Factors to consider before buying the best solar panels
In this section, we have covered some important factors to consider before buying the best solar panels in India. Fancy advertisements might try to lure you into buying certain solar panels. Do not fall for this trap. Know these important factors, check whether the solar panels you are considering to buy meet the requirements, and only then go ahead to make a decision.
1. Types of solar PV systems:
There are mainly 3 types of solar PV systems – Off-grid, on-grid, and hybrid solar systems. It is important to have a basic idea of how each one functions and operates, so that you know which one will be ideal for your home or office.
- Off-grid solar system – In this, the off-grid solar PV system does not get connected to the primary grid. Its main components are the solar panels, an inverter, power back-up, mounting structures, and the central AC panel. All of this works independent of the entire power network. There are battery banks in this system, where energy can be stored and then used to supply current using a domestic inverter to the household.
If you are living in an area where power cuts are frequent, this power system will be perfect. However, the main electric power system of this solar system is unstable and unreliable.
- On-grid solar system– Unlike the former, this one works along with the primary grid, and does not require power banks to store electricity. If the overall energy consumption is very high at your place, then the on-grid solar system can be of help. You can use this grid during the day to reduce the pressure on the primary grid. This saves on your monthly electricity bills.
- Hybrid solar system– As the name suggests, the hybrid solar system is a combination of the on-grid and off-grid solar systems. It stores energy in power banks like off-grid systems, and connects to the primary grid like the on-grid solar system. Thus, even when there are power cuts at night, you will have a regular supply of electricity with the hybrid solar system.
With this system installed, you can save the maximum amount of money and get maximum efficiency as well. These can be called the best efficiency of solar panels in India.
2. Type of photovoltaic panels:
There are 3 types of solar panels – Mono-Crystalline solar panels, Poly-Crystalline solar panels, and Thin Film solar panels. It is crucial to discuss these three types in a little more detailed manner in this section.
- Mono-Crystalline solar panels– If you are looking for premium-quality solar panels, mono-crystalline panels are ideal. They produce more current as compared to poly-crystalline solar panels. These can be recognized by the single flat black color. Even in terms of efficiency, mono-crystalline panels tend to perform better than polycrystalline solar panels. Single-crystal silicon is used to make the solar panels.
- Poly-Crystalline solar panels– While poly-crystalline solar panels have a low-efficiency rank as mentioned earlier, the reason why many people in India still prefer to buy it, is because they are cheaper. Poly-crystalline panels are blue and that is how you can differentiate them at a glance from mono panels. Due to their affordable pricing, poly panels are widely used for residential purposes.
- Thin-film solar panels– This is a relatively new type as compared to the first two, and is not quite popular in the country yet. Thin-film solar panels are usually black, and they rank the lowest when it comes to efficiency and performance. They come without frames, set in between glasses. This is what makes them flexible. However, these panels occupy a large amount of space which can become an issue, especially in a residential building.
The efficiency of the solar panel is the most crucial aspect. As efficiency goes up, the requirement for the number of panels goes down. The ability of the solar panels to convert sunlight into electricity determines its efficiency and effectiveness. If you have space issues, it is best to look for solar panels with maximum efficiency, as they occupy the least amount of space.
Efficiency tends to reduce if you allow dust and dirt to settle on the panels, and to avoid this, you must clean the panels at regular intervals. Place the panels in a spot that does not get any shadow, as this too can lessen the effectiveness of the solar panels. The tilt of the panels also plays a significant role in determining its efficiency.
3. Temperature coefficient:
Sunlight is the only source of energy that solar panels depend on, but sometimes the heat can get too much for the solar cells. Extremely high temperatures can destroy the cells as well. The efficiency of the solar panel is determined by this temperature coefficient. Efficiency is better when the temperature coefficient is lower.
If the temperature is greater than 25 degrees Celsius, then both power output and voltage drops and the current increases. On the other hand, when the temperature is less than 25 degrees Celsius, both the power output and voltage increase, but the current drops. To reduce the intensity of the sunlight during the day, you can always tilt the panels. The best solar panels available in India are those that come with automatic tilting for this purpose.
4. The durability of solar panel:
Another crucial factor that must be considered before buying the best solar panels in India is its durability. Solar panels are meant to stay outdoors, and they have to tolerate nature’s wrath at every turn. Hence, the solar panel you purchase must have the strength to stand straight through it all. Before reaching markets to be sold off, most solar panels go through rigorous testing against harsh weather conditions.
The testing is done depending on the weather of the country where the panels will be sold, since natural conditions differ from place to place. You can read reviews by other customers in India, or simply rely on a trial and error process to ensure that you buy the most durable solar panel.
5. Solar panel ratings:
The capacity of the solar panel to generate electricity under certain specific conditions is suggested by the solar panel ratings. You can rely on these ratings to make a comparison between different solar panels. If a solar panel shows a high rating, then it means that it creates more electricity than another solar panel with a lesser rating.
