There’s no doubt about the fact that solar power is gradually replacing the usage of fossil fuels to generate electricity. And why not?

The electricity that comes from fossil fuels is polluting and super expensive. Both these issues can be easily overcome by installing solar panels. 

The panel that we will be elaborating on in this guide is a 150 watt solar panel: its types, uses, benefits, and much more. We will also walk you through the 150 watt solar panel price details.

Dive in for all the information.

How does a 150-Watt Solar Panel Works? 

Let’s begin the discussion with how a 150 watt solar panel works. These panels don’t work differently than the other solar panels. 

When the sun’s rays fall on the panel, the photons in those rays set free some electrons. When the free electrons move in a specific direction, they generate a direct current. 

That’s how electric current is produced. A solar inverter transforms direct current into alternating current.  

You can then use the AC power to charge up electronic devices. 

Pretty simple, isn’t it? Now let’s move on to the types of 150-watt solar panels you can opt for purchase. 

Types of 150-Watt Solar Panels 

Speaking of the types, there are three classifications of 150-watt solar panels: Polycrystalline, Monocrystalline, and Bifacial. Let’s understand the specifications of each. 

  • Monocrystalline: These solar panels are made of mono silicon cells and they provide 19% to 20% energy efficiency. It makes these solar panels more expensive than polycrystalline solar panels. Although the monocrystalline 150 watt solar panel price is higher than polycrystalline, its energy output is also higher. 
  • Polycrystalline: As discussed above, Polycrystalline solar panels are more cost-effective than monocrystalline. They offer a 16-17% efficiency and are made of multiple silicon cells. 
  • Bifacial: These are the most advanced solar panels on the market. A unique factor about these solar panels is that they are made in a manner that the panels can absorb the sun’s energy from both the front and rear sides. Hence, undoubtedly, their energy efficiency is the highest i.e., up to 22%. But this also makes them the most expensive among the other types. 

150 W Solar Panel Price

We have talked enough about cost-effective and expensive solar panels. But what exactly is the 150 watt solar panel price? 

Well, there is no definite price for solar panels. It depends on the brand and the type of panel you wish to purchase. 

We can still give you an idea about the range of 150 watt solar panel price in India.

  • – The monocrystalline 150 watt solar panel price ranges from Rs. 4050 to Rs. 4950.
  • – The polycrystalline 150 watt solar panel price ranges from Rs. 3442 to Rs. 4208. 

Bifacial solar panels are the most expensive and not that widely used in India. Depending on the factors we just stated, the price can differ. 

Specifications of a 150 watt Solar Panel 

Before purchasing 150-watt PV panels, you must know their specifications to make the right purchase. 

You must understand which cells are used in making these panels and the warranty period. 

As far as the composition is concerned, mono cells are used to make monocrystalline and bifacial solar panels. Polycrystalline solar panels are made up of multi-crystalline cells. 

  • – Whichever solar panel type you purchase, the manufacturing defect warranty for a 150W PV panel will be between 2 to 5 years.
  • – The output performance warranty for a 150 W solar panel is 5 to 10 years. 

Benefits of a 150 Watt Solar Panel 

Now, let’s learn the benefits of buying a 150-watt PV panel. 

  • – Even in case of low irradiance, these panels work. The efficiency slightly drops, but power is still generated.
  • – They have a robust structure.  
  • – The 150-watt solar panels have a good power tolerance. 
  • – The 150 watt solar panel price is more economical than solar panels of higher wattages. 

These are the top benefits of using 150 W solar panels; but are there any drawbacks too? Let us find out!

Cons of 150 W Solar Panels 

There aren’t many cons to using 150-watt solar panels, except that one single 150 watt panel cannot charge big appliances single-handedly. 

They are ideal for devices like small solar inverters, solar home lighting, navigation lights, and water pumping. 

If you want to charge bigger appliances, you must purchase several 150 W solar panels to increase energy efficiency.  

So, how many solar panels of 150 watts should you ideally install? We’ll be discussing this in the next segment.  

How Many 150 W Solar Panels Do You Need? 

The answer to this question depends on how much energy you want to consume from the solar panel for powering your electric appliances. 

Besides, the type of panels and the brand also play a significant role in selecting the number of panels that need to be installed. 

Generally, if you want solar panels for a 1KW solar system, you will need six or seven solar panels. How? 

Well, by making an easy calculation. All you need to do is divide the solar system’s capacity by the solar panel’s capacity.

For example: 1000 watts (1KW)/150 watts = 6.66. 

So, 7 150-watt solar panels are required for a 1 KW solar system.

To simplify your decision-making, here’s a detailed reference: 

  • – For a 2KW solar system, 13 panels would be needed (2000 watts/150 watts = 13.33).
  • – For a 3KW solar system, 20 panels would be needed (3000 watts/150 watts = 20).
  • – For a 4KW solar system, 27 panels would be needed (4000 watts/150 watts = 26.66). 
  • – For a 5KW solar system, 33 panels would be needed (5000 watts/150 watts = 33.33). 

Applications of a 150-Watt Solar Panel 

Let’s now discuss where you can use 150-watt PV panels. A 150-watt panel can be used in: 

  • – Solar Home Lighting System
  • – Solar Water Pump
  • – Solar inverter 
  • – Navigation lights

Since the 150 watt solar panel price is affordable, these panels are worthwhile options to carry out all the applications listed above.

Subsidy on a 150-Watt Solar Panel 

Usually, a subsidy is offered for solar panels that have a wattage power of at least 330.

However, there could still be exceptions. 

That being said, the subsidy that the government offers for homeowners and housing societies in general is:

  • – 40% of L1 rates for 1 to 3 KW solar systems.
  • – 20% of L1 rates for solar systems above 3 KW and up to 10 KW. For housing societies, the 20% subsidy on L1 prices is offered up to 500 KW installations.


A 150-watt solar panel is a good choice if you want an affordable solar solution for your electricity needs. Consider the factors specified above to make the right selection. 

Also, ask the manufacturer about the ideal 150 watt solar panel price and other details before making an investment. You can also ask your solar vendor about the 150 watt solar panel price.


Q. What can I run on 150-watt solar panels?

You can run mobile phones, tablets, laptops, and many other small electronic appliances with 150 W solar panels. 

Since the 150 watt solar panel price is quite affordable, these panels are quite useful.

Q. Can 150-watt solar panels work under low light?

Yes, they can work under low light conditions. The efficiency could be lower, but the panel still works.

Q. What can one 150-watt solar panel operate?

One 150-watt panel can operate lights and LED torches.
