摘要： Solar collection and storage module systems as building blocks are provided to build walls or shingles of buildings to transform any buildings into stabilized power generation stations and tie to power grid to form power grid-interactive efficient buildings. The solar collection and storage module system comprises a hybrid photovoltaic and thermal panel, thermoelectric modules, thermal storage package, control system, and battery storage. The incident sunlight is partially converted into electricity directly by the photovoltaic part of the system directly, and rest part is transformed into heat which is extracted, boosted to high temperature, and stored into the thermal storage package by the thermoelectric modules operating in cooler mode at this movement. At night or in cloudy days, the stored heat flow through the thermoelectric modules, which are switched to generator mode by the control system, generating electricity. In the module system, the cogenerated heat is stored in thermal energy format and outputted in electrical energy format; the total conversion efficiency of the module system is significantly improved. When the module systems are used as wall modules or shingles to build buildings, the encapsulation properties of the buildings are substantially improved.

摘要： An inflatable non-imaging solar concentrator based concentrating solar thermal and photovoltaic system powered water desalination system comprises a concentrating electricity and heat cogeneration subsystem, a battery storage subsystem, a thermal storage subsystem with electric heater, a thermal power regeneration subsystem, and a water distillation system with electric heater. The inflatable non-imaging solar concentrator makes the concentrating system substantially low cost, and the hybrid solar thermal and photovoltaic panels used to construct the cogeneration receiver make the system ultra-high efficient. The cogenerated thermal energy is stored in a thermal storage and the cogenerated electric energy is stored in a battery storage to heat the stored thermal energy to pre-set high temperature for thermal power regeneration. The thermal energy after thermal power generation is used to desalinize water with assistance of electric heater powered by the stored electricity. An extra conventional photovoltaic system is added to compensate the concentrating hybrid solar thermal and photovoltaic system.

摘要： An mobile solar powered EV charging station consists of an inflatable solar concentrator based hybrid solar thermal and photovoltaic subsystem with thermoelectric activated thermal storage to store thermal storage and regenerate electric power; a battery bank subsystem to store the cogenerated electric energy from the hybrid solar thermal and photovoltaic subsystem; an electric driving subsystem to make the entire system mobile; and a control subsystem to coordinate all of the subsystem to work. The mobile EV charging station is not only able to generate electric power locally to charge EVs, but also able to transport power from solar powered EV changing station network and power grid to the sites where EVs are located.

摘要： A non-tracking non-imaging solar concentrator system, which is able to concentrate both beam light and diffuse light with high concentration ratio, comprises a Compound Parabolic Concentrator (CPC) and a domed divergent Fresnel lens. The system is configured by mounting the domed divergent Fresnel lens on the top of CPC, or making a chamber with its bottom thin transparent wall shaped into CPC and its top thin transparent wall shaped into domed divergent Fresnel lens to form a bulb-like close structure solar concentrator. Wherein, the non-image CPC with small acceptance half-angle is used to concentrate both beam light and diffuse light with high concentration ratio, and the domed divergent Fresnel lens is used to refract the incident light to enlarge the acceptance angle of CPC, and therefore to realize stationary concentration. The bulb-like close structure concentrators are stacked together to realize arbitrary high concentration ratio of solar concentrator.

摘要： A portable floating sea water desalination system is presented to realize ultra-high efficiency and extremely low cost water purification. The disclosed system comprises an inflatable non-imaging solar concentrator based compact desalinator subsystem, a photovoltaic powered distillation subsystem, and an inflatable rubber boat system. The inflatable non-imaging solar concentrator concentrates both beam light and diffuse light into an envelope type evaporator to evaporate the brine water to realize extremely low cost. A nano materials absorber is incorporated into the evaporator to realize ultra-high efficiency. A portion of the heated brine water contained in the evaporator is circulated to the photovoltaic powered distillation subsystem for further evaporation. Both of the subsystems above are mounted on the inflatable rubber boat subsystem for portability.

摘要： A solar powered electric vehicle comprising a conventional electric vehicle and an inflatable non-imaging solar concentrator based concentrating photovoltaic system trailer. The trailer is super-light and able to charge the front electric vehicle when it is moving. The inflatable non-imaging solar concentrator can concentrate both beam light and diffuse light. The inflatable non-imaging solar concentrator dramatically reduces the area of the semiconductor receiver of the concentrating photovoltaic system and significantly reduces its cost. The trailer is made foldable by hanging multiple trailer units mounted with the inflatable non-imaging solar concentrator based concentrating photovoltaic systems.

摘要： An extremely low cost solar concentrator made of membranes or films is inflated into a Compound Parabolic Concentrator (CPC) a non-image concentrator. The portion of the inflatable concentrator, which is shaped into a CPC concentrator, is formed with reflective membranes or films, and the portions of the inflatable concentrator on the top of CPC and on the bottom of the concentrator are made of clear membranes or films. The incident light including parallel rays of light and diffuse light, as long as falling into the half acceptance angle of the CPC, will be concentrated to the bottom exit aperture of the CPC. Therefore, this type concentrator reduces the requirement to the accuracy of tracking for concentration. In addition, this type of concentrator demonstrates more tolerance to shape distortion for concentration than imaging system.

摘要： An inflatable non-imaging non-tracking solar concentrator based Concentrating Photovoltaic (CPV) system powered airship consists of a conventional airship with an upper transparent cover and an array of inflatable non-imaging non-tracking concentrator based CPV modules. Where in, the inflatable non-imaging non-tracking solar concentrators are inflated with helium or hydrogen and fused into the structure of the airship to generate lifting force and concentrate sunlight to supply power simultaneously. The introduction of the CPV system into the airship dramatically reduces the cost and significantly raises conversion efficiency of the photovoltaic system without adding any extra weight to the airship. The expansion of the airship will both increase the buoyant force and power supply.
