A solar water pasteurizer has a water jug removably disposed in a solar box with insulation and a solar window. The water jug has a lid to close an aperture in the solar box and a handle thermally isolated from the water jug to facilitate handling of the water jug with heated water. Multiple water jugs can be swapped in and out of the solar box. The solar box also has a thermal mass to preserve some heat in the solar box.

The present invention provides a boltless module mounting system and a method of installing a boltless module. The system includes at least one module frame containing a module laminate, at least one support structure having support rails, and multiple boltless mounting components. The mounting components attach the module frame to the support rails. The present invention also provides a boltless module mounting system including at least one module having posts and at least one support structure with support rails. The support rails have receiving slots with a receiving hole and two or more slide slots. The posts interlock with the receiving slots. The method includes aligning multiple boltless connectors, lowering a boltless module frame onto a support structure, and sliding the frame to interlock the boltless connectors.

A plant for the accumulation and transfer of thermal energy, which plant has an accumulation device of the kind with a bed of fluidizable solid particles. The plant further has for each accumulation device: electric resistor means arranged within the casing and thermally connected with the bed of particles, which electric resistors are configured for transmitting thermal energy generated by Joule effect to the particles and they are fed by exceeding electric energy from wind or photovoltaic source; and heat exchange means, also thermally connected with the bed of particles and which can be selectively actuated to receive thermal energy therefrom,
the overall configuration being such that the thermal energy is transferred from the resistor means to the fluidizable solid particles of the bed and from the fluidizable solid particles to the heat exchange means.

Embodiments herein provide a solar appliance. The solar appliance comprises an outer shell and an inner shell having at least one platform for placing one or more containers. Each of the inner shell and the outer shell are made of a preselected material. The inner shell is configured for receiving the sunlight for heating content inside the one or more containers. The solar appliance further comprises a gap provision provided between the outer shell and the inner shell for allowing a circulation of a medium. The medium insulates the inner shell and conserves the heat inside the inner shell.
