At the end of 2020, about 2.7 million households in the US are using solar panel systems.
There are many factors to consider when purchasing a solar energy system in your home. But, none is more important than the solar panel efficiency rating used to determine the amount of energy you will produce.
Suppose you don’t know how to choose, we are here to help you.
Here is everything you need to know about the solar energy efficiency rating.
What Solar Energy Efficiency Means
Solar energy efficiency measures how well a solar panel converts sunlight into electricity. The higher the rating, the more efficient the panel is.
Solar panels with a higher efficiency rating will produce more electricity than panels with a lower rating. Choosing a panel with a high-efficiency rating is essential if you want to maximize your solar energy production.
If you are thinking about installing a solar energy system, be sure to go with trusted companies like Blue Raven solar company. Professional solar energy companies can ensure their clients in getting an energy-efficient installation.
What Affects Solar Panel Energy Efficiency Rating
Several factors determine solar panel efficiency ratings. It is something you should be aware of when having an installation done. Here are some of the things that affect the efficiency of solar panels:
Solar Cell Type
There are three main types of solar cells. These are the monocrystalline, polycrystalline, and thin-film solar cells.
Monocrystalline solar cells are from a single silicon crystal. They are the most efficient type of solar cell.
Polycrystalline solar cells are from multiple silicon crystals. They are less efficient than monocrystalline solar cells.
Thin-film solar cells are the least efficient type of solar cell. They are made from a thin film of semiconductor material.
Busbars and Wiring
Busbars are metal conducting strip that connects solar cells. Wiring is what combines these busbars to create an electrical circuit. The thickness of the busbars and the quality of the wiring can affect the solar panel’s efficiency rating.
The thicker the busbars, the better the electrical conduction, and the higher the efficiency rating. The quality of the wiring also impacts the rating, with better quality wiring resulting in a higher rating.
The higher the temperature, the lower the panel’s efficiency. Selecting a panel designed to operate at high temperatures is essential to ensure optimal efficiency.
It is also essential to ensure that the panel installation is in a location that receives a significant amount of sunlight. This will help keep the panel cool.
Solar System Angle
The panel’s angle relative to the sun affects how much energy it can capture from the sun. The steeper the angle, the more power you can collect. The optimum angle for solar panels in the northern hemisphere is around 30-40 degrees from vertical.
Get More Energy with an Efficient Solar Panel System
A solar energy efficiency rating is a great way to determine the potential of solar panels. The higher the rating, the more efficient the solar panel is.
Solar panels with a high-efficiency rating can produce more electricity with less sunlight. This makes them an excellent option for those who want to reduce their dependence on fossil fuels.
