As far as I can understand:
People who generate solar power have to send in proof of generation as provided by energy companies paying feed in tariff. Humans then allocate SLR.
Obviously this doesn't achieve anything, so the penultimate idea is for PV inverters to report electronically what they generate directly to the SLR network which will automatically allocate SLR. The energy companies, who are obliged to pay the FIT, will instead of paying it in inflationary currency, will have to buy SLR on the market in order to meet their obligations.
This still doesn't achieve much if the only thing people who generate from PV can do with their SLR except sell them on the market. So the ultimate will be for solar PV equipment to be on sale priced directly in SLR. This will cause the generation of renewable electricity to be self expanding to the point when all electrical energy comes from this source.
On the basis that all renewable energy originates from the sun, I personally believe that wind, wave and hydro power should be included, but I don't think this is planned at present.
I suspect that I have got a lot of this wrong, therefore ask people to post corrections to this thread.
