Product Overview

The Flagsun Green Power FSM636-190W monocrystalline solar panel delivers reliable 190 W power output for small to medium systems. It is designed for off‑grid, backup, and residential applications that demand stable performance and long service life. High efficiency monocrystalline cells help maximize energy harvest even on limited roof or ground space. The module operates within a wide temperature range from -40 to 85 °C for year round use. A panel efficiency up to 18.9 percent supports excellent power density per square meter. Power tolerance from 0 to plus 3 percent ensures dependable output with reduced performance risk. Tempered glass and an anodized aluminium frame add mechanical strength and weather protection. The FSM636-190W sits in a versatile 180 to 200 W product range, giving system designers flexible matching options. It is manufactured in China by Flagsun Green Power Co., Ltd., a specialist in cost effective solar modules. This robust design makes the panel a practical choice for cabins, RV systems, telecom loads, and small grid tie arrays.

Key Benefits

High efficiency power density: Panel efficiency up to 18.9 percent allows more power from compact mounting areas.

Reliable output tolerance: A 0 to plus 3 percent power tolerance supports consistent field performance over time.

Stable electrical performance: Optimized Vmpp at 18.3 V and Impp at 10.38 A simplify system matching and controller sizing.

Robust mechanical design: 3.2 mm tempered glass and an anodized aluminium frame enhance durability in outdoor conditions.

Wide operating temperature range: The module operates from -40 to 85 °C for reliable service across harsh climates.

Versatile power range options: The 180 to 200 W series supports flexible string design and project optimization.

How It Works

This monocrystalline solar panel converts sunlight directly into usable DC electricity through high purity silicon cells. When sunlight reaches the cell surface, photons transfer energy to electrons in the semiconductor. These energized electrons move through an internal electric field to create current flow. At the array level, panels are wired in series or parallel to reach the desired voltage and current. The FSM636-190W delivers 190 W at standard test conditions, with Vmpp at 18.3 V and Impp at 10.38 A. Its open circuit voltage of 23 V and short circuit current of 10.89 A define system design limits. Temperature coefficients control how power changes under real operating temperatures. The tempered glass and aluminium frame protect the cells while allowing high light transmission. Energy produced by the panel is normally routed to a charge controller, hybrid inverter, or DC load. From there it can be stored in batteries, converted to AC power, or consumed directly on site.

Monocrystalline cell conversion: High purity monocrystalline cells absorb incoming sunlight across the front surface area. An internal junction separates charge carriers and drives electrons into the external circuit. This process yields stable DC output suitable for battery charging and inverters. The 18.9 percent module efficiency helps maximize energy yield under standard conditions.

Voltage and current operating point: The module operates around its maximum power point at 18.3 V and 10.38 A. MPPT charge controllers or inverters track this point to extract maximum available power. Open circuit voltage at 23 V provides headroom for cold conditions and wiring losses. The short circuit current of 10.89 A defines conductor and protection device sizing.

Thermal behavior and reliability: Power output decreases slightly as cell temperature rises above test conditions. The temperature coefficient of Pmax is -0.43 percent per degree Celsius, managing performance loss. Voc changes with a coefficient of -0.34 percent per degree Celsius, affecting cold weather voltage. Isc increases marginally with a 0.049 percent per degree Celsius coefficient, maintaining current stability.

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.

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

Highly Recommend

I would like to take the time to express the outstanding service that I was provided with by Portlandia Electric Supply. They provided me with all the answers to my questions, and after reviewing our quote over the phone I felt comfortable proceeding to order my kit. It’s exactly what I needed and they were there to help us over the phone when we had questions installing it. I highly recommend others in need to choose Portlandia Electric Supply.

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.
