Sungold Semi Flexible Solar Panel For Marine SP-90W

Sungold Semi Flexible Solar Panel For Marine SP-90W

The Sungold SP-90w semi flexible solar panel features back-contact SunPower solar cells with efficiencies as high as 24.4%. The semi flexible solar panel has light-shielding properties because each cell operates independently.

It use ETFE materials imported from Japan, the semi-flexible solar panel can withstand high temperatures of 242℃, and the light transmittance is over 95%. This means more power or shorter charging times, besides, it has excellent water resistance.

The SP-90w semi flexible solar panelhas a wide range of applications: when camping, hiking, or hunting, it can be paired with a solar-compatible battery to power a portable power station.

It can be used to power a solar-compatible RV directly, or paired with a solar battery on a boat.Unique frameless design and four metal-reinforced mounting holes (optional) for easy installation

Description

The SP-90w semi flexible solar panel is Sungold’s breakthrough in lightweight solar module for marginal applications. They are lightweight and easy to install, especially on sailboats and campers.

The SP-90w semi flexible solar panel Features SunPower’s world-class back-contact solar cells that deliver up to 24.4% efficiency. It means more power from fewer panels, these solar panels are great space-saving marine solar panels.

Product Features

SP-90W SEMI Flexible Solar panel

90W Excellent low light effect

Good low-light performance and high efficiency

Excellent low light performance with 0.04% power generation gain throughout the year. The solar panel high efficiency is about 25%,which means higher power generation than standard silicon panels of the same area.

Back contact solar cells

SunPower GEN3 solar cells are the only solar cells built on copper. This makes these back-contact cells resistant to cracking and corrosion when bent or exposed to moisture, unlike traditional cells that can fail or lose power.
The substrate is made of advanced lightweight polymer material designed to withstand high UV exposure.The sunpower cell solar panels are different from traditional panels and they are more efficient.

90W ETFE surface
90W Thin, light and semi-flexible

Thin, light, flexible

The marine solar panel is lighter at 4.8lb and thinner at 3mm while being able to bend 30 degrees. The best flexible solar panels means it can follow contours to help you maximise space on boat.

Specifications

Sungold SP-90W semi flexible solar panel uses back contact SunPower solar cell, with efficiency from 22.4% to 24%. Japan-imported ETFE materials allow the solar panels to resist high temperatures at 242℃, and their transmittance is over 95%. Moreover, it features excellent waterproof performance.

FAQ

Flexible solar panels are primarily used to charge solar-compatible batteries and can be used to power equipment and small appliances in off-grid situations such as camping, hunting, movie production, and power outages.

Many new RVs, campers, and travel trailers have solar receptacles that can power auxiliary batteries. You need to make sure the cables have MC4 connectors to be compatible with our flexible solar panels. If not, then you will need to buy an adapter.

Additionally, many DIY hobbyists or organizations modify 12V batteries, such as car batteries, for solar-compatible charging to power vehicles or other types of large devices. This may require purchasing additional equipment, including a charge controller that regulates battery and device voltages.

No, we do not recommend it. Periodic walking of flexible components can cause cells to crack, and while the cells remain electrically connected, cracks can still cause power losses beyond SP Solar Technologies’ control. Also, walking on the panel will void the warranty.

If you look into Flex solar panels, you’ll find that they have a much shorter lifespan than traditional rigid panels. 3-5 years seems to be typical. Delamination of the top protective surface has been one of the main contributors to panel failure. Over the past 4-5 years, many Flex panel manufacturers have changed to a new top coat called ETFE to improve durability. Early signs are improved longevity. Sungold also ensures the stability of the product by changing the ETFE coating. Ultimately proves to be the gold standard in flexible solar panels when it comes to aftermarket, so you don’t have to worry

The reason may be that the battery is cracked, resulting in no voltage output.

Sungold solar was established in 2008, and is a professional chinese wholesale solar panel supplier.

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.
