Brief Introduction.
HT72-166M series PV module insists of 144 pieces half-cut monocrystalline solar cells, and its power output can be up to 435W/440W/445W/450W/455W. We use big 166mm mono perc cells for this type, so it is the most efficient module we have at present. And we have arranged 2 production line for this size of tier 1 list solar panels . Moreover, its module efficiency can be 20.40% and it is usually used in developed markets. All modules are sorted and packaged in arry, reducing the loss of inadequacy and maximizing system output.

Q&A.
Q1:The Later maintenance is laborious and laborious. If I encounter any disaster, I will lose money.
A:If qualified products are strictly selected, the system integrator can essentially guarantee that there will be no additional maintenance costs in the future.
Most branded companies offer limited electricity generation guarantees for manufactured photovoltaic modules, and the weakening of energy production within 20 years will not exceed 20% of nominal power.
Q2:In order to prevent the photovoltaic modules from being hit by heavy objects, can you install a wire protection net for the photovoltaic array?
A:It is not recommended to install a wire protection network.
Because the placement of wire-protected networks in the photovoltaic network can cause partial shadows on the components, create a hot spot effect and affect the efficiency of the electricity generation of the entire photovoltaic plant.
In addition, because qualified photovoltaic modules pass the ice hockey impact test, there is no need to install safety nets under normal conditions.
Q3:How to choose Silicon PV Module?
A:When we buy a solar module, we pay attention to the power of the solar cell.
In general, the power of the solar panel is proportional to the field of the solar chip.
The area of solar cell wafers is not exactly the same as the area of the solar panel, since although some solar panels are large, the gap of the unique arrangement of solar wafers is very wide, and the power of these solar panels is not necessarily high.
Q4:What is the daily power generation per kilowatt of photovoltaic projects?
A:It should be divided into regions and the energy production capacity of each region is different. This is due to the fact that the climate is different everywhere, the average annual temperature is also different, and the frost period is also different. The National Weather Service has an average annual daylight hours for each province, and each province's installation angle must be mounted on a constant slope based on local geographic coordinates. The special calculation method is that the intense solar clocks multiplied by the installed capacity of the photovoltaic plant are the maximum theoretical energy production of the photovoltaic plant.
Q5:How to clean photovoltaic modules?
A:The rainwater can clean without special maintenance and cleaning. If you encounter adhesive dirt, simply wipe it.
