I think you underestimate the efficacy and resourcefulness of the private enterprise. People are usually rewarded (a lot) when they find new markets, and in the modern economy, they do. There is no reason to expect they would stop doing that if we would abolish the stock market. I’m sure that the majority of all businesses are able to fund their own ventures (including solar panel manufacturers), if they don’t have the savings, there are also loans, government (and community) support, etc. I think your overestimate of the value (or rather the necessity) of the stock market stems from big, expensive, and risky ventures. Perhaps you are right and those would suffer if the stock market would suddenly collapse on it self. However like I said previously, I think you underestimate the resourcefulness of the private enterprise. In a world where there are no stocks, and a company wants to venture in a risky and expensive project, that nobody wants to loan for (not even the government) perhaps they would find a way to scale down the project, start earning profits (or demonstrate how the profits will come as the project is scaled up). Perhaps some loan agency will specialize in large risky loans (at a higher price), and perhaps we will (god forbids) re-invent the stock market. If I am wrong and I overestimate the resourcefulness of the private enterprise. Then the government can always kick in and fund the deployment of those solar panels. After all we do need them, and there is no risk for the government (well the risk is the other direction of letting those solar panels go undeployed and risk a runaway climate disaster; hence the green new deal).
