The boom of the solar industry has created a lot of queries among the audience. To resolve some of them, we have come up with an article that will provide you an insight into solar energy, how they operate, the benefits and the solar installation procedure.
What is Solar Energy?
Solar energy was discovered by Alexandre Edmond Becquerel in 1839 and called it “the photovoltaic effect”.It is defined as the energy generated from converting sunlight to electricity with the help of photovoltaic panels.
How Does it Work?
Solar panels are a group of PV cells connected together, which are made from a specially treated silicon that has positive and negative sides to transmit electricity. These cells help store the photons received from sunlight and convert them into DC current which cannot be used to power household or industrial appliances. Hence, an inverter is used to convert this energy to AC current. If excess energy is generated, it will be sent to the grid with the help of a net meter or stored in a battery backup depending on your Solar PV system.
Benefits of Installing Solar
- Save money on bills with lower to zero utility tariff rates.
- Avoid increasing utility tariff rates
- Reduces your carbon footprint.
- Businesses and industries can boost their PR campaign by promoting solar installation projects.
- Appreciates the value of your home/ business.
- Returns your investment cost within a couple of years.
Procedure for Installing Your Solar PV Systems
Before installing, our technician conducts a survey of the area to understand multiple factors such as,
- The area is available to set up solar panels.100 sq.ftsurface area can setup panels that generate 1Kw of power.
- If the area is shadow free.
- What direction the panels need to face for maximum solar generation.
- For rooftop solar installation, the age of the infrastructure is important to know if it can hold the weight of the solar panels.
- The area is available for an inverter.
- If there is access to the roof for maintenance and setup work.
- How much cable is required to connect all the components?
Once the survey is completed and the engineer understands his requirements, they procure the components to assemble the solar PV system. Solar panels, DC distribution box, inverter, AC distribution box, cables, lightning arrester and a net meter (on-grid) or battery backup (off-grid) are the core components required for set up.
Once the components are procured, a foundation is set depending on the base. There are three types of bases RCC roof or metal sheet for rooftop solar and leveled surface for ground-mounted solar installations.
Once the foundation is set, we move to install the solar PV systems.
- Erecting poles, rafters, and purlin to support the solar panels.
- Install solar panels.
- Using a string connection to connect all the panels together.
- Connecting the panels to a DC distribution box.
- Connecting the DC distribution box to an inverter.
- Connecting the inverter to an AC distribution box.
- Earthing the system
We hope this article has provided you clarification on the benefits and steps involved in installing solar. The next step is to maintain these panels well for a maximum generation. Visit our other blogs for more details.
