Solution

Solar cell panels are used to harness solar energy. However, there are still some limitations with solar cell panels, which are listed below.
The solar panels use semi-conductors (made up of silicon). The cost to produce pure silicon is very high.
The efficiency of the panels for the storage of electricity is not sufficient.
Silver is used in the panels as a soldering material which is very costly.
The solar panels require proper maintenance periodically.
