How Do Solar Panels Perform Nowadays
We all know solar energy is much cheaper compared to other types of energy. That’s why so many homeowners are interested in getting solar panels installed in their houses.
Solar panels have become an alternative energy solution. It’s important to note that the popularity of solar panels in the US and other countries around the world is constantly growing.
A question most homeowners have pondered in regards to solar is how will the panels perform nowadays. More importantly, how will they work for you at your specific location? This is something that can be known provided your system is designed with the affecting variables in mind.
Today, we’ll talk about the performance and efficiency of solar panels. First, we’ll explain how solar panels work. Then, we’ll dig deeper into the factors that affect the efficiency of solar panels. Lastly, we’ll give you insights into maximizing a solar panel’s efficiency.
So, let’s get started.
How Do Solar Panels Work for Your Home
First of all, you need to get an understanding of solar panel technology. In other words, you should know how solar panels work and how they generate electricity for a house.
A standard solar array consists of the following components:
As you probably know, the main goal of a solar array is to convert sunlight into electricity. This process consists of three steps:
- Absorbing incoming energy
- Generating electrical current
- Distributing electrical power
Absorbing incoming energy. Initially, a solar panel absorbs sunlight. Solar radiation is absorbed by photovoltaic solar cells. Sun rays interact with the silicon cell on a solar panel and electrons start moving. As a result, the flow of electric current is created. This is how the sun’s energy is converted into the so-called direct current (DC) electricity. However, DC electricity can’t be used by home appliances.
Generating electrical current. At the next stage, DC energy is converted into usable alternating current (AC) energy via an inverter. The reality is, the vast majority of home appliances are powered by AC energy.
It’s important to note that the inverter technology is used to convert DC energy from solar panels into AC energy because the inverter is essentially the heart of the system.
Distributing electrical power. Lastly, alternating (AC) current is distributed by wires from the so-called solar inverter that’s mounted on the side of your home. As a result, AC energy is delivered to your house through an electrical panel and distributed in your living environment. Now, electronic devices in your living environment can be powered by electricity that’s generated by solar panels.
Factors that Affect the Solar Power Production Efficiency
It’s worth noting that solar panels perform differently. The efficiency of the modern solar panels ranges between 15% – 22%.
It’s important to know that the performance of solar panels depends on a variety of factors. The big question is – which are the factors that affect solar panel’s efficiency?
Now, it’s time to get the answer!
Key variables that often affect the production are:
- sun intensity
- heat buildup
- weather conditions
This list could go on and on. Solar panels allow people to save more money and energy on electricity. However, every homeowner should aim to maximize their solar panel’s efficiency.
Luckily, it’s possible to improve the efficiency of a solar panel. Below, we’ll explain how to make use of modern technologies to get the most of a solar power system and achieve the best possible results.
Maximizing Solar Panel’s Efficiency
365 Solar Energy uses a design program that takes weather data from the nearest airport into consideration to help predict the number of cloudy days, rain, and snow traditionally seen in the area. This is important because of the number of clouds and the temperature can both drastically affect your system’s production.
Next, 365 Solar Energy does a shade analysis of the desired location of the solar panels. They use a CAD (Computer-Aided Design) tool to map out the amount of shade caused by surrounding structures and trees. They then factor the effects of the shade into their production proposal as it can affect the production numbers.
365 Solar Energy knows not every day is going to be perfectly sunny, and chooses their production equipment accordingly. They use Tier 1 American made 320 Watt monocrystalline panels to maximize the amount of sunlight that is available to capture. Then they optimize the panels to allow each panel to function at a peak performance level.
Finally, the power travels to a Solaredge inverter where the power is converted from DC power to AC power. The power then runs into the home allowing the excess power to back feed to the grid; which shows up on the power bill in the form of credit.