However, when two solar panels have the same rating but different power ratings, it usually means that the one with a larger power rating is also bigger. You need to bring in other factors to make the comparison in that case.
6. Solar panel price:
The price of the solar panel is yet another factor that you cannot negate while looking for the best solar panels for home in India. People usually search for panels that give the maximum performance at a low price. However, you must keep in mind that a lower budget might also mean lesser features and lower efficiency. Always check for the quality of components, warranty period, after-sales service, installation charges, etc before buying the solar panel.
7. Solar panel certifications:
Your solar panel must be certified by recognized bodies, as this allows you to get various subsidies and also makes the product trustworthy. It is thus best to buy solar panels that are approved by the MNRE (Ministry of New and Renewable Energy). Only those solar panels that are grid-connected qualify to get subsidies from the government.
8. Manufacturer’s warranty:
Even though we have mentioned this factor towards the end of the list, the warranty remains to be one of the most crucial factors that you must take into consideration before buying the best solar panel in India. It is also the trickiest factor. There are two types of warranties that come with a solar panel – the manufacturer’s warranty, and the performance warranty.
The former covers problems such as durability, manufacturing defects, or certain environmental issues. The manufacturer’s warranty that most brands offer usually ranges from 5-15 years. This warranty covers any damage caused due to environmental disasters like storms, cyclones, and so on.
The performance of the solar panel is expected to degrade every year, and this is called panel degradation rate. The warranty provided by some companies on this degradation is known as the performance warranty. This ensures that the degradation of the solar panel will not be beyond a certain percentage within a stipulated time. Usually, the degradation percentage every year is 0.7%.
9. Power requirement:
You must have a rough estimate of your power requirements before investing in a solar panel. Whatever appliance that you will connect to the solar panels, such as fans, lights, air conditioners, and so on, makes up your power requirement. You must calculate the total load all this might add up to. Further calculations will give you the UPS VA rating, and you can go on from there with a few more calculations arrive at the approximate panel size that will suit your power requirement.
You must make sure that the UPS is compatible with the voltage and the current of the solar array.
10. Check the mounting system:
Mounting systems are the things that keep the solar panels mounted at all times. The mounting system protects the solar panels from getting uprooted during harsh storms – which are especially helpful if you live in a cyclone-prone area. There are mainly two types of mounting systems – the flush mounting and the roof or floor mounting.
The former can be easily installed and is reasonably priced, whereas the latter is more expensive, but it ensures a long-lasting life for the solar panels. The roof or floor mounting system is necessary for places that are prone to cyclones. The panels cannot be kept steady with flush mounting when winds pass through in high intensity.
11. Solar inverter:
A solar inverter is needed when you are fitting solar panels for your home. It converts DC into convertible AC. A premium quality solar inverter will ensure that less energy is wasted at all costs. This will not only save on your monthly electricity bill, but also save the environment from deteriorating so rapidly.
12. Elements in a solar PV system:
Lastly, it is important to have some basic knowledge about the few elements that make up the solar PV system. These are:
- Photovoltaic array– Many solar PV panels together make up a photovoltaic array, and when this receives sunlight, it produces DC voltage. The electric supply can be produced by connecting the panels in a series.
- Battery bank– The mechanism of a battery bank is very similar to that of an inverter battery. It stores all the energy throughout the day to be used when there is a power cut or voltage fluctuation at home.
- Power conditioning unit– This unit is meant for the protection of the solar panels, in the case of short circuits or other faults in the line. The DC supply is also converted to AC by this PCU unit. The input energy received from the PV panel and the output power from the power bank is also controlled by this PCU.
- DC and AC connect– Any technical personnel is protected by this unit from electric shocks at the time of system maintenance.
- The Central Panel (AC)– The load of the entire building falls on the main panel, which is protected from accidents by circuit breakers.
- Electric meter– The electric meter is from where you control the power generation of the panels and also its usage. Electricity is supplied to the primary grid if you ever generate excess energy. With ‘Net Metering’ capabilities, such situations can be easily dealt with.
Frequently Asked Questions
1. What happens to solar power that is not used?
There might be times when you produce more solar energy than you can consume. During such times, the excess solar power is used to charge the grids and keep them in good condition. This reduces the load on the normal electricity usage and helps you save on your monthly electricity bills.
2. Can I run the entire house on solar power?
Running the entire house on solar power will require a higher number of grids, and can become quite an expenditure, because of the various heavy-consumption electrical appliances we use at home. Thus, it is better to use solar power only for a few appliances, or use it as a power backup for times when there are power cuts in the house.
3. On average, what is the lifespan of a solar panel?
Most companies provide a warranty of 20-25 years on the solar panel – which means that the minimum lifespan is that much. However, with electrical appliances, the trick to a long life lies with good maintenance of the product. When maintained well, a solar panel can last for as long as 40 years.
