A 500 watt (or 500W) is an extremely high output level for a single solar panel. In comparison, 350W to 400W is the standard for residential panels in 2022.
A half-decade ago, the average solar panel size ranged between 200 and 300 watts. It wasn’t until recently that we realised manufacturers had quietly worked nonstop to double these figures.
Solar technology is becoming increasingly powerful, as evidenced by the rise of 500 watt solar panels. We expect solar panel size, efficiency, and maximum power output to improve over time.

What is a 500 watt solar panel?
Under Standard Test Conditions (STC), a 500 watt solar panel has a wattage rating of 500 watts. A 500W solar panel will produce around 2kWh daily and 731kWh of annual power. Remember that the actual power output will vary depending on various factors. The 500W solar panels have module efficiency ratings of 21%.
The 500-watt solar panel is one of the most creative advancements in the solar business in recent years. The 500-watt solar panel was created to meet the energy production requirements of medium and large solar systems with fewer panels, resulting in increased efficiency and lower prices.
500W solar panel's price and performance
In terms of efficiency rating, temperature coefficient, or other specifications, 500W solar panels are generally no better (or worse) than standard residential panels. They have a higher wattage rating solely due to their size. A 6kW system with twelve 500W solar panels produces the same output as a 6kW system with sixteen 375W solar panels.
In other words, the system’s wattage as a whole is more important than the wattage of individual panels. The 6kW system with 375W panels will cost less while producing the same amount of solar power on your roof.
500W solar panels are mostly used in large-scale installations where the panel’s physical size is unimportant. Given the high cost of solar, it’s a good idea to set aside some time before installation to do some study. This way, you’ll know where you are in terms of pricing and whether or not there are any potential problems.
If you want to save money on your electricity bills, you’ll need panels that meet all or most of your energy needs. The good news is that Energy Matters can assist you in calculating the output of a panel per day by clicking this link.
What is the size of a 500-watt solar panel? (Cell number and size)
500 watt solar panels are typically constructed from 144 half-cut monocrystalline cells. A 500W panel has a typical footprint of about 27.5 square feet. Each 500W solar panel weighs approximately 71.2 lbs (32.3 kg).
Is it worth it to invest in 500-watt solar panels for your home?
500 watt solar panels have their uses, but not on the roof of your house. Because of their size and weight, they are neither practical nor cost-effective in most residential solar situations.
The size of your solar panels can impact your system’s effectiveness and savings. Whether a 500W solar panel is the best fit for you depends on your circumstances. If you have a larger residential or commercial property that wants to go green, a 500W may be worth investigating.
A 350-400W was the most popular choice for residential installation solar panels in 2022. This range provides the best balance of the three most important solar panel factors: size, cost, and efficiency.
The 500W solar panel will be a game changer in the Australian solar business. These panels are suited for both residential and commercial solar projects and cost slightly less than installing two 250-300W solar panels. Read more about the best Australian solar panels.
The 500 watt solar panel manufacturers
Several major solar panel manufacturers are now selling solar panels with capacities of up to 500 Watts or somewhat for residential and greater commercial use. It is listed alphabetically.
JinkoSolar Tiger Pro 72HC
The JinkoSolar Tiger Pro panels, launched in 2020 with a record-breaking power rating of up to 580W, were the second generation in the Tiger series. The first release was 530W and gradually grew to 580W, followed by 600W+ as manufacturing volume and cell efficiency increased, as most manufacturers do.
Tiger Pro panels are now available in various sizes to suit various applications, ranging from compact 54-cell 400W panels to large-format Tiger Pro panels with capacities up to 550W. The Tiger Pro series is based on the bigger 182mm cell format and has a 9 MBB Tiling Ribbon (TR) cell design with a high-purity N-type silicon cell base to reach up to 21.6% efficiency. In addition, the MBB cell design resulted in a reduced temperature coefficient of -0.35%/°C.
LONGi Hi-MO 5m
LONGi’s Hi-MO 5 large format panels are intended for commercial and utility-scale installations. Like the Hi-MO 4 range, these panels are built on the most recent monocrystalline PERC cells with multi-busbar (MBB) half-cut cells. The Hi-MO 5 range, available in 66-cell and 72-cell sizes, also employs the latest gallium-doped silicon, which reduces the effect of light-induced deterioration from 0.6% per year to roughly 0.45% per year, resulting in just 11% to 12% loss in power after 25 years plus the initial 2% in the first year.
SunPower Performance 5
The Performance series panels employ a unique shingled cell architecture with six long strings of shingled cells running parallel like SunPower Performance 5. This design is less expensive and provides higher shade tolerance when partially shaded. The thin solitary PERC cells, based on common P-type silicon, are more flexible and less prone to micro-cracking, which is a common problem with full-size square cells. The P series comes in three sizes: the smaller residential panels rated from 370W to 390W, the larger format commercial panels rated from 405W to 420W, and the extra-large utility size panels rated from 475W to 500W.
