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).
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.
Solar power can be used for heat energyor converted into electric energy.
Renewable Energy When we use solar power, we don't use any of the Earth's resources like coal or oil. Solar power is also clean power that doesn't generate a lot of pollution.Since then, solar cells have been used on small items such as calculators.They have also been an important power source for spaceships and satellites.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.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.Starting in the 1990s the government has funded research and offered tax incentives to people using clean and renewable power such as solar energy.Scientists have made advances in the efficiency of the solar cell. One drawback is that the amount of sunshine in a specific place changes due to the time of day, the weather, and the time of the year.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.
