Echo and Echo+ are complete solar energy solutions. While basic solar systems only provide electricity, Echo and Echo+ provide electric and thermal energy. Echo provides electricity and hot water, while Echo+ provides electricity, hot water, solar home heating, and solar home cooling.

Echo solar systems capture more of the sun's energy and generate more energy, so you save more on your utility bills. All Echo solar systems include Performance Monitoring and Remote Thermostat Control, available free of charge through this iPhone application.

Use this app to monitor and control your Echo or Echo+ solar system as well as the fresh air ventilation in your home (where this feature is installed). Current electrical and thermal output of the system and an “at a glance” animation show current system performance and operating conditions.
