BunkerShares has developed a technology that can be applied to this.
Create a UIA that will be sold at a set rate that will cover infrastructure costs, consulting.. essentially the COGS.
Sell it.. however you like to as a 'voucher' to business owners or whom ever would like to buy 'solar tokens'
The solar token holder can then sell it on the market for however much return they want.
The money that comes in from the grid from the entire infrastructure in USD converts to bitUSD.
The lowest solar tokens get bought up first while the higher priced ones will have to wait.
Each solar holder will compete on their rate of returns and how fast they come with other holders. Those willing to get lower returns and get out faster will get sold faster while those in it for higher returns over a longer period will set a higher rate.
This can all be automated and be transparent with buyers being able to view the buy history through a webwallet explorer that allows them to see/audit everything coming out.
This is what I made that I call SAFE.. Synchronized Asset Futures Engine. It's what will power BunkerShares selling market.
I would run one of these in each incentive market you mentioned.
This gives a start and end to the lifecycle of the asset that will eventually go out of the market. What happens to the money after that? If there is any lifecycle left in it I would suggest that it somehow flows into a pool UIA that would invest in future projects perhaps... or be put towards R&D to further solar efficiencies etc.
I highly recommend picking up 1 billion BunkerShares so that you can experience first hand how SAFE investing works.
Hey.. the Bunker is prime for a solar project too... we have several acres of parking lot that could use solar covered shelter.
Note that this would avoid any regulation complications. You are just selling coupons, and holders are redeeming them.
Hope this helped in some way.
