Sungold 180w Ultralight Solar Panel SG-PA621-180W
Sungold SG-PA621-180W is a Ultralight Solar Panel 180W with a glass-free design and high-efficiency monocrystalline silicon cells. Weighing just 5.42 kg, it offers excellent resistance to high temperatures and impact. With a short circuit current of 8.62A and a maximum power current of 9.04A, it ensures reliable performance. Featuring an IP67 waterproof rating, CE and ROHS certifications, and a 10-year warranty with 20 years of service life, it’s the perfect solution for outdoor energy needs.
Lighter, Yet More Durable
The 100W solar panel uses advanced fiber-reinforced composite materials and polymer laminates instead of glass, cutting weight while enhancing durability and strength for long-lasting performance.
Strong Structural Design
Achieving flexural strength ≥20MPa, this panel’s multilayer design ensures greater structural integrity, providing robust performance even in harsh conditions compared to traditional lightweight panels.
Optimized Heat Insulation
The backsheet’s low thermal conductivity of 0.2W/(m·K) significantly reduces heat transfer, helping to minimize power loss in high temperatures and ensuring more efficient energy production.
Recyclable and Sustainable Materials
Constructed with fully recyclable, PFAS-free materials, this panel is RoHS-compliant, making it a sustainable choice for eco-conscious clean energy solutions.
HOW TO INSTALL
Glass-free design 180w lightweight solar panel weighs only 11.95 lbs, which is 3/4 of the weight of glass laminated solar panels. with high strength design and impact resistance, it can prevent deformation caused by high temperature or load, and can defend against hail.
Sungold PA621 180W lightweight solar panel utilizes high-efficiency A-grade crystalline silicon cells with a conversion efficiency of up to 22.7% for higher power generation.
Sungold’s cell-level shadow management technology ensures power generation even in shaded areas, eliminating hot spots and maximizing energy output. 120w lightweight solar panels are available in a range of sizes to suit all types of applications. 120w lightweight solar panels can maintain long-lasting high efficiency output and longer service life.
Rugged and Durable
The surface material, HPC, improves the durability of the solar panels while reducing weight through the use of a fiber-reinforced polymer backsheet and weather-resistant front panel. Provides additional resistance to occultation and fracture.
Applications
RV
Balcony
Garden
A 180W solar panel can run small appliances like LED lights, laptops, fans, and small refrigerators. It’s ideal for off-grid systems such as RV, camping, and outdoor applications.
A 180W solar panel typically produces 15 amps in a 12V system (180W ÷ 12V = 15A). In a 24V system, it would produce around 7.5 amps.
The Sungold 621 series solar panels are ideal for RVs, balconies, camping, and garden setups. They are perfect for off-grid power solutions and urban living spaces.
fixed installation, bracket support installation.
Lightweight solar panels are typically made with reinforced composite materials to reduce weight, while flexible solar panels use thin-film technology, allowing them to bend and conform to curved surfaces. Both are designed for ease of installation but differ in material and flexibility.
To run an RV, you typically need 2-4 panels (depending on the panel wattage and your energy consumption). For example, 2 x 180W panels can provide sufficient power for lights, small appliances, and charging devices.
effective option if you plan to wholesale in bulk.
Yes, solar panels are worth it on an RV for off-grid energy. They provide free power from the sun, help reduce reliance on generators, and allow for extended travel without worrying about power supply.
Yes, you can plug a solar panel directly into your RV, but you’ll need a solar charge controller to regulate the charging of your RV’s battery system. Some RVs may come pre-wired for solar panel integration.
Yes, you can install solar panels on a balcony, provided there is sufficient sunlight exposure. Lightweight and compact solar panels are especially suitable for urban spaces like balconies where space is limited.
