Entech Solar's ThermaVolt™ system is based on proprietary concentrating photovoltaic and thermal (CPVT) technology that simultaneously produces electricity and thermal energy. The ThermaVolt system's ability to convert the sunlight into two useful energy forms enables the highest energy efficiencies in the industry. 

Benefits:

• Highest Energy Efficiency Produces up to 3-4X as much energy as standalone PV systems, dramatically increasing customer's ROI.
• Low-Cost By concentrating the sun 20X, reduces silicon requirements by 95% compared to traditional PV systems.
• Reliable Production Performance Superior optical design of lens results in high error tolerance, enabling reliable, continuous production of energy even in the harshest environment.
• Produces Electricity and Thermal Energy Provides customer with a complete energy solution.
• Fixed Hedge Against Natural Gas and Electricity Eliminates customer’s vulnerability to increasing, volatile natural gas and electricity prices.
