Hyundai Heavy Industries (HHI) is a solar panel manufacturer based in South Korea. Their renewable energy branch began in 2004 and it is now a separate company called Hyundai Green Energy. Since its inception, Hyundai has become a global supplier of solar panels, selling in Europe, the United States, and throughout Asia. 

Hyundai tests their products in UL and VDE-accredited labs and they build their solar panels to be salt mist corrosion-resistant, durable, and high-performing. 

We will review what makes Hyundai solar modules high quality, evaluate their performance and efficiency, and help you determine if they are the right fit to power your home.

    What types of solar panel models does Hyundai offer?

    Hyundai is pretty elusive online, their website is not very helpful so finding information about solar panel specifics is challenging. Because of that, you can check out the reviews from Hyundai solar customers here on SolarReviews. 

    The most well-known models for residential solar applications are the RG Series, RI Series, and the HG Series.

    Your solar panel installer can help you choose which Hyundai model makes sense for your energy needs, but here are a few examples so you can get a sense of what Hyundai offers.  

    Hyundai RG Series

    Hyundai Heavy Industries HiS-S300RG(BK) 300W solar panel

    The Hyundai RG Series is a high-quality, monocrystalline panel, like the HiS-S300RG(BK) 300W (shown above), which is 300 watts and has an efficiency rating of 18.3%. 

    Hyundai RI Series

    Hyundai HiS-S360RI 360W solar panel

    The Hyundai RI Series solar panel offers better performance than the RG series. For example, the slightly more efficient (and sleeker) monocrystalline Hyundai HiS-S360RI 360W features an all-black back sheet and boasts an 18.4% efficiency rating.

    Hyundai HG Series

    The HG Series is fairly standard in terms of efficiency and wattage. Pictured above is the 120-solar cell model, the HIA-S300HG, which features 300 watts and an 18.1% efficiency rating. 

    Hyundai solar panel cost and warranty

    Hyundai solar panels range in cost from $2.48-$3.56 per watt, depending on the panel model, installation costs, and available local incentives. The average cost per watt for solar panels in the United States is currently $3.00, putting the price of Hyundai solar panels in a slightly higher range than average.

    When you work with a local installer, they will help you get the best price on Hyundai solar panels through helping find local rebates and incentives that your home solar system can qualify for.

    Warranties help to make sure you are covered in case your solar panels fail or break. Most high-end solar panel companies offer a 25-year warranty for product quality and power output. 

    Unlike the industry standard, Hyundai offers a shorter timeline with a 10-year product warranty. In addition to the 10-year product warranty, they have a 25-year power output warranty for the RG Series, the RI Series, and the HG Series

    While a power output warranty is important, a product warranty is what covers you if your solar panel breaks. The power output warranty only ensures that your panel will produce a certain amount of power during its lifetime. 

    Based on Hyundai’s short product warranty, it could make sense to spend more on a higher-end solar panel brand like LG, which offers a 25-year product warranty.

    Hyundai solar panel performance

    The best way to determine if one solar panel brand is better than another is to compare metrics like its efficiency and temperature coefficient.


    Solar panel efficiency is the percentage of energy that the solar panels can absorb from the sun and turn into usable electricity. The industry average is between 15%-20%, meaning 15%-20% of the sun’s energy is converted to electricity. 

    Hyundai solar panels have an efficiency rating ranging from about 18%-19%, so any one you choose is sure to have a high efficiency

    What sets Hyundai apart is that their solar panels are built to avoid light-induced degradation and potential induced degradation (PID). Essentially, this means that Hyundai solar panels account for potential ways that solar panels can lose unnecessary energy. This way, your panels remain at peak performance throughout their lifetime. 

    Temperature coefficient

    The performance of solar panels is an important factor - well-performing panels are key to paying less in electric bills. Knowing the temperature coefficient of your solar panels is helpful in understanding performance. 

    The temperature coefficient is measured by how much the performance of the panels decreases by each increasing degree in temperature.

    However, this is generally not a big concern because solar panels are made to withstand extreme heat and weather conditions. Solar panels are tested and meant to handle 25 degrees celsius, or 77 degrees Fahrenheit. Most solar panels have a temperature coefficient between .3% and .5%, so for each increase in temperature above 25 degrees celsius, the performance decreases by between .3% and .5%.

    Hyundai solar panels have a temperature coefficient of .41%-.45% which puts them right in the middle of the appropriate range. This means, with Hyundai solar panels, you don't have to worry about decreased performance on hot days. 

    Are Hyundai panels right for you?

    Hyundai solar panels are a solid choice for residential solar energy systems. The cost for Hyundai solar panels depends on which model you buy, local rebates or incentives, and the cost of installations in your area. 

    Although Hyundai solar panels are competitive in terms of their efficiency and their temperature coefficient, the warranty offered is not great. This could cost you down the line if you need to pay to replace panels that break after their short warranty is up.

    Your solar installer can help you decide if they make the most sense for your home based on cost, your energy needs, your location, roof pitch, and more.
