Mitsubishi solar panels: the complete review

Mitsubishi solar panel review

Mitsubishi Electric is one of the world’s largest manufacturers of electronics and electrical equipment, including televisions, air conditioners, and solar panels. The company was founded in 1921, and it manufactured the first solar panels to provide power to satellites in the 1970s. All of Mitsubishi’s solar panels are manufactured in Japan. Although they are relatively new to the U.S. market, Mitsubishi solar panels are increasingly popular in quotes to solar shoppers comparing their options on the EnergySage Solar Marketplace.

Mitsubishi solar panels: MLE and Diamond Premium series

Mitsubishi Energy offers two series of solar panels for residential systems:

  • MLE Series
  • Diamond Premium Series

EnergySage has reviewed the product specifications of each Mitsubishi Energy panel series to make your solar research process easier. As the leading online marketplace for homeowners considering solar, EnergySage is uniquely positioned to evaluate the technical specifications of Mitsubishi solar panels and help you compare them to other manufacturers on the market.

How Mitsubishi solar panels compare to other panel manufacturers 

There are four key metrics that you should review as you evaluate solar panel quality: efficiency, performance, warranties, and price. EnergySage has developed Mitsubishi solar panel reviews for each metric to help make your solar decision easier. We’ve also created a comparison of Mitsubishi panels against other leading panel manufacturers that are frequently featured in offers to homeowners and businesses shopping for solar on the EnergySage Solar Marketplace.

Efficiency

The term “solar panel efficiency” refers to how well a solar panel captures sunlight and converts it into useful electricity. In the same conditions, a high-efficiency solar panel will produce more electricity than a lower-efficiency panel of the same size. For this reason, a higher efficiency rating is generally preferable.

The efficiency of your Mitsubishi solar panels will vary depending on the specific model that you choose for your system. Panels in Mitsubishi’s product line have an efficiency rating of 16.3% to 16.9%. This puts Mitsubishi panels in the “standard” efficiency category for solar.Mitsubishi solar panel efficiency

 

Performance (Temperature Coefficient)

For this portion of EnergySage’s Mitsubishi solar panel reviews, we use the temperature coefficient to evaluate solar panel performance. The temperature coefficient is an indicator of how well your solar panel can handle less-than-ideal conditions. Solar panels, like other electronic equipment, perform better when they are kept cool (ideally around 25° C/77° F). The temperature coefficient tells you how much your panel’s performance will change during hot sunny summer days.

For every degree above 25° C (77° F), your solar panel’s electricity production will decrease by its temperature coefficient. For example, the Mitsubishi PV-MLE275HD2 panel has a temperature coefficient of -0.44%/°C. This means that, if the panel’s temperature increases by one degree from 25° C (77° F) to 26° C (79° F), its electricity production will decrease by 0.44%. If its temperature increases all the way to 35° C (95° F), electricity production will reduce by 4.4%.

Your solar panels will likely see more than a few hot and sunny days over the course of each year, so ideally, they will have the lowest temperature coefficient possible. As you can see in the graph below, Mitsubishi panels have temperature coefficients ranging from -0.45 to -0.44.Mitsubishi solar panel performance graph

 

Warranties

Whether you’re buying a TV, a car, or solar panels, the manufacturer should stand behind their product with a strong warranty. A solar panel’s materials warranty (sometimes referred to as the product or equipment warranty) is a guarantee from the manufacturer that they will replace your panel if it fails as a result of manufacturing defects or environmental issues.

Most solar panel manufacturers offer a 10-year materials warranty, but some higher-end solar panels come with a 12, 15, 20, or even 25-year warranty. Mitsubishi offers a standard 10-year warranty against any defects in their solar panels.

How much do Mitsubishi panels cost?

For many homeowners, the final decision around the solar equipment you choose rests on cost. The total price you pay for a solar energy system with Mitsubishi panels will vary depending on the other equipment (such as inverters and mounts) used in the installation, as well as the characteristics of your roof.

To identify the range of prices for Mitsubishi PV systems, we analyzed quotes including Mitsubishi solar panels that homeowners received from installers on the EnergySage Solar Marketplace. Most Mitsubishi PV systems are typically priced between $3.18 and $3.71 watt, which makes them a good value in the market for home solar.

Mitsubishi solar panels compared to competitors

 

 

Mitsubishi Solar Panels 25th Percentile 50th Percentile 75th Percentile
Efficiency (%) 16.3-16.9%  15.7% 16.2%  16.8%
Temperature Coefficient (%/°C)  -0.45 to -0.44  -0.45 -0.43 -0.41
Warranty (Years)  10  10 12  25
Price ($/Watt)  $3.18 – $3.71  $3.25  $3.50  $3.75

This means that, for an average 5 kW system, your gross cost (before you subtract any tax credits or other incentives) would be anywhere from $15,900 to $18,550. Additionally, most homeowners end up paying much less than the total gross cost. With the 30 percent federal tax credit for solar, which everyone is eligible for, a 5 kW system with Mitsubishi would cost anywhere from $11,130 to $12,985. There are plenty of state-level solar incentives and rebates that can help you reduce upfront costs even further.

Mitsubishi panels may not offer the best efficiency or performance in the solar industry, but they’re still an appealing choice for shoppers comparing solar quotes on the EnergySage Solar Marketplace. The price of a solar PV system with Mitsubishi panels is in line with the industry average, and the company is a trustworthy brand has been manufacturing electronic equipment for nearly a hundred years.

How to find the best price on Mitsubishi solar panels

The best way to determine whether Mitsubishi solar panels are the best solar panels for your home is to review multiple quotes with different solar equipment options before making a decision. When you compare all of your options on the EnergySage Solar Marketplace, you’ll find the right combination of price and quality that meets your needs.
