Buying Guide for Solar Panels
We have already seen the different parts of a solar system. We have also discussed in brief about the functionalities of each part.
Costs wise, the solar panels consists of 50% of the overall cost of installing the panel.
The battery and inverter will make almost 30% of the cost. The other major components, like wires, mounting structures and junction boxes contains the remaining cost.
Solar panels – The components
As we already discussed above that Solar panels are made up of solar cells.
For making a Solar PV system, it requires connections, laminating, taping, installing junction box and testing.
Glass: It protects the solar module or cell from any damage
Encapsulant: It is the most important part that give adhesion in middle of the solar cells, the bottom and top surfaces of the module. It should be transparent while having low thermal resistance.
Frame: It is placed for providing protection to outer layer
Solar Cells: The main work of absorbing sunlight and converting solar energy into electricity happens at this point.
The Junction box: Junction box consist of wires that helps in transporting the electricity from the solar panel to the power conditioning unit.
Back sheet: It provides extra support to the entire module.
How do they work?
Solar panels absorbs the sunlight that falls on it all over the day. Higher sun intensity means electrons will contribute more to the flow of current.
Major purpose of solar panels is to convert solar energy into electricity. One can store this energy into batteries for use at later stage.
Various Kinds of Solar System
In India you will find two kinds of solar systems in the market.
On-grid solar system
On-grid solar system works with the primary grid of your home. In On-grid solar system you can not store the electricity in the batteries.
On-grid solar system are used in those places where consumption of electricity is very high.
On-grid solar system altogether saves you from paying a huge amount of electricity bills. As it is connected to your primary grid, in day time the electricity consumption will be used from solar panel only.
Off-grid Solar System
Off-grid solar systems are not connected to your primary grid. Off-grid solar system consists of wires, solar panels, inverter and the central AC panel.
Off-grid solar system helps in storing the electricity in the batteries that can be used later to provide electricity to the household using the inverter.
This kind of solar systems are mainly used in those places where power supply is irregular. It is used in those places where power cuts is the new normal for public.
Hybrid Solar System
Hybrid solar system is a combination of On-grid and Off-grid solar systems.
Hybrid solar system can be connected to your primary grid also and can store electricity in batteries and inverters like Off-grid also.
In night the electricity that is stored in the inverters can take over at provide enough electricity. In many cases, people have experienced that, they are having surplus energy.
Hybrid solar system can easily provide you enough electricity in the day that you don’t need it from you primary grid.
Types of Photo Voltaic panels
There are two types of photovoltaic panels that is majorly used in India.
Poly Crystalline or Multi Crystalline Panels
This kind of panels comprises of several crystals of silicon in a single PV cell. The method of manufacturing the poly-crystalline panels are manufactured by melting various fragments of silicon together to form the wafers.
Mono-crystalline panels stores cells that are cut from a single-crystalline silicon. While manufacturing the mono crystalline panels, those silicon is found in bars and cut into wafers.
Mono crystalline panels are very expensive in comparison to others, highly efficient in comparison to others.
This kind of panels consists of Amorphous crystalline, Copper Indium Gallium Selenide (CIGS) solar cells. These panels are not efficient compared to above mentioned photovoltaic panels.
These type of panels are not available in the Indian market because of its less efficiency. Mainly, Office or household PV systems use the mono-crystalline or the poly-crystalline photovoltaic cells.
Things to Consider before Buying solar panels
Investing in a domestic solar PV system is a once-in-a-lifetime decision. It involves a lot of money.
Therefore, it becomes necessary to consider the following factors when shopping for solar panels.
We shall touch upon metrics like efficiency, tolerance levels, temperature coefficient, durability, and warranty that will decide the number of solar panels required for your home solar PV system.
It will also help you choose the right vendor. We endeavor to help the layman buyer become technically knowledgeable so that he/she chooses the right brand.
A lot depends on the efficiency of the solar panels. The higher the efficiency, the lesser is the number of panels you need for your solar PV system.
The effectiveness of a solar panel depends on how much sunlight it can convert into electricity.
Let us now go through the mathematical calculation of the efficiency of a solar module.
The area of a solar panel is roughly 2 square metres. If we exclude the space occupied by the frame, it comes to around 1.95 square metres.
Let us now consider the efficiency of a 350W Loom solar panel (one of the best brands of solar panels in India). Other panels have different efficiency levels.
Under ideal conditions, a 100W solar panel should deliver an output of 100 Watts. However, there is a concept of tolerance level.
The manufacturer advertises a tolerance level of +/- 5%. Therefore, the output of the panel will be in the range of 95W to 105W.
A positive tolerance level is acceptable, whereas a negative figure is not.
Note that you should always go for a solar panel that mentions a positive tolerance level.
Solar panels require sunlight for its operation. However, one should note that solar cells can get extremely hot.
High temperatures can lead to degradation of the cells. The temperature coefficient is a crucial factor that decides the efficiency of a solar panel.
The durability of the Solar Panel
The solar panels are outdoor appliances. Hence, they have to bear the brunt of nature, such as heavy rains, wind, pressure, temperature, hailstorms, and so on.
Usually, the panels go through strenuous tests depending on the different types of environmental conditions before being certified for use in a specific country.
For example, a solar panel approved for installation in India will be different from the one in the UK. As a consumer, you should opt for panels that are certified as fit for use in your respective country.
Rating agencies compare these panels and assign individual ratings. In India, we shall look at some of the top solar panels.
Warranty provided by the manufacturer
Based on the durability of the panels, the manufacturers offer attractive warranties. Solar panel manufacturers face tremendous challenges in their business, such as declining prices of the products and the effect of Government regulations.
The smaller players can find it challenging to sustain their growth. Hence, they offer lesser warranties. The brand-conscious buyer goes for the ideal brand that offers the highest efficiency, durability, and the maximum warranty.
Cost of a Solar PV System
In India, an off-grid 1KW solar PV system should be available in the range of Rs 1 lakh to Rs 1.25 lakhs.
If you opt for a grid-connected solar system, the costs should be in the range of Rs 60,000 to Rs 1 lakh.
