If you are capable of making one-off initial investment into rooftop solar system to meet your electricity needs during power-cuts or as an alternative to what is supplied by the state power grids and thereby cut the cost on your utility bills, it is worth the investment.
What stops people from using it is the Rs.70 per Watt they have to spend in order to install this system and connect it to the grid. The good news, according to the Ministry of New and Renewable Energy, is that the Government of India has subsidized the use of this system by 30% and around 70% in certain states like Uttarakhand, Himachal Pradesh, Sikkim, etc.
Another thing, India is so geographical positioned that the major part of a year remains sunlit. Hardly there are areas where overcast weather conditions are experienced outside monsoon. This particular fact is one of the biggest reasons why such a system is advantageous over a long period of time in India.

The Best Solar Panels in India 2020 – A Buying Guide
Solar panels are one of the ways in which power is generated for domestic or commercial consumption at times when there is shortage of power.
Having said that, it must be added that it is certainly better than home inverters and generators. This is because the home inverters often have to struggle with the load depending on the kind of appliances and the amount of energy they consume.
As for the generators, they are surely not a cost-effective solution for a power-cut situation. That is because they need a lot of fuel. On the other hand, solar panels have a number of advantages when compared to the other two options:
- It runs on energy that is drawn from the sunlight. In other words, as long as the sun rises on this earth, solar panels will continue to have inexhaustible source of energy that they may convert into electricity. And, this energy is also renewable
- Though you have to spend some money upfront to buy the solar panels, their operating cost is zero. It does not require maintenance in the way that home inverters do. For instance, if the home inverter battery is dead, you may have to spend as much money as would supply half the cost of brand new solar panel. That’s something, isn’t it? Problems like burnt-out rectifiers, too, are costly
So, we may fairly say that the very concept of using solar energy for generating electricity has a lot of insight and also foresight in it. This is because the source of energy is continuously getting depleted on planet earth.
It is not for nothing that the nations are vying with each other in order to command the natural resources of the earth. So many territorial and international waters disputes are rooted in this particular problem. They know all too well how badly the world is going to face the dearth of energy resources in the time to come, and how profoundly it is going to impact our highly technologized civilization. That, also, is the reason why all of them are desperately trying to come up with alternatives of different kinds of energy resources.
Therefore, the solar energy could be viewed as a ray of hope in the dismal situation that the world is facing in future. This brings us back to consider in depth the use of solar panels and the advantages it offers.
While the use of solar energy began roughly hundred years back, the idea of employing solar panels for the purpose was made possible only after the discovery of photovoltaic effect in 1839 which brought to birth what is now called photovoltaic cell or solar cell.
A photovoltaic cell is made from semiconductor materials. Solar panels comprise of such cells. Generally, the materials used in making these cells include n-type and p-type silicon, phosphorous and boron.
What this photovoltaic cell does is to absorb photons and convert their electromagnetic energy into electricity. This method was first used in space satellites. People had first-hand experience of the efficacy of the solar cells through their calculators.
One great advantage of solar panels is that the extra energy is saved in the electric grid during the day time, and the same can be used during night.
Types of Solar Panel
There are three types of solar panels available in the market:
- Monocrystalline: Its solar cells are made from a single crystal of silicon. These cells are arranged in rows and framed in a rectangle frame which is largely made from aluminum. The surface of this panel, and also of the polycrystalline, is coated with glass. These panels are black-colored and having back sheets which are either black or silver or white.
- Polycrystalline: This type of solar panel is made from silicon crystals melted and formed into thin plates. In other details it remains the same as the monocrystalline solar panels. These panels are blue-colored having back sheets which are silver or white. You may consider it to be a disadvantage that it requires greater area for installation.
- Thin-film: This type is made from cadmium telluride or amorphous silicon or copper, indium, gallium and selenium. Those which are made from cadmium telluride have it formed into a layer that is inserted between conducting layers. Those made from non-crystalline silicon have it applied on the glass, plastic or metal surface. When they are made from CIGS, these four metals are placed between two conductive layers. These are either blue or black.
Since the climatic conditions greatly affect the durability of the product, you need to know whether it has passed IEC standards. For the rest of India the relevant certifications include IEC 61646 and IEC 61215 or IEC14286. If you are living in a coastal region, you MUST ensure that the product of your choice has IEC 61701 certification.
These solar panels are further differentiated in terms of how they are connected to the power grid. Some form a system that is grid inter-tied; some form a system that is not only grid inter-tied but also supported by battery backup; and some form a system that is off-grid. It is up to you to decide which one you want to go for.
Potential Induced Degradation (PID)
Before finalizing the purchase, it is advisable to do some research to find out whether the panels are resistant to Potential Induced Degradation (PID) or not. This is because PID may seriously affect the capacities of modules in course of time.
These systems are designed to keep stored energy from getting drained with the help of diodes which come pre-installed with the junction box. It makes power unidirectional, that is, flowing into the battery. So, you expect the junction boxes to feature varying numbers of diodes.

Understanding the Specifications
Now, let us turn to how you can select the best solar panel for all your needs. This involves understanding the specifications of any given solar panel in the right way. Not all would like to get into a number of technical considerations involved in it; but for the sake of those who are more fastidious, we shall try to offer some help here.
- Efficiency of a solar panel: In order to learn about the efficiency of a solar panel you have to use the following formula: Output power per square meter/Input power per square meter x 100. The result of the calculation produces a number that shows efficiency percentage. If you don’t want to get into the technicalities of all this, it suffices for you to limit yourself to learning the cell conversion efficiency. The greater it is, the better it is. Simple!
- Open circuit voltage (Voc): This shows the number of modules in one string that connects certain number of solar cells in a series wired to the charge controller. To leave aside the technical side, you have a voltage specification that gives you the number when the panel is tested under standard conditions. You must understand that these standard conditions do not remain the same everywhere. The specified voltage shows the optimum voltage produced by the panel when it is not have a load. The performance varies in keeping with climatic conditions.
- Short circuit current (Isc): This shows how many amperes the panels produce when not connected with a load.
- On-grid & off-grid: The on-grid system is tied to the grid so that the electricity it produces is channeled to the grid. Your home appliances and other electrical goods derive their energy resources from this grid. If your system generates more power, it goes to the grid.
The off-grid system is not connected to the grid but rather stores the energy it produces into batteries.
- Anti-reflective coating: This is provided with the help of films which are made from SiO2(1), TiO(2), silicon nitride (SiNx) (3) and boron nitride (BNx). Their spectral analysis shows that they are quite stable, having wide band gap energy. To put it plainly, they are low reflection materials. It means that the panels having such a coating draw maximum energy from sunlight.
Having talked about the technical aspects of the solar panels, it is time now to ask yourself the question: Which solar panel will meet your requirements? The more you expect from it, the higher the cost and specifications involved in it.
Your requirements could be:
- Cutting cost on energy consumption in the long run
- Earning few bucks for contributing extra energy to the grid
- Utilizing the system to ward off the inconvenience that you stand to experience during power shortages. As it is, this system utilizes the sunlight to source energy for your utility. The sunlight is one of the sources of renewable energy which is inexhaustible. It is simply not possible that you run short of it
Now suppose if you have already made a purchase and its utility proves that you need more out of it? Your battery bank simply does not have the capacity to offer the output you require. In this situation, you do have a solution in the form of MPPT charge controller that considerably boosts the voltage output. Here’s where the disadvantage of traditional PWM charge controller comes to the fore.
