PV Energy HERSIC Int.

Today, solar-generated electricity serves people living in the most isolated spots on earth as well as in the centre of our biggest cities. First used in the space program, photovoltaic (PV) systems are now used to generate electricity to pump water, light up the night, activate switches, charge batteries, supply the electric utility grid, and more. Whether you are a homeowner, farmer, planner, architect, or just someone who pays electric utility bills, PV may already touch your life in some way.

Benefits of Solar LED Lights

Systems using several types of electrical generation combine the advantages of each. Engine generators can produce electricity anytime. Thus, they provide an excellent backup for the PV modules, which produce power only during daylight hours, when power is needed at night or on cloudy days. On the other hand, PV operates quietly and inexpensively, and it does not pollute. Using PV and generators together can also reduce the initial cost of the system. If no other form of generation is available, the PV array and the battery storage must be large enough to supply night time electrical needs.

Including generators makes designing PV systems more complex, but they are still easy to operate. In fact, modern electronic controllers allow such systems to operate automatically. Controllers can be set to automatically switch generators, to supply ac or dc loads, or do some of each. In addition to engine generators, electricity from wind generators, small hydro plants, and any other source of electrical energy can be added to make a larger hybrid power system.

Hybrid Power Systems

Hybrid systems combine a number of electricity production and storage pieces to meet the energy demand of a given facility or community. In addition to PV, engine generators, wind generators, small hydro plants, and any other source of electrical energy can be added as needed to meet energy demands and fit the local geographical and temporal characteristics. These systems are ideal for remote applications such as communications stations, military installations, and rural villages.

Essential to developing a hybrid electric system is knowing the energy demand to be met and the resources available. Energy planners therefore must study the solar energy, wind, and other potential resources at a certain location, in addition to the planned energy use. This will allow them to design a hybrid system that best meets the demands of the facility or community.
