How to Choose a Small Solar Panel That is More Suitable for Your System?

Stand-alone solar panels are widely used in various industries such as remote telemetry, security, monitoring, fence charger, gate opener, intelligent traffic, senor, IoT and aviation obstruction lights, especially with the improvement of solar cell conversion efficiency and the decrease in the cost per W of the solar panel will inevitably further expand the application range of custom shaped solar panels. How should we choose the solar panel suitable for our system?

1. If the product needs to be placed in harsh environments on the sea, desert, wetland, etc. for a long time, we recommend using glass solar panels. Because glass has the advantages of high light transmittance, hard texture and stable physical and chemical properties, it can well protect solar cells from being oxidized and crushed. However, the disadvantage of glass solar panels is that the unit weight is heavier than other types of solar panels of the same power and the glass is fragile. It is not suitable for products that need to be carried and transported for a long time, but is suitable for stationary systems. At the same time, we recommend that the solar panels be sealed with glue or silica gel, so that the life of the solar panels can be greatly extended.
 
2. If solar panels are used in consumer electronics, such as outdoor camping, solar chargers, GPS trackers, etc., we recommend using non-glass laminated solar panels, such as rigid solar panel, semi-flexible solar and fully flexible solar panels and foldable solar panels. Currently popular packaging materials are PET film and ETFE film. PET film is made of plastic. If this material is placed outdoors for a long time, its surface will become brittle and atomized. If a layer of coating is added to the PET surface, this coating will fall off after about 0.5 years, making the surface of the solar panel very unsightly and greatly reducing the power output of the solar panel. If the surface of the solar panel is ETFE film, its lifespan will be longer. We generally think that its lifespan may last 3-5 years. However, such non-glass-encapsulated solar panels must avoid impact on the surface and squeeze around them to avoid damage to the solar cells inside and affect the power output of the solar panels.
 
Sort by low-light performance of solar panels:
Thin-film Solar Panel> Mono PERC solar panels> Traditional Monocrystalline Solar Panels> Polycrystalline Solar Panel.
So solar panels are used in indoor environments, we recommend thin film solar panels. If it is used outdoors, but the light is not very good, you can consider PERC Mono solar panels and traditional mono solar panels. If it is used in a well-lit outdoor environment, you can choose PERC mono, traditional mono and poly solar panels.

Sort by solar panel conversion efficiency:
Mono PERC solar panels> Traditional Monocrystalline Solar Panels> Polycrystalline Solar Panel> Thin-film Solar Panel.
At present, the highest conversion efficiency and large-scale commercial use are Mono PERC solar panels, and the lowest efficiency is thin-film solar panels.
If it is used for indoor wireless sensors, calculators, etc., you can choose thin-film solar panels. If it is used for outdoor GPS TRACKER, IOT, traffic lighting, etc., you can use PERC or traditional monocrystalline solar panels. If it is used for signal tower, small off-grid power station, you can choose Mono PERC solar panels or polycrystalline solar panels.

With the further improvement of technology, when thin film solar panels, traditional monocrystalline solar panels and polycrystalline solar panels encounter bottlenecks, Mono PERC solar panels will become the choice of most people. As a manufacturer of small solar panels, WSL Solar will provide customers with very constructive suggestions during the product development phase to avoid saving development time and money.

Evolution of Silicon Wafer Size

图片
Silicon wafers are divided into semiconductor wafers and photovoltaic wafers according to their uses. Photovoltaic silicon wafers can be single crystal silicon or polycrystalline silicon, and semiconductor silicon wafers can only be single crystal silicon. The biggest difference between the two is that the content and purity of silicon are different. The conversion efficiency of monocrystalline silicon is generally about 18.5%~25%, and the conversion efficiency of polycrystalline silicon wafer is about 17.3%. Correspondingly, monocrystalline silicon solar cells have higher photoelectric conversion efficiency than polycrystalline silicon solar cells.                                                                                        Over the years, the silicon  wafer size  has experienced a process from small to large. The increase in silicon wafer size and the continuous progress of photovoltaic technology have promoted the cost reduction and efficiency improvement of the entire pho

What's Epoxy Solar Panel?

图片
Epoxy Solar Panel is a kind of solar panel , but the encapsulation method is different. The solar cell is cut into small pieces by using a laser cutter to make the required voltage and current, and then encapsulated. Due to the small size, the encapsulation method such as glass laminated or PET laminated solar panel is generally not used, but the solar cell sheet is covered with epoxy resin and bonded with the PCB circuit board.           6V Solar Panel (Epoxy) for Solar LED lighting Application notes The size of the solar panel can be customized according to the size required by the customer. The working voltage and working current can be customized. Generally, the epoxy solar panel is used to charge the battery of solar charger, solar light, toy and other small solar application electronic products. The working current is measured in the simulated standard light intensity. The standard test conditions are 1000 W/M 2, 25 ° C, and AM 1.5 conditions. The voltage
