Outdoor applications of solar panels are ubiquitous and its lifetime can last up to 30 years or more, especially solar systems installed on the rooftop or on the ground. The obverse side of the solar panel has to expose to rainy, wet or any other heavy weathers, so they should not break, short circuit, etc.

Since we use the solar panels outdoors, then everyone will have such a question, are solar panels waterproof?

First, we need to understand the structure of the solar panel. It is mainly composed of solar cells and related laminated materials. The solar cell is not waterproof, because it has circuits and wires on its surface. If some water is on the cell, short circuits will occur. The cells will be damaged, etc. But do not worry, the solar cells are encapsulated in laminated materials or in some special resins.

Therefore, the waterproofing function is mainly reflected in the outer laminated technology and edge treatment. Generally, we use the solar panels in the large on-grid system are basically covered by tempered glass, and the glass material is waterproof. And the back sheet is usually made from a durable polymer-based material. That means the solar panel has to be waterproof in order to keep producing power for more than 30 years. There are also some other materials besides tempered glass, such as PET, ETFE, which are also waterproof.

So, do not worry, your solar panels are waterproof.

If your solar panel is still under warranty, and if rare water damage occurs, the manufacturer or the brand company will take it. And sometimes, your solar panel manufacturer will not only pay for the new panel but also will pay for shipping and reinstallation. Most equipment is warranted for more than 10 years.

There are some best sellers on Amazon and eBay.

12V Flexible Water proof Solar Panel

This 20 Watt 12 Volt semi-flexible solar panel is made from the highest efficiency solar cells that can up to 23.7%. Lightweight and bendable.

Waterproof Solar Panel Car Battery Charger

I must say it is the best solar car battery charger for drivers. Comes with alligator clip and Car mounted charger makes you can go anywhere you do!

Waterproof Solar Backpack

Built-in 7 W solar panel with USB port, a must have for any outdoor enthusiast and business traveler.

Solar panels are not only waterproof – but also protect against most weather-related stresses. There is no need to worry about snow in cold climates, and solar panels can withstand considerable weight without collapsing. The colder weather can even increase the production of solar energy. Even extreme weather such as hurricanes and hail storms will not have much impact on solar panels – because of the proper shelf systems prevent strong wind damage, and durable glass makes it can be used in most hailstorms.

The type of damage determines the solar panels repair

Colloquially is often spoken of “repair solar cells”. The exchange of individual solar cells in the panel is possible, but not really economical. People always speak of solar panels repair, but, whether this is possible, it determines the type of damage.

Inner module damage

Internal damage is a problem where there is no external impact such as a storm has caused damage to the solar panels. These problems can be caused by a faulty production or a poor selection of individual or all components. Unfortunately, a solar module repair is usually not possible in these cases.

– Snail trails

– Delamination

– Hot spots

– Discoloration of solar cells or cell connectors

– Discoloration of the EVA film (Browning)

– Discoloration of the backsheet (yellowing)

– Different colors of solar cells/cell staining

– Inclusions in the laminate

– Scorched on the front and/or back

Module damage due to external factors

This type of damage happens during weather reasons in most cases. Storm, hail, lightning and over voltage or snow pressure can damage a solar module, but also fire, excessive heat or an animal bite could cause damage as well. The advantage of this damage is that you can often repair it. But with the external damage already decides the strength of the damage on the potential success of the solar panel repair.

Flying pieces, broken branches, hailstones the size of tennis balls and collapsed buildings. Storms often cause a huge damage to solar panels. The consequence:

– Glass breakage

– Micro cracks and cell breakage

– Scratched module frame

But even cold, snow and ice can clog the solar panels. In addition to the solar glass breakage module, the solar panel frames will be twisted or frozen after a long and cold winter.

However, the most common cause of solar panels repair is lightning and over voltage. Direct or indirect impacts near a solar system can break a PV module. The big advantage with these modules is that you can repair these solar modules. The lightning and overvoltage will cause the following damages:

– Burned junction boxes

– Defective bypass diodes

Small animals make big damage. Small martens, rats, and mice regularly cause damage to large solar systems. The little rodents are less concerned with the glass modules than with the connections and often leave an animal bite on solar cables and solar plugs.

Solar panels exposed to fire are often not salvageable. In addition to the flames but also the enormous heat can be a problem. The strong heat can damage the solar system, and the solar panel will be surrounded by scorched materials.

What can be repaired on a solar module?

You can fix a lot but not everything on a solar panel. It should always distinguish between the solar panels repair on site and the repair in a special repair center.

The repair on site is limited in all the line to the replacement of defective bypass diodes in the junction boxes. But even broken and bruised solar cables and plugs can be replaced. However, if the damage is very bigger, you can not avoid letting a special repair center to do that.

Solar panel repair by a specialist

A repair center specializes in photovoltaic module repair. Among other things, it is possible to replace scorched junction boxes. The old box is carefully detached from the module and then a new box is placed on the back of the module.

There is also the possibility in the workshop of replacing the frames on the modules. The old bent or split module frames are simply replaced with new ones.

Another benefit of Repair Center repair is that the modules undergo extensive testing after repair. In addition to an insulation test, a power measurement is always carried out. Through the so-called flash test, the current module power in watts peak can be determined. In addition to a flash test, an electroluminescent image is often also created. This cell breaks and micro cracks in the modules can be detected.

Can you repair solar panel glass breakage?

There is no economic way to repair broken and cracked solar modules, and the maintenance cost is very expensive. But there are many hobbyists who repair modules with glass breakage. With resin, silicone or other agents, these try to seal the surfaces. We do not recommend using such repair modules in photovoltaic systems because of the maintenance cost. As hobby modules for camping or in the garden, there is certainly still a meaningful use.
