Subtle shading that covers a few cells or a single panel can reduce solar energy production by 50% or more. Look for solar panels with high power output and high efficiency.
Solar Cell Efficiency Explained. Cell efficiency is determined by the cell structure and type of substrate used, which is generally either P-type or N-type silicon, with N-type cells being the most efficient. Cell efficiency is calculated by what is known as the fill factor (FF), which is the maximum conversion efficiency of a PV cell at the optimum operating voltage and current.

The polycrystalline cells are slightly less efficient (~12%). These cells can be recognized by their mosaic-like appearance. Polycrystalline cells are also very durable and may have a service life of more than 25 years. The cons of this type of PV technology are mechanical brittleness and not very high efficiency of conversion.

A solar cell is made of semiconducting materials, such as silicon, that have been fabricated into a p–n junction. Such junctions are made by doping one side of the device p-type and the other n-type, for example in the case of silicon by introducing small concentrations of boron or phosphorus respectively. In operation, photons in sunlight hit the solar cell and are absorbed by the semic…

However, the most dominant type of PV cell used in large-scale applications is still crystalline silicon, which is the same basic technology as used in the 1970s. This is partially due to the high availability of low-cost silicon PV panels that have prevented new and emerging cell types from gaining a significant presence in the PV market.
The construction of a solar cell is very simple. A thin p-type semiconductor layer is deposited on top of a thick n-type layer. Electrodes from both the layers are developed for making contacts. A thin electrode on the top of the p-type semiconductor layer is formed. This electrode does not obstruct light to reach the thin p-type layer.
Photovoltaic cells, commonly known as PV cells, are thin layers of pure silicon that are impregnated with tiny amounts of other elements such as boron and phosphorous. When exposed to sunlight, they produce small amounts of electricity. They have been around since the 1950s, and were initially used as a power source for satellites in space.
