Modern-day buildings have become the third-largest consumer of energy, after industry and agriculture, energy consumption in contributes up to 40% total use developed countries [...]

In today’s and future’s electrical power grid system, regenerative energy sources like photovoltaic (PV) power systems consisting of PV panels and grid-connected inverters are very popular in domestic as well as in commercial power plants. High competitive pressure among PV power system providers due to cut inverter’s costs can be observed. Therefore different technical approaches have to be ev...

it is expected that residential units may replace   traditional heat and power production systems with cogeneration ones. among the different cogeneration systems, fuel cell based systems are a suitable choice due to their high efficiency, high power density, low emission and low noise. in this paper, a cogeneration system based on solid oxide fuel cells is examined. the system, including the f...

Photovoltaic (PV) panels get hot in the sun. This decreases the operating efficiency through various means. Several approaches have been proven effective at cooling panels. Green Roofs are thermally cool, outperforming even white roofs over their life. On a hot summer day, a green roof can be 30◦C cooler than a typical roof, potentially improving the efficiency of a photovoltaic (PV) panel by a...

In Algeria, there are many isolated sites which are not yet connected to the conventional electrical grid and face severe problems of water for domestic consumption and irrigation purposes. There are some photovoltaic water pumping system (PVWPS) which are situated in remote areas. Due to the high cost of setting up and maintaining a large number of PVWPS, we present in this project a methodolo...
