Solaria is one of the rising stars of the solar panel industry. The company was established in the early 2000s and produces its high-efficiency all-black solar panels in the United States and South Korea. Thanks to their reasonable price tag, high efficiency and strong warranties, Solaria solar panels are gaining popularity shoppers comparing solar quotes on the EnergySage Solar Marketplace.
EnergySage has reviewed the product specifications of each Solaria solar 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 Solaria solar panels and help you compare them to other manufacturers on the market.
How Solaria PowerXT 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 Solaria panel reviews for each metric to help make your solar decision easier.
Based on EnergySage’s analysis, Solaria’s PowerXT solar panels are a good investment for homeowners and businesses seeking high-quality panels for their solar installation. They’ve earned EnergySage’s “Premium” rating, a distinction given to less than ten percent of solar panels currently available on the market. Their North American manufacturing presence also makes them a good option for solar shoppers who want to support American businesses.
Take a look at how Solaria solar panels compare against other leading panel manufacturers that are frequently featured in offers to homeowners and businesses shopping for solar on the EnergySage Solar Marketplace. You can learn more about each of these criteria in the breakdown below.
Solaria panels compared to competitors
|Solaria Panels||25th Percentile||50th Percentile||75th Percentile|
|Efficiency (%)||18.7% – 19.3%||15.7%||16.2%||16.8%|
|Temperature Coefficient/Performance (%/°C)||-0.4||-0.45||-0.43||-0.41|
|Price ($/Watt)||$2.98 – $3.30||$2.95||$3.17||$3.40|
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 Solaria panels will vary depending on the specific model that you choose for your system. Panels in Solaria’s product line have an efficiency rating of 18.7% to 19.3%, which places them in EnergySage’s “Premium” category for solar panel efficiency. Only five percent of solar panels meet the criteria for a Premium rating.
Performance (Temperature Coefficient)
For this portion of EnergySage’s Solaria PowerXT 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 Solaria 330R-WX panel has a temperature coefficient of -0.40%/°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 0.4%. If its temperature increases all the way to 35° C (95° F), electricity production will reduce by 4.0%.
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, all Solaria solar panels have a temperature coefficient rating of -0.40.
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. Solaria offers a remarkable 25-year warranty against any defects in their solar panels – one of just four brands in EnergySage’s comprehensive solar panel database to do so, and another reason that Solaria earns a Premium panel rating.
How much do Solaria 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 Solaria 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 Solaria PV systems, we analyzed quotes including Solaria solar panels that homeowners received from installers on the EnergySage Solar Marketplace. Most Solaria PV systems are typically priced between $2.98 and $3.30 per watt, which puts them in the middle range of solar panels intended for small-scale use.
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 $14,900 to $16,500. 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 Solaria panels would cost anywhere from $10,430 to $11,550. There are plenty of state-level solar incentives and rebates that can help you reduce upfront costs even further.
How to find the best price on Solaria solar panels
The best way to determine whether Solaria offers 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.
