A Beginner’s Quick Guide to Home Solar Panels
February 1, 2022
With home solar panels, your roof can be more than just a roof!
The energy produced by the sun is one of nature’s most powerful yet free resources. Thanks to technological advancement, solar panels take advantage of that resource.
This electronic device uses semiconductor technology to convert energy from sunlight into electricity. Also known as solar modules, solar panels can power your household.
Further, there are three key benefits of home solar panels. You can use these influencing factors to your advantage.
But will a solar-powered home actually pay off in your case? And if you are planning to invest in one, you want to make sure you are purchasing the suitable unit for your home needs.
There are lots of things to consider, but reading our guide can be a great starting point.
The Basics of Solar Panels
Solar energy begins with the sun, and sunlight plays a big role in solar production. This is where solar panels take advantage of it.
Solar panels are a component of a photovoltaic system. They are constructed from a series of photovoltaic cells arranged into a panel, hence the name.
The light from the sun is composed of energy particles called photons. As the photos hit a solar cell, they knock electrons loose from their atoms.
When electrons zip through the circuit, the movement produces an electric current. And these photons are then converted by the solar panels into electricity.
What are solar panels made of?
The main component of a solar panel is the solar cell. Solar cells are made of semiconductors, such as silicon. They absorb the sunlight and convert it into electricity.
They are connected electrically and packed together in a frame called a solar panel. When you connect multiple solar panels together, they form a solar array. The addition of cabling, brackets, inverter, and so on completes the solar panel system.
Moreover, solar cells are bundled together to form larger units called solar modules, which are paired with solar panels. These modules feature a black or blue-tinted slab that you normally see on a house roof.
Most solar panels are made from crystalline silicon type solar cells. These panels are composed of layers of silicon, including phosphorus and boron.
These cells are in a grid pattern. The number of cells depends on the panel size. There is a variety of sizing available.
Once the cells are set out, the panel itself is sealed to protect them within. For extra protection, the cells are also covered with non-reflective glass.
This glass ensures the sunlight can still reach the cells without any damage from the sun. Once sealed, the panel is placed into a rigid metallic frame.
The frame is designed to prevent deformation. Additionally, the back of the panel is also sealed to avoid damage.
It also includes a drainage hole to prevent water from building up. Otherwise, this could reduce the efficiency of the panel.
Contrary to popular belief, solar panels do well in the heat. Although they work directly with the sun, does the weather affect their efficiency? Find out the answer here.
What Are Home Solar Panels?
Solar panels for homes usually go on the roof. Solar arrays are installed on your roof to generate electricity from the sun.
Home solar panels work by converting light energy to usable electricity. This converted energy is what you can use to power your home, such as appliances. In return, you can save money over time on electricity costs.
The key benefits
- Clean electricity all year round. Solar panels generate clean, emission-free electricity to power your home throughout the year. They can last for more than 25 years, making them an excellent long-term investment.
- Increase your home value. Research indicates that the more solar panels there are on the roof, the higher the home’s value. The estimated increase is almost $6000 dollars per kilowatt of solar energy.
Reduce your carbon footprint. Solar energy is a natural, renewable source. It produces little or no emissions when it is converted to electricity. Plus, it can be replenished, unlike finite fossil fuels. With solar panels, you can lower your carbon footprint.
Furthermore, solar energy can be used for diverse purposes. One, it can produce electricity in areas without access to the energy grid. This also includes power satellites in space or distilling water in regions with limited water supply.
When it comes to maintenance, solar panels do not require much. As long as they are relatively clean, they are good to go.
