Like every other solar system, an off-grid solar system uses a solar panel to absorb sunlight and convert it into electricity. In the day time solar will run the connected load and balance energy will be stored in the solar battery. So in the daytime, the solar system runs home appliances generating electricity using sunlight and stores the extra energy into the battery bank. And at night when there is no sunlight, the appliances draw energy from the battery to keep running. Hence, the system works day and night. 

Before you dive into the solar world, you must collect every single piece of information about the type of solar system to be installed. In this article, you will get answers to all your questions related to an off-grid solar system.

Off-Grid Solar System: Components and Working

To estimate off-grid solar system prices, you must be aware of the components the system requires to work with. You can understand the importance of each of the components only after reading about its function. The list of these components is mentioned below.

Now the question arises- how do these components work to provide constant power? The working of these components is explained clearly through the below-mentioned steps.

  • The solar panels are the faces of the system that capture the sun’s energy. These devices convert the energy to DC power.
  • Then comes the use of a solar charge controller. The solar panels are wired with a solar charge controller to regulate the voltage of DC generated by the solar panel. The solar inverter cum controller will monitor and measure how much energy is being produced by the solar panel array; it has the ability to harvest the maximum possible energy.
  • This regulated DC gets stored in the battery bank wired with the solar charge controller. In the event of surplus availability of solar power and less load, it provides the possibility to store the energy in the battery and also cater the load simultaneously. The battery bank will allow excess solar energy to be stored and used later on when required.
  • Now, this stored power can be used any time using a solar inverter to convert DC into AC to power your home appliances.

Steps to Install an Off-Grid System

Once you decide to install an off-grid solar system the next step is installation. Though the steps are complex which calls for the need for professionals to install the solar system, focusing on individual steps can make it much easier. Install the system to reduce off-grid solar system prices using the guidelines mentioned below.

#1. Calculate your home load

Before making any investment, calculate your energy needs. You must know each type of load including-

  • Basic load (LED lights/Charging points/fan/etc.)
  • Large appliances (Refrigerator/Electric furnace)
  • Special loads (Solar Water Heater/Solar AC)

Calculating the load is not complex at all. Simply follow these steps-

    • Prepare a list of all the appliances you want to run using the solar system.
    • Estimate the time for which each of the appliances will run. 
    • Find out the power rating of each appliance from the specification chart.
    • Using the formula – Watt Hour = Run Time × Product Power Rating,

You can find the Watt Hour of every individual gadget.

#2. Select the components and brand

The selection of components and brands should be done carefully keeping in mind that the investment is one-time. To help you select appropriate components, we have listed the top manufacturers of each component.

#3. Ascend the Solar Panel

An off-grid solar system works best when installed on no sunlight obstructed areas like a ground or rooftop. No sunlight should be hindered and the solar panels should be tilted in the right direction. To mount the solar panels, follow these steps-

  • Screw the solar panel to the stand using holes located on the sides.
  • Find the junction box placed on the backside of the panel. The junction box has two signs (positive and negative) of polarity.
  • You have to use the red wire for positive and black for the negative terminal connection.

 

#4. Connect the Components

Since the system capacity you need for your home is not readily accessible, you’ll need to put in a small panel or batteries to fit the requirement. For the same purpose, you’ll need to connect the components in parallel and series connections. 

#5. Wire the components

For wiring purposes, you’ll need to keep out your toolbox consisting of copper wire, meter, fuses, breaker and MC4 connector. And then-

  • Attach the charge controller to the battery connecting the negative wires of both the devices and then connecting the positive ones.
  • Now use the wires to connect the controller to the solar panel. Also, you’ll need an MC4 connector here.

#6. The system is installed!

#8. Subsidy on Off-Grid System

The government is providing a huge subsidy on solar in order to promote solar power and bring India forward in the field of solar. You can also take advantage of this subsidy programme by installing an off-grid solar system. The subsidy rates are:

These subsidy rates may vary as per your state solar policy. Contact your state nodal agency for more info.

Yes, a 30% government subsidy on panel is available in specific areas. You need to check your state solar policy for more detail.

Off-grid solar inverters are available in two technologies.

  • MPPT solar inverter 
  • PWM solar inverter 

Solar inverters in off grid systems work as conventional inverters. It is just an upgrade for solar applications.

MPPT solar inverter can produce up to 96% power while PWM solar inverters can produce only 70% of total power. So comparatively MPPT inverter is better than PWM inverter.

Solar regulator is also known as a charge controller. It is a small electronic device which controls the voltage of power, passing into the existing or non-solar battery.

In India, the optimum angle is 20-30 degrees. But it may vary according to the position of the sun from state to state.

Yes, you should buy a complete system of a single brand. Reasons: (1) You will never face issues regarding after sale service. A single company will provide you with a solar panel, inverter and battery related solution. (2) If you buy solar components from various brands then you will have to pay more GST as it is 28% on solar battery, 18% on inverter and 5% on solar panel but on complete solar system it is only 5%.
