* "Free electricity for 25 years" refers to the expected lifespan and energy generation capacity of the solar power system, not zero-cost installation.
The customer must bear the initial cost of solar system installation, which may be partially offset by applicable government subsidies.
Actual savings and bill reduction depend on:
System size and configuration,
Daily energy consumption,
Sunlight availability and weather conditions,
Maintenance and cleaning of panels.
Electricity bills may not be completely eliminated due to:
Fixed charges by the local electricity authority,
Night-time grid usage (for on-grid systems),
Government subsidy amounts, eligibility, and disbursement timelines are subject to policies under schemes like PM Surya Ghar: Muft Bijli Yojana and may change without prior notice. System performance may degrade gradually over time (typically ~0.5%–1% annually).
The 25-year period is based on industry-standard solar panel performance warranties, not a guarantee of zero electricity bills.
Maintenance, inverter replacement (if applicable), and other operational costs are not included in the "free electricity" claim.
