Off-grid solar · public record
Solar power where the sun rises and the grid never arrives
Sunrova funds solar systems for schools, health clinics and village water pumps, and publishes every system's daily output, so anyone can see what was built and whether it still works.
The problem
600 million people without electricity, under some of the strongest sun on Earth
The money thins out
A donation passes through several intermediaries before any of it reaches a roof.
Systems stop working
Panels go up, and a few years later many no longer produce, because maintenance was never funded or checked.
No one can see the result
The people who paid rarely learn whether the system works today. The public almost never does.
So trust is missing
Sunrova's answer is not a promise. It is a record anyone can check, every day.
How it works
From a meter on a school roof to a public record
A sponsor funds a named system. 88% goes to the installation; the 12% operating fee is fixed and public.
A vetted local partner installs and maintains it at a school, clinic or water pump.
The system's meter reports hourly energy. Each finished day becomes one signed data file, stored on Filecoin.
The day's total and the file's fingerprint are written to the Celo blockchain. Anyone can download the file and check it.
Trust
What if we are wrong, or lie?
Sunrova runs the service that publishes the data, so it is the weakest link. The design does not ask you to trust it blindly.
- Open raw data. Every day's file is public, and its fingerprint on-chain means it cannot be quietly replaced.
- Device signatures. Where the controller can sign its own readings, the signature is in the file. Invented numbers would not match.
- Physical limits. A system cannot produce more than its capacity times that day's sunlight, from satellite data. Days above it are flagged.
- Independent visits. Once a year someone independent of Sunrova photographs the meter and compares it with the on-chain total.
- Silence is recorded. A day with no output, or no data, is published as exactly that.
Model
How Sunrova sustains itself
88% of every contribution goes to installations. 12% pays for operations, monitoring and maintenance, fixed in the contract that receives contributions.
SRVA supply is fixed at 100,000,000. 70% public, 15% founder (nothing for a year, then vested to year four), 15% project treasury in a multi-signature wallet.
Companies fund named installations and get a public meter page and an impact report for their sustainability reporting.
Fees on transfer, new tokens after launch, dividends, revenue share. None of them exist.
Roadmap
One system that works, before anything larger
- NowDesign, contracts and oracle written and tested. Name and domain secured.
- TestnetContracts on the Celo testnet; the oracle runs on recorded meter data; first public page.
- PilotOne real system at one school or clinic, proposed in Kenya, with a field partner. 30 days of daily reports.
- ReviewData gaps, plausibility flags, cost. Then a decision on the token and any sale.
- GrowthMore systems, more sponsors, a second country.

Install, sponsor, or advise?
You install and maintain off-grid solar for schools and clinics, ideally with remote monitoring.
Your company funds a named system and gets a public meter page and an impact report.
You know token regulation, energy access or impact verification, and want to help get it right.
