Frequently Asked Questions

Delivery typically takes between 2 to 4 months from the order date. This can vary depending on the specific requirements and location of the installation. Our team works diligently to ensure your solar-powered cold storage unit is up and running as swiftly as possible.

Absolutely, we offer comprehensive support after purchase. This includes remote monitoring of the unit, customer service assistance for any queries, and a dedicated team for maintenance and technical support to ensure your system operates efficiently.

C-PACE (Commercial Property Assessed Clean Energy) is a financing tool for owners of commercial, industrial, multifamily, and agricultural properties. Non-profit organizations may be eligible as well. It is supported by many state and local governments. C-PACE allows a property owner to finance the cost of clean energy or other eligible energy efficiency improvements, paying the costs back over time with annual energy savings that exceed the annual assessment payment.
The list below is not a comprehensive list of C-PACE programs. If you do not see your local government listed below, search for C-PACE and your state or county. Many financial lenders specialize in C-PACE loans.

You could make your own Solar Powered Cold Storage unit. But we can give a compelling argument that a Do-it-Yourself unit won’t perform as well, won’t be as reliable, won’t look as good, will cost more, and will come with a lot of unexpected challenges that we’ve already figured out.

Our systems are designed to be as maintenance-free as possible, but we do provide software updates when necessary to enhance functionality and performance. These updates are made available remotely, ensuring your system is always running on the latest technology without any inconvenience.
