For what it is worth, I am a volunteer who helped do the research on the carbon footprint model for SolarCoin and the marginal utility econ model for bit-coin.
The OCA (open currency association) behind SolarCoin (SLR) has some serious finance and environmental people behind it.
I am a volunteer helping out that team.

I am happy to answer questions about the solar energy component, solar etc.or basics about the coin mechanics and generator pool that holds the pre-mine. No SLR can circulate from that pool until the OCA is set-up and charter agreed to by community members. Then the generator pool can only be allocated to those submitting proof of solar energy production ( a physical proof of work).
The large pre-mine is meant for 40 years of distribution to solar energy producers with verified claims to "proof of work" such as SRECs in the US at the rate of 1 SLR/ 1 MWh production. the team is at work arranging deals in N.America, MENA, Europe and Asia.
There are some bids on twitter for it. (not mine)
The OCA put out a tool to generate bid/ask hash tag offers for SolarCoin, Bitcoin and Litecoin.
