Why are solar cells in solar panels getting larger in size Part
The solar cell is the basic unit in a solar panel used to convert sunlight into electricity. As technology continues to improve, the size of solar cells is becoming progressively larger. The following are the main reasons for this:
Increased power output
With the rapid growth of the solar industry, outdoor solar panels need to produce more electricity to meet people's needs. Larger solar cells can collect more solar energy and produce higher voltages and currents, thus increasing power output. In addition, larger cells also mean that fewer cells can be placed in the same area, thus reducing the inherent internal resistance and further increasing power output.
Reducing manufacturing costs and saving space
Increasing the size of solar cells over time not only increases their power, but also directly reduces the cost of solar panels. By utilising larger cells, panel manufacturing costs can be reduced, capacity optimised and costs reduced. In addition, larger solar cells are more integrated and easier to install and maintain than smaller cells. This makes these larger cells ideal for use in locations where environmental space is limited or expensive, such as rooftops or space operations.
Improving the efficiency and performance of equipment
The size and shape of the cells placed in different solar panels varies. As the size of solar cells increases, manufacturers can improve the power density and PV conversion efficiency of their equipment by making appropriate updates to the arrangement of the modules. Of course, this also requires that we choose where to place the solar panels to ensure that they can face directly into the daylight to maximise the performance and efficiency of the panels.
Improving performance and reducing losses
The performance of a solar panel depends not only on the quality of the device, but also on the energy losses caused between the components inside the panel. Smaller cells need to be connected several times to form a panel.
The inclusion of internal components such as these connectors and wires affects the performance of the cells. Larger solar cells, on the other hand, allow for fewer connections to be made to form a panel, providing a smoother flow of current through the circuit and providing higher efficiency and performance for the solar panel.
In summary, the increasing size of solar cells helps to increase power output, optimise production capacity to reduce costs, increase energy density and reduce energy losses, among other things.
