Here’s a detailed breakdown of PLI incentives for solar manufacturing in India:
📐 PLI Incentive Rate Formula
Manufacturers receive incentives based on:
PLI ₹ = Sales Volume (Wp) × Base Rate (₹/Wp) × Tapering Factor × Domestic Value Addition
Where: Sales Volume= total module output sold (in watts peak, Wp)
Base Rate = determined by module efficiency & temperature coefficient
Tapering Factor = 1.4 → 1.2 → 1.0 → 0.8 → 0.6 (Years 1 to 5)
Domestic Value Addition = fraction representing % of local content.
🎯 Base PLI Rates (₹/Wp)
Based on two performance metrics:
Module Efficiency: ≥19.5%, ≥20%, ≥21.5%, >23%
Temperature Coefficient (Pmax): better than –0.30%/°C (Grade B) or between –0.40 to –0.30%/°C (Grade A)
| Temp coeff ↓ / Efficiency → | 19.5–20% | 20–21.5% | 21.5–23% | >23% |
| Grade A (–0.40 to –0.30) | ₹2.5 | ₹3.0 | ₹3.5 | — |
| Grade B (better than –0.30) | ₹2.25 | ₹2.75 | ₹3.25 | ₹3.75 |
(Values below these thresholds receive ₹0)
📉 Tapering Over 5 Years
Once modules go into production:
| Year | Tapering Factor |
| 1 | 1.4 |
| 2 | 1.2 |
| 3 | 1.0 |
| 4 | 0.8 |
| 5 | 0.6 |
This gradually reduces the per-Watt support, nudging competitiveness.
🏭 Putting It in Context.
Suppose a manufacturer sells 100 MW (100,000,000 Wp) modules that meet Grade B efficiency of 21%:
Base Rate = ₹2.75/Wp
Year 1 PLI Factor = 1.4
Assume Local Value Addition = 75% (0.75)
Year 1 PLI:
100,000,000 Wp × ₹2.75 × 1.4 × 0.75 = ₹288.75 crore
PLIs reduce over subsequent years based on tapering factors
Summary
Maximum base rate = ₹3.75/Wp (for >23% eff & Grade B)
Support reduces over time and scales with domestic content
Incentive awarded annually for up to 5 years post‑commissioning.
Bottom line:
Manufacturers are rewarded per watt sold based on module quality, local content, and over a 5‑year tapering schedule. Top-end modules (>23% eff, best temp‑coeff) get up to ₹3.75/Wp before value addition and tapering. Combine that with local value and annual incentives, it's a powerful formula to scale high‑quality module production in India.
Here’s a simple example of how the PLI incentive is calculated for solar manufacturing under the scheme in India:
🔢 Sample PLI Calculation
Let’s assume a company manufactures and sells 100 MW (100,000,000 Wp) of solar modules in Year 1, with the following specs:
| Parameter | Value |
| Module Efficiency | 21.5% |
| Temperature Coefficient | –0.30%/°C (Grade B) |
| Domestic Value Addition| 75% |
| Tapering Factor (Year 1) | 1.4 |
📌 Step-by-Step Calculation
1.Base Incentive Rate for 21.5% efficiency, Grade B = ₹3.25/Wp
2. Total Output = 100,000,000 Wp (100 MW)
3. Value Addition Factor = 0.75
4. Year 1 Tapering Factor = 1.4
✅ Formula.
PLI ₹ = Output (Wp) × Base Rate × Tapering × Local Value Add
✅ Plug the values:
= 100,000,000 × ₹3.25 × 1.4 × 0.75
= ₹341.25 crore (for Year 1)
📉 Year-by-Year Incentive (Same Output & Specs)
| Year | Tapering Factor | PLI Incentive (₹ Cr) |
| 1 | 1.4 | ₹341.25 |
| 2 | 1.2 | ₹292.50 |
| 3 | 1.0 | ₹243.75 |
| 4 | 0.8 | ₹195.00 |
| 5 | 0.6 | ₹146.25 |
| Total (5 years) | — | ₹1,218.75 crore |
🏆 Real Examples of Allocated PLI
| Company | Allocated Capacity | PLI Awarded (Approx.) |
| Reliance Industries | 6,000 MW (fully integrated) | ₹11,900 Cr |
| Adani Infra | 2,000 MW | ₹3,700 Cr |
| Waaree Energies | 6,000 MW | ₹4,100 Cr |
| ReNew Power | 4,800 MW | ₹4,700 Cr |
| Vikram Solar| 2,400 MW | ₹1,800 Cr |
🧾 In Summary
PLI per Wp = ₹2.25 to ₹3.75 based on performance
Tapering ensures lower incentive each year
High local value addition → higher payout
Incentive period: 5 years
Reliance, Adani, Waaree are top beneficiaries
