Solar Panels Plus LLC today released a new corn glycol solar thermal transfer solution that replaces traditional propylene glycol for many solar energy applications. The SPP corn glycol formula has many advantages over traditional propylene glycol used in solar heat transfer applications and has been designed specifically for use in solar thermal systems for applications such as solar water heating, solar heating and solar air conditioning systems.
Compared to traditional propylene glycol, SPP corn glycol provides more efficient heat transfer due to various factors including its lower surface tension, and has a solar-optimal PH of 8.2. This makes it an ideal heat transfer medium in solar thermal applications. Freeze points, viscosity and other key metrics are about the same or better than conventional propylene glycol. Another of the major benefits of SPP corn glycol over propylene glycol is the fact it is a biodegradable and a completely renewable product, making "green" solar thermal applications even "greener".
The SPP corn glycol solution will begin shipping on September 2nd, 2008. It is available in 5 gallon containers, 55 gallon drums, and 265 gallon totes. The SPP corn glycol will be sold through the SPP national dealer network, and for areas without SPP dealers it will be available for sale directly through the SPP website at http://www.solarpanelsplus.com.
