Frequently asked questions

What is solar CAPEX and how does it differ from RESCO?+

Solar CAPEX means you own the solar plant outright. You pay the EPC firm to design, procure, build, and commission a turnkey plant on your roof or land. You get the lowest 25-year cost of energy (LCOE around ₹2.40-2.80/kWh against grid HT-I tariff of ₹7.50-9.50/kWh), full asset control, and the 40% Year-1 accelerated depreciation tax benefit. RESCO/OPEX, by contrast, has the developer own the plant; you pay per kWh consumed under a 25-year PPA at ₹4.50-5.50/kWh — zero capex but higher per-kWh cost.

How much does industrial solar CAPEX cost in India in 2026?+

₹3.5-4.0 Cr per MW (DC) for Tier-1 specification: ALMM modules, Sungrow/Huawei inverters, IS-2062 hot-dip galvanized structures, complete BoS, civil and electrical installation, DISCOM net metering, and 1-year free O&M. Coastal sites add 5-7% for salt-protection engineering. Maharashtra projects above 100 kW from April 2026 require mandatory 50% / 2-hour BESS adding ~₹1.05 Cr per MW.

What is the payback period for industrial solar CAPEX?+

3.5-4.5 years for a typical 1 MW industrial rooftop plant on HT-I tariff of ₹7.50-9.50/kWh. The 40% Year-1 accelerated depreciation under Section 32(1)(iia) captures ₹35-40 lakh per MW in tax savings for tax-paying corporates. Net 25-year IRR is 22-28%; lifetime savings ₹38-45 Cr per MW.

Do you take care of DISCOM net metering approval?+

Yes. Sun Wave's in-house DISCOM liaison teams operate across 16+ Indian states, with direct relationships at PVVNL, DHBVN, MSEDCL, GUVNL, BESCOM, TANGEDCO, APSPDCL/EPDCL, TSSPDCL, KSEB, and others. We typically achieve net metering approval in 30-50 days vs the industry-standard 45-90 days.

What performance guarantee do you offer?+

PR (Performance Ratio) ≥78% in Year 1, ≥75% over 25 years (linear degradation), with monetary Liquidated Damages of 1.5-2.0% of contract value per percentage point shortfall, capped at 15-20% of contract value, recoverable from a 10% Performance Bank Guarantee. We refuse to offer 'PR guarantees' without LDs — those are marketing language, not contract obligations.

Is bank financing available for solar CAPEX?+

Yes. SBI, HDFC, ICICI, Axis, Yes Bank, IndusInd, Tata Capital all offer solar term loans at 8.75-9.75% pa with 75-80% LTV and 5-10 year tenor. With 40% Year-1 accelerated depreciation captured against tax, bank-financed solar delivers levered IRR of 35-50% on equity. Madhya Pradesh additionally offers a 5% interest subvention on solar loans above 1 MW for 5 years (effective debt cost 4.5% pa).
