Multiple Solar Hot Water Tanks – Does It Make Sense?
Every solar installer has their own unique approach to designing systems. A big part of this is determining how much energy will be produced by the system once it is installed. Many solar pros are unaware of the F-Chart methodology and its accuracy in determining solar output. I address this in my article on analysis methods.
The author of a recent online article determines his solar output by using the manufacturer’s rated collector output. This is much less accurate since the collectors are rated under very controlled conditions that usually are nothing like the actual demand parameters of the client’s facility.
Another curiosity to me is the fact that so many solar pros recommend using multiple solar hot water tanks in their commercial installations. This is asking for trouble. Apparently there is insufficient data in the marketplace regarding well-made commercial solar hot water tanks large enough to get the job done alone.
As more Fluid Handling Systems make it out the door, this knowledge gap will be filled…
