Solar Panel Installation Guide

Solar Panel Installation Guide

Installation of Solar Panels is generally on building tops, rooftops, or stand-alone facilities. It is essential to install your solar panel at a place with the most direct sun exposure.

Solar Panels perform better when placed in direct sunlight. When installing a Solar Power system, positioning photovoltaic panels directly under the noontime sun would maximize the efficiency of photovoltaic units.

Before starting the installation process, remove any obstructions to sunlight, such as branches that might cause sunlight blockage to the solar unit. Trace the sun's path in the sky and always make sure no object should cast a shadow over photovoltaic panels. The operating efficiency of the solar unit will suffer because of shadow.

Do these things Before Solar Panel Installation

Calculate Cost

Calculate the cost for the type and size of the required Solar System. Governments of worldwide offer subsidies for the installation of solar panels to encourage renewable energy generation. Subsidy for Solar Systems is different in different countries. E.g., the subsidy provided by Australia is different from the Subsidy in India or China.

Equipment Needed

Check what equipments are needed for a solar energy system and make a list for batteries, charge controller, Power inverter, and Solar Panels.

Get an idea of the size of the System

Determine the requirement of the size of the solar system. The wattage of electrical appliances used should be added and calculate how many hours per day the machines will be used.

After following the above steps, we can know the wattage requirement, and depending on that; we can decide the size of the solar battery needed and the wire size. Correct wire size helps in preventing overheating and ensures maximum power transfer to batteries.

Solar Panel Installation Guide

Step-1: Mount Installation

Fix the mounts to support the Solar Panels. Depending on the requirement, mounts can be roof-ground mounts or flush mounts. This base structure provides support and sturdiness.  Care is taken on the direction in which the Photo Voltic panels will be installed. For Australia in the Southern Hemisphere, the best direction is North.

Step-2: Install the Solar Panels

Fix the solar panels on the mounting structure by tightening nuts and bolts. Care should be taken to secure the whole system properly so that it is sturdy and lasts long.

Step-3: Electrical Wiring

The electrical wiring is the next step. Universal Connectors like MC4 is used during wiring because these connectors can be connected with all type of solar panels. These panels can be electrically connected in the following series:

1. Serial Connection: The Positive (+) wire of one PV module is connected to another module's negative () wire.

2. Parallel Connection: Positive (+) to Positive (+) and Negative () to Negative () connection is done.

Step-4: Connect the System to Solar Inverter

The positive wire of the solar panel is connected to the positive terminal of the inverter and the negative wire to the negative terminal of the inverter.

The solar inverter is then connected to the Solar Battery and Grid input to produce electricity.

Step-5: Connect Solar Inverter and Solar Batteries

Connect the solar inverter and the solar battery. The battery's positive terminal is associated with the positive terminal of the inverter and negative to negative. The battery is needed in off-grid solar systems to store electricity backup.

Step-6: Solar Inverter to Grid Connection

Connect the inverter to the grid. To make this connection, a regular plug is used to connect to the main power switchboard. An output wire is connected with an electric board that supplies electricity to the home.

Step: 7: Start Solar Inverter

Once all electrical wiring and connections are complete, it is time to start the inverter switch ON the Home's Main Switch. Most solar inverters will have digital displays to show you stats regarding the generation and usage of solar units.
