Abstract: In embodiments of a thermal and environmental control system an off-grid cold-storage facility has solar photovoltaic panels for producing electricity. A battery is in operable connection with the solar photovoltaic panels and configured to store the electricity produced by the solar photovoltaic panels. Cooling equipment is in operable connection to the battery and configured to regulate the temperature of the off-grid storage facility. Ventilation equipment is in operable connection to the battery to regulate air humidity and gas concentrations. A computer processor is provided at the off-grid storage facility and is in operable connection with the cooling equipment. The computer processor is configured to provide a regulating signal to the cooling equipment for optimizing battery usage, thermal setpoint, and environmental conditions. A cloud-based computing system is in operable communication to weather data and in operable communication to the computer processor.
