A cleaning system for a photovoltaic surface includes one or more of an electrostatic dust repellant, a vacuum device, and a compressed air spray device, powered by the photovoltaic array, and configured to function when the photovoltaic surface, including a photovoltaic array mounted on a base, is rotated from a first position with exposure to sunlight, to a second position, where the photovoltaic surface is almost parallel to the ground. The system includes a rotor to turn the base, and hence the photovoltaic surface, from first position to second position, rotating a front surface of the photovoltaic array by over 105 degrees. The cleaning device is housed in a half cylindrical box with an opening for exposure, and is positioned at an edge of the photovoltaic array when in its first position.

A hybrid photovoltaic thermal (PVT) system including flexible integration of spectral splitting optical filtration and thermal management utilities is described. An optical filtration (OF) channel is provided above a PV panel of the hybrid PVT system, wherein an OF fluid in the OF channel transmits a first light that is within a predefined spectral range and absorbs a second light that is outside the predefined spectral range. A cooling fluid (CF) channel is provided below the PV panel, wherein the CF channel contains a cooling fluid. A phase change material (PCM) layer is provided between the PV panel and the CF channel, wherein at least one of the OF fluid in the OF channel, the cooling fluid in the CF channel, or the PCM layer contains nanoparticles.

An indirect evaporative cooling system for cooling a space adjacent to or containing an ablution bay is described. The indirect evaporative cooling system includes a greywater source from the ablution bay and evaporative cooler apparatus located above the space to be cooled in a dome shaped housing. The evaporative cooler apparatus includes a wet channel, at least one spray nozzle, and a dry channel. The at least one spray nozzle is located at the top of the evaporative cooler apparatus and is fluidly connected to the greywater source and the wet channel. The wet channel is located directly above the dry channel. A first side of the dry channel is connected to a first opening with a fan and outside air.
