SunstoX is a platform-as-a-service for Independent Power Producers. Register your project, pass our verification process, and open a public investment tranche — so retail investors can buy-to-lease solar cells in your project and fund your installation.
SunstoX handles the investment platform, KYC, payment collection, and monthly payout distribution. You focus on building and operating the project.
Create your IPP account on SunstoX. Fill in project details — capacity, PPA tariff, location, EPC partner and CoD estimate.
Upload your signed PPA, land lease, DISCOM approval, technical feasibility report and other required verification documents.
Our technical and legal team reviews your submission within 5–7 business days. Only verified projects go live for public investment.
Your project is listed on SunstoX. Retail investors buy cell tokens. Funds released to you at crowdfund completion. Monthly payouts automated.
Tap into a growing base of retail investors — individuals, parents, and corporates — looking to own solar assets. Diversify your funding sources beyond banks and PE funds.
The crowd-funded tranche replaces a portion of project debt. Lower your DSCR obligations and improve project financial ratios — without giving up equity.
SunstoX manages all investor KYC, UPI/RazorPay payments, lease agreements, monthly payout calculations, TDS deductions, and Form 16A — end to end.
Every investor gets a live dashboard showing their cells, monthly rental, CO₂ offset, and 25-year projected cashflows — building trust and reducing your support burden.
When local residents or institutions own cells in your project, they become advocates — not opponents. Build social licence with the communities your project serves.
Investors can trade their cells on the SunstoX Cell Exchange. This liquidity feature makes your project more attractive at fundraise — improving fill rate and speed.
Only projects that pass SunstoX's technical and legal review are listed for public investment. This protects retail investors and ensures every project on our platform meets the highest standards.
