Product Overview

The SPOT S-240-60-1 240W polycrystalline solar panel delivers reliable power and solid efficiency for homes and businesses. This robust module uses high quality multicrystalline silicon cells that are electrically matched for stable performance in real world conditions. With a rated power of 240 watts and a module efficiency of 14.75 percent, it is well suited for village power, security lighting, small commercial arrays, and off grid systems. The panel operates at a practical 29.8 volt maximum power voltage, which makes system design easy with modern MPPT charge controllers and inverters. A durable anodized aluminum frame, tempered glass, and EVA encapsulation help protect the cells against moisture and harsh outdoor environments. The SPOT S series has been engineered for both grid tied and stand alone applications, giving installers flexibility across many project types. Manufactured under ISO 9001 quality management and backed by a 25 year limited warranty, this panel offers dependable long term energy production with a competitive cost per watt. It is an excellent choice where proven technology, strong construction, and accessible performance are required.

Key Benefits

Balanced 240W power for many system sizes: The 240 watt rating fits well into both small and medium arrays, so system expansion is straightforward. It can be combined with other modules in the 230 to 250 watt SPOT range while keeping similar electrical characteristics.

Reliable multicrystalline cell technology: Proven polycrystalline silicon cells provide stable performance with efficiencies up to 14.75 percent. Electrical matching between cells minimizes mismatch losses and improves overall module output over time.

Durable construction for outdoor use: Tempered low iron glass, EVA encapsulation, and a high quality backsheet help keep moisture out and protect against UV exposure. The strong anodized aluminum frame resists corrosion and offers multiple mounting points for secure installation.

Compatible with 1000V systems: The 1000 volt maximum system voltage allows long strings on many commercial inverters. Designers can optimize string length to reduce balance of system costs and simplify wiring runs on site.

Long term warranty and certified quality: Compliance with IEC 61215, IEC 61730, and TIS 1843-2553 supports safe operation in professional installations. The 25 year limited warranty and ISO 9001 manufacturing give confidence in long term energy yield.

How It Works

This SPOT 240W module converts sunlight into DC electricity using 60 interconnected polycrystalline silicon cells. When sunlight hits the cells, photons transfer energy to electrons in the semiconductor material and create an electric current. The module operates at a maximum power point around 29.8 volts and 8.06 amps under standard test conditions. A charge controller or grid tied inverter tracks this point to draw optimum power from the panel. Built in bypass diodes inside the junction box help limit power loss when some cells are shaded. The module can be installed in series strings and parallel strings to reach the voltage and current needed by the rest of the solar system. Once DC power leaves the panel, it flows through cabling to a charge controller, battery bank, or inverter, where it is managed and converted into usable AC or stored energy.

Light capture and DC generation: Low iron tempered glass allows more sunlight to reach the 60 multicrystalline cells while shielding them from impact. Each cell produces a small voltage when illuminated, and the cells are wired together to raise the overall module voltage. Under rated conditions the panel reaches 37.1 volts open circuit and 8.62 amps short circuit current.

Maximum power tracking and system integration: The module has a clearly defined voltage and current at maximum power, known as Vmpp and Impp. Modern MPPT charge controllers and inverters constantly adjust their operating point to stay near 29.8 volts and 8.06 amps. This tracking extracts the best possible energy from the panel as sunlight and temperature change through the day.

Protection, wiring, and energy delivery: EVA encapsulant, a composite backsheet, and an anodized aluminum frame secure the laminate and preserve electrical insulation up to 1000 volts. Three bypass diodes in the junction box help current flow around shaded cell strings, reducing hot spots and efficiency losses. A 4 mm² cable pair, each 750 millimeters long, connects the module to the rest of the system, delivering DC power to batteries, loads, or a grid connected inverter.

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!
