Why? A few reasons:
I’d argue too many people are looking at solar pv and it’s becoming more competitive. Just look at how many solar pv installers there are in Massachusetts, there’s around 50. This number is increasing as more and more tradespeople and leasing companies are getting into the game. Given the Massachusetts SREC market is structured to create 30% growth every year, it’s clear why so many companies are focusing on this.
Solar thermal can be used for space heating, and solar cooling technology is coming online. These applications will make it extremely attractive.
In Massachusetts, solar thermal receives great incentives, which only improve already good financials. For example, in Massachusetts you can receive up to $10k for a site evaluation and another $25k (for private) or $30k (for public) – see details under construction grants here – rebate for the installation, given the client meets a few criteria.
I think there are 7 national trends happening that are really favorable to solar thermal. Read the 7 Ways The Solar Thermal Industry is Laying the Foundation for Solid Growth, to read more including current bottlenecks in the industry.
I’m no genius, but if I wanted to make some cash in solar thermal, here is what I would do.
