Product Overview

The KL Solar KL250 250W polycrystalline solar panel is designed to deliver reliable power for residential, commercial, and off‑grid applications. This robust 60‑cell module offers a rated maximum power output of 250 Wp, making it a dependable choice for users who want stable performance at an attractive price point. The panel operates at a maximum power voltage of 29.94 V and a maximum power current of 8.35 A, allowing it to integrate smoothly with a wide range of inverters and balance of system components. With a maximum system voltage rating of 1000 V, the KL250 is suitable for array configurations in both grid‑tied and stand‑alone systems. The module uses proven polycrystalline silicon cells laminated under toughened low‑iron PV glass for improved light transmission and durability. An anodized aluminium frame provides mechanical strength while keeping the overall weight at 23.5 kg for easier handling during installation. Manufactured by KL Solar Company Pvt. Ltd in India, this panel is well suited for utility grid‑supplemental systems, telecommunications sites, remote villages, water pumping solutions, and general DC or AC loads when paired with an appropriate inverter.

Key Benefits

Proven 250 Wp output for versatile applications: A maximum power rating of 250 Wp supports a wide range of system sizes and load profiles in homes, businesses, and remote sites. Stable DC output enables efficient operation with inverter‑equipped AC systems and direct DC loads.

Reliable polycrystalline cell technology: The module uses 60 polycrystalline silicon cells in series, delivering consistent performance under real‑world conditions. This technology offers an excellent balance between cost, efficiency, and long‑term reliability for everyday solar projects.

Robust construction for long service life: Each KL250 panel is built with toughened low‑iron PV glass, EVA encapsulation, and a durable back sheet to protect cells from moisture and mechanical stress. The anodized aluminium frame provides structural stability and allows fast mounting on standard array structures.

High system design flexibility: With a maximum system voltage of 1000 V, the KL250 can be wired into larger strings for higher‑voltage arrays. This flexibility supports efficient cabling layouts, optimises inverter input utilisation, and helps reduce balance‑of‑system costs.

Quality‑controlled production and performance testing: Each module is flash‑tested under standard test conditions to confirm power output and electrical characteristics. Manufacturing is carried out using optimised lamination processes to ensure stable encapsulation and long‑term performance in demanding environments.

How It Works

The KL Solar KL250 solar panel converts sunlight into usable electrical energy through its 60 interconnected polycrystalline silicon cells. When sunlight hits the cells, photons transfer energy to the semiconductor material and free charge carriers, creating a direct current flow. This current is collected by the panel’s bus bars and conducted through the junction box to the DC cables. In many systems, the panel’s DC output is routed to a solar inverter, where it is converted into alternating current for household or commercial loads. The module can also feed charge controllers in off‑grid systems for battery charging and DC applications. Built‑in bypass diodes help maintain power delivery in partial shading, while the 1000 V system voltage rating supports efficient string design. Under standard test conditions, the KL250 delivers a maximum power of 250 Wp at 29.94 V and 8.35 A, enabling dependable performance when configured correctly within the overall solar power system.

Solar energy capture and DC generation: The panel’s 60 polycrystalline cells absorb incoming sunlight and convert it into direct current electricity. Electron flow is established across the cell junctions, and the combined series connection raises the operating voltage to an efficient level for system integration.

Power conditioning and system integration: The DC output from the KL250 panel is typically routed to a solar inverter or charge controller, depending on the application. In grid‑connected systems, the inverter synchronises and feeds AC power to the utility network or on‑site loads, while in off‑grid setups the controller manages charging of battery banks and connected DC equipment.

Protection, reliability, and long‑term operation: Bypass diodes within the junction box help protect the module against hot‑spot formation under partial shading. The laminated glass‑EVA‑backsheet stack shields the cells from environmental stress, and the anodized aluminium frame supports secure mounting, ensuring consistent operation over many years of service.

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

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!
