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.

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 post Are You Looking for Waterproof Solar Panel? appeared first on Hovall.

Why we make it folding? Everyone knows that most of the existing solar panels are coming with the fixed-planar structures, we usually install them out of doors or on the roof of the house. After installing the solar panels, they are basically fixed in position and cannot be disassembled, especially in the case of severe weather or relocating, the solar panels cannot be recycled in time, because it easily damages the solar panels and causes huge economic losses. So for the convenience of use, there are many foldable solar panels that are used in different applications on the market.

How to choose the right power Foldable Solar Panels?

Let us try to choose a solar panel to power a 6 watt device for 5 hours a day, we first do a math that the 6W device will consume 5 x 6 = 30 watts each day, so the solar panel will need to produce 30 watts per day. Let’s assume six hours of sunlight so the solar panel needs to generate 5W per hour, consider the loss of the solar power, so a 6 watt solar panel will do the job. There are many devices and many watts to choose from, here are some best sellers on the market.

200 Watt Foldable Solar Panel

The power of this solar panel is 200W, unfolded size is very large, it looks like a blanket, but it can be put into the backpack after folded.

300 Watt Foldable Solar Panel

300W is too large but it is good to have it as a part of solar systems for home use. It is suitable for TV, Small Air Conditioner, Refrigerator, Electric Cooker, etc.

How to choose the right voltage Portable Foldable Solar Panels?

To select a solar panel to power a 3.7v mobile phone, first of all, you need to know the battery specifications of your mobile phone, the usual mobile phone voltage is 3.6v-4v so we choose the 5V output to charge this mobile phone, in the same way, we use 18v solar panels to charge a 12v battery. For larger solar panels, you need a solar regulator or solar controller to control the current, or it will cause damage to your battery, the solar regulator will ensure the battery is not overcharged all you need is the sun to produce clean and free solar energy.

Foldable Solar Panel 12V

12 Volt solar panel is good for charging 6-9V devices, such as Lamps, LED Lights, etc.

18 Volt Foldable Solar Panel

18v solar panel is good for charging 12v lithium and lead-acid battery, such as laptops, tablets, etc.

The post What is Foldable Solar Panel? How Does Foldable Solar Panel Work? appeared first on Hovall.

What are mini solar panels?

Mini solar panels are small panels that produce solar energy, getting free power from the sunlight and make it supply power to an application or a product. Usually, the mini solar panel is portable and easy to use, it can be used in some applications that larger panels are not very practical or necessary, small size is also one of the most advantages. There are 5 things you should know about mini solar panels.

1, Free Power

The mini solar panel offers a source of renewable energy, as such, they offer an alternative to electricity assets that have environmental expenses, for example, the emission of greenhouse gases. Even though mini solar panel would possibly prove high-priced to buy, solar power saves money on electricity bills over the longer term because there is no money to pay for the daylight that they use to generate power.

2, Size

As the name suggests, the mini size solar panel offers a small advantage over bigger solar panels. A mini solar panel is very easy to carry and use, it has got a versatility that large, bulkier solar panel cannot offer. A mini solar panel can easily be packed and brought on trips, whether or not on an aircraft or on a camping experience to a far-flung spot without electricity.

3, Types

There are two main types of mini solar panels in the markets, one is Epoxy Mini Solar Panel, and the another is Laminated Mini Solar Panel. Laminated Mini Solar Panel has an advantage in terms of product life, and the service life is basically more than 3 years, but most mini solar panels on the market are epoxy mini solar panels because of its simple production process, cheap raw materials, and very beautiful appearance.

4, Limitations

The mini solar panel does not generate enough electricity to perform devices that require a very big power, such as the air conditioners, refrigerators, water pumps. Even for plenty smaller gadgets, inclusive of television and washing machine, mini solar panels aren’t yet reliable as a sole power supply, but it needs to work in conjunction with a battery. In addition, energy interruptions are not unusual in devices with mini solar panel because overcast days can sever access to the solar power supply.

5, Applications

Mini solar panels are flexible strength assets for smaller devices that don’t have robust energy needs. For example, to charge the remote controllers, radios, cameras, fountains, flashlights, and watches. Some applications, which includes cellular phones and laptops, combine mini solar panel with batteries. It takes in electricity from the sun that they distribute to the batteries, recharging them to preserve to function the devices.
