Monocrystalline Cells

Product Overview

The Flagsun Green Power FSM636-180W monocrystalline solar panel delivers reliable 180 Wp output in a compact format, ideal for off grid and small rooftop systems. As a high efficiency 12 V class module, it converts sunlight into clean power with up to 17.9% panel efficiency under standard conditions. This Flagsun FSM636-180W solar panel is designed for users who need dependable performance, simple integration, and long term durability. The module operates safely in challenging environments, with an operating temperature range from -40°C to 85°C. Tempered glass and an anodized aluminium frame protect the monocrystalline cells from impact, moisture, and temperature cycles. The panel supports precise power planning thanks to its 0 to +3% positive power tolerance. Voltage at maximum power is 18.1 V, paired with a strong current of 9.95 A at peak output. Short circuit current reaches 10.53 A, with an open circuit voltage of 22.8 V, making this model suitable for battery charging, PWM and MPPT regulators, and many low voltage applications. With a power range extension from 180 Wp up to 200 Wp within the same series, system designers can scale capacity easily while maintaining a consistent mechanical footprint and look.

Key Benefits

High conversion efficiency: The panel offers up to 17.9% efficiency, allowing more power from limited roof or ground space. This improves overall system yield for residential cabins, mobile setups, and small commercial loads.

Reliable 180 Wp power output: With 180 Wp rated power and a 0 to +3% tolerance, the module consistently delivers or exceeds its nameplate output. This helps installers design arrays with confidence and predictable performance.

Robust thermal performance: The operating temperature range of -40°C to 85°C supports use in hot summers and cold winters. Optimised temperature coefficients limit output losses as cell temperature rises in strong sunshine.

Durable construction materials: A 3.2 mm tempered glass front protects against hail, debris, and handling damage during installation. The anodized aluminium frame adds rigidity and corrosion resistance for long outdoor lifetimes.

Flexible system integration: Electrical parameters suit many 12 V battery banks, charge controllers, and inverters common in off grid systems. The power range from 180 to 200 Wp gives planners options for tailoring system size and cost.

How It Works

The Flagsun Green Power FSM636-180W solar panel converts sunlight into direct current electricity through high grade monocrystalline cells. When light hits the silicon cells, electrons are released and driven by the internal electric field, creating current flow. The module delivers its maximum power at 18.1 V and 9.95 A, where voltage and current are balanced for optimal energy output. At open circuit, the panel reaches 22.8 V with no load connected. Under short circuit conditions, current rises to 10.53 A while voltage drops to near zero. In real applications, a charge controller or inverter keeps operation close to the maximum power point. Temperature affects cell behaviour, so advanced temperature coefficients help forecast performance in hot or cold conditions. Protective tempered glass and the aluminium frame shield the cells while still allowing high light transmission. The result is a compact module that quietly produces clean power wherever it is mounted, whether on rooftops, boats, caravans, or remote sites without grid access.

Monocrystalline energy conversion: Each monocrystalline cell is cut from a single silicon ingot, providing a uniform structure that supports higher efficiencies. Photons from sunlight strike the cell and dislodge electrons, which then flow through the external circuit as usable electrical energy.

Maximum power point operation: The panel performs best near its rated 18.1 V and 9.95 A operating point, where power output peaks at 180 Wp. Charge controllers or inverters with MPPT algorithms track this point during the day, optimising energy harvest despite changing sunlight and temperature levels.

Thermal and environmental management: Cell temperature rises above ambient during strong irradiation, which can reduce power output if unmanaged. The panel’s temperature coefficients for Pmax, Voc, and Isc quantify these changes, enabling accurate system sizing and performance modelling over seasonal conditions.

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.

Brian H

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.
