My 100% Solar Home Has 10 Fans and Lights, 1.5 Ton AC, Fridge and TV. Know the Tech Specs of My Solar System:

Mr. Mandeep Khamboja, lives in Village Titu Khera District Sirsa, Haryana. The area that this home is does not receive any power supply during the day time. They were running their home appliances only after sun set when electricity is available for few hours. Mandeep and his family were struggling with the electricity condition and wanted a permanent solution for this.

Then Mandeep’s family friends explained the benefits of solar power to him and his wife. So he decided he must opt for solar power for his petrol pump.


He then approached Su-Kam’s authorized distributor Mr. Lalit located in Haryana.

Sirsa district approximately receives 12 hours 30 mins of daylight every day in this month of May, installing a solar system in this area was a perfect solution.


Mr. Lalit has been dealing with solar system installations for a while now and after careful inspection of the home, he and his team of qualified engineers gave the following suggestions –

Technical Specifications:

  1. Su-Kam’s Solar PCU – 6.25KVA/96V
  2. Su-Kam’s Solar panels – 250W * 16 panels (4KW)
  3. Su-kam’s batteries – 8 (150AH)


How Is A Solar System Better Than A Diesel Generator?

Let us understand the real cost difference between diesel generator and a solar system.

Let us assume Mandeep would have gone for an 8KW diesel generator. First, we need to understand how much load will run on this 8KW generator. Mandeep is running approximately 4KW load.


So total load = 4000 Watts

We can safely say it is approximately 50% of the full load.

A typical diesel generator running at 1/2th Load will consume 1.2Liters of Diesel per hour on an average. See this table for more details –

Size of generator 1/4th Load 1/2th Load 3/4th Load Full Load
8KW 0.9 Liters/Hour 1.2 Liters/Hour 1.7 Liters/Hour 2.1 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 7 Hours every day.

Therefore 1.2 Liters * 7 = 8.4 Liters per day.

The cost of diesel in Haryana is Rs. 56.85. So Mandeep would be paying Rs. 477 every day on diesel expenses. If we even assume that they are using the generator for 25 days a month this would amount to INR 12000 per month.

Need I say more? Other than the initial cost of investment for installing a solar system that will be recovered in few years, Mandeep will be saving about 1 lakh 43 thousand rupees per year after installing solar.

Note: The reduction in electricity bill and diesel generator use (wherever applicable) 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 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?


Harmful Exhaust from Diesel Generators and Its Adverse Effects

In the past couple of months, air pollution in India is at an all-time high. The worst factor in air pollution is soot, generated from diesel generators/vehicles.

NOx (NOx is a generic term for the mono-nitrogen oxides NO and NO2 (nitric oxide and nitrogen dioxide). They are produced from the reaction of nitrogen, oxygen. It reacts with moisture in the air to form nitric acid which is inhaled deep into the lungs.

The toxic soot is the number one cause of increasing risk of cancer worldwide. Estimating figures, it is known that a standby diesel generator produces around 11 to 13Kgs of Nitrogen Oxides per Mega Hour of power generated. And this is just one generator we are talking about as compared to zero pollution generated from a solar system.

Units Generated And Load Running From Solar Plant

The 4KW solar panel generates approximately 18 to 20 units per day depending on the weather conditions. The system runs the entire load of the home that essentially includes 1.5 ton AC, 750 litre fridge, 20 lights, 10 fans, mixer grinder and other electric plugs around the house. Mr. Mandeep is satisfied seeing his home turn into a solar powered station.

After the installation, we spoke to Lalit and he says, ‘We have installed a 6.25 KVA solar PCU that is designed to run the full load of their house. Mr. Mandeep. There is no electricity supply in day time. In summer season temperature rises up to 48 degree Celsius and in such a hot weather living without electricity is very difficult. So they decided to use solar energy for day time and contacted us. Then, we visited the site, measured the load and decided to install the system. Everything is working smoothly on solar power.’

It is a pleasure to see people really believing in solar power. We are glad to see another happy solar customer in India. Going solar has never been easier.
