Solar panels represent the future of energy. However, the maximum recorded efficiency of a commercial solar cell is 33% due to certain energy barriers at the molecular level. "I''d put my money on the sun and solar energy. What a source of power! I hope we don''t have to wait until oil and coal run out before we tackle that."- Thomas Edison
Solar panel efficiency is the percentage of the sun’s energy that is converted into electricity. It is the ratio of power out divided by power in. for example, a 100-watt panel with an efficiency of 16% would have an output of 16 watts. The efficiency of the single-junction cell has limited the efficiency of solar panels.
Low efficiency reduces the output of solar cell and enhances the levelized cost respectively. Index Terms— Amorphous silicon solar cell (a-Si), Efficiency of solar cell, Maximum power point tracker (MPPT), Monocrystalline solar
Thick layers of snow can directly block sunlight accessing solar panels and cut efficiency down to zero . It is important to know that most solar panels can still work with a layer of three to four centimeters of snow (approx. 1.5 inches). If the layer is thicker than that, you should remove the snow.
Solar cells are sensitive to warmer temperature. Higher temperature outside means that the semiconductor material of solar panels gets hot quickly and slightly changes properties, which is linked to electrical losses and voltage drops.
The problem with solar cell efficiency lies in the physical conversion of sunlight. In 1961, William Shockley and Hans Queisser defined the fundamental principle of the solar photovoltaic industry.
Solar panels do not have the best area ratio to electrical power output – they absorb less light than a flat surface with the same area. This is due to only a specific wavelength range absorbed by silicon and other materials used for solar cell production.

Solar cell efficiency represents how much sunlight is converted into electricity, with early solar panels having 8-10% efficiency compared to 40-55% for traditional energy sources. Advancements have increased solar cell efficiency to 15-22%, but this is still limited by the Shockley-Queisser limit of 33.7% maximum efficiency.
To understand why your solar panels are not producing enough power in detail, take a look at the reasons mentioned below. 1. Sunlight Obstruction.

In the end, this translates into less irradiance received by solar panels, and therefore, generation of less power. The idea is to reduce the thickness of these wires, or in the best case to eliminate their interference with the sunlight by placing them on the back of a panel.
Let us assume the solar capacity factor is 20%. So, you will get power equal to 1000 W × 0.20 = 200 W. The number is sad to believe, but it is true. You need to have five solar panels to generate the power equivalent to one solar panel. That is why a low capacity factor is a major problem in solar technology.
