Project 4 – Pi0/2

Solar Powered Node connected to ROKAS OS on Raspberry Pi 2 – Completed

Project has begun at Solcrypto in February 2016. Funded by Sunpulse K.K./Solcrypto

Scope of Work: The small DC datalogger connects to a small Solar Home System (SHS), which are prevalent in developing countries, and records the kWh produced. This is then sent as PHP script to the Solcrypto login platform. Then the kWh is associated with a user account, this information is then collated and sent to the SolarCoin Foundation API in batches to claim the SolarCoin for the users.

Skill level: Blockchain/Dev (low), Solar (medium), Monitoring Hardware (High but led by Solcrypto expertise).

Goals: We need more SolarCoin nodes globally that are easy to setup. This problem is solved with ROKAS. These people have written a wallet OS system that runs on any Raspberry Pi 2.

Background: ElectriCChain is a Blockchain As a Service (BAaS) and we are using the SolarCoin blockchain but are actually open and technology agnostic for collaboration and development with other blockchains such as Ethereum, lisk etc. The main aim of ElectriCChain is to build the largest open scientific solar monitoring system by connecting solar monitoring devices (data loggers, inverters, Raspberry Pi nodes) with the SolarCoin blockchain. We are always on the search for talented developers who can help us with this mission. The “new-language-layer” project is also important as it aims to facilitate building a cross- blockchain language for synchronization between blockchains. As JFK said when he gave a speech about sending a man to the moon,  “We choose to go to the moon in this decade and do the other things, not because they are easy, but because they are hard.” JFK and also a good philosophy that some of us like is “There is no success, no failure, only make. Keep making.” Unknown

Estimated Budget: Undisclosed or SolarCoin Equivalent plus 120 hours testing and debugging work. Currently we have burnt through 2BTC and 15 hours of engineer time.

End Dream: Decentralized where small remote solar powered communities are self-funded by the sun. They can then generate supplemental income in SolarCoin and trade this for other goods and services. Smart contracts for insurance, micro-financing and micro-banking Dapps could also be built for these currently estimated 1 billion people.

Timeline: Before June 2016 target – Project completed and merged with project 3 (Pi3 dynamic granting) – an introduction to dynamic grant can be seen here:

This script is available to all monitoring and solar inverter/datalogger companies as open-source. Please reach out to ElectriCChain.

Solar Owners interested in using the technology and being granted SolarCoins to the SolarCoin Blockchain on a live basis, hence contributing as a Node to the SolarCoin Network can do so with the following Instruction Manual and connect their Pi3: (for enphase inverters)

and (instructions inside)

Current research is now being done over other inverter manufacturers and with pruning the Blockchain for Pi0 (5USD piece of equipment) application.
