Solar Panel Tongwei 620W Bifacial Dual Glass | Twmnh-66hd620

Industrial power and Bifacial Technology: The Giant of Tongwei in Tienda Solar

Panel Tongwei twmnh-66hd620 It has been developed to lead the high power market. Thanks to cell technology TNC (Tunneling Oxide Passivating Contact) of type N, this module manages to minimize losses by recombination and maximize electron flow, offering stunning 620w of nominal power. Is the most advanced technical solution you can find in Tienda Solar To optimize the space in large covers.

Maximum performance with Dual Glass technology

The architecture of Double glass (2.0mm front + 2.0mm rear) It provides exceptional protection against the most aggressive environmental agents. When you dispense with the plastic backsheet, the panel is totally sealed in front of moisture and extremely resistant to corrosion by ammonia or saline fog. This structural robustness allows you to withstand snow loads of 5400 pa and winds of 2400 pa, guaranteeing the integrity of your Structures for Solar Panels Even in extreme climate environments.

Advantages of bifiality and type N

As a module Bifacial, the Tongwei 620W takes advantage of the albedo or reflection of light on the back surface, achieving a 80% bifiality. This means that it can generate an extra considerable energy, especially if it is installed on clear floors or on high structures. Also, being No-type, the panel eliminates the risk of light-induced degradation (LID), maintaining a much higher linear production than traditional P-Type panels. On Tienda Solar We guarantee that this module will maintain its operational efficiency for decades, supported by a power guarantee of 30 years.

Thermal optimization and versatility

With an excellent coefficient of temperature -0,28% / ° C., this module is able to produce more energy in the hours of maximum heat, loading your lithium batteries More efficiently than other panels in your category. Its media cell design (Half-Cell) reduces internal shadows and improves tolerance to partial shading, which makes it perfect for configuring any Photovoltaic Solar Kit High efficiency.

Frequently Asked Questions (FAQ)

1. Is this panel suitable for residential use in Tienda Solar? Due to its large size (2.38 meters) and weight (32.5 kg), it is recommended primarily for industrial buildings, solar orchards or spacious covers with Reinforced structures. For small homes, we usually recommend 400-500W more manageable models.
2. How much extra energy does it produce through the back face? Depending on the surface (white, gravel, sand), it can generate between a 5% and 25% more of the nominal 620W, which makes it one of the most productive panels of the catalog of Tienda Solar.
3. What maintenance does this double glass module require? The glass is very resistant to abrasion. It only requires cleaning with Fresh water and a soft cloth To prevent accumulated dirt from reducing the efficiency of 23.0%.
