India is a fast emerging economy, which includes more than 100 million people and needs a large amount of energy. Our country is fifth in the world for electricity generation and expenditure. 72% of the population of India lives in villages and now in such a situation, the use of solar power in the energy production and conservation sector is best.

Before starting Solar panel installation business, there is a lot of information to be done, such as the market’s solar products, industry, installation, better suggestions and solutions for homes and offices. After this, you will have to make good connections with product suppliers and sales consultants so that solar equipment can be easily available and together with complete information about the product. So let us talk about how solar panels are installed.
Step 1: First of all, I understand the system diagram in the beginning; this will help you to understand further steps. In this diagram, you will be able to clarify which connections were and how to apply. Here the 12-volt batteries have been added parallel and the batteries attached are also connected to each other’s parallel.
Step 2: The solar panel has been connected to the charge controller before connecting it to the battery. You will easily find a solar charge controller in the market. This charge controller senses the current born in the solar panel with sunlight so that it charges the battery according to both the time of day and night. When the battery is fully charged, it automatically stops charging automatically.
Now you have to do some calculations here, like
- How many solar panels
- How much voltage should a solar panel
- How many voltages and ampere and how many batteries should
- Batteries Bake-Up Time
- Batteries Charging Time
UPS ratings according to the load.
- Suppose we load 800 watts Is up to
- Load = 800 watt.
- Inverter = rating?
- Back up time for Batteries = 3 Hours
- Required No. of solar panel =?
- of Batteries =?
- The inverter should be 25% more than the total load,
- 800 * (25/100) = 200
- 800 + 200 = 1000 watts.
- This is the rating of the inverter.
- Now required Back-up time = 3 Hours
- Suppose you are using a battery of 100Ah, 12V, then
- 12V * 100Ah = 1200wh
- Then for one battery Back-up time = 1200wh / 800W = 1.5 Hours
- But we need 3 hours of back-up time,
- Therefore 3 / 1.5 = 2
Here we are using 12 volt inverter, and the battery voltage is also 12 volt, keep in mind that the voltage in the parallel connection remains the same and the current is separated and the voltage across the series circuit is different and the current remains the same. is. When two voltages of 12 volts are added in parallel, the input voltage for the inverter will also be 12 volt and our inverter is also 12 volt. If our batteries were 6 volts and the inverter was 12 volt, then we would add the batteries to the series, so that the output of the batteries would be 6 + 6 = 12 volt.
When we have now cleared all the calculations here, how many batteries, how many solar panels and how to have connections between them (series or parallel), then you can start installation of solar panels by connecting them according to the diagram. Put solar panels on the roof or mount as soon as possible so that it does not move with the strong wind. Keep the batteries in a clean place where dust and water cannot be made and the sunlight also comes easily. Connect all the batteries to the solar panels connecting the charging controller and connect the output of the batteries to the inverter and the output of the inverter to the AC mains (load).
