I’m always on the hunt for the new products, trends and technologies that are decreasing the cost of clean energy solutions. In the past few years the innovation has mainly come from decreasing the cost of the large system components (modules, heatpumps, etc) and building up a trained labor force. When I started installing solar it took a four man crew four to five days to install the average 5kw system for a home. As my residential career was wrapping up, that same four man crew could do it in a little less then two days. 50% lower labor costs. We all know the same story has been true with module prices. But now that we have more trained workforce and the hard costs are decreasing rapidly, where can we looking to further decrease costs?
