Fractional solar ownership can deliver 14–18% IRR with genuine clean energy impact. These five risks are real — here is how careful investors manage each one.
Fractional ownership of solar projects — buying a proportional share of a commissioned or pre-construction plant — has emerged as one of the most accessible ways for Indian retail and HNI investors to deploy capital in clean energy. Ticket sizes start at ₹25 lakh on structured platforms, returns are underpinned by long-term PPAs, and the underlying asset generates stable, currency-denominated cash flows for 25 years. But the structure also concentrates several risks that are easy to overlook when the headline IRR looks attractive. Here is an honest account of each one.
What it is: The industrial or commercial buyer in the PPA stops paying or goes out of business. Without the contracted tariff, income drops to whatever the distressed plant can recover through merchant sale on the exchange — typically 20–40% lower.
How to mitigate: Invest only in projects where the off-taker has been credit-assessed. Key signals: three years of audited accounts, net worth ≥ 5× the annual PPA commitment, and no outstanding dues to their DISCOM. For large MSMEs, insisting on a 3–6 month performance bank guarantee from the off-taker as a contractual condition is common practice and worth verifying before investing. Diversifying across two or three projects with different off-takers substantially reduces concentration risk.
What it is: The plant generates fewer units than the P50 forecast, reducing both income and the IRR you modelled at entry. Generation can underperform due to lower-than-expected irradiance, grid curtailment, panel soiling, inverter downtime, or optimistic initial modelling.
How to mitigate: Ask to see the independent energy yield assessment (EYA) from a reputable third-party firm (DNV, CPPIB-approved assessors, or equivalent) — not just the developer's internal estimate. Distinguish between P50 (median case) and P90 (pessimistic case) output. A responsible developer will show both. For an operating plant, review 12 months of actual generation data against the original P50 forecast. Platforms that show actual vs. projected generation publicly for each asset are demonstrating operational confidence; platforms that do not should be pressed to explain why.
What it is: State governments raise CSS, change banking regulations, impose curtailment orders, or alter the legal framework around Group Captive or Open Access mid-contract. India's power sector regulation is state-concurrent, and while the central framework is stable, state-level decisions can materially affect project economics.
How to mitigate: Prefer projects with executed PPAs (not just MoUs) that include a regulatory change clause — this passes the cost of adverse regulatory changes to the off-taker rather than the project. For Group Captive structures, the CSS exemption is statutory under the Electricity Act 2003, providing stronger protection than SERC orders, which vary. Avoid projects in states with a history of recent, unexplained curtailment orders or pending high-court challenges to renewable power banking.
What it is: Unlike a listed equity or mutual fund, a fractional solar stake is illiquid. If you need your capital back before the PPA term ends, you must find a willing buyer. In India's current market, secondary trading of fractional solar positions is thin outside of structured platforms — and even on platforms, exit timelines can be 6–18 months.
How to mitigate: Treat solar fractional ownership as a 5–15 year deployment, not a 2-year trade. Size your position so that the locked-up capital does not impair your liquidity runway. Ask platforms directly: what is the average secondary exit timeline for completed projects on your platform? How many secondary sales have been completed in the last 12 months? A credible operator will answer with data. If they cannot, that itself is a due-diligence signal.
What it is: You invest in a fractional share of an SPV or project, but the underlying land lease, grid connection approval, CEIG clearance, or module procurement is legally defective. In the worst cases, projects have been sold to multiple investors through informal arrangements with no registered share transfer — leaving investors with no enforceable legal claim.
How to mitigate: This is where platform governance matters more than IRR projections. Before investing, confirm: (a) your shareholding will be registered in the SPV's statutory register with an MCA-compliant share certificate; (b) the land lease is registered (not just a notarised agreement); (c) grid connectivity approval is from the DISCOM on record; and (d) modules are on the ALMM list (Ministry of New and Renewable Energy list of approved manufacturers). Platforms that publish these documents in their information memorandum are operating responsibly. Those that do not are creating unnecessary legal exposure for their investors.
None of these items are unusual to request. Any developer or platform that is reluctant to provide them is signalling something about the quality of their underlying documentation.
