The renewable energy market is constantly evolving. We already have several options to make our energy consumption even more environmentally friendly. In this article, we want to talk about everything that needs to be considered when choosing the best photovoltaic panels 2020.

How to choose the best photovoltaic panels 2020

If you want to install a photovoltaic panel system in your home to save on your electricity bill, you will find plenty of offers on the market. Some will be cheaper than others, some better than others… but what you want is an offer with good value for money. Then, 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 you can choose inexpensive photovoltaic panels of Asian origin, or of European and American “certified” production, Chinese, Korean or Japanese.

When buying, we don’t look for quality, but we look for price, and we find that the world’s best-selling panels are produced in China. Next come: South Korea, Hong Kong and Canada.

How to distinguish the best photovoltaic panels.

There are no clear benchmarks to distinguish the best PV panels, but some can be taken into account when designing our PV system. Criteria that will allow those who do not have adequate technical knowledge to make the best choice.

Today the market has a wide variety of options, it is more and more 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 experience to unravel the complexity. subject technique.

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 the photovoltaic panels are, the more energy they produce, the better their efficiency and over time, the investment will pay off more quickly.

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 classified as 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“. In the beginning, virtually all photovoltaic panels generate the energy they should, when 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 energy for at least 20 years, with the replacement of the inverter every 10 years. Even taking this into account, it’s enough to remember that all panels experience a drop in performance over time, an estimated loss of around 1% per year.

Therefore, good quality photovoltaic panels, good quality inverters, allow the investment to pay off faster in the long run.

Yes the efficiency of photovoltaic panels guaranteed over the long term it will be essential for the choice of the panels of your photovoltaic installation.

In the market we will find several brands, some cheaper (Chinese and Asian) and others more expensive, apparently better, 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
Efficiencyandncia (%) 14% 22%
Maximum power 200 W 315 W
Maximum voltage 28 V 40 V
Type of technology Monocrystalline silicon, polycrystalline silicon, amorphous silicon
Number of cells 60 96
Product warranty 5 years 10 years
Performance Guarantee – 90% 10 years 12 years
Performance guarantee – 80% 15 years old 25 years
Weight resistance 5400 Pa
550 kg / m2
8500 Pa
860 kg / m2
Wind resistance 2400 Pa 2400 Pa
Temperature coefficient (% / ° C) 0.20 0.40
Operating temperature -40 ° C +85 ° C
Equipment Heat-tempered glass Non tempered glass
Structure material Other material Galvanized aluminum
Length (mm) 910 1295
Height (mm) 1600 1955
weight (kg) 18 36
Width (mm) 30 60

Without going into overly technical considerations, we can say that some of these criteria are useful in helping to distinguish the quality of one photovoltaic panel from another.

The most correct is to talk about indicators and not 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 always present the panels, solutions compatible with the connection to the network. And there are those who distinguish between the best deals, it’s the aspects that make the difference.

Better products also have slightly higher costs, and of course higher costs usually equate to better quality and good warranties.

Indicators for choosing the best solar panels.

Experience is synonymous with manufacturer reliability. A point to keep in mind, before even looking at 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 guarantee of first-rate quality.

Because a well-structured production guarantees solid technical support and long-term assistance, 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 should choose the one that sells the best. Because in the global 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 among the best-selling brands of photovoltaic panels in the world in recent years, we find: Jinko Solar, Trina Solar, Canadian Solar, Ja Solar, Hanwha Q-Cells, GCL-Si, LONGi Solar, Risen Energy, Suntech, Yingli Green , First Solaire, Renesola, Sharp and SunPower.

Therefore, if in doubt, you should choose photovoltaic panels from these brands.
