Product Overview

The Solarland USA SLP175S-12 polycrystalline 175 watt solar panel is engineered for reliable off‑grid power where durability matters. Designed around a 36 cell layout, this robust module delivers a maximum power output of 175 Wp at 19.06 V, making it ideal for 12 volt battery based systems. It suits applications such as remote cabins, RVs, marine systems, telecom equipment, lighting and small industrial loads. The panel uses tempered glass and an anodized aluminium frame to protect the cells from harsh outdoor environments.

With a wide operating temperature range from -40 to 85 °C, this module continues performing in both hot and cold climates. A balanced power tolerance of -5 to +5 percent helps ensure predictable output in real‑world conditions. The Solarland SLP175S-12 panel weighs only 12 kg, so handling and mounting are straightforward for installers and DIY users. Long term power production is supported by a gradual total degradation rate of just 0.8 percent per year. This design helps your off‑grid or backup system remain dependable over many years of operation.

Key Benefits

Optimized for 12V off‑grid systems: Nominal 12 volt output works seamlessly with common charge controllers and battery banks, simplifying system design.

Reliable 175W power rating: A maximum power rating of 175 Wp supports small to medium loads, from lighting to pumps and electronics.

Rugged mechanical design: Tempered glass, 35 mm anodized aluminium frame and robust construction help withstand wind, snow and transport stress.

Wide temperature tolerance: Operation between -40 and 85 °C supports dependable performance in deserts, coastal climates and cold regions.

Long term power stability: Low total degradation and defined power warranties help preserve system output over the panel lifetime.

Lightweight and easy to install: At just 12 kg, this solar module is easier to lift, align and secure during rooftop or ground installations.

How It Works

The Solarland SLP175S-12 solar panel converts sunlight into direct current electricity using its 36 polycrystalline cells. When sunlight hits the cells, energy from the light frees electrons inside the semiconductor material, creating an electrical current. This current flows through internal busbars and wiring and exits via the panel’s junction box or attached leads. The module is designed to work as part of a 12 volt system, where it connects to a charge controller, battery bank and DC or AC loads. Performance is influenced by irradiance, cell temperature and mounting orientation, so correct installation maximizes daily energy harvest. Over time, the durable glass and frame protect the cells from weather, allowing consistent power generation throughout the product life.

Photovoltaic energy conversion: The 36 polycrystalline cells are wired in series to reach the required operating voltage. Each cell absorbs sunlight and generates DC power through the photovoltaic effect. Combined, the cells deliver 175 watts at standard test conditions when irradiance and temperature are ideal.

Power delivery to your system: The panel operates around 19.06 V at maximum power, which suits 12 volt battery charging when used with a compatible controller. Current at maximum power reaches 9.18 A, helping batteries recharge steadily during sun hours. Open circuit voltage of 23.25 V and short circuit current of 9.65 A define safe design limits for downstream equipment.

Thermal and environmental management: Cell temperature typically sits around 47 ±2 °C under standard test conditions. A temperature coefficient of power of -0.5 percent per °C means power falls slightly as the panel gets hotter. The glass and frame manage thermal expansion and protect against moisture, so the module continues operating from -40 to 85 °C without structural issues.

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.
