How Energy Efficient Are Roof Solar Panels?

We know that solar panels are growing in popularity as more people become energy conscious and pursue energy-efficient alternatives to traditional energy sources. But how energy efficient is a residential solar panel installation, really?

In this article, we’ll explore the factors that contribute to energy efficiency in solar panels and how homeowners can maximize their energy output.

How Efficient are Solar Panels?

There is no definitive answer to this question, as the efficiency of solar panels can vary greatly depending on a number of different factors. Generally speaking, the average solar panel is between 15% and 18% energy efficient, meaning that only 15% – 18% of the sunlight that hits them is converted into electricity. This means that for every 100 units of sunlight that hits your roof-mounted solar panels, you’ll only be able to generate 15 – 18 units of usable energy.

However, there are several factors that can affect the efficiency of your solar panels and increase or decrease their effectiveness.

Factors That Affect Solar Panel Efficiency

When it comes to solar energy, one of the most important factors to consider is the size of the system. You may require 10kw solar systems or 6.6 kw solar systems, depending on how much energy you use and the size of your roof. There are many different factors that will affect how efficient your panels are. Some of them are external, while others are internal. If you’re not too sure if you have the space for this to be an efficient option for you, consult with a roofer or solar panel expert so they can confirm this for you.

Here are just a few of the internal factors which will affect your panels.

  • Solar panel age: Older solar panels will generally be less energy efficient than newer models. This is due to the fact that they degrade over time and lose some of their ability to absorb sunlight.
  • Type of solar panel: Different types of solar panels have different energy efficiency rates. Monocrystalline panels are typically considered to be the most energy efficient, while polycrystalline and amorphous panels are not quite as effective.
  • Solar panel materials: The material your solar panels are made out of can also affect energy efficiency. Those made from materials like cadmium telluride or copper indium selenide tend to be more effective at energy absorption than those made from silicon.

These aren’t all of the factors which may affect your solar panels’ ability to provide your home with clean energy, but these are the factors that directly affect the panels’ efficiency.

When determining the energy efficiency of solar panels, it’s essential to consider not only their material but also their specific characteristics. To assess the performance and potential energy output of different panel types, tools like the PV Watts solar panel calculator can be invaluable. This calculator takes into account factors like panel material, location, tilt, and orientation to estimate the energy production of your solar system accurately. By utilizing such tools, you can make informed decisions to maximize the efficiency and cost-effectiveness of your solar installation.

Other Factors That Affect Solar Efficiency

Now let’s talk about some of the other factors that can affect the efficiency of your solar energy system. These factors don’t affect the efficiency of the panels themselves, but they can have an impact on energy production overall.

  • Solar plans: The type of solar plan you have will affect the efficiency of your system. For example, if you have a net metering plan then any energy that your panels produce but don’t use will be sent back to the grid and you’ll receive a credit for it. This means that you’ll be able to use this energy at night or on cloudy days when your panels aren’t producing as much energy.
  • Upgrades around the house: Upgrading your home to make it more energy efficient can also help improve the efficiency of your solar energy system. This might include things like installing energy-efficient appliances, replacing old windows or doors with energy-efficient ones, and adding insulation to your walls and attic.

Look for different ways to make your home more energy efficient to help your house use the energy from your solar panels more efficiently.
  • Solar energy system design: The way your solar energy system is designed will also play a role in its efficiency. For example, if your system is designed to heat your home as well as produce electricity then it won’t be as efficient as a system that is only designed for electricity production.
  • Average sun exposure: The average amount of sun exposure your home receives will also affect the efficiency of your system. If you live in an area with more sun then your system will be more efficient than if you live in an area with less sun. Read more on Solar Power Information website.

These factors will help you determine how efficiently your solar panels can produce energy for your home.

Long-term Factors That Affect Solar Panel Efficiency

The efficiency of your solar panels can also be affected by the way you use and maintain them. Here are a some of long-term factors that can affect their efficiency:

  • Regular cleaning and maintenance: Just like any other type of energy system, solar panels need to be regularly cleaned and maintained in order to function at their best. This includes things like removing debris from the surface of the panels and making sure that all connections are secure. You can contact a roofing company and have them help you with this if you consider going up on the roof yourself too risky or lack the equipment to do so safely.
  • Proper storage: If you live in an area where it gets cold in the winter, it’s important to store your solar panels properly during those months. This means keeping them clean and free of snow and ice, and making sure that they’re not damaged by the cold weather.
