What is Hyundai Energy Solutions?

Hyundai Energy Solutions began operations in 2016 as a spinoff of its parent company Hyundai Heavy Industries.1 The Korean renewable energy company specializes in producing world-class photovoltaic (PV) equipment including cells, modules, energy storage devices like solar batteries and inverters.

This company is a titan. With an international reach and over $419 billion in total sales, Hyundai will continue to be a name heard commonly throughout the clean energy transition.2 Its solar power products can be found from rooftops in Kansas to the Hyundai Motors test center in Buk-gu, Korea.

Hyundai Energy Solutions might be best known for its work on utility-scale and commercial solar energy installations, but its residential products for both grid-tied and off-grid purposes live up to the same standard. In fact, its residential products compete with some of the solar industry’s biggest names like Tesla, Trina Solar, Qcells and Panasonic.

So how can you tell if Hyundai’s solar PV products are right for you? Let’s find out.

What Products Does Hyundai Energy Solutions Offer?

Hyundai offers a variety of solar products, but for the purposes of this article we’ll be sticking to its residential solar panels. Check out this quick video for an introduction to Hyundai’s products.

Hyundai VG Series

As of June 2022, Hyundai Energy Solutions only offers one type of monocrystalline residential solar module —the VG Series — but it’s available at four different tiers of power and efficiency.

The company’s residential monocrystalline modules are high-quality, employing PERC (passivated emitter and rear contact) shingled technology to provide the high efficiency levels so crucial to residential installations. These high levels maximize the limited space associated with rooftop solar installations, as well as prioritize performance in low irradiation conditions (in other words, shade).

Hyundai’s panels have high power outputs (between 385 W and 400 W — above the industry average), are durable, corrosion-resistant and come with a comprehensive warranty. But more on that later.

Below we’ve compared characteristics of the four VG series models.

Hyundai Solar Panel Efficiency

When it comes to residential solar system installations, efficiency is the name of the game. While power can be restricted by panel size, efficiency is what really sets the best solar panels apart from the pack.

On average, solar panel efficiency ranges between 15% and 20%, meaning that the panel successfully converts that percentage of sunlight into electricity.

Hyundai’s residential VG series boasts efficiency levels averaging right at 20% — a very strong figure for the clean energy company.

It reaches this level through its design that avoids light-induced degradation and potential induced degradation (PID). In simple terms, Hyundai’s panels are more advanced than the average panel when it comes to eliminating unnecessary energy loss.

Hyundai Solar Panel Power Rating

A solar panel’s power rating is perhaps the easiest performance criteria to understand — how much raw power is a module capable of producing at one time? The larger the power rating, the greater the capacity of your solar array.

The sizes of solar arrays are measured by the total capacity. For example, a 6 kW (kilowatt) system would be comprised of 20 300 W (watt) panels (300 x 20 = 6,000 W).

The industry average for power is 300-400 W. The very best residential solar panels on the market are just starting to reach levels over 400 W.

Hyundai’s solar modules have power ratings ranging from 385 W to 400 W — more than enough power to get the job done.

Hyundai Solar Panel Temperature Coefficient

Solar panels are intentionally placed in locations exposed to the elements. The more exposure to direct sunlight, the better. This can create issues in extreme heat conditions, as any electrical equipment’s performance will suffer if it overheats.

This is where temperature coefficient comes into play. Essentially, it measures the amount that a solar panel’s performance suffers in extreme temperatures. Panels with better performance will have smaller temperature coefficients (meaning less change in performance with temperature increase).

Hyundai’s VG series has a temperature coefficient of -0.34%/C. This is a strong figure given that the average temperature coefficient of modern solar modules ranges between -0.3%/C and -0.5%/C.

Hyundai Solar Panel Warranty

A lot of our readers assume that any warranties come from solar installation companies, but that’s not the case. Although warranties from your installer are an important aspect of your panel installation, the warranty that comes from the solar panel manufacturer is just as important if not more so.

Quality solar panels will carry product warranties of at least 10 years, while the very best will also come with 25-year performance warranties (also referred to as output protection guarantees). Here’s what Hyundai’s warranty looks like, straight from the datasheet:

The performance warranty of your solar panels may be the most important consideration. With a linear warranty, you’re protected from solar panels diminishing in power and output, as electronics tend to do, over the course of several decades.

Hyundai guarantees with this warranty that your solar panels will still produce at least 84.8% of their original output by their 25th year of life.

How Much Do Hyundai Solar Panels Cost?

The price of solar panels can fluctuate so much across countries, states and even installation companies due to transportation costs and rebates available in various regions. For this reason, it’s hard to estimate the exact cost of Hyundai’s solar panels.

However, Hyundai’s solar panels are known for being very cost-effective given their above- average power and efficiency. We’d expect Hyundai to land in the medium price bracket for the average reader — equating to $20,000-$25,000 for an average-sized installation after the solar tax credit. For panels as efficient and powerful as the VG series, that’s a great deal.

Hyundai Solar Panels Pros & Cons

Every solar panel manufacturer has its pros and cons. Evaluating them can make it easier for you to figure out which brand is best for your energy goals.

Hyundai Solar Pros

  • Power and efficiency among the best in the industry
  • Excellent value for the price
  • Stellar reputation

Hyundai Solar Cons

  • Slightly limited options
  • Limited warranty coverage

Are Hyundai Solar Panels Worth it in 2023?

Hyundai’s solar panels provide just about everything a homeowner could need — high power, great efficiency, durability and aesthetics — without having to pay more than the industry average.

There aren’t many downsides to choosing Hyundai. One is that the industry leading solar panel manufacturers offer a 25-year product warranty, while Hyundai’s VG series only offers product warranties of 15 years.

A second would only apply to our readers in the United States — by choosing Hyundai you miss out on the opportunity to support the U.S. economy and businesses.

That being said, Hyundai’s PV modules are a solid purchase for any home or business owner looking to support global clean energy efforts.
