Clean energy is gaining ground rapidly just when greenhouse gases and carbon emissions are immensely hurting our ecosystem. Worldwide, two-thirds of solar power capacity has been installed since 2011. Fortunately, India has kept pace with the rapid development of clean solar power. Reports indicate that solar power generation in India increased by a whopping 86% in 2017.

It is now ideal to use solar power not only in commercial units but also for residential ones. The costs of installing a solar power unit have steadily dropped, but you can always try the DIY option to keep it within your budget. However, if your budget cannot afford it and you need to go for a loan, then calculate your mortgage with the help of a Mortgage Calculator.

You can save money by setting up a solar with solar photo-voltaic (PV) system yourself by reading this simple guide to set up solar power. Here is an in-depth look at how you can build and install a solar power unit for your home:

Step-by-step guide to set up solar power unit

Step 1: Gather solar power components

It all begins with gathering the basic ingredients of a solar power unit. You will need four major items – solar panels, charge controller, inverter, and a battery pack. In addition to these items, you will require a breaker, meter, MC4 connector, and fuses among other things. Keep in mind that it is essential to read the solar panel module instructions.

Before setting up a solar panel, it is crucial to choose a solar panel set that will be sufficient to run the appliances you want to operate. This is where the use of a solar panel calculator is seen. This smart tool will instantly let you know the number of solar panel plates you need to install so that the appliances could be run without any trouble

Step 2: Calculate your power load

Before getting to the solar installation task, it is crucial to sum up the power that you use at your home. This isn’t rocket science. All you have to do is to note down the home appliances that you use on a daily basis, which include television, lights, fan, and so on. Next, add the time for which these appliances run in a day. Go through the specification chart in your household electric appliances to check their usage duration or run time, and their power rating.

Now calculate the ‘Watt-Hour’ by multiplying the runtime of an appliance with its power rating. Follow this step for each electrical device, then sum up the individual watt-hour numbers to get the grand total. You can also simplify this calculation by using an online off-grid load calculator.

Step 3: Select and charge the battery

A major hiccup with solar power is that it doesn’t provide electricity when the sun goes down. However, you can easily crack this problem by using a battery. A lead-acid or a lithium-ion battery stores solar power generated during the daytime and discharges it at night. This provides a steady supply of energy, provided you have selected the optimum battery storage capacity. You will need a power controller to monitor your battery’s charging. These come between the panels and the battery. Such controllers are typically fitted with a small LED light that announces the charging state of the battery, and it adjusts the power that flows into the battery.

Step 4: Set up the inverter

Solar arrays produce electricity in direct current (DC), but electrical appliances use power in the form of alternating current (AC). Inverter is a device that saves the day by allowing you to use electrical devices without using adaptors. Inverters come in varying power wattages and types including square wave, modified sine-wave, and pure sine-wave inverters. Square waves are not compatible for all devices, while the output of modified sine wave is not suitable for certain appliances such as a fridge. This makes a pure sine wave inverter the best choice for your solar system.

Step 5: Fix the solar panels on your roof

Once the battery, controller, and inverters are ready, you need to get started with mounting the solar panels. Select the best spot for the panels on the roof or on open ground that receives an unhindered supply of the sun’s radiation. You can either make a mounting stand yourself or get it from the market. The tilt of the mounting stand should almost be equal to the latitude angle of your location. The proper setting of the solar panels is critical for their operation & maintenance. Hence, it is essential to ensure that the panels face the sun throughout the day.

In the last phase of this step, wire the solar panels. You can trace a small junction box at the back of the solar panel. The junction box has negative and positive signs of polarity. In a large sized-panel, the junction box has terminal wires too with an MC4 connector. However, you will have to align the junction box with external wires yourself if you use small solar panels. Use the black and red wire for negative and positive terminal connections, respectively.

Step 6: Connect the solar panels with battery

You need to connect the solar panels with a battery. In certain PV systems, these come paired together, so you don’t have to put in any additional effort. In cases that are not given as a single unit, you need to make series and parallel connections. You can make a series connection by connecting a device’s positive terminal with another device’s negative terminal. For a parallel connection, you need to connect one device’s negative terminal with another device’s negative terminal and so on. It is better to choose a durable lithium-ion battery as compared to a lead-acid battery, which is prone to breakdowns.

Step 7: Setup stands for inverter and battery

Your residential solar unit is incomplete without stands for the battery and inverter. Again, you have the option of building the metal stands or getting them. Once the allocated positions for the inverter and battery are ready, you can start working on the wiring. Start with wiring the controller. The first connection from the left is for connecting the controller with the solar panels. The second connection is for pairing the battery with the controller. The last connection is for connecting the controller to the direct DC load connection.

For connecting the solar panel with the charge controller, you will need a separate connector called an MC4 connector. Once the controller is connected to the battery, its LED lights should light up. Similarly, you will have to connect the inverter terminal to the battery’s terminal.

Following these steps can guide you to set up a solar power unit at your home. The high costs incurred in installing one can be reaped later on as solar energy is not only clean but also a cost-effective investment. If you want to do it yourself by putting together upcycled solar PV panels or a portable unit for camps, check out this guide on DIY solar panels.

  13. Is it possible to have a solar panel power system which operates in the day time only when it is possible to generate sufficient energy for home activities; but when the power generated is insufficient, the solar system detaches & the grid is attached? Thus every sunny day the solar system would run the home’s needs, but when near sunset, the system produced too little energy, a controller would sense this, disconnect the solar system, & engage the grid to the home. Likewise, if a day was too cloudy, the solar system would stay detached & the grid attached. What is such a controller called? Who sells it at what price?
