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

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.


How much is shipping and how long is delivery?
Our standard shipping charge is $250 for up to 11 panels and it is increased by $25 for every 4 additional panels. In the event, the product is only available on East or West coast custom quote will be sent to you before the order is processed. Normally, we are able to deliver solar panels within 7 business days.
What is the difference between low price panels and top price panels?
With top tier solar panels, you pay for the brand name, proprietary new technology, higher energy output, and better warranty support.
What are the dimensions of the panel?
Please refer to the product datasheet on the product page. We have a datasheet for every product we sell.
How long is the warranty on the panel?
In general, manufacturers provide a 25 year-long performance warranty and a 10 year-long equipment guarantee. Some manufacturers offer 12-15 years of warranty. More information is available in our warranty support section.
Which panels do you recommend for RV, marine?
We recommend Panasonic and Mission Solar panels for smaller systems as their high energy output and excellent craftsmanship guarantee years of service.
Can this panel be used with a 12v system?
Any of our panels can be used for a 12v system with a properly selected inverter and charge controller.
Can I pick up this panel from your fulfillment center to save on shipping?
Yes, we can set up a pick up at a local distributor. Please call to discuss options and stock availability.
How do I connect these panels?
To achieve the best system efficiency, panels should be connected in series to create higher voltage.
How many panels do I need?
This number is determined by your average energy needs. Depending on the type of panels and energy consumption, you might need anywhere from 12 to 45 solar panels. Remember, the more panels you install the more energy you will get.Please use our solar calculator to estimate your energy consumption and plan on building a solar system that will exceed your energy needs by 25%.
Do you offer discounts?
We do offer discounts for orders of over 50 units. Please contact us for details.
How do I build a solar system?
Please use our solar calculator to estimate what equipment you need. Choose your panels, microinverters, inverters, and solar batteries if necessary.Please note that we do not offer solar system design or installation.
How do solar panels compare?
Solar panels differ by power output, voltage, connection type, size, efficiency, and weight. Some solar panels might be sold together with microinverters as a set.
Can I build a solar system by myself as a Do It Yourself project?
Yes, it is possible if you understand what solar equipment you need and how to connect it together. However, please be mindful that handling your own electrical work without having proper experience might cause life-threatening injuries. Please contact a certified electrician if you do not possess appropriate electrical skills.
Can I connect and charge my solar panel battery directly with the solar panel?
We do not recommend using the solar panel without the charge controller. Using solar panels without the charge controller might damage the batteries.
Can I drill holes into the aluminum frame for mounting?
We do not recommend drilling any new holes to the aluminum frame of the panel as it could damage the internal circuit and solar cells. (Also, any modification to the panel will void the warranty). We recommend only using the pre-drilled holes for mounting.
Do solar panels require maintenance? Can I wash my solar panel?
Solar panels generally require very little maintenance. We recommend cleaning the solar panel with water, glass cleaner (Windex) and microfiber cloth.
Will my panel produce power in an overcast condition?
While solar panels require sunlight to generate solar energy, they will still work in cloudy weather. Even on a cloudy day, solar panels will produce energy just not as much.
Will my panels produce power if covered with snow?
Solar panels cannot produce electricity if covered with snow.
What is the best direction for a solar panel to face?
The best direction for a solar panel to face is the South
