About solar thermal power

Solar thermal power is the most cost effective solar power solution.  Zonbak solar thermal panels at 85% efficiency deliver 5X more solar energy per square foot than your typical photovoltaic panel. Our multi-patented design breaks new barriers in watts of energy produced versus dollars you spend.

Heating and hot water consume on average 46% of all utility bills.   Instead of spending between $15,000 to $40,000 per installation, a Zonbak system can greatly reduce your energy (heating) bills for under $2,000.
