A solar panel is a collection of interconnected silicon solar cells that form a circuit. They are also known as photovoltaic solar modules, solar plates, solar PV modules, and solar power panels, etc.
Solar panels absorb sunlight and generate an electric current, which travels to your home apppliances via DC wires. On the front of the panel, there is a glass layer, followed by an insulating layer and a protective back sheet. A single solar panel can generate a certain amount of electricity. Therefore, most installations include multiple solar panels.

#1. How Solar Panel Works?
You’ve probably seen solar panels on rooftops in your neighbourhood, but do you know how they work? Let’s understand it in simple language. Solar panels are made of silicon solar cells. When sunlight hits a solar panel, electrons in the solar cell begin to move which initiates a flow of electricity. This is direct current, also known as DC electricity.
Unfortunately, most of our household appliances cannot be powered by direct current electricity. To convert solar power into usable electricity, it must first pass through a solar inverter. This inverter converts direct current (DC) electricity into alternating current (AC) electricity, which is compatible with most household appliances.
Read in Detail: How Solar Panel Works?
#2. What is Solar Panel Efficiency?
The efficiency of a solar panel is a measurement that tells you how well a solar panel converts sunlight into usable electricity. Assume the efficiency of a solar panel is 22%, which means it can convert 22% of the sunlight hitting it into electricity.
Solar panel efficiency is determine by several factors such as their brand, type of solar panel, and wiring & busbars, etc. Most panels have an efficiency rating between 15 to 22 percent. High-efficiency solar panels are typically more expensive. However, it is sometimes worthwhile to pay more for panels that produce more electricity.
So if you have limited roof space and are struggling to cover all of your electricity bills with solar, using high-efficiency panels can increase your long-term savings.
5 Points to Remember Before Buying Solar Panel
Solar panels are the main part of all types of the solar system. A complete solar panel system typically includes two or more solar panels, a solar inverter, a solar battery, and other accessories.
Which type of solar panel would be best for you?
By the way, there are not many technologies or types of solar panels in the market. But still, you are not a solar expert. You don’t know which type of solar panel out of monocrystalline, polycrystalline, and bi-facial solar panel will be more beneficial for you. So before buying a solar panel, it is necessary to ask a solar expert that which type of solar panel will be best for you.
Trust a 25 year old brand for next 25 years.
This is one of the most crucial recommendations to keep in mind when purchasing a solar panel. Before buying any solar panel, do a little research. Check the company profile, check the panel’s certificates. The type of testing that has been performed on solar panels is indicated by the certification. For example, IEC 61215 is one of the core testing standards that confirms a solar panel has completed several stress tests and performed well in regards to quality, performance, and safety.
Is solar really beneficial for your location?
Some states in India are far better for solar energy production than others. Surprisingly, we are not talking about the weather conditions in your state here. The weather only plays a very small factor in this because, on cloudy days, solar panels can still generate solar power. It’s your state’s electricity cost more than the weather that determines how much you can expect to save and how soon you can get a return on investment. Also, consider your state’s solar subsidies and their net-metering program.
Always choose a trusted solar brand?
Solar companies nowadays advertisements too much about their solar product to woo people. A lot of people don’t understand in the glare of these advertisements which solar panel they should buy. In such conditions, it is always preferable to seek advice from others. You can inquire from your knowns who already have installed a solar system at their homes or a solar expert. Remember, by buying solar panels, you are going to invest a large part of your earnings for a long time. So you should be careful about which solar panels you want to buy and which are not.
Check, Compare and then Buy.
Of course, the cost of solar panels has been decreasing continuously for the last few years due to the initiatives and schemes of the government. But if you are paying far less money for the same size solar panels available in the market, then be careful. You may get poor-quality panels as well as installation services. Before buying solar panels and other solar components, always do a little research about its current price in the market. Otherwise, it is quite obvious that you get what you pay for.
#3. 3 Types of Solar Panel
The growing demand for solar power is fueling advancements in solar PV technology research and development. There are currently three types of solar panels on the market. These panels are different from each other in terms of their formation, efficiency, and material. Have a look below to learn all about the different types of solar panels.
