But, where does that money come from? It's not the traditional model of Capitalism where someone creates wealth by taking a low value commodity and, by value-adding, makes it a high value item (iron ore and coal into steel or cotton into haute coiture), or by arbitrage, taking a commodity that is common in one place, transporting it to where it is rare and selling at a profit.
Money from solar panels can only come from two places ...
A) Government diverting taxpayer money from government spending back to private incentive payments to engineer behavior -- OR
B) Utilities raising rates to pass a portion of that money back to consumers who sell them power at wholesale rates.
Neither of those methods actually creates wealth. They are both wealth distribution for social engineering.
