1. The Impact of Government Subsidies
Real-World Example:
Consider a housing society with 100 homes, each eligible for a 3 kW solar system. The total capacity eligible for subsidy would be 300 kW. At the current subsidy rate of ₹18,000 per kW, this community could receive a subsidy of ₹54 lakhs. If the cost of installation using Domestic Content Requirement (DCR) panels is around ₹52,000 to ₹60,000 per kW, the subsidy reduces this cost to approximately ₹34,000 to ₹42,000 per kW.
- Installation Cost Before Subsidy: ₹52,00,000 to ₹60,00,000
- Installation Cost After Subsidy: ₹34,00,000 to ₹42,00,000
This significant reduction in upfront costs makes solar energy a much more attractive investment for RWAs and GHSs.
2. Long-Term Savings: Maximizing Financial Benefits
Real-World Example:
- Annual Energy Generation: 100 kW × 4.5 units/day × 365 days = 1,64,250 units
- Annual Savings: 1,64,250 units × ₹6.62 per unit = ₹10,86,315
These savings accumulate year after year, providing a substantial financial cushion for the community.
3. Return on Investment (ROI) and Payback Period
Payback Period Calculation:
4. Enhancing Property Value
Real-World Example:
A GHS with a robust solar installation may see its property values increase by 3-4%, as prospective buyers recognize the long-term financial benefits of lower electricity bills. This added value can make the community more desirable and potentially increase demand for housing within it.
