When an electric circuit is formed across the top and the bottom of the cell, current will flow, powering electrical equipment.
It takes a lot of solar cells to power a building or a home.
It is not only free but unlike other sources of energy; it also limits the amount of pollution caused to the environment.
When building our houses the goal according to David Johnston and Scott Gibson is to create a house that consumes at least fifty-two percent less energy than one built conventionally with a corresponding reduction in the heating and the cooling cost.(Johnston, Gibson 252)This can be done through use of solar panels, solar water systems and photovoltaic.
They are becoming more popular for buildings and homes as they become more efficient.
One nice thing about solar cells is that they can be placed on the roof of a building or home, not taking up any extra space. Solar cells convert the energy of photons from the sun into electricity.In this case, a number of solar cells are connected into a large array of cells that can produce more total energy.History of Solar Power The photovoltaic cell was invented in 1954 by researchers at Bell Labs.Their variations come from the mechanisms that they use to pump water in the circulation.A passive heater usually has a tank that plays the role of both the storage and the solar collector.The above all rely on one source: solar energy which comes In the case of cold climatic conditions there might not be enough sunlight to provide a source of heat and in this case a person may consider using an electric pump for heating.“The amount of electricity required is however minimal.”(Johnston, Gibson 250) There are different types of solar water systems, passive and active solar water systems.Solar Power for Heat Solar power can be used for heating up homes and other buildings. This is when there are no mechanical components used to move the heat around.Passive heating helps to keep houses warm in the winter, to heat up swimming pools, and even makes our car warm when we park it outside (which is nice in the winter, but not so much on a hot summer day).Solar energy can be used in different ways during the construction of houses in order to conserve energy.Solar energy comes as a gift of nature and this makes it even more economical to use in our buildings.
