The energy derived from the radiations of the sun is termed as solar energy. The generation of electricity with the help of solar energy is dependent upon specialized cells known as photovoltaic cells. Some of the many uses of solar energy include space heating and cooling aided by solar architecture, generation of electricity, solar water heating systems, and various other applications in homes, offices and large scale industries as well.

What are photovoltaic panels used for?
The greatest power density among all forms of renewable energy systems is that of solar power electrical generation. Also, it is extremely friendly to the environment in terms of the fact that it does not produce any emissions, toxic waste products or noise pollution either. It is for this reason that in contrast to other forms of power generation, solar power production is very eco-friendly. Photovoltaic panels are used to convert the energy from the sun into current electricity.
How do photovoltaic panels work?
These panels work on the photodiode effect and they can do this with the help of photovoltaic material. Photovoltaic cells are actually made of photovoltaic material which is sensitive to sunlight. This material is usually silicone based, but can also be made of copper alloys or alloys of other metals. Once the radiations from the sun shine on these PV panels, they get charged and then generate current electricity that can be used to power any appliance. The electricity that is produced by PV panels can also be stored for several hours, to be used at night. The only disadvantage is that basic photovoltaic solar panels can only supply uninterrupted electricity during the daytime because this mode of power generation is completely dependent upon the radiation of the sun for optimum functionality and store electricity just for a few hours. Regardless of this, the advantages of photovoltaic panels are many.
What are the advantages of photovoltaic panels?
There are many advantages of photovoltaic panels. Here are some of them:
The initial investment is recovered fast:
The installation of Photovoltaic panels only requires an initial heavy investment for their purchase and installation, after which the capital investment is recovered within no time owing to the countless benefits and durability of these panels. Like all equipments that have a lifetime durability, photovoltaic panels are also costly. You can also make DIY photovoltaic panels and save tremendously on the costs of installation. DIY panels do save on costs of installation but the recovery or payback period is also usually long for DIY systems. This does not immediately benefit people who have made small investments and require solar panels for small scale power production
Photovoltaic panels are literally maintenance free:
Another excellent advantage is the fact that these photovoltaic solar panels require little or no maintenance at all. As mentioned previously, their installation and purchasing are about the only costs that need the initial investment because the operation of the panels itself doesn’t cost much at all. They don’t require you to have any specialist knowledge in order to run them and they don’t require any heavy machines or generators to work either. If they are protected from extremes of weather, they can actually last a lifetime. Most supplies of photovoltaic panels give a 5-10 year warranty on the panels as well.
They don’t require grid stations:
They are also the ideal choice for secluded and remote areas where there is no electric supply grid station in the locality. The installation of solar panels can effectively and efficiently supply the area with maximum density electricity. The set up of the solar electric supply in such areas is also extremely economical. Solar power generation is at its peak during the season of peak sunlight and solar load, that is summer. During this season, obviously the demand for electricity is also at its peak owing to the need of air conditioning in homes and offices. In such a situation, connecting the solar electricity supply system to a utility electricity supply station minimizes and reduces the load on the latter considerably. This in turn aids in generating additional revenue.
Solar power is reliable:
There is no other source of power generation that is comparable to solar power generation in terms of reliability and durability. The efficiency of these panels decreases slightly after 20 years which means that it is better to install solar panels in your homes and offices instead of using the conventional, commercial electricity.
There are countless advantages of photovoltaic cells and the power produced by them with the help of solar energy. These advantages in brief are enlisted below:
- Photovoltaic cells have been tried, tested and are completely reliable.
- There is little or no requirement of maintenance of the PV cells because the system does not comprise of any moving parts.
- It is easy to install and does not require the usage of complicated, advanced tools.
- This is a modular system that can easily be adjusted to meet the requirement of the area.
- Produces much more energy than it consumes.
- Reduces your carbon footprint and allows you to contribute to the well being of the environment and the planet.
- Significantly cuts down on electricity bills and allows you to save a considerable amount of money.
