Why does solar panel efficiency matter?
Using high efficiency solar panels means more savings on your electricity.
When your installer designs your solar array, one of the questions you might have is: “How many solar panels will I need?”
The answer is determined by a number of factors, including your home’s average electricity usage in a year and how much sun hits your roof.
But, one of the most important factors is the efficiency of the solar panels you choose.
The more efficient they are, the more powerful a solar system will fit on your roof.
The other advantage is that fewer high efficiency solar panels could be needed to provide the electricity you need (this is a big advantage for smaller roofs or roofs that experience some shading).
What is solar panel efficiency anyways?
Let’s break it down.
First off, solar panel efficiency is a measurement.
What does it measure?
How much sunlight a solar panel can convert into usable electricity.
So a solar panel with 20% efficiency will produce more electricity than a solar panel with 15% electricity if they’re provided with the same amount of sunlight.
What factors affect solar panel efficiency?
There are a few factors that determine a solar panel’s efficiency.
- The materials used
- The organization of the wires and components
- Reflection (if the sun bounces off them they have less efficiency)
How efficient are typical solar panels?
Most solar panels are between 14% and 20% efficient.
Announcing the LG NeON® 2 355W
Featuring LG’s Cello Technology, the LG NeON® 2 N5 provides 3% more power output, making them 20.5% efficient!
That might not seem like a huge upgrade, but every percentage makes a difference in how much power your system can output.
For example, if you compared two different panels of the same size, one with 21% efficiency and the other with 14% efficiency, the 21% efficient would produce 50% more kilowatt-hours (kWh) of electricity. That’s pretty significant when it comes to saving money and getting the most out of your solar panel investment.
Runs Cool on Hot Days
One of the questions you may have as a homeowner is how does heat affect solar panel efficiency?
Solar panels are tested at a temperature of about 77 degrees F, so heat can reduce output efficiency by 10-25%!
The exciting news is that the LG NeON® 2 performs well on hot days due to its low temperature coefficient.
Be the envy of your neighbors with the LG NeON® 2 panels that were designed with aesthetics in mind using thinner wires that appear all black at a distance.
LG NeON® 2 has a module performance warranty. At 25 years, the NeON® 2 is guaranteed to produce at least 90.1% of its labeled power output.
The NeON® 2 is covered by a 25-year limited product warranty. In addition, up to $450 of labor costs will be covered in the rare case that a module needs to be repaired or replaced.
