Solar panels and PV+Test
Today, the only one 100% independent test that makes tests on the solar panels that are reached by the end customer is the PV + Test, made by the German certifier TÜV.
Taking into consideration, the classification of this test is vital to have the security that your photovoltaic system will obtain the expected performance, among other things.
Some of the 11 brands of solar panels that have authorized, for the moment (2016-2017), the publication of the results of the PV + Test are: SolarWorld, SHARP, Solon, Schott, Conergy, Sovello …
The result of the tests of the best solar panels, in order of maximum quality are:
||Schott Poly 290
||IBC Monosol 240 ET
It is no coincidence that there is almost no absolute lack of Asian solar panels brands, the vast majority of Chinese / Asian brands do not achieve the minimum quality required.
The PV + Test scores range from the highest grade, which is Excellent, to Very Poor. In each grade, depending on the results, you can carry (+) or (-) as intermediate grades.
Undoubtedly, the PV + Test, should be a very point to consider when defining the pv module to install in a pv system.
In response to the question of What is the best solar panel in the world? It is very evident, the best solar panel in the world is SolarWorld, followed closely by Schott and SHARP Solar.
We should also bear in mind that we are talking about the best solar panels on the market with standard polycrystalline and monocrystalline technology. If we expand the vision to any type of technology, we would find that the best solar panel on the market would be Panasonic Sanyo solar panels, with high efficiency HIT technology.
In other words:
If we look for the best panel in the market using standard technology, the most outstanding is SolarWorld. If we look for the best panel of any technology, then Panasonic Sanyo would be the most outstanding. They are the two best solar panel brands that we can find today in the solar photovoltaic market.
