When the room temperature drops below the set point on the thermostat, a circulating air pump turns on and extract the solar heat until the room temperature air reaches the desired set temperature. Once room temperature reaches the set point in the thermostat, the air circulation pump turns off.

A novel method is described for water heating using stored solar heat. Solar heat is stored in an insulated tank by using scrap and inexpensive heat absorbing or heat storing materials. Stored solar heat can then be used to heat water in a storage tank by extracting the solar heat using an antifreeze liquid which in turn heat cold water in the water tank. Water temperature in the storage tank is controlled by a thermostat. When the water temperature drops below the set point on the thermostat, a circulating pump turns on and pump the cold water until it reaches the desired set temperature. Once it reaches the set point in the thermostat, the water circulation pump turns off.

The present application discloses a method and an apparatus for solar power generation through gas volumetric heat absorption based on characteristic absorption spectrum. A radiation energy conversion device absorbs concentrated solar radiation and converts radiation energy into thermal energy; the thermal energy is transferred to the other side of the radiation energy conversion device and then is converted into radiation energy; and the energy is transferred in a receiver cavity. The working gas from the outlet of a recuperator flows into the receiver cavity and absorbs the radiation energy. The heated working gas with high temperature flows into a turbine, doing shaft work through expansion. The expanded working gas flows through the recuperator to exchange heat. The working gas flows into a cooler, a compressor and the recuperator in sequence, and then flows into a receiver cavity to be heated volumetrically, completing a thermal power cycle.

A spectrum-splitting concentrator photovoltaic (CPV) module utilizes direct fluid cooling of photovoltaic cells in which an array of photovoltaic cells is fully immersed in a flowing heat transfer fluid. Specifically, at least a portion of both the front face and the rear face of each photovoltaic cell comes into direct contact with heat transfer fluid, thereby enhancing coupling of waste heat out of the photovoltaic cells and into the heat transfer fluid. The CPV module is designed to maximize transmission of infrared light not absorbed by the photovoltaic cells, and therefore may be combined with a thermal receiver that captures the transmitted infrared light as part of a hybrid concentrator photovoltaic-thermal system.
