31st January 2022  

Have you ever thought about installing solar panels somewhere? Although it seems like an idea that may be difficult initially, this task is simpler than you think. So, if you are building or renovating and are thinking about including a photovoltaic solar energy structure in your project, know 10 essential steps related to the solar panel installation process.

10 steps you need to know for proper installation -

  1. Analyze your electricity bill
  2. The very first step is to analyze your electricity bill before starting the solar panel installation process. By looking at your electricity bill, you will get an idea about your monthly consumption in kWh. Based on this number, you will calculate the "size" of your solar energy system as you will require a solar panel according to your demand for energy consumption. To accurately calculate this value, it is advisable to check the average monthly energy consumption, the average of the last 12 months.

  3. Choice of panel model and installation company
  4. Choosing the company that will supply and install solar energy equipment makes all the difference in the final result. There are several options for models and values of solar panels, which vary according to the consumer's objective, the planned investment, and the manufacturer. Start by simulating the cost required and the savings that can be generated. Choose a brand that exists in the market and offers the best solution for your project, allowing you to customize the structure for different environments.

  5. Technical and feasibility study
  6. Before installing the photovoltaic system, a study must be carried out to assess the structure of the building and the ideal type of equipment, according to the consumption profile. The electrical appliances in use and the number of people who will use the generated energy are considered. Another point evaluated is the characteristic of the solar radiation received at the installation site, which varies according to geographic region. From the study results, technical experts can define the ideal equipment for the owner's objective and budget for the acquisition.

  7. Calculate your budget
  8. Based on your monthly energy consumption shown on your electricity bill, you will be able to simulate the cost of installing solar energy in your home or business. According to your energy consumption, calculating the average cost needed for the solar panel installation process is possible. You need to consider the warranty, maintenance cost, and the number of panels required for the installation process.

  9. Access to the electricity grid
  10. Once the quantity and weight of the necessary panels and the installation area have been defined, it is essential to evaluate the conditions of integrating the photovoltaic solar system with the electrical network available in the property. For the energy generated by the capture of sunlight to reach the electrical equipment, the current generated must be conducted to the photovoltaic inverter and converted to the consumption pattern, following the system known as on-grid or off-grid.

  11. Facility Design, Permits, and Grant
  12. Once the previous step has been carried out, the installer will make an installation proposal with its respective production objectives and install solar panels on your roof. If you accept the proposal, it would be time to request the permits to legalize the self-consumption installation before mounting the solar panels and find out if there is any subsidy for installing solar panels in your community.

  13. Authorization of the energy concessionaire
  14. For the system to be finally implemented, the energy concessionaire operating in the region must authorize the installation in the property and its connection to the electricity grid. The professionals appointed for this task are specialized engineers and technicians, who use the technical study and the characteristics of the building to request approval from the electrical distribution company.

  15. Site inspection
  16. It is a very important step in the installation of solar panels. First, we need to inspect or search a site that can be used for installing solar panels. It should be in proper orientation with the sun. Also, the site should be at a good height or must have plain terrain.

  17. Installation of panels and converter
  18. Once authorized by the concessionaire, the installation of solar panels can be carried out by the selected company, based on the indicated project and the evaluation of the solar incidence on the property. The brackets for fixing the panels are attached to the location chosen, and the cables connecting the converter and the distribution board are connected. It is essential that all the material used is modern and of quality, with proper approval and certification.

  19. Dealership inspection
  20. The last step before starting to use photovoltaic solar energy is the inspection of the concessionaire. Technicians from the electric company go to the installation site and make sure that the entire implementation was carried out correctly, authorizing the start of use of the system. During the process, the meter is exchanged or installed for a bidirectional model, which measures how much energy will be injected into the network and consumed per day in the property, allowing energy credits to be made available with the utility.

After the 10 steps are completed, Solar Panel Installation becomes much easier. Solar electricity is currently appropriate not just for business buildings but also for residential ones. Although the cost of installing a solar power unit has progressively decreased, you may always go the DIY route to keep costs low.

By following this basic guide to putting up solar electricity, you may save money by installing a solar photovoltaic (PV) system yourself with the 10 steps provided. In this Solar Panel Installation Guide, we'll discuss how to install a solar panel step by step in detail.

Step-by-Step Instructions for Installing Solar Panels

Solar panels can provide power for both business and residential use. In both cases, photovoltaic panels are mounted on the roof to capture as much sunlight as possible and create as much power.

The following are the steps in the solar system installation procedure:

  • Installing the mount
  • The solar panel mounting brackets must be installed first. Roof-ground mounts or flush mounts may be used based on the application. This foundation gives stability and support. The orientation in which the PV panels (monocrystalline or polycrystalline) are mounted is carefully considered.

    The optimum direction to face solar panels in the Northern Hemisphere is south because it receives the most amount of sunlight. Both east and west directions are acceptable. The ideal direction for countries in the Southern Hemisphere is north.

    The mounting framework must again be adjusted slightly. The tilt angle might be anything from 18 to 36 degrees. Many firms utilize a solar tracker to increase conversion efficiency.

  • Put the solar panels in place
  • After that, the solar panels must be secured to the mounting structure using nuts and bolts. The entire construction is secured adequately to ensure that it is durable and long-lasting.

  • Install the electrical wiring
  • Electrical wiring comes next. During cabling, universal connectors such as MC4 are used since they may be used with any type of solar panel. The following sequence of electrical connections can be made between these panels:

    1. Series Connection: The positive (+) wire of one PV module is linked to another module's negative (–) wire in a series connection. The voltage match with the battery bank is improved with this type of wiring.

    2. Parallel Connection: In this scenario, the connections are positive (+) to positive (+) and negative (–) to negative (–). Each panel's wiring voltage remains the same with this style of wiring.

  • Connect the solar inverter to the system
  • The system must then be connected to a solar inverter. The positive wire from the solar panel is linked to the inverter's positive terminal, while the negative wire is connected to the inverter's negative terminal.

    To generate power, the solar inverter is linked to the Solar Battery and Grid Input.

  • Connect the solar inverter to the solar battery
  • After that, you must connect the solar inverter and solar battery. The battery's positive terminal is linked to the positive terminal of the inverter, and the negative terminal is connected to the negative terminal of the inverter. To store an electrical backup in an off-grid solar system, a battery is required.

  • Link the solar inverter to the power grid
  • The inverter must then be connected to the grid. A standard plug can be used to connect to the main power switchboard. The electric board that delivers electricity is linked to an output wire.

  • Turn on the solar inverter
  • When all of the electrical cabling and connections are complete, turn on the inverter switch on the home's main switch. Most solar inverters will include a digital display that will show you statistics about your solar unit's generation and use.

    And there you go. Your own solar system installation is complete! For years and years, you can enjoy FREE Renewable Green Energy!
