Once you have made the capital investment for your solar panel, the electricity it generates is basically free. In economics terms, the marginal cost of an extra kW/h consumed is zero. This is different from the current economy where each marginal kW/h of electricity consumed costs the same price.
It's perhaps a bit of an oversimplification for OP to say "Energy won't be subject to market forces", since there will still be a market for solar panels. But the more that solar energy production is decentralized and commoditized, the less there will be a market for the generated energy itself.
OP said "Zero marginal cost", not "Zero cost". https://en.wikipedia.org/wiki/Marginal_cost
