As mentioned before, there is a formula to estimate the power of a solar panel based on its surface area: Estimated solar panel power = surface area (length x width) * CTM value * conversion efficiency per cell*number of cells. From this formula, we can conclude that the size of a solar panel is related to its surface area and the conversion efficiency within the solar cells, which affects the panel's power.
The size of the solar panel depends on what it is used to charge, as well as the amount of electricity needed by the device each day. If it is difficult to calculate the energy consumption per day, you can calculate it based on the monthly usage and then calculate the daily usage. For example, when calculating the number of solar panels needed for a roof, we can easily calculate the number of panels required by multiplying the energy consumption per hour by the daily sunshine exposure on the available roof area, and then divide the result by the wattage of the solar panel.
In general, the conversion efficiency of mass-produced monocrystalline cells is around 23.5%-25% (actual conversion efficiency varies depending on the type of solar cell). Other conditions being equal, a higher conversion efficiency of solar cells means a smaller surface area for the solar panel, while a lower efficiency means the opposite.
The available roof space for solar panels and the amount of sunlight that reaches it are critical factors for determining energy output. Trees, adjacent buildings, chimneys, and other structures can reduce the output of the panels. Solar installers will conduct a thorough shading analysis during the free quotation process.
The higher the power, the more expensive it is naturally. The higher the conversion efficiency, the more expensive it is for the same area. Of course there are a number of other factors that affect the price of solar panels.
Whether it is "peak carbon" in 2030 or "carbon neutral" in 2060, the world is strongly supporting the application of new energy sources. High power and high conversion modules cover the full size of the market and can be easily customized to meet market needs. You can find the solar panel you want at Hao Yu PV. Our modules have an annual capacity of 2GW, compatible with the market mainstream P-type (PERC), N-type modules (TOPCON), and will produce heterojunction modules in the coming year. Our current production capacity is mainly for M10 (182mm) series products.
M10 module - Neptune series N-type model 72 version module maximum power 585W, power generation efficiency 22.67%, 30-year linear power output 87.4%.
All-black modules based on M10 (182mm) cells, supplying European energy market is expected to exceed 1,000,000+ households, holding a certain market share in Europe, such as the Netherlands, Germany, Belgium and other countries, the PV star on the roof, true all-black, true architectural aesthetic integration. The quality of Hoyu's all-black module process has passed the TUV test and has been awarded the invention patent.
