When one thinks of electronics and solar, one inevitably studies photovoltaic cells or panels. Analogies to processes used in the semiconductor and PCB industry abound. In addition, the inverter, key to transforming the raw energy into grid-compatible electricity, is a PCB assembly of significance.

But there is another side to solar...thermal solar panels where energy is extracted through heat exchange. The typical end result is hot water as opposed to electricity (PV). Costs are lower, payback is faster. Key players in the Americas include SunEarth, AET and Soletrol (Brazil).

Although there is less "electronics-like" manufacturing synergy, there is some significant electronic content. Indeed, a tpyical system consists of a flat plate collector, a hot water reservoir, and a unique electronic controller that activates the flow of the transfer fluid, based on a differential temperature measurement. Key players on the controller front are pretty much all European (Resol, Steca).

I have just completed a technology and marketing review of this segment of the solar industry and I find that there are opportunities for a North American companies on the design and manufacturing of controllers that are better suited to the NA market.

Those interested in learning more about my findings can contact me to discuss.
