Yes, and also, the solar industry is not necessarily low margin since there is a fixed point to compete against (if your tech is protected with patents enough) - which is the cost of energy from oil/nuclear or other sources; and those are fairly static. If a watt costs 2$, you can charge 10% less and sell as much as you can produce; regardless of production costs. So if you could produce for 1.5$ you could have double digit margins, and the cheaper you make your process, the more margin.