Solar panel technology has now changed and it’s going to be better as improvements in efficiency, quality, and versatility continue to develop.
Read in detail about: Polycrystalline Solar Panel
Polycrystalline Solar Panel
Polycrystalline solar panels are the most common type of solar panel. These panels are made up by pressing multiple pieces of silicon together. Polycrystalline solar panels usually have a blue mottled look.
The efficiency rate of a polycrystalline solar panel is around 16%-17%. These panels are best to work under extreme weather conditions. Polycrystalline panels are slightly less efficient than monocrystalline but they are cheaper which makes them a popular choice.
Monocrystalline Solar Panel
Monocrystalline solar panels are the second most successful type of solar panel. These panels have blackish-hue on their surface and are made by a single silicon crystal. Monocrystalline panels have solar cells in a more rounded shape with their corners cut off.
Monocrystalline solar panels tend to be more efficient than polycrystalline solar panels. Their efficiency rating is around 19%-20% because the solar cells have high purity. These solar panels are the best solar panels with the best purity and highest efficiency levels.

Read in detail about: Bifacial Solar Panel
Bifacial Solar Panel
Bifacial solar modules offer many advantages over traditional solar panels. Power can be produced from both sides of a bifacial solar panel, increasing the total energy generation. Since more energy is transformed into electricity, fewer panels are required to satisfy the same power requirements in typical roof installations.
Bi-facial solar PV modules are often more durable too because both sides are UV resistant. When bifacial modules are installed on a highly reflective surface they can generate up to 30% more electricity from their bifacial properties.
Click to know: How You Can Earn up to ₹25.5 Lakh by Installing 10kW Solar Panel?
Yes, you heard it absolutely right. You can earn up to ₹ 25,50,000 from a 10kW solar system. Let’s learn how?
There is a thumb rule of solar that as many thousand rupees as your bill comes per month, you should install the same kW of solar system. Now just assume, your monthly electricity bill is ₹10,000/month. So according to this rule, you will have to install a 10kW solar system which will cost you around ₹4,50,000.
Now come to its ROI & working life.
The ROI (return on investment) of solar panel is very quick and you will get your money back within 45 months. If we talk about its working life, then the estimated life of any solar panel system is around 300 months (25 years).
Let’s see the calculation now.
- You invested = ₹4,50,000
- Life of solar system = 25 years (300 months)
- You will get your investment back within = 45 months (45 X 10,000/month = 4,50,000)
Hence, your solar system will generate electricity for extra 255 months (300 months – 45 months) after recovering its cost.
Now if you see, then you are generating worth ₹10,000 of electricity per month. You can sell this generated electricity to the government and earn ₹25,50,000 in those extra 255 months or you can save your own ₹25,50,000 by not paying electricity bills for 255 months (21 years and 3 months).
Monocrystalline V/s Polycrystalline Solar Panel
There are mainly two types of solar panels or modules used in rooftop and ground-mounted installations – monocrystalline and polycrystalline. However, monocrystalline v/s polycrystalline solar panels, both are the best type of solar panels. But often, they create great confusion while it comes to choose the best among them.
Here we have a comparison between both types of solar modules to make the selection process easy.
| Mono Panel | Poly Panel |
| Expensive | Cost Effecctive |
| Efficiency Upto 20% | Effeciency Upto 16% |
| Black in Colour | Blue-ish in Colour |
| Cover Less Roof Space | Cover More Roof Space |
| Better Efficiency in Low Light | Comparatively Low Efficiency |
#4. Solar Panel Price List
The most important factor that influences our mind at the time of purchasing solar panels is the “Price of Solar Panel”. Normally, the prices of panels are measured in solar price per watt. Solar panels are rated by their wattage and efficiency. A panel’s wattage is how much power it is expected to generate.
Investment in solar is big and one-time investment. So if you are going to install a solar panel at your home or business, you should know the prices of solar panels.
