There's a local cooperative here in Germany (named Energiegewinner if you want to look them up) that acts as a facilitator for this. They're approaching this from all directions:
1. You can buy power from them at normal power company retail rates. You get power from the grid that they buy at wholesale rates, profits go into building out solar.
2. You can become a member by buying any number of shares. Capital gets used to fund solar buildout, profits go back to each shareholder. Each shareholder has one vote regardless of the number of shares they own to prevent buyouts.
3. You can rent them your roof space. You get paid, other people put cells on. You get reduced-rate power from your own roof's cells, excess goes to grid.
4. You can buy solar panels and rent them to the cooperative. For every large installation they make, they'll ask people to buy panels. You get paid a part of what the panels produce for 20 years, at a guaranteed rate, and at market rate after that.
5. You can have them act as a solar installer and set up panels on your property for your own use. They'll buy excess production and sell you grid power when you have insufficient production. In this case you finance the install yourself.
They have excellent economies of scale from standardizing installs and they allow people with capital but no roof space to connect with people with no capital but usable roof space. Because retail rates for power are high and they've centralized installation costs they're making an okay profit. Maybe something like this can work where you are?
