Product Overview

The Sungold SGSP-220W/37.2V SunPower monocrystalline glass solar panel delivers reliable 220W output in a compact footprint. This high-efficiency module is engineered for off-grid cabins, RV systems, marine use, and small residential applications. With advanced SunPower cells and a glass construction, consistent performance is maintained even in demanding conditions. A panel efficiency of 24.4% helps more power be produced from limited roof or mounting space. The panel operates within a wide temperature range from -40°C to 85°C for dependable energy in varied climates. A robust design, IP65/IP67 junction box options, and 1000V system voltage compatibility support flexible system integration. Manufactured by Shenzhen Sungold Solar Co., Ltd. in China, this module offers a practical balance of performance, durability, and long-term value. Its 10-year product warranty and designed 25-year service life make it a strong choice for long-lasting solar installations.

Key Benefits

High power density for limited spaces: The 220W rating and 24.4% cells efficiency allow strong output from a relatively small panel area. This makes the module ideal for RV roofs, boats, and compact off-grid sites.

Premium SunPower monocrystalline cells: SunPower back-contact cells are used to deliver excellent performance and reliability. Energy harvest remains high under real-world conditions with reduced internal losses.

Wide operating temperature range: Operation from -40°C to 85°C supports installations in harsh winter and hot summer environments. Stable performance is supported by a low power temperature coefficient of -0.32%/°C.

Durable, weather-resistant design: A tempered glass surface and robust frame construction are combined with an IP65/IP67 junction box. This design helps protect against moisture, dust, and mechanical stress during long-term outdoor use.

Proven warranty and long service life: A 10-year product warranty is backed by a designed service life of 25 years. System owners gain confidence in long-term output stability and reduced maintenance needs.

How It Works

The Sungold SGSP-220W/37.2V solar panel converts sunlight into usable DC power using high-efficiency SunPower monocrystalline cells. Incident light is absorbed by 60 solar cells arranged in a 6x10 matrix within the glass laminate. Each cell generates an electric current, and the cells are interconnected to build usable voltage and power. The module delivers a maximum power of 220W at a voltage of 37.2V and current of 6.05A under standard test conditions. Power is transferred through the junction box at the rear of the module to external cables, charge controllers, or inverters. In an off-grid system, energy usually charges a battery bank before serving DC loads or an inverter. In grid-tied or hybrid systems, compatible inverters transform DC power into AC electricity for household or commercial use. The panel continues operating within its specified temperature range while its temperature coefficients manage performance changes as conditions vary.

High-efficiency SunPower cell generation: SunPower cells with 24.4% efficiency capture a larger share of incident sunlight. Their back-contact design reduces shading from front busbars and enhances current flow across each cell.

Optimized voltage and current output: At maximum power point, the module delivers 37.2V and 6.05A for a 220W output. The open-circuit voltage of 43.8V and short-circuit current of 6.41A support flexible system design.

Protected power delivery and system integration: A waterproof junction box rated up to IP67 safeguards electrical connections against moisture and dust. Power is then routed to a compatible controller or inverter within systems up to 1000V DC.

Customer Success Stories

Troy P

EG4 off-grid base kit, Happy with my purchase.

This is the first stage of my three planned purches. I got the eg4 inverter 6000 XP base kit with six 400 watt panels and the two server rack batteries. Did a little online research and followed the instructions and it got set up without any issues. Right now I'm just running it in my garage on a single outlet and have been running dual 750 watt water distillers with it. Once I get the second inverter and a bunch more panels and batteries, I plan on attaching it to my subpanel in my house that has my lights and outlets and appliances on it. Then I'll get a soft start for my AC and blower and run it on my main panel.

Jacob B

Easy Process, Genuine Support

Trying to pick the correct solar system for your needs can be very technical and frustrating. I wanted to thank Yvhan and the Portlandia Electric supply team for their patience and helpful attitudes through multiple calls. I feel like we were able to narrow it down to what worked for me and my family. My system works great and I couldn't be happier to have picked Portlandia Electric Supply.

Patrick B

Off Grid Solar Purchase

I wanted to get an offgrid solar system for years but didn’t know where to start. I found Portlandia Electric Supply on Facebook and decided to submit a quote. Within 24 hours I had a custom proposal that was almost half the price of the companies I had previously got quotes from. My wife and I decided to order online and the kit came in a timely manner and it was an easy install. Great company to work with!

James Martin

Solar Kit for Mobile Work Van

As a professional videographer, I needed reliable power on the go.Portlandia Electric Supply Delta Pro and roof-mounted panels were the perfect solution. Setup was easy, and the kit included everything needed. The Delta Pro powers my cameras, lights, laptop, and a small fridge with impressive battery capacity.

Keith S

Best Tech Support

You folks have been wonderful guiding me through the ins and outs of going solar. Plus your tech guys Rod and Nelson are the absolute best. They explained all the different aspects of inverters, batteries and how to keep them in top condition. Too much more to put here… but no other company has the 100% tech support you provide for your customers!

Coll A

Great Experience

My experience with Portlandia Electric Supply has been excellent. Before the sales, they answered all my questions to assure that I got what I needed. After the sales they continued to support me with answers and help. I had a warranty issue with a unit, and it was handled as well as possible. I would recommend them to anyone looking to go solar.
