How Panasonic HIT 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 Panasonic reviews for each metric to help make your solar decision easier. We’ve also created a comparison of Panasonic solar panels against other leading panel manufacturers that are frequently featured in offers to homeowners and businesses shopping for solar on the EnergySage Solar Marketplace.
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 Panasonic solar panels will vary depending on the specific model that you choose for your system. While the majority of solar panels fall in the 14% to 18% range, Panasonic panel efficiency can range anywhere from 19.1% to 20.3%.
Performance of Panasonic HIT panels (Temperature Coefficient)
For this portion of EnergySage’s Panasonic 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, Panasonic’s VBHN330SA17 panel has a temperature coefficient of -0.258%/°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 0.26%. If its temperature increases all the way to 35° C (95° F), electricity production will reduce by 2.6%.
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. Panasonic’s solar panels offer some of the lowest temperature coefficients in the industry at -0.26.
Panasonic’s HIT™ technology is what gives their products high solar panel efficiency and low temperature coefficient, both of which result in higher electricity production. While conventional solar panels use a single layer of monocrystalline or polycrystalline silicon, HIT™ panels use a combination of monocrystalline and ultra-thin amorphous silicon layers to reduce power loss. The surface of Panasonic’s panels also has a pyramid structure that can reduce reflection and direct more sunlight into the solar cells, which also maximizes electricity output.
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, or even 25-year warranty. Panasonic offers a 25-year warranty against any defects in their solar panels.
Panasonic Solar Panels Price
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 Panasonic 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 Panasonic systems, we analyzed quotes from installers on the EnergySage Solar Marketplace that included Panasonic solar panels. Most Panasonic systems are typically priced between $2.59 and $3.37 per watt – comfortably in the mid-range for solar.
This means that, for an average 6 kW system, your gross cost (before you subtract any tax credits or other incentives) would be anywhere from $15,540 to $20,220. Additionally, most homeowners end up paying much less than the total gross cost. There are plenty of solar incentives and rebates to help you reduce upfront costs, including the 26 percent federal tax credit for solar.
Panasonic solar panels are some of the most competitively priced panels offered to solar shoppers on the EnergySage Solar Marketplace. They offer some of the highest efficiency products on the market for a very competitive price, especially when compared to other high-efficiency products like SunPower.

TIPS FOR BUYING YOUR SOLAR POWER SYSTEM.
Buying a home solar power system can be a very exciting experience, but don’t get too carried away by advertising. Be sure to focus on the important aspects of your purchase as it’s a substantial investment and one you’ll be living with for a long time. The following are some buying solar tips on what to look for when purchasing a system.
Ask friends, family neighbours or colleagues who have had solar PV systems installed. Often the best buying solar tips com from right in your neighbourhood. They’ll be able to tell you about their experiences and perhaps alert you to any problems they experienced. Problems that you’ll be able to avoid. Learn more about potential issues in our consumers guide to solar power – avoiding tricks and traps.
Length of manufacturer’s warranty
Take note of what guarantees the manufacturer offers. If the manufacturer is reputable and the warranty period on the panels is substantial (at least 25 years) you would naturally expect your solar system to last long for a long time, long enough to pay for itself and make you a profit. However, for a warranty to be honoured, the manufacturer needs to be still operating. So, be cautious of brands without a track record in Australia.
Have realistic price expectations
If you are paying substantially less than many other similar size systems quoted, you may find poor quality equipment and/or poor installation work. Quality equipment and installation isn’t cheap and, like all other purchases, you often get what you pay for.
Compare components and warranty periods and check into the company providing the installation. While large, well established companies can pass on substantial savings due to increased buying power, other companies often reduce costs by cutting important corners.
Solar panel certifications
This applies to all solar panel purchases, but especially to the purchases that could attract a government rebate. The certification on solar panels indicates the type of testing that they have undergone. For instance, TUV IEC 61215 confirms that the solar panels have gone through testing by an independent laboratory and have met their advertised specifications. Other certification types are often self-assessed. Therefore, they rely on the company being honest in what it claims.
Decide on the type of panels
It used to be the case that if you had limited roof space you would need highly efficient (and very expensive) mono-crystalline solar panels. This is rapidly changing with advances in polycrystalline panel technology and some thin film technologies. Still, even if you have ample roof space you may still want to consider panel sizes vs. output. Filling up your roof with inefficient panels will affect your ability to add more panels at a later date, and does not maximise the power output of the space.
It’s also important to bear in mind that regardless of claim, no solar panel technology will produce a significant amount of power in full shade. Learn more about monocrystalline vs. thin film panels.
Solar panel mounting
Make sure that the roof, ground mounting or tracking system is engineer certified for the area you are in. For example, if you live in a cyclone prone area make sure the mounting system and mounting brackets are also cyclone rated. Quality systems are wind certified. After all you do not want your system to take off during a wild storm . The mounting system is a very vital component and some suppliers skimp on this item. Make sure you ask about wind certification, warranty arrangements and get copies of relevant documents.
Solar inverter efficiency
A power inverter is the box between the panels and your appliances that converts DC electricity from solar panels to AC suitable for use in your home.
Not all solar inverters are equal and inverter efficiency will have a direct impact on the amount of time it takes for a system to pay for itself. Look at the inverter efficiency before purchasing a system. Obviously, the more efficient the inverter the better. Less electricity will be wasted as heat during the conversion from DC to AC. Industry leading solar inverters for grid connect systems in Australia include SMA, Sungrow and Fronius. Be cautious of generic type brands.
Get a few solar quotes
It always wise to gather a few solar quotes when making a major purchase as you will find that prices vary widely between providers. But don’t be just swayed by price as inferior components can reduce the up-front cost of the system. However, they may wind up costing you more in the long run in terms of reliability and efficiency.
Avoid high pressure sales people
High pressure sales tactics are unfortunately common in the solar industry. Try not to make decisions on the spot, just ask the person to let you consider the offer. If it’s as good as they claim, it will still be a good deal tomorrow. Pressured decisions on the spot often turn out to be less advantageous in reflection.
High pressure sales people are only one of the pitfalls that may await you when you shop for a solar power system. Learn more about the potential issues and how to avoid them in our consumers guide to solar power – avoiding tricks and traps.
