A few things I want to discuss with the community and get advice on.
No .1: I've decided to make a test system here at our location that is a stand-alone solar PV system connected to a router. The router is VPN enabled and also has cyber security using WEB SSL support, Firewall, DoS, spoofing prevention, User roles, Password management ICMP, Multicast and VPN filtering.
Basically the solar system will power itself from a battery bank and charge itself from PV panels. I have designed it in a way using worst-case scenarios for its location to have 99.8% uptime because of the battery backup. It will have a HTML5 login to its kWh production, (theoretical) solarcoin generation number since its birth and many other features.
I also think that if you can cost down these systems that are "mining" solarcoin's from the sun and sending information to the solarcoin foundation automatically for granting you are giving more economic utility and access to people anywhere on the planet that have access to the sun. That can't be a bad thing.
lfloorwalker, I want to encourage you to move forward with this and devote resources to it, because I think it's an awesome idea and could be one of the pivotal developments in SolarCoin as we move towards our goal of full automation of the granting process.
Thanks Freebird. If you go here to this link

After release and a bit of testing I will write a "Proof of concept" paper that I will publish online. I then want to get as much feedback as possible about some of corather's great comments regarding assigning "a unique hash" or "signing the output feature with a wallet signature" as these things would need to be discussed anyway.
As it is a stand-alone PV system, securing the battery (it is 30kg, 100Ah battery) and constantly proving that it is not being charged by any other means other than PV is a security issue to the SolarCoin blockchain. The system has a pyranometer (which measures input solar irradiance) and these precise measurement instruments are not cheap. That can be used to cross-reference the performance ratio of how many kWh is actually being generated by the system.
I currently estimate the system will be producing about 239.3 kWh per year (0.2393§/year). Possibly more but we have some large buildings blocking out medium horizon solar access. I am still completing our PVSYST models and adjusting loss co-efficients for those shading issues.
Thanks,
