The rapid development of solar technology from the previous very low power solar panels to the 400W solar panels that are now common in home solar systems is a big breakthrough. However, as technology advances, higher output solar panels have been developed. Currently, the largest wattage solar panel on the market is 700W.
The highest wattage solar panels are designed for higher power output. The amount of light energy that a solar panel converts into electricity (power output) is determined by the wattage of the solar panel and its efficiency. For the same solar panel, the higher the wattage, the higher the power output.
Nowadays, the highest wattage solar panels 700W solar panels, which are mainly used in large commercial facilities, solar power plants, and so on. Most home solar systems are more common with 300W 400w 550W.
With the optimized design of solar panels, their wattage is getting higher and higher. Currently, the main way to increase the wattage is by increasing the size of the solar panels. 700W solar panels are larger compared to 400W solar panels, which can accommodate more photovoltaic cells, thus increasing the wattage of the solar panels. It is not a technical improvement or enhancement.
The performance of a solar panel is mainly determined by its efficiency. The manufacturing process for high wattage solar panels and low wattage solar panels is roughly the same. Taking more efficient polycrystalline and monocrystalline solar panels and half-cut photovoltaic panels with multiple busbars can improve the current and lower the resistance, thus increasing the conversion efficiency of solar panels. Coupled with its own higher wattage of solar panels, thereby increasing the output power of solar panels.
4.11 Higher power generation efficiency increases the power output. Higher wattage solar panels tend to be more efficient than lower wattage solar panels, so the output power is higher and so is the amount of power generated. They are suitable for large-scale power generation applications.
4.12 Lower average price per watt for faster return on investment. Higher wattage solar panels emit the same amount of electricity as lower wattage solar panels. 700W solar panels require fewer panels, and although 700W solar panels are more expensive, they are cheaper overall. Also, a solar system constructed with 700W solar panels may require fewer construction materials and be cheaper to install than a solar system constructed with 400W solar panels.
4.13 Ease of use for solar power plants and large-scale applications. A single 700W solar panel is larger and more cumbersome to lay out than a 400W solar panel, but for large-scale applications, there is often ample space to install solar panels. And compared to installing lower wattage solar panels, the output of the same power, the overall size is smaller. It is possible to utilize the same space to install more solar panels and increase power generation.
4.21 solar Inverters and converters for solar systems may have to be upgraded to accommodate higher wattage solar panels, which can be slightly more expensive, but this is nothing compared to the cost.
4.22 Not suitable for family homes with complex roof structures. The large area occupied by a single 700W solar panel is not conducive to use in homes with a large number of chimneys or other objects that limit the available roof area.
4.23 There may be increased transportation costs. When using containers to transport solar panels. Containers are often suitable for the transportation of 550W solar panels, which can make ample use of container space to reduce transportation costs.
However, for our household electricity consumption. Generally do not use so many panels, so when using the container transportation, the space is quite sufficient, so there is no difference between 550W and 700W.
But for large-scale applications, so many solar panels are often needed. Then in the transportation of 700W solar panels will be a waste of container space and increase the cost of transportation.
If you have ample roof area or you are planning to install on the ground and you have a high demand for power generation, then installing the highest wattage solar panels is right for you. A solar panel that outputs the same amount of power has fewer solar panels, and despite the larger individual panels, it’s still a smaller area overall to install 700W solar panels. This allows you to install more solar panels in the same area. Increasing the amount of electricity generated pays for itself more quickly in terms of cost effectiveness.
If your home has more chimneys on the roof or a complex structure is not suitable for installing a large area of 700W solar panels, because it will be a bit troublesome in the layout. Then, you can choose to install a smaller area of 400W solar panels, it is more conducive to the layout and can make use of the narrow space, you can also install multiple panels, thus increasing the amount of electricity generated.
