Solar vs Grid — School / College
25-year LCOE of rooftop solar against escalating grid tariffs for a school / college.
Campuses use power exactly when solar produces, then vacation through the weakest months — self-consumption alignment plus daytime load makes school rooftops near-ideal.
LCOE = (capex + lifetime O&M) ÷ lifetime energy, degradation included. For a school / college, solar's ₹1.8/kWh is locked for 25 years while the grid escalates — the comparison gets more lopsided every tariff order.

Frequently asked questions
What is LCOE and why use it to compare solar with the grid?+
Levelized Cost of Energy: (capex + lifetime O&M) ÷ lifetime kWh, degradation included — solar's all-in price per unit across 25 years. It's the apples-to-apples number against grid tariffs: rooftop LCOE of ₹2.5–4 versus grid rates of ₹7–12 is the whole argument in one line.
Is solar really cheaper than grid power now?+
For most Indian consumers, decisively: commercial rooftop LCOE runs ₹2.5–3.5 against ₹8–12 tariffs; residential ₹3–4.5 against ₹6–9 marginal slabs. The gap widens annually as tariffs escalate ~3–5% while solar's cost is locked at installation. Low-tariff, low-sun cases deserve the math — which is what this tool runs.
What tariff escalation should I assume?+
Indian retail tariffs have averaged 3–5%/yr over long periods (fuel surcharges add spikes). Use 4% as a fair base; even 0% (impossibly conservative) usually leaves solar ahead. The output shows the 25-year average grid rate so the assumption is visible, not buried.
Does the comparison include batteries?+
No — this is solar-vs-grid energy price. Storage adds ₹4–7/kWh of throughput cost (see the battery tools) and buys you evening/backup value rather than cheaper energy. The honest sequence: solar first (clear win), storage where outages or ToU spreads justify it.
