TOP 6 Reasons Why Are Solar Panels So Inefficient?

Solar energy usage has been increasing recently, and homeowners are powering their homes with solar panels

As a present or future solar energy consumer, you should know why solar panels are so inefficient?

Solar energy decreases electricity costs and creates possibilities for renewable energy sources by reducing fossil fuel energy consumption.

Inefficient solar panels can reduce the energy production rate and create unwanted situations.

So, after proper installation, it is important to ensure the efficiency of solar panels.

Here, we would like to present a list of some significant reasons why solar panels are inefficient.

Why Are Solar Panels So Inefficient?

Solar panels can be inefficient if they get covered up in the snow, ice, dust, or other environmental issues.

The solar system depends on the sun and requires sunlight. If the weather is terrible and there is not enough sunlight, the solar panels can’t produce sufficient energy.

Similarly, dust or snow can cover the surface of the solar panels and prevent the focus of sunlight.

Excessive dust can hide the photovoltaic cells and create obstacles between solar panels and the sun.

Besides, the design and configuration of solar panels may affect the production rate.

A perfect design will make your solar panels efficient, and you will get desirable energy from the source.

However, a correct configuration enhances the possibilities of energy production at a great rate.

In the same way,  imperfect mirrors and lenses can create unwanted situations. 

If you install a solar system with imperfect lenses and mirrors, it can’t produce the necessary energy and make your panels inefficient.

Snow, Ice, and Dust

Snow can affect the energy production rate of a solar system. A thick tier of snow can block the ray of the sun and create a barrier between the sunlight and the surface of solar panels.

For this reason, your solar system will reduce the energy production rate and provide you with less power. 

You may know that solar panels can produce electricity even with four-centimeter layers of snow. 

But you should be concerned about excessive ice and snow to save your solar panels for further use.

Dust and dirt are not harmful to solar panels because solar panels come with dust-proof technology. 

They can not destroy the structure or cells of the solar panels but make them inefficient.

Solar Panel Type

There are three major types of solar panels. These are monocrystalline panels, polycrystalline panels, thin-film solar panels.

Every individual type has a different efficiency rate. Monocrystalline panels are 22 to 27% efficient.

Polycrystalline solar panels have an efficiency of between 15 to 22 percent. 

Thin-film solar panels can generate up to 13% solar energy.

So, the efficiency of solar panels depends on the type of solar panels and their category. 

If you select a solar panel type that has low efficiency, then you will get less power. 

For this reason, you have to select the most efficient solar panels and consult with the service provider for better understanding. 

Configuration and Design of Solar Panels

The overall efficiency of solar panels relies on the configuration and orientation of solar panels towards the sun. 

The mounting system is very important while installing solar panels. Besides, a perfect configuration will enhance efficiency and generation rate.

Your solar panels will generate more power when it absorbs plenty of sunlight and focus on the sun. So, the focus of the solar panel can change the energy production rate.

South-facing solar panels have sun access all day long. If you mount your solar panels in this position then, it will be efficient. 

On the contrary, the wrong mounting option will reduce the production capacity.

In the same way, the design of the photovoltaic cells can affect the energy production rate. 

Imperfect Mirror or Lenses

Solar panels are covered with a mirror-type thin glass to make them waterproof.

If you install solar panels with faulty glass mirrors or lenses, the photovoltaic cells will reduce energy production.

The setup of solar panels needs to be perfect and professional. If you install solar panels in the wrong way, they can not produce the maximum energy.

Sometimes, solar panels reduce production due to unwanted carrying damage.

You have to ask the service provider to install solar panels after ensuring their function and efficiency.

It will provide you with continuous energy and make your system more efficient.

Environmental Conditions

The idea that higher heat will produce more energy in a solar system is not correct.

High temperatures will create electrical loss and drop the voltage. In the same way, solar panels require standard heat to produce electricity.

Excessive heat can damage the seal and wiring of the solar panels.

Twenty-five degrees is the standard temperature for generating energy from the sun, and above this temperature, the system will reduce the energy production rate up to 5 percent.

Temperature above 60 degrees will reduce the energy production rate by up to 17 percent.

So, the effect of temperature and hot weather is important for countries with a hot climate.

Insulation Resistance

The insulation resistance process can affect the solar panel’s efficiency. It can bring a significant change and block constructional leakages too. 

Besides, unauthorized insulation resistance will damage the solar panel instead of protection.

So, you have to select a perfect insulation and maintenance process to get sufficient energy from the solar panels.

You can ask the service provider to get an authentic insulation resistance system during the installation.

Snow, ice, dust, solar panel type, configuration and design of solar panels, imperfect mirror or lenses, environmental conditions, and insulation resistance can make your solar panel inefficient.

Wrapping Up

Altogether, when it comes to specific reasons to the question, why are solar panels so inefficient? The answer is not clear, and the matter doesn’t contain any particular reason.

It is better to understand the possible reasons and get a complete solution by discussing the most common contention. 

You have to think technically and apply the solution technologically. It will make your solar system efficiency and provide you with better service.

  1. Solar will never replace electricity. In the future they will regret using solar because it will all be old, collapse and way to costly to replace. The Solar companies will go right back to charging high electric prices like power companies it is just a gimmick to get everybody to buy on to this solar panel gimmick that will never be the same as electricity. If it aint broke dont fix it. Just another way for law makers to line their pockets and screw everybody else.
