How much will it cost to install 7 kilowatt solar panels?

How much will it cost to install 7 kilowatt solar panel, what will happen in 7kw solar panel, 7kw solar panel price with subsidy, 7kw solar system off grid

We mostly use 7kw solar panels in big offices, schools, journal stores etc. Because there we have to run more fans, more lights and apart from this we have to run bigger fridges or appliances like air-conditioners. But if you want to run an air conditioner or room heater in your house, then for that also you will need a solar system of about 6 to 7 kilowatts.

7 kw solar panel can generate about 30 units of electricity in a day, so if you consume electricity for 25 to 30 minutes in a day then only 7 kw solar system will be perfect for you. But you can prepare a 7 kilowatt solar system using a separate inverter.

How much will it cost to install 7 kilowatt solar panels?

You can see three types of solar panels in the market which we can use at home, office, shop, petrol pump etc. The price of these three solar panels is different because their technology is different and their working capacity is also different.

Which are better than polycrystalline solar panels, that is why their price is also slightly higher. Last of all comes Bifacial solar panel, which is the latest technology and the most expensive solar panel.

Types of Solar Panels

  • 7kw Poly Crystalline Solar Panel Price – Rs.2,10,000
  • 7kw Mono PERC half cut Solar Panel Price – Rs.245,000
  • 7kw Bifacial Solar Panel Price – Rs.2,80,000

Solar panels of all three technologies are in their right place. Those who have a low budget and want to install 7 kilowatt solar panels at low cost can buy polycrystalline technology solar panels. Anyone who wants to get solar panels of good technology can install solar panels of Mono Perc Half Cut technology. If you have a good budget and want to buy solar panels with the most advanced and latest technology, then you can buy bifacial solar panels.

Solar Charge Controller For 7kw Solar Panel

If you want to install 7 kilo watt solar panels on your old inverter battery, you will need a solar charge controller. With the help of which you will be able to install 7 kilo watt solar panels on your inverter. But for this you must have an inverter with at least 10 batteries, only then you can install 7 kilowatt panels.

1. Smarten Pwm-120v 50a Savior Solar Charge Controller

With the help of this solar charge controller, you can install up to 8 kilowatt solar panels on an inverter with 10 batteries. The VOC of this solar charge controller is approximately 265v.

Other Expenses

Apart from the solar panel and solar charge controller, there are expenses involved in installing a solar system such as stand for the solar panel, wires to connect the solar panel to the solar charge controller and safety devices such as ACDB, DCDB. So their expenses will be around ₹40000.

Total cost of installing 7 kilowatt solar panel

So above you have been told about solar panels of different technologies, on the same basis their cost will be different, so here the cost of solar charge controller and stand & wire will be the same and the cost of solar panel will be different.

  • If you prepare a 7 kilowatt system by using polycrystalline solar panels, your expenses will be around Rs.2,65,000 lakh.
  • Mono Perc: If you prepare a 7 kilowatt system with solar panels, your expenses will be around Rs.3,00,000.
  • If you prepare a 7 kilowatt system by using solar panels, it will cost you approximately Rs.3,35,000.

Cost of installing 7kw solar system

Now let’s talk about what will be the total cost if you want to install a new 7 kilowatt solar system. For which you will have to buy a new solar inverter, battery and solar panels. If you want to generate 30 units of electricity in just one day, then you can buy a 7.5kva solar inverter.

But if you want to run even a 7kw load, then for this you will have to buy a transformerless 6kva solar inverter. Because inverters are of the latest technology. On which you can run a load of 7 kW and also install panels of 7 kW.

Cost of installing Microtek 7 kilowatt solar system

Luminous Solarverter PRO PCU – 7.5KVA

Luminous Solarverter PRO PCU – 7.5KVA Solar Inverter MPPT type solar inverter which can run load up to 7500Va. The Voc range of this inverter is 480V Vdc, so you can also use 36/60/72 cell solar panels on this inverter.

In this you get a solar charge controller of 50A current rating. You can install solar panels up to 7500w on this inverter. So someone who has a load of up to 7kw can use this inverter. By installing 7500w panels on this inverter, you can prepare a good 7500w solar system.
