Solar has changed the way homeowners and commercial business owners use power to cater for their energy needs. The sudden shift from fossil-fueled electricity to clean-sourced energy has resulted in almost 5 in 3 Australian households installing and using solar PV panels. However, homeowners thinking of transitioning to solar have one common question - will it be efficient enough to fulfil their everyday energy needs?
This blog answers all your questions related to solar efficiency and factors that may affect the performance of panels. Let’s first understand:
The amount of solar energy converted into electricity by a solar cell through photovoltaics is known as the solar cell's efficiency. The annual energy output of a photovoltaic system is determined by the solar cells' efficiency, latitude, and climate.
On the other hand, efficiency becomes significantly more crucial when fossil fuels are used as energy inputs for power generation. Relying solely on this indicator can be dangerous. Also, solar panels have no operating costs or emissions.
Most leading solar manufacturers continually invest millions in research and development to enhance their photovoltaic cells. The photovoltaic material, overall wiring, and design of the module affect solar cell’s efficiency. Since monocrystalline cells are made of single, highly pure silicon crystals, they are more effective. Polycrystalline cells, on the other hand, contain multiple crystals, which reduces their effectiveness. This does not imply a lower level of quality for polycrystalline solar panels. Due to the characteristics of their materials, they have a lower conversion efficiency, but both types of solar modules are available in high quality.

To ensure the solar panels are as efficient as possible, certain factors should be cosidered..
To determine the solar panel's maximum efficiency, the ratio of panel power to solar power must be divided by the panel's square metre area, which must then be multiplied by 100 to obtain a percentage. Ensure that all of the values' measurement units are accurate to avoid receiving unexpected results.
Currently, most solar panels have an efficiency of between 15% and 20% with outliers on either end of the spectrum. Similarly, most photovoltaic panels available have an efficiency of no more than 20%, though high-efficiency solar panels can occasionally exceed this (and almost reach 23%). It's important to note that more expensive panels with higher efficiency will help you meet your energy needs, particularly if you have a small roof and little room.
A solar cell's surface will reflect some photons that strike the cell. Some of the absorbed photons have their energy converted into heat instead of electric current by internal recombination. These efficiency reductions are unavoidable.
