Frequently Asked Questions

SunstoX is India's first peer-to-peer solar leasing platform. We allow individuals and companies to buy solar cell tokens (representing physical solar panels) and lease them to commercial off-takers — businesses, schools, factories — who pay a monthly tariff per kWh generated. You earn monthly rental income for the 25-year project tenure.

SunstoX Technologies Pvt. Ltd. is registered under the Companies Act 2013 (CIN: U74999DL2024PTC000000) and is a DPIIT-recognised startup. We operate under a lease-rental model, which is governed by contract law. Our CSR projects are registered on the National CSR Portal. We are not an NBFC, MF, or securities issuer — we facilitate direct lease agreements between cell owners and off-takers.

The minimum investment is 1 solar cell, typically priced at ₹700–₹750 depending on the project. There is no upper limit — you can buy as many cells as you like in any active project.

Currently, SunstoX accepts investments from Indian residents (individuals, HUFs, and companies). NRI and foreign investment capability is planned for 2027 under an FDI-compliant structure. Please email kovid@sunstox.com to register your interest.

The target IRR is project-specific, ranging from 10.1% to 13.1% per annum across our current projects. The benchmark NCR Solar Hub project has a target IRR of 10.66% p.a. over 25 years. IRR is based on contractual PPA tariff — not market estimates.

Returns are calculated as: (PPA Tariff × kWh generated by your cells × 80%). The 80% is your share as cell owner; 20% goes to SunstoX for operations and maintenance. Returns escalate 3% per year under the PPA escalation clause and reduce very slightly each year (0.5% degradation) as panels age naturally.

Returns accrue from the Commercial Operation Date (CoD) — the date the solar system is commissioned and starts generating power. There are zero returns during the construction period (7–12 weeks from crowd sale close). Once live, returns are credited monthly on the 1st of each month.

MOIC stands for Multiple on Invested Capital. A 3.24× MOIC means that over 25 years, for every ₹750 invested, you receive approximately ₹2,430 in total rental income. This is the cumulative return on your original investment amount before any reinvestment.

No investment return is ever guaranteed. The 10.66% IRR is a projection based on the contractual PPA tariff (₹5.00/kWh), estimated solar yield (1,550 kWh/kWp/year), 3% annual PPA escalation, and 0.5% panel degradation per year. The main risks are off-taker default and significantly lower-than-expected solar generation. We mitigate both with vetted off-takers, signed PPAs, insurance, and MNRE-certified metering.

Once your KYC is verified and a bank account is linked, you can withdraw any available balance from your dashboard at any time. Transfers are processed via RazorPay Route to your verified bank account within 2 banking days. Minimum withdrawal is ₹500.

Each solar cell token represents ownership of one physical solar photovoltaic cell rated at approximately 4.65 Watts peak (Wp). A typical 65 KWp commercial project contains approximately 4,211 cells. Your cells are identified by serial number and can be physically located and visited on the project rooftop.

SunstoX manages the entire project lifecycle. The EPC partner (e.g., Tata Power Solar, Vikram Solar) installs, commissions, and operates the system under a comprehensive O&M agreement. The system is fully insured against fire, storm, theft, and equipment failure. You have zero maintenance liability as a cell owner.

A secondary marketplace for cell trading is planned for Q3 2026. Until then, cells are illiquid — there is no guaranteed exit before the project end date. Please only invest money you can afford to keep locked for the project tenure.

At project end, the solar system has residual value (typically 10–15% of original cost for the physical hardware). SunstoX will facilitate either a panel buyback, system renewal, or decommissioning — with proceeds distributed to cell owners proportionally. We will notify investors at least 12 months before project end.

Parents buy solar cell tokens that fund a rooftop solar installation on their child's school. The school pays a PPA tariff (₹5/kWh — 41% below DISCOM rates), and that revenue is distributed as monthly rental to parent-investors. Parents earn ~₹607/month from 100 cells (₹75,000 invested), and their child enjoys the perks of being a parent-investor.

Parent investors receive: 5% fee rebate per 5 cells owned, sibling priority admission rights, after-hours STEM lab access, Green Citizen badge on report card, a named tree planted in their child's name, a CO₂ savings dashboard, a signed ownership certificate, their family name on the rooftop panel nameplate, guaranteed science fair slot, advisory vote on school solar committee, early access to new projects, and ₹200 referral bonus per parent referred.

Yes. This is one of SunstoX's signature features. You can direct any percentage of your monthly rental (25%, 50%, or 100%) back to the school's fund — which is used for scholarships, labs, or infrastructure. You can toggle this on/off at any time from your dashboard.

Yes. Solar energy investments qualify under Schedule VII Clause (iv) — Environmental Sustainability and Renewable Energy — of the Companies Act 2013, Section 135. School Solar projects additionally qualify under Clause (ii) — Promotion of Education. SunstoX is registered on the National CSR Portal and provides Form CSR-2 compatible impact data.

Corporate investors receive: Form CSR-1 registration certificate, quarterly impact reports (kWh generated, CO₂ offset, beneficiary count), Board Report Section 135 disclosure template, BRSR Principle 6 (Environment) data pack, REC certificates for carbon credit claims, SDG alignment documentation (SDG 4, 7, 11, 13, 17), and an annual co-branded impact report.

The minimum CSR investment block is ₹5 Lakh (approximately 667 cells). There is no upper limit. Large corporate investors can take a dedicated block in a project — including named corporate sponsorship on project signage.

You need: (1) PAN card — mandatory for all investors for TDS compliance, (2) Aadhaar card — for identity verification, (3) Bank account details — IFSC code, account number, and account holder name matching your PAN. KYC is verified within 24–48 hours.

Your investment buys ownership of physical solar hardware — the money goes directly into project construction, not into SunstoX's accounts. Funds are held in a dedicated escrow account until the system is commissioned. The hardware is comprehensively insured. However, as with all investments, there is risk of capital loss — please read our Risk Disclosure Statement before investing.

Solar rental income is subject to TDS under Section 194I of the Income Tax Act at 10% per annum (if annual income exceeds ₹2.4 Lakhs). SunstoX deducts TDS at source and provides Form 16A annually. You can claim TDS credit while filing your ITR. For corporate investors, TDS treatment differs — please consult your CA.
