About product

LG435QAC-A6 is part of the NeON R Series — one of the most recent made by LG. These panels employ cutting-edge technologies to achieve superior efficiency and reliability. 

LG 435 solar panel employs monocrystalline silicon — the most efficient material for converting sunlight into electricity. Each of the model's 66 solar cells consists of a single crystal, unlike cheaper polycrystalline cells that are made of multiple crystals melted together. As a result, not only are monocrystalline panels more efficient, but they are also more resistant to degradation. The efficiency of this model reaches 21.9% — well above the market’s average. 

LG paid as much attention to durability as they did to performance. LG 435 watt solar panel is guaranteed to retain at least 92.5% of output after 25 years. Product warranty for this panel lasts 25 years.

  • 435 W power output
  • 66 full-sized monocrystalline cells
  • 21.9% efficiency
  • 1000 V DC maximum system voltage
  • MC4 connectors
  • 25-year product and 25-year performance warranties

Great productivity through the latest innovations

This LG panel provides 435 W power at 21.9% efficiency. High energy production levels are achieved through the usage of the latest advances in the solar industry, including monocrystalline technology and state-of-the-art antireflective coating. An efficient panel yields more per square foot and pays for itself faster.

Better performance at high temperatures

Excellent temperature coefficient means more energy as temperature rises. Every 1.8°F hike above 77°F will decrease your panel’s efficiency by only 0.29%, according to LG 435 solar panel spec sheet.

Quality and reliability

LG 435W Neon R receives multiple quality checks throughout the manufacturing process and is subject to stringent quality and reliability testing. The manufacturing facilities are highly automated, eliminating the risk of human error. LG is dedicated to quality, safety and reliability to ensure you get the very best.

Low degradation for a longer lifespan

LG Neon R 435W will lose no more than 1.5% of their power output in the first year of service. From the 2nd year to the 25th year, the average annual power decline will be no more than 0.25%. The module retains over 92.5% of its original output after 25 years. Guaranteed by LG.

Certified for the most challenging environmental conditions

LG 435W solar panel is resistant to PID, salt, acid and ammonia. It can also withstand up to 5400 Pa mechanical load on the front and 4000 Pa on the back. Such robustness is mainly due to the 1.57" thick anodized aluminum frame and a layer of protective glass.

A1 store is without a doubt one of the best for solar. They deal with everything quickly and without hiccups, from order processing to pick up. Purchasing equipment from A1 is very easy

These panels offer good value for the money. Although they are somewhat big, we were able to effectively place them on our roof. We have only ten modules, but they offset almost all our electricity costs. Thank you, A1

Although it was difficult to decide, we ultimately went with these 435W panels from LG. The modules are pretty reasonably priced despite the fact that the brand is big and well-known. A1Solar demonstrated once more that they are an excellent partner

Will you offer any discount on these panels due to the warranty risk of LG discontinuing solar panel production?

Hi Howard, They currently go with a 15% discount. As for the warranty, LG says it will honor all warranties despite the cessation of production.
You sell panels with higher efficiency but much cheaper, what am I missing?

There are many important factors aside from efficiency. We will gladly help you if you provide more details.
What does 4000 Pa mean? And why is it even important?

This number shows how resistant to external loads the rear of the panel is. The higher this number, the stronger winds a panel can handle.
A power warranty is great, but how will I know the panel is underperforming?

Virtually all modern inverters have monitoring capabilities, making it much easier to spot any drop in performance.
