Complete overview of Panasonic solar panels
You probably know Panasonic from TVs, devices or cameras, but Panasonic is also a leader in solar technology. The panels are highly effective in all weather conditions and come with an impressive 25-year warranty. In terms of cost, Panasonic does not have the cheapest solar panels, but given the high quality you always get excellent value for money.

How to compare Panasonic solar cells with competitors
When comparing a solar panel, it is important to take into account energy efficiency, high temperature operation, capacity and warranty. Panasonic performed well in all four categories and held its own with other leading solar panel manufacturers such as SunPower. Below is a more in-depth examination of each of the four factors on which we have focused.
Energy efficiency
Solar panels are classified in an energy efficiency class, which indicates the amount of sunlight that the module converts into electricity. The efficiency can vary between 11 and 22%, with a higher figure indicating that solar panels are more efficient. It is still not as efficient as many more traditional forms of energy, but the manufacturers of solar panels, including Panasonic, have come a long way over the years to fill this gap.
Panasonic solar panels are at the top of this spectrum, with efficiencies between 18 and 20%. It is in the process of gaining a place among the leading manufacturers of solar panels. It should be noted that these figures represent the maximum efficiency of your solar panel under ideal conditions. If it is cloudy, rainy or too hot (see below), you cannot get this kind of energy from your solar panels.
High temperature performance
Solar panels are not as efficient if they do not receive enough sunlight, but their efficiency can also be reduced if they are exposed to too much sunlight. As soon as the temperature of the solar panel exceeds 25 degrees Celsius (77 degrees Fahrenheit), it will no longer be able to convert sunlight into electricity as efficiently as at lower temperatures. The resulting loss of efficiency is determined by the temperature coefficient.
The coefficient is generally -0.40% per degree Celsius. This means that for each degree Celsius, if the temperature of the solar panel is higher than 25 degrees Celsius, the efficiency of the solar panel decreases by 0.4%. For example, the yield at 26 degrees Celsius will only be 17.6% instead of 18%. And if temperatures continue to rise, the efficiency of the solar collectors will continue to decline.
Panasonic solar cells have an average temperature coefficient of approximately -0.29, which is one of the lowest temperature coefficients of all solar cells currently available on the market. This is good news for people who live in a warm climate, because Panasonic solar panels will continue to work with maximum efficiency, even if the temperature rises.
Power
The voltage is a measure of the amount of energy a solar panel can produce. Solar panels generally have a power output of 250 to 400 W, and a higher power output is generally preferred because it can deliver more. But it is important to look at this figure in combination with efficiency. Two solar panels can have the same output, but with different efficiency and therefore different dimensions. A less efficient solar panel will be larger than a more efficient solar panel with the same capacity, and the size of the solar panel can be a problem if space is limited.
Most Panasonic solar cells are between 300 and 330 watts, which is slightly higher than the industry average. The power of your solar panel helps determine the number of solar panels you need, while more powerful solar panels enable you to recoup your installation costs faster.
Warranty
Solar panels are not cheap to buy or repair, therefore most solar panel manufacturers offer guarantees to protect your investment. If the solar module breaks down during the warranty period, the manufacturer will repair it free of charge or replace it with a new one. A 10-year warranty is the industry standard, but Panasonic offers an impressive 25-year warranty on all its solar panels when registered online within 60 days of installation.
Solar panels also have a power guarantee, which shows how the solar panel will continue to function over time. Panasonic guarantees that its production capacity will be at least 97% of its maximum capacity in one year and will not decrease by more than 0.26% per year over the next 24 years. This means that your Panasonic solar panels will have an efficiency of more than 90% in 25 years’ time. Only a few other manufacturers of solar panels can keep this promise.
How much do Panasonic solar panels cost?
The cost of solar panels is usually measured in dollars per watt. The average cost of solar modules is about $3 per watt, and Panasonic solar modules are in that range. You can pay between $2.70 and $3.35 depending on the panel you choose and how you install it. Solar panel holders and inverters also play a role in the total cost of your solar panel system and the number of solar panels required. Where you live can also influence the cost of installing a solar power system.
It’s not uncommon for homeowners to spend between $10,000 and $20,000 on a solar system, but you can recoup some of that if you qualify for solar collector discounts, state and federal tax breaks, or other incentives. Take a look before buying Panasonic solar panels and compare installation prices of different installers to reduce your costs.
How to find the best solar collectors for you
Although all Panasonic solar panels are made of high quality materials and are supported by a leading warranty company in the industry, this is not the case. Choosing the right solar panel for your home depends on your budget, the space you have available and the amount of energy your system needs to produce.
Local specialists in solar installations can answer all your questions and estimate the costs of the Panasonic system or recommend the best solution for your individual needs.
You can easily compare the quotes by answering a few short questions.
You will probably work with a solar panel installer who will help you determine how many and what type of solar panels are most suitable for your home. Panasonic’s high quality panels are an excellent choice for homes of all shapes and sizes, but especially for large homes that require high energy efficiency and for homes in hot climates that need to worry about excessive heat that can affect the performance of their solar panels.
It’s tempting to focus on cost, but base your decision mainly on the four factors mentioned above – energy efficiency, high temperature performance, performance and warranty. These factors indicate the quality of the solar module and its long service life. The price is important, but if your solar panels don’t last long or don’t work as expected, you’ll still have to replace them with new ones, which means you’ll have to spend even more money.
Review and compare the options and prices of different installers to make sure you get the best possible deal before you decide. If you are not sure how much of your solar budget you can estimate the cost of your solar panel system at .
