Calculator collaboration with Photon hmsistemas .com renewables to calculate the energy consumption of electrical apparatus, useful for isolated network systems for installations of solar photovoltaic or wind Plates consumption but also to save on electricity bills and know the La power you need. The most effective method for saving know how much you actually spend, monitor energy consumption of each appliance and electrical equipment that consumes each.

So we can get a rough estimate of consumption of electricity. the energy used by individual appliances are on the rating plate of all computers running electric current. For example, an LED bulb has the consumption of 5 W (A normal refrigerator about 90 w.)
