HyPV is a solar PV system with energy storage. HyPV operates at stand-alone PV mode or grid mode by switching technique using ATS (automatic transfer switch) and does not feed solar power into grid. It operates at PV mode when solar PV power generation or battery storage is high enough and switches to grid mode when battery storage is low.

The goal of the current study is to compare the performance of the two typical solar stills namely, pentagonal pyramid still (PPy) and tubular (Tub) still having similar absorbing area.Further, an attempt is made to improve the freshwater yield of the stills by coupling them with a latent heat based thermal energy storage (LHTES) medium.The low-cost crude wax had …
Charles Elton (UK Ecologist) – Image Source – Link. In 1927, the concept of ecological pyramid [1] was first proposed by English Ecologist named Charles Elton (1900-1991) (thus, they are also known as Eltonian pyramids). An ecological pyramid is basically a pyramidal depiction of the number of organisms, biomass, and productivity in each trophic level in an …

In the pyramid of energy, the energy moves in only one direction and decreases at each succeeding trophic level. The total energy transfer from one trophic level to the next is, in general, only about ten percent or less. This is called the energy conversion efficiency. Organisms fail to capture and eat all the food available at the trophic ...
