Summers are great as you enjoy vacations, there are many activities which we Indians align during summers, and we all have our unique stories related to summers. But along with these perks we also have to bear heat which allows us to operate many gadgets such as coolers, Air conditioners, fans and one thing which brings chills are electricity bills.
To rescue from such a situation, people do have a solar PV system, but we always wonder will summers affect the efficiency of solar power system? Let us understand about that today:
Will summers affect the efficiency level of solar panels?
It is a major misconception that people believe that the stronger the sunlight leads to more power generation by solar module, but that is not true. Temperature affects all electronics in the system, and solar panels are no exception, while as the temperature rises, the panels generate less voltage and become less efficient in producing electricity.
Electrons present in a relaxed resting state when photon kicks them out of the atom on a cooler day and gets more energized. Hence it is a difference, from low energy to high energy, establishes a high current.
On a summer day, the situation is not the same here. The heat within the panels already includes the electrons into an excited state. They won’t involve much energy when the photons dislodge them. But still, though a solar panel can get the same amount of sunlight on a cool day or a hot day, the panels will produce more energy on a cool day.
For example, solar panels do not start losing their efficiency until the temperature rises to 77 degrees. With each degree increase in temperature above 77 degrees, a solar panel reduces its efficiency by the rate of its temperature coefficient.
Ways to reduce the negative effects of high temperature
As we know that too much heat creates problem inefficiency of solar panels; hence below, we list down ways to beat the heat:
1.Select the correct solar panel
The primary step is to choose solar panels with a low-temperature coefficient where most monocrystalline and polycrystalline photovoltaic panels offer a temperature coefficient between -0.35 and -0.5.
The thin-film panel is also a kind that can handle the heat, offering a temperature coefficient of between -0.2 and -0.25. They have a much lower efficiency rate than PV panels, usually between 11-13% efficiency.
2.High-quality installation
It is tough to prevent reducing the solar panel efficiency during the summers. The best solar installation company in Delhi can install your panels to maintain the cool as possible to limit efficiency loss.
Mounting your panels a few inches above the roof ensures the airflow between the panels and the top can help prevent a hot roof from heating your solar panels.
3.Solar system correct size
Your solar installation specialist may suggest you a slightly larger solar power system that ensures efficiency loss during days with high temperatures to endure long and hot summer months.
