Complete Guide to 30kW Solar System: Cost, Savings & Setup

Complete Guide to 30kW Solar System: Cost, Savings & Setup : Heavy equipment is used in many homes, offices and commercial buildings, that is why most electricity is used there. Due to high electricity usage, the electricity bill is also very high. Apart from this, if there are frequent power cuts, then many important works get stopped. And there are always more power cuts during summers. So the only best and effective solution to both these problems is solar panels. By installing solar panels, you can reduce your electricity bill and also get good battery backup.

If you also want to reduce your electricity bill and want to run your heavy load during power cuts, then in this post you will be given complete information about 30Kw solar system. We can install 3 types of solar systems – On Grid, Off Grid & Hybrid.

If you just want to reduce your electricity bill and you have 24 hour electricity, then you can get an On Grid solar system installed, which you will get at a very low price because you will not have to install a battery in this solar system, so your battery cost is saved. But if you have to run your heavy equipment during power cuts, then you can get an Off Grid or Hybrid solar system installed.

Cost of installing 30Kw On Grid Solar System

To install an On Grid solar system, we need only two components – first a solar inverter and second a solar panel. In the market, you can find On Grid solar inverters from many companies, which come with 30Kw load capacity and 40Kw panel capacity. That means if you want to add 10 more kW solar panels to your 30 kW solar system in the future, you can do it on the inverter.

The grid tie string inverter used in the On Grid system is very small in size, so you can easily install it on the wall. You will get the feature of remote monitoring in this inverter, so that you can see the complete information of the inverter on your phone from anywhere.

How much electricity your solar system has generated, how much electricity you have imported or exported, you will get to see all this information on the mobile app. This solar inverter is of transformerless technology, hence its efficiency is 98.6%.

Inside this inverter, you get two MPPT trackers, so that you can install solar panels up to 40 kilowatts on this inverter. You are also given a display in this inverter, on which you will get complete information about the electricity produced from the solar system and along with that, buttons are also given for customization. If you want to set any parameter inside the inverter, then you can do it with the help of those buttons.

UTL 540W Solar Panels

For a 30 kW solar system, solar panels larger than 500W are suitable, that is why a 30 kW solar system can be made from 56 solar panels of 540W each. These solar panels will be available at the rate of 17 to 18 rupees per watt. If you buy solar panels of the latest HJT technology, then you will get them at the rate of 22 to 23 rupees per watt.

But you will get solar panels of HJT technology in 730W, so that you can create a 30Kw solar system in less space. But the cost of your solar panel will increase a lot. You will get 56 solar panels of 540W for about ₹5,14,000, but you will get 42 solar panels of 730W for about ₹6,74,000.

If you have space issues, you can buy solar panels with the latest HJT technology by spending an additional ₹1,60,000. But if you want to save money, you can use a 540W solar panel.

Safety Devices

ACDB, DCDB, Earthing Kit and Lightning Arrestor are used to keep the solar system safe. But apart from this, you will need a stand to install the solar panel inside the solar system and a wire will be needed to connect the solar panel with the inverter, which will cost around ₹ 2 lakh.

Cost of installing 30Kw Solar System

Above you have been told the cost of solar inverter, solar panel and the components used in the system, now you can add them and see what the total cost becomes:

• Solar Panels: ₹5,20,000
• Inverter: ₹1,20,000
• Extra Material Cost: ₹2,00,000
• Total: ₹8,40,000

The cost of installing this 30 kW solar system will be around ₹8,40,000. But this cost can also be more or less, depending on which company you are installing. If you install solar panels of the latest technology, then this cost will increase further. If you increase the height of the structure, then also its cost will increase. So in this way you can increase or decrease the cost of the solar system according to your need.

How much electricity will a 30 kW solar system generate

Will generate electricity worth 3 lakhs every year: A 30 kW solar system can generate about 150 units of electricity per day. It can generate 4500 units of electricity every month and if you talk about 1 year, then it can generate about 54000 units of electricity. If we consider ₹7 per unit , then it will be able to generate electricity worth about ₹3,78,000 every year. But the same amount of electricity cannot be generated every year, still it can easily generate electricity worth more than ₹3,00,000 every year.

30Kw Off Grid Solar System Price

Where there is a lot of problem of power cuts and more load has to be run, you can install a 30Kw Off Grid or Hybrid Solar System. But installing this solar system costs you a lot because for a 30kw solar system you have to use 30 lead acid batteries.

If you have to run the load only during the day, then you can use a smaller battery, but you will still have to install 30 batteries. Although you can find solar inverters with smaller batteries in the market, a 30 kW solar system is quite large and it gets damaged if you run a higher load on a smaller battery. That is why you should either install a setup with lithium batteries or a setup with 30 batteries.

UTL Zeta 30kVA Solar CPU

This is a hybrid solar inverter from UTL company, but you will get less load capacity in this solar inverter. You will be able to install solar panels up to 30 kW on it, but you will be able to run the load only up to 22-23 Kw. And you get this inverter for about ₹ 1,90,000.

You can create your own 30 kW solar system by installing 20 batteries on it, but this solar inverter will be best for those who need to run the load only during the day, because during the day most of your load will be run by the solar panel, so there will not be much load on the battery, due to which the life of the battery remains intact.

You will get 20 lead acid batteries for around ₹2,50,000. If your budget is low then you can buy a battery of low Ah which you will get for around ₹200000.

Total Cost

Above you have been told the price of the solar panel and its components, by just adding the price of hybrid inverter and battery to it you can find out how much a 30 kW hybrid solar system would cost:

• Solar Panels: ₹5,20,000
• Inverter: ₹1,90,000
• Battery: ₹2,50,000
• Extra Material Cost: ₹2,00,000
• Total: ₹11,60,000

So you can install a 30 kW hybrid solar system for around ₹ 11,60,000. But your power loss in this system will be very high because it has a Transformer Based Solar Inverter and Lead Acid battery.

If you charge a Lead Acid battery with 50 units, you will get only 30 units back. 20 units will be wasted only in charging and discharging the battery. That is why you should install 35 kW solar panels on top of a 30 kW hybrid system, only then you will get good electricity.

Because a 5 kW solar system produces about 20 to 25 units of electricity in a day, so whatever loss of electricity will occur in charging and discharging the battery, you will be able to cover that much loss with solar panels.

What loads can run on a 30 kW solar system

If you install an On Grid solar system, you can run as much load as you want on it, because in an On Grid solar system your load runs by combining the power of the solar panel and the grid. That is why even if you run a load of 40 kilowatts in an On Grid system, there will be no problem.

Talking about Off Grid or Hybrid, you can run the load on the inverter according to its capacity. Supposing you have bought a 30kVA solar inverter, then you can run a load of up to 22 or 23 kW on it. But If you want to run a full 30 kW load, then you will have to use a 50kVA solar inverter.

If you use a solar inverter with transformer less technology, then you can run a load of up to 30 kW on a 32 Kw hybrid inverter because the efficiency of a transformer less hybrid inverter is up to 98%. And if you use a lithium battery with it, then this solar system becomes quite efficient. The power loss of 20 units in a transformer based inverter is up to about 5 units in a transformer less inverter.

But the cost of installing transformer less technology inverter and lithium battery is quite high. If you do not have any budget issues, then only you can install a 30 kW latest technology hybrid system, the total cost of which will be around ₹ 17 lakh.
