We use solar panels to generate electricity. This process can take place either in domestic or industrial purposes. The domestic solar panels can be used in generating electricity at home.
And in the industrial panel we use to generate electricity in mass. For this, engineers need to install an array of solar panels from a solar power station. Solar panels can be used to generate large amounts of electricity, and this process can take place both at solar and industrial scale. A key benefit of solar panels is that they can be used in providing electricity in the remote areas as well, provided there is enough solar energy at that place. This will help the people living there.
What are Solar Panels?
Solar energy is the energy that the sun gives to earth. Primarily as visible light and then later in electromagnetic radiations. Solar energy was developed nearly 100 years ago. Earlier the solar energy was used in generating steams, which was then used to drive machinery.
Edmond Becquerel discovered the photovoltaic effect, which allowed the conservation of sunlight solar electric energy. Sun’s energy is captured by the solar panel and they convert that light into electricity, which is then used to provide the power of electrical loads.
Such panels contain several individual solar cells which are composed of many layers of silicon, phosphorus and boron layers. Solar panels absorb the photons and electric current is produced in doing so.
The energy which is the result of this strikes the surface of solar panels allows electrons to be knocked out of their atomic orbits and releases into the electric field generated by the solar cell. This pulls the free electrons in the directional current. This whole process is known as the photoelectric effect.
For the necessary number of solar panels, an average home has more than enough roof area to produce enough solar electricity to supply the power needs
Solar Energy and Uses
Radiant light and heat from the sun is known as the solar energy.
To heat water, solar hot water systems use sunlight. In the middle geographical latitudes that are 40 degree North and 40 degree South, 60 to 70% domestic hot water use, with the water temperature at 60 degree celsius.
Evacuated heat collectors are the most common type of solar water heater, and glazed flat plate collectors are also considered as good solar water heaters.
The total installed capacity of solar hot water system was approx 154 thermal gigawatts as of 2007. China is the leader as in: 2006 it had deployment of 70 gigawatt and 210 gigawatt in 2020. Israel and Cyprus are also per capita leaders in usage of solar hot water systems.
Solar energy is not only used in heating water, but also in many other things in the house for cooking purposes, for process heating, water treatments, electricity production, heating cooling and ventilation etc.
Usage of Solar Panels in Agriculture
As we are aware of many uses of solar energy in different fields, One of those fields includes agricultural activities also.solar energy is the supplement of many farm energies. Solar energy is very helpful in agricultural activities as well. Solar energy is used in crop and grain drying and it’s one of the oldest and widely used techniques in agricultural activities.
The basic components of a solar dryer are screened drying trays or racks and solar collector, enclosure or shed. Solar energy is also used in space and water heating. Air and water heating requirements are often more in the dairy operations, modern poultry farms raise animals in enclosed buildings where it's very important to control temperature and air quality.
The next application is the greenhouse heating, the greenhouse depends on the sun for their needs, they rely on oil and gas heaters to maintain the temperature for the plants to grow in winters.
Uses of Solar Panels for Electricity

For the renewable energy available, the sun is the purest source. It can be used in many forms to help power our house and business. Solar powered photovoltaic panels convert the rays of sun into electricity. In this process electrons get excited in the silicon cell using the photons from sunlight. This electricity provides renewable energy.
The solar panels are placed at the top of the houses in most of the solar systems. There will be no shade on the panel side of an ideal site specially during 9 Am to 3 Pm. South facing installation provides the optimal potential for the system. While placement of the solar panels we should take care of a few of the factors like: trees should not be there near the house so that sunlight is not blocked and full productive use of solar panels are done.
In the solar panels even if one out of the 36 panels is covered then it will be very less productive. These are the few factors which are to be taken care of while placing a solar panel set.
