During night times many companies install systems like molten salt storage that can store enough energy during daytime which can be used during night time. Due to efficiency and low-cost operation, nearly everywhere solar power plants are being planned. It is very efficient can also replace the fossils fuels that are used in the traditional power systems. Solar energy could be very cheap in the future as the crude oil prices are soaring.
Mini solar power has also got new found friends in the name of environmentalists as it does not emit polluting gases like carbon dioxides, carbon monoxide and other greenhouse gases as in the case of conventional power systems. In many rural areas in the least developed and developing the world there is a shortage of electricity to light up the homes, hospital and schools, in the places like above solar power system can light up lives of people. It can be utilized to run other equipment such as computers and refrigeration systems.
Another way to harvest solar power is by using photovoltaic cells. Photovoltaic cells are those that can be seen on the rooftops of private houses and commercial buildings and. These cells are covered with solar cells and it produces electricity when sunlight is illuminated on it. These panels use the technology of photoelectric effect. These photo panels absorb most sunlight when it falls on them directly so it has a mechanism that makes the sunlight to fall on them normally.
These mini portable solar power systems are fuelled by sun rays and do not emit greenhouse gases. They have a unique quality to store solar energy efficiently and dispatch it to the grid when the need arises even during cloudy days and also night.
