How does a 150 watt panel work?

A 150 watt solar panel works by setting electrons free from its cell when the sunlight strikes the solar panel. The electrons become free to move and under certain conditions of the panel, they start moving in the same direction. The flow of electrons in a particular direction generates current, particularly direct current. The direct current generated is converted to alternating current using a solar inverter as DC cannot run home appliances directly. You can use a battery to store the power for future use.

#1. 150 Watt Solar Panel Price

In India, the solar price per watt usually lies between Rs.24 to Rs.38 for every single watt. Hence, the rate highly depends on the capacity of the solar panel. Besides, brand, type, variant and your state play a major role in determining the overall price of the panels. Since 150 watt is among the lowest capacity for a solar panel, it is comparatively cheaper and affordable. 

150 watt solar panel price starts from @ Rs.4,500 with Vikram Solar to @ Rs.7,200 with Tata Solar online in India. Here is the list of top branded 150 watt solar panels with their prices.

#2. Types of 150 Watt Solar Panel

The type of solar panel largely affects the overall productivity of the solar system. You must be aware of the best type of solar panel that can suit your place and budget well. There are three types of 150 Watt solar panels in general. Each has its specific value. Keep reading to know which among the three can work best for you in most of the terms. 

The three types of 150 watt solar panels are:

Types of solar panel
Types of solar panel

Both mono-crystalline and poly-crystalline solar panels perform the same function in the composite solar system. They take energy from the sun and convert it into electricity. Both of them are made of silicon, which is used for solar panels as it is a highly durable element. Still, there are a lot of differences between the two.

Monocrystalline solar panels have solar cells made of single crystals of silicon while polycrystalline have multiple silicon solar cells melted together. Monocrystalline modules are 19% efficient but expensive while polycrystalline panels are 16% efficient but cost-effective. Now it is up to you which combination of features you prefer. Or you can go with the third with the most advanced features among all.

Bifacial solar panels are the latest type of solar panels present in the market. They are designed with certain technology that can produce electricity from both sides of its surface- front and rear. This feature makes them up to 22% efficient and much more beneficial than the other two in every aspect except for the price as they are quite expensive.

Let’s compare all of these 150 watt solar panels and see how they differ.
