Mostly, solar panel installation happens on rooftops, building tops, or wherever convenient places. Furthermore, solar panels need to install at a location where it gets exposure to sunlight directly.
Before the installation of solar panels, take care of any restrictions from the sunlight. Remove unwanted restrictions or items that may block sunlight to your solar system. Moreover, make sure no object may cast a shadow over solar photovoltaic panels and also trace the path of the sun.
Types of Solar Panel Mounts:
Solar Panel mounts help us in installing photovoltaic panels. These mounts are available in three main types:
- Pole mounts;
- Roof-ground mounts; and
- Flush mounts.
With the help of these mounts, we can install the solar panels wherever we need them.
Solar panels generate electricity for both commercials as well as for home use. In both cases, the photovoltaic panels are installed on the Rooftop to get the maximum amount of sunlight and generate electricity from the photovoltaic power system.
Steps to be followed while installing solar panels:
Step 1: Mount Installation
The first step is to fix the mounts that support the solar panels. Depending upon the requirement, it can be Roof-Top or Flush mounts. This foundation on the base provides support and stability. Moreover, while installing PV panels ( monocrystalline or polycrystalline), care is taken in a direction. For countries in the northern hemisphere, the best place to install solar panels is the south. Whereas in the southern hemisphere, the best place in the north.
Additionally, the mounting structure must be slightly tilted. The angle of the tilt could be between 18 to 36 degrees. We can use a solar tracker for conversion efficiency and, many companies do that.
Step -2: Install the solar panels
The next step is to fix the solar panels with a mounting structure by tightening them with nuts and bolts. Whatever we install, the entire system is securely connected so that it should be sturdy and lasts long.
Step 3: Electrical wiring
The next step is electrical wiring. During the wiring process, Universal connectors like MC4 to be used for all types of solar panels for connection. These panels to be electrically connected in the following series:
- Series connection: In this case, the positive (+) wire to be connected to one PV module and the negative (-) wire to be connected to another module. This series of wiring increases the voltage match and battery bank.
- Parallel Connection: In this case, positive (+) wire to positive (+) wire and negative (-) wire to negative (-) wire is connected. In this series, the voltage remains the same.
Step 4: Solar Inverter Connection
In this step, the system to be connected to the solar inverter. The positive wire from the solar panel connects to the positive terminal of the inverter. The negative wire from the solar panel connects to the negative terminal of the inverter.
Later on, the solar inverter to be connected to the solar battery and grid input to generate electricity.
Step 5: Connect the solar inverter and the solar battery
The next procedure is to connect the solar inverter to the solar battery. The positive terminal of the battery connects to the positive terminal of the inverter. The negative terminal of the battery connects to the negative terminal of the inverter. The battery is needed in the off-grid solar system to store the electricity back up.
Step 6: Connect the solar inverter to the grid
Now, connect the solar inverter to the grid. Make the connection with the help of a simple plug connected to the main power switchboard. An output wire connects to the electric board that supplies electricity to the home.
Step 7: Start Solar Inverter
After complete wiring and connections, then start the inverter. Most solar inverters will have a digital display to show the stats regarding the generation and usage of the solar unit.
