The renewable energy market is constantly evolving. We already have several options to make our energy consumption even greener. In this article we want to talk about everything that must be taken into account when choosing the best photovoltaic panels in 2022.

How to choose the best photovoltaic panels 2022
If you want to install a photovoltaic panel system in your home to save on electricity bills, you will find many offers on the market. Some will be cheaper than others, some better than others… …but what you want is value for money. Next, How to choose the best photovoltaic panel?
It should be noted that the solar panel market is at its peak, with a wide variety of choices.
Currently one can choose cheap photovoltaic panels of Asian origin, or “certified” European and American, Chinese, Korean or Japanese productions.
At the time of purchase, we look not so much for quality, but rather for price, and find that the best-selling panels in the world are produced in China. Next are South Korea, Hong Kong and Canada.
How to distinguish the best photovoltaic panels.
There are no very clear benchmarks to distinguish the best photovoltaic panels, but some can be taken into account when designing our photovoltaic system. Criteria that will allow those who do not have the appropriate technical knowledge to make the best choice.
Today the market offers a wide variety of options, which makes it increasingly difficult to choose the best photovoltaic panels or the best value for money, especially for those who do not have a great knowledge of the market. and a minimum of experience to unravel the complexity. technique of the subject.
The best photovoltaic panels.
A good quality/price ratio, and the choice of the best photovoltaic panels, will determine the success of your investment, because the more reliable and better quality the photovoltaic panels, the more energy they will produce, the better their performance will be and over time, the investment will recover faster.
The choice will always be influenced by the efficiency of the panels and their efficiency over time. A photovoltaic panel that does not produce the expected energy can be called poor quality. While a panel that produces constant energy over time will allow you to recover your investment, and reduce your electricity costs.
Therefore, the key point”over time“. It is that at the beginning, practically all the photovoltaic panels generate the energy which it is necessary, when they are new. Only the best photovoltaic panels continue to produce energy fairly over timeeven after several years.
A good photovoltaic system must be able to produce electricity for at least 20 years., with the replacement of the inverter every 10 years. Even taking this into account, remember that all panels have a reduction in performance over time, an estimated loss of around 1% per year.
Thus, good quality photovoltaic panels, good quality inverters, allow the investment to pay for itself more quickly in the long term.
Yes the efficiency of photovoltaic panels guaranteed over time It will be essential for the choice of panels for your photovoltaic system.
In the market we will find several brands, some cheaper (Chinese and Asian) and others more expensive, apparently of better quality, European (German, Spanish) and American. So what really matters is the performance guarantee.
We see some criteria to consider to distinguish the best photovoltaic panels:
Minimum | Maximum | |
Efficiencyandence (%) | 14% | 22% |
Max power | 200W | 315W |
Maximum voltage | 28V | 40V |
type of technology | Monocrystalline silicon, polycrystalline silicon, amorphous silicon | |
number of cells | 60 | 96 |
product warranty | 5 years | 10 years |
Return Guarantee – 90% | 10 years | 12 years |
Yield Guarantee – 80% | 15 years old | 25 years |
resistance to weight | 5400Pa550kg/m2 | 8500Pa860Kg/m2 |
Wind resistance | 2400Pa | 2400Pa |
Temperature coefficient (% / °C) | 0.20 | 0.40 |
Operating temperature | -40°C | +85°C |
Material | heat-tempered glass | untempered glass |
structural material | other materials | Galvanized aluminum |
Length (mm) | 910 | 1295 |
Height (mm) | 1600 | 1955 |
weight (kg) | 18 | 36 |
Width (mm) | 30 | 60 |
Without going into too technical considerations, we can say that some of these criteria are useful to help distinguish the quality of one photovoltaic panel from another.

The fairest thing is to speak of indicators and not of criteria, that is to say useful indicators to take into account when it comes to a company that offers us its best photovoltaic panels.
There are also technical characteristics that the panels always present, solutions compatible with connection to the network. And there are those who distinguish between the best offers, it is the aspects that make the difference.
The best products also have slightly higher costsand of course the higher costs usually correspond to better quality and good warranties.
Indicators for choosing the best solar panels.
Experience equals manufacturer reliability. A point to take into account, even before seeing the technical characteristics of the type of photovoltaic panel. For a good brand, reliable, internationally recognized and with a history behind it, it is a sign of superior quality guarantee.
Because a well-structured production guarantees solid long-term assistance and technical support, since a panel should last between 25 and 30 years.
The best-selling photovoltaic panels are also the most reliable. If you have doubts between two products, you must choose the one that sells better. Because in the world market for photovoltaic panels, there is no doubt that the largest producers and distributors are those who can offer the best guarantees on their products.
And some of the best-selling photovoltaic panel brands in the world in recent years include: Jinko Solar, Trina Solar, Canadian Solar, Ja Solar, Hanwha Q-Cells, GCL-Si, LONGi Solar, Risen Energy, Suntech, Yingli Green, First Solar, Renesola, Sharp and SunPower.
Therefore, if in doubt, you should choose photovoltaic panels of these brands.
