Solar PV modules are created for electricity generation through sunlight. They are extremely effective, durable, and simple in nature. You just have to set them up in the presence of sun, in order to charge all the batteries, produce utility grid energy, and operate your appliances and equipments. A solar generator is used in the system, which collects solar energy with the help of photovoltaic effect.
Whenever a photovoltaic cell is hit with the sunlight, photons and their energy are absorbed and subsequently transferred to the electrons present inside the semiconductors. This absorbed energy assists the electrons in escaping their original positions and create a current throughout the circuit with other escaped electrons.
Components used in the configuration of solar systems
There are several important components involved in the arrangement of the insides of any solar PV system. The very first components are the solar PV panels, which are not only the most essential part of the system, but also constitute its highest expense. The performance of your system is solely determined by the settlement and mounting of these panels.
Mounting equipments are also an important part of solar systems because of the requirement of maximum sunlight for optimum electricity production. You have to mount the panels by using equipments in such a way that all-out amount of sunlight is obtained in a year. Your equipments must mount the whole system so effectively that it stays in its position for more than 25 years.
High current inverters with low voltage are also required within the system for creating a power, which shares high compatibility with the grid. They must be reliable and durable so make sure that you choose a quality product. Tracking mounts should be used for providing movement to the solar PV panels so that they can acquire sunlight throughout the day at any direction. Don’t forget to disconnect switches in the system for safety purposes.
Other important components of the solar PV systems are utility meters, connections for fuse box and wirings.
Different types of solar systems
There are several types of solar PV systems available at los-angeles.solar, which are suitable for different purposes. PV-direct units are those systems which work solely in the presence of sunlight. They are quite suitable for purposes like ventilation and pumping. Off-grid units are those solar systems which are usually found in remote areas and have an independent way of working.
They acquire their power from grids for performing electrical operations and a battery is needed for power storage. This helps the systems to work during cloudy weather or night-time. There are also some other gird-tied units which come with battery backup and hence, decreases the requirement for all-time energy provision.
Reasons for using solar electricity
- It’s environmental friendly in nature and has some beneficial as well as useful effects our economy, environment, and society. It reduces the cumulative and annual expenses and indirectly assists a lot in the protection of human health. Clean electricity is produced and very less pollution is created.
- It’s a kind of one time investment as you are required to pay the expenses for the system during the time of its installation. After this payment, energy is mainly obtained for free.
- You get independent choices in solar systems since they are not subjected to any kind of local utility terms and conditions, blackouts, rate increases an brownouts. Off-grids are especially cost-effective for rural areas.
Lastly, it can be seen that the nature of solar energy is highly democratic and it is a highly convenient energy option. As sunlight is available everywhere, there are very useful opportunities provided for the utilization of solar energy in electricity generation. Low maintenance is required for these systems and they have a very high reliability.
