The Ice Cub, Ice Energy's hybrid air-conditioning and thermal energy storage system, is now available for purchase by California homeowners and homebuilders.
The solar PV-compatible unit replaces a conventional 5-ton outdoor condensing unit and is designed to work seamlessly with home HVAC systems. The Ice Cub functions like a typical condensing unit, but it also makes ice to store up to four hours' worth of cooling.
"For homes with solar PV," Ice Energy says, "a full tank of ice can be made and stored during the day, using what would otherwise be surplus solar generation."
The Ice Cub retails for $15,000. But Ice Energy says two government incentives potentially reduce the cost of purchase and installation to below that of a conventional air conditioning system. The Ice Cub qualifies for California’s Self-Generation Incentive Program rebate and, for homes with solar PV, the federal Solar Investment Tax Credit. Ice Energy says the payback period for an Ice Cub installed in a California home with solar PV is less than one year.
The company, based in Southern California, says it is in the early stages of recruiting regional project partners such as homebuilders and HVAC installers.
“Conventional AC units in California have become increasingly expensive to operate as the state’s new time-of-use rates take effect,” said Joseph Draper, executive chairman of Ice Energy. “The Ice Cub, by contrast, reduces consumption of expensive electricity and can save homeowners as much as $1,500 a year on their utility bill. The smart, energy-efficient Ice Cub is a true consumer product with real potential to render conventional home AC units obsolete. We are very excited to make it available for immediate delivery to homeowners and builders here in California.”https://www.solarpowerworldonline.com/2018/10/ice-energys-hybrid-air-conditioning-and-energy-storage-system-qualifies-for-itc-with-solar/
