The sun is a magnificent and renewable resource that has the ability to sustain life on Earth by providing clean, renewable energy to all of its people. Solar photovoltaic (PV) cells turn the sun’s energy into electricity (photo = light, voltaic = electricity).
Daytime, the sun’s energy absorbs solar cells in your solar panels. This energy is collected by the cell’s circuit and converted to direct current (DC) energy. Direct current travels via an inverter, which transforms it to alternating current (AC), which is available from a wall outlet. This means you may use it at home, store it in a solar battery, or transmit it back to the grid.
How it works?
Photons are absorbed by solar panels, which create an electric current.
The energy generated by photons hitting the surface of the solar panel releases electrons from the atomic orbitals. The whole process is called the photoelectric effect. The average home has enough roof area for the number of solar panels needed to generate enough solar power to meet all electrical needs.
In a balanced grid connection, solar panels generate electricity during the day, which is used indoors at night. The grid metering program allows solar generator owners to be paid if the system produces more power than is needed at home. Solar panels with inverters can be sized to meet the most stringent load requirements.
Cost of solar panel
These are a couple of primary factors that will decide precisely the amount it will cost[i] to introduce sunlight based boards on your home:
- Your home’s normal utility expenses and energy utilization
- The normal work expenses and requests in your space
- Your roof’s sun oriented potential, or the measure of sun it gets yearly
- Labor cost in your area
- Solar mounts
- Solar inverters
A 5 to 6 kW solar panel system might be installed at home to minimize energy charges on ordinary dimensions’ homes.
The cash you save on your power accounts can save more than your underlying cost in 5 to 15 years using sunlight-based panels. Many solar discounts and incentives are available both from governmental and local energy providers, which may accelerate your profit from the venture essentially.
How many solar panel you need?
An annual 3,600 kWh to 4,800 kWh – will come from a sun-oriented Board structure.
A 5 kWh system produces around 5 To 7 kWh per year.
Each year about 12,000 kWh to 15,000 kWh can be generated using a 10 KWh system.
A 6kW solar-powered board framework for a 1,500 sq. ft. home costs a public average of $18,500. The cost per watt for solar panels can range from $2 to $3, and it is heavily influenced by the home’s topography. The average size of private solar panels is 3kW to 8kW, with total installation costs ranging from $9,255 to $28,000. Calculate the cost of a conventional solar board structure based on its size.
Installation Process
The roof is the most typical place where solar panels are installed. The majority of rooftops generally have the required installation[ii] standards to provide maximum sunlight on the panels.
Nevertheless, the solar panels could also be installed on the ground if installation on the roof is not applicable or desired. You only have to ensure sure nothings obstruct access to the sun.
Installation of solar panel on a roof:
- Groundwork
First, to ensure security during the whole installation procedure while on the roof, you must set up the scaffolding.
- Panel Mounting
The installation system must be equipped for the solar panel. The base is held by solar a panel. To maximize solar light exposure, the entire mounting structure should be inclined and angled at 18 to 35 degrees.
- Installing the Solar Panels
The solar panel must be put on the assembly structure itself when the assemblies are established. Ensure all the bolts and nuts are tightened so that they remain solid.
- Wiring
Link to electrical cables is the next phase in the installation procedure. As they are suited for all solar panel types, fuse connections are typically used. Ensure that while the wired installation residential power supply is switched down.
- Inverter
The solar inverter must then be linked to the system. It is frequently placed near the main panel and may be installed indoors and outdoors. When stored in a colder area, inverters are more efficient.
It must be kept away from the sun afternoon if the inverter is outdoors. The garage or utility room is generally the ideal site when it is put indoors, as they are cold and ventilated most of the year.
- Connecting a Solar Inverter with a Solar Battery
The solar inverter must then be linked to the solar battery. The solar battery storage system can prevent you from worrying about the absence of useable power during cloud times and reduce the cost of the solar battery system when installing it.
- Plug the Inverter to the Power Supply
Connect the inverter to the fuse box to create electricity. The amount of electricity generated by solar panels should also be measured using a production meter. You may monitor the operation with a laptop or even other devices for your solar system. For example, you may assess how much electricity you produce at some times and select when your washing machine or other utilities should be used.
Turn on the energy and test the solar panel system, newly installed. The setup of the solar panel then takes place.
Return on investment o solar panel: Every user and solar system have different payback times. Some households are spending more on the system. Some people consume more or reside in a costlier area of power.
The first year will see 20 percent of ROI for a conventional photovoltaic system or PV system.
NET METERING
Net metering means when an electricity provider records and provides you a declaration of credit for the extra electricity your solar system produces. A single solar panel will not create sufficient electricity, let alone power the power business with any energy. But, more than enough power can be generated with a complete solar power system. If you do, you can reduce your power costs and enhance your ROI.
