Description

Sungold 290W monocrystalline silicon solar panel conversion efficiency up to 22%, have a longer lifespan.

To prevent solar cells from overheating, our solar panels are equipped with high-performance bypass diodes to minimize power drop due to shading.

In our Sungold solar panels, each sub-string consists of 36~40 connected cut cells in a way that ensures that there is no distance between cells.This innovative technique maximizes the space for cell array and significantly improves the panel’sefficiency compared to the conventional method.

Pre-drilled holes on the back of the panel allow for quick installation and fixing, ideal for off-grid applications including RVs, roofs, cabins, yachts, etc.

Product Features

SGD-M2-290W Rigid Solar Panl

Shingled process

Shingle process

The shingle process uses the latest single crystal cell, using a special welding method to connect the cell. The area under the same power output is smaller, the front can be more strongly affected, and it is also one of the latest production processes in the solar industry.

Higher Efficiency

The SGD series 290 watt solar panel uses the latest technology single crystal silicon solar cells, using multi-layer cell technology to make it the highest quality, with a conversion efficiency of up to 22%.

High efficiency
Waterproof

Waterproof

SGD series shingled solar modules is the most mature design. The connection between the glass panel and the aluminum frame is encapsulated with solar silica gel, which will not allow any water vapor to enter. SGD series 290 watt solar panel has IP67 waterproof grade. The whole product will not be affected by rain or water splashing. It can work outdoors for a long time without worrying about any quality problems.

Easy installation

Pre-drilled holes on the back of the solar panel allow rapid mounting and fixing. It is ideal for off-grid applications including RVs, rooftops, cabins, yachts, etc., and suitable for most solar panel fixing brackets on the market.

Easy installation

Specifications

Sungold PERC Shingled-cell solar panels have a rigid aluminium frame and sleek black cells that allow the panels to stand out from others in it’s market. With its unique cell design and durable build, it can be used in a variety of off-grid solar systems.

FAQ

SGD series shingled-cell solar modules are one of the most mature products. The weight of the product is relatively thick, but stable, worse-free use is greatly reducing the customer’s after-sales worries.

Conventional RV roof, roof off the grid system, traffic road peripheral products, etc.

Yes, you can, the USB power comes from the battery, and the controller will protect the battery from overcharging and overloading.

The low voltage disconnect is set in most of chargers / controllers, not on solar panel. My suggestion is not to charge yours battery without controller, you will damage your battery.

The panels are not affected by ice, snow, or rain, but you lose some efficiency in bad weather.

Sungold solar is one of the leading manufacturers of solar panels in China. Sungold solar focuses on manufacturing solar panels and keeps innovating processes.

The products use specially developed patented materials and the latest solar cell technology to achieve higher conversion efficiency. According to the different needs of customers, we also provide customized services.

1.Question:What are the advantages of SGD series fixed solar panels?

Answer: SGD series fixed solar panels are one of the most mature products. Although the weight of the product is relatively thick, stable and trouble-free use is greatly reducing the customer’s after-sales worries.

2.Question:Which places are best equipped with Sungold SGD series fixed solar panels products?

Answer:  Conventional RV roof, roof off grid system, traffic road peripheral products, field fixed use, etc.

3.Question:Can i leave a usb battery pack (type c output) plugged in to the usb solar controller port for long periods, so it will constantly charge safely?

Answer: Yes, the USB power comes from the battery and the controller will protect the battery from overcharging and overdischarging.

4.Question:How to set low-voltage disconnect?

Answer: The low voltage disconnect is set in most of chargers / controllers, not on solar panel. My suggestion is not to charge yours battery without controller, you will damage your battery.

5.Question:I have solar generators with built in charge controllers. Can this solar panel be plugged directly into my solar generator cable?

Answer: I don’t think so. You need a MC4 adapter to fit your generator.

6.Question:Will these panels work in partial shade?

Answer: Yes. It reduces output dramatically as in all solar panels.
