Product Overview

The Sail Solar SAS400M-108H 400W monocrystalline solar panel delivers reliable performance for residential and commercial arrays. This high efficiency module is part of the 395–420W Hi Pro 4 family from Sail Solar Energy Co., Ltd in China. The panel provides up to 400W output under standard test conditions with a module efficiency of 20.48 percent. A power tolerance of 0 to +1 percent helps ensure consistent real world yield over its lifetime. The 108 half cell layout uses 182 mm monocrystalline cells to balance high power density with improved thermal behavior. Its compact footprint of 1722 by 1134 mm suits rooftop, ground mount, and small commercial installations. The robust anodized aluminum frame, 3.2 mm tempered glass, and IP68 junction box support long term outdoor durability. With a 1500V system voltage rating and 25A series fuse rating, this panel integrates easily into modern string inverter designs. The SAS400M-108H is designed to deliver stable output even at higher cell temperatures around 45 degrees Celsius NOCT. It offers an attractive option where dependable energy production and efficient use of roof space are priorities.

Key Benefits

High power density in a compact footprint: Up to 400W output and 20.48 percent module efficiency help maximize energy from limited roof space. The 108 half cell layout supports dense array designs without oversizing mounting structures.

Reliable performance across the 395–420W range: The SAS400M-108H sits in a product range spanning 395 to 420W power classes. This consistency makes system design flexible while keeping electrical characteristics closely aligned.

Stable output at real operating temperatures: A nominal operating cell temperature of 45 ±2 degrees Celsius supports reliable production in warm climates. Low temperature coefficients help reduce performance losses as cells heat under strong sun.

Durable construction for long service life: The panel uses 3.2 mm coated tempered glass and an anodized aluminum alloy frame. An IP68 junction box with three diodes and robust MC4 compatible connectors helps protect the module in harsh outdoor conditions.

Flexible system integration: A maximum system voltage of 1500V and 25A series fuse rating suit modern high voltage strings. The 4 mm², 300 mm output cables support straightforward connection to inverters and combiner boxes.

How It Works

This Sail Solar SAS400M-108H monocrystalline module converts sunlight into usable DC electricity through high efficiency silicon cells. The panel uses 108 half cut cells arranged in a 2 by 54 layout to manage current more efficiently. When the panel is exposed to sunlight, photons strike the silicon cells and release electrons. These electrons flow through the cell circuits and generate a direct current output at the module terminals. At standard test conditions, the panel delivers 400W at a voltage around 31.02 volts and a current of 12.9 amperes. Under typical outdoor operation near its NOCT value, the panel produces about 302W at 29.26 volts and 10.32 amperes. By connecting several panels in series and parallel, the array output is matched to a compatible inverter. The inverter then converts the DC energy into AC power suitable for building loads or grid export. Protective features like bypass diodes and robust insulation help keep operation stable and safe over many years.

Monocrystalline half cell energy generation: Each 182 mm monocrystalline cell is cut into two halves to reduce internal resistive losses. The half cell design lowers the current per cell string, which improves efficiency and reduces heat buildup under strong irradiance.

Power output at STC and NOCT conditions: At STC, the module reaches 400W with a Vmpp of 31.02V and Impp of 12.9A. Under NOCT, typical operating power is around 302W with slightly lower voltage and current, reflecting real outdoor performance.

Thermal and electrical protection: Temperature coefficients define how output changes as cells warm or cool. The panel uses three diodes in the IP68 junction box to limit hot spots and protect shaded cell strings, supporting long term reliability for the array.

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.

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!
