is how it works in practice:
- During school hours: solar powers the building directly, reducing consumption from the grid
- During breaks, weekends, and summer vacations: surplus solar exports to the TSSPDCL grid
- Exported units earn billing credit at the applicable rate, reducing the next electricity bill
- Annual settlement: any remaining net export credit is settled at the end of the financial year
Approval Process for School Solar in Hyderabad
Sri Ishaan Solar manages the entire approval process on behalf of the institution:
- TSSPDCL application for net metering NOC
- Technical feasibility check by DISCOM engineer
- Installation by TGREDCO-registered installer (Sri Ishaan Solar: TSRE260936)
- Net meter installation by TSSPDCL
- CEIG clearance — required only for systems above 100kW
Total approval timeline: 4–8 weeks. Installation: 3–7 days depending on system size.
Tax Benefit: 40% Accelerated Depreciation
Educational trusts and private schools registered as companies can claim 40% accelerated depreciation on the solar system value in the first year under the Income Tax Act. This substantially reduces the effective cost of the system for institutions paying income tax. Consult your chartered accountant to confirm eligibility based on your institution's registration type.

Can a private school use the PM Surya Ghar subsidy?
No. The PM Surya Ghar Muft Bijli Yojana subsidy applies only to individual residential consumers. Schools, colleges, and all commercial/institutional establishments are not eligible. However, institutions benefit from net metering, accelerated depreciation, and potentially state-level incentives for renewable energy.
What is the RESCO model for solar?
In the RESCO (Renewable Energy Service Company) model, a developer installs a solar system on your roof at zero upfront cost. You pay only for the units generated, at a rate lower than your current electricity tariff. After 15–20 years, the system transfers to you. It is essentially a Power Purchase Agreement (PPA) for rooftop solar.
How many kW of solar does a school with 500 students need?
It depends more on your electricity bill than student count. A school consuming 8,000–12,000 units/month with 500 students and moderate AC usage would need approximately 25–40kW. We recommend sharing your last 3 electricity bills for an accurate sizing recommendation.
Does TSSPDCL allow net metering for schools?
Yes. Schools on LT-2 tariff (non-domestic) are eligible for net metering. Surplus generation during holidays exports to the grid and reduces your next bill. This is particularly valuable for schools that are closed 3–4 months a year during summer and semester breaks.
What approvals are needed for a 50kW school solar system?
For systems up to 100kW: TSSPDCL net metering NOC and net meter installation. No CEIG clearance needed. Sri Ishaan Solar handles all paperwork and coordinates directly with TSSPDCL as part of our installation service.
