Technological progress in photovoltaic production makes producers outdo themselves in optimizing PV energy production. An expression of this development is the change in the size of the photovoltaic cells that make up the photovoltaic panels. The growing size and number of cells in one photovoltaic module allow for obtaining more output power from a single photovoltaic panel. The list below presents modules above 600W, so they are almost twice as powerful as the 300W panels a year ago.
The size, weight and power predispose the 600W-700W modules to large-scale projects such as solar farms and large business installations.
Key elements when choosing the most powerful solar panels?
When analyzing individual high-power modules, the following should be taken into account:
Dimensions: that is, how big is the photovoltaic panel and take these parameters into account, both during assembly and logistics.
Power: how much energy will the photovoltaic panel produce both from the front and from the bottom in the bifacial version?
Warranty: This is the guarantee that the manufacturer gives for the photovoltaic panel, its output power after 25 or 30 years and, last but not least, the percentage after the indicated period.
Technologies: types of photovoltaic cells, their arrangement and the way of cutting give many combinations that will make the photovoltaic module work better or worse.
Bifaciality: the energy generation in the back of the module, mainly from reflection.
Double glass: whether the photovoltaic panel is protected by a glass coating on both the front and back.

Currently, the largest photovoltaic panels most often have dimensions in the range of 2384x1303x35 mm. This means a much larger production area per one-generation unit, and thus such modules are especially predisposed to large solar projects (photovoltaic farms).
The dimensions of the entire module mainly consist of the number and dimensions of photovoltaic cells.
Of all the bifacial panels currently available on the market,Mysolar HJT 710W, Mysolar Shingled (670W), HJT Akcome and Huasun (700W) and Jolywood N-type (700W) are the largest and most powerful photovoltaic panels. The power generated in the range of 670W – 800W makes these modules ideal for large land and roof investments in companies and for large photovoltaic farms.
Mysolar shingled, Huasun, Akcome and Jolywood are also the largest high-efficiency solar panels enclosed in double glass (glass-glass technology). Thanks to this, resistance to salt mist, industrial pollution and ammonia is the highest on the market.
An additional advantage is increased fire resistance, which makes double-glass panels the safest in this category.
In the list of the largest Solar Panels on the market, the product warranty is:
12-15 years for most manufacturers.
Against this background, the longest Mysolar warranty of 30 years, the optional AKCOME 25 years and 20 years of Swiss Solar stand out.
For the linear power loss warranty, 30 years for glass-glass modules and 25 years for plastic backsheets are characteristic.
Another important parameter that proves both the production and technology of the cells is the guarantee for the output power after 30 years.
In this category, the highest parameters are achieved by:
The rest of the PERC panels are approximately 85% after 30 years for glass-glass modules.
Thanks to the large area of photovoltaic cells and enormous power, Mysolar Gold solar panels are ideal for roof and land investments. Solar farms using GOLD panels save:
Thanks to the use of the largest shingled Mysolar photovoltaic panels, savings of up to 20% are possible
