This Touchscreen Solar Inverter is helping me Save Massively on Electricity While Giving 24×7 Power to My Factory

Mr. Harry Angapengawala owns a Prawn Cultivating center (Zingga Talav) in Surat district, Gujarat. This center is located in a remote area of Surat where no electricity supply is available. To run their day to day light load in their office and a 5-room servant quarter, Mr. Harry installed a 10 KW diesel generator. He paid heavily every month for running this generator.


Harry says, “I was frustrated with spending so much money daily for electricity. Not only was the generator expense, it created loud noise and polluted the environment. So I approached Mr. Mehul (Su-Kam’s authorized distributor) and asked for his advice in reducing his electricity bills.”

Mehul advised him to install a solar power conditioning unit, which has an inbuilt solar charge controller with a battery bank and solar panels.

Surat state receives ample amount of sunlight. With an average of 11 hours and 17 minutes of daylight in this month of April, a solar installation would be perfect for this area.


And so Mr. Harry installed the following in his office –

Technical Specifications:

  1. Su-Kam Brainy Touch – 2.5KVA/48V
  2. Battery 200AH – 4
  3. Su-Kam Solar Panels – 2KW


How is a solar system better than a diesel generator?

Let us understand the real cost difference between the diesel generator and a solar system. Mr. Harry ran a 10 KW generator for his load. First, we need to understand how much load runs on this 10 KW generator. Harry says he ran about 2 KW load on this generator.  So total load = 2000 W, which is 20% of the full load. See this table for more details –

Size of generator 1/4th Load 1/2th Load 3/4th Load Full load
10 KW 1 Liters/Hour 1.4 Liters/Hour 2.1 Liters/Hour 2.6 Liters/Hour


Now we need to calculate the number of hours that the generator runs typically in one day. So since there is no power available here during the day, it is safe to assume that the generator runs for 9 hours every day. Therefore since about 20% load is running, the generator will consume – 1 Liter * 9 = 9 Liters per day.

The cost of diesel in Surat is INR 57.4 per liter. So Harry would be paying INR 517 every day on diesel expenses. If we even assume that Harry is running his generator for 20 days a month, this would amount to INR 10,340 per month.

And around 1 lakh 25 thousand per year. Need I say more?


After the initial cost of investment for installing a solar system is recovered in few years, Harry will be saving about 1.2 lakh rupees per year after installing solar.

[Note: The reduction in electricity bill may vary from individual to individual (even when the technical specifications of the system are the same) depending on factors such as weather, electricity consumption pattern etc. Su-Kam cannot guarantee the amount of solar savings that one will make as a result of installing its solar power system.]

And this is just the analysis of the cost difference. How else can opting for a DG set instead of a solar battery backup system be harmful?

How much is CO2 emission reduced by this solar system?

Since Harry installed a 2.5 KW solar system and we are assuming that approximate units consumed per KW per day are 3.5 KWh, then CO2 emission reduced is 2.5 tons per year. This is in comparison to using a diesel generator instead.

To calculate carbon emission reduced by your solar plant approximately, keep in mind one thumb rule –

Reduction of CO2 emission per 1 KWh of solar power is approximate – 0.8 Kg of CO2.

Load running and units generated from this solar system

This system generates 10 units. And runs load that includes 10 tube lights and 10 fans in the servant quarters, and 0.8 ton AC, one laptop, one fan, and two tube lights.


After this Mehul reported to us, “We have installed Brainy Touch in this office as well as in the 5-room servant quarters to run their load comfortably on solar power. This area receives no electricity, so they used a 10 KW genset before this installation to run their load. Brainy Touch has an inbuilt MPPT solar charge controller that extracts maximum solar power from solar panels and helps to reduce electricity bills.”

We wish Mr. Harry all the best and best of luck for the coming days. We are glad to know that the citizens of India are taking such a keen interest in solar power.
