Solar power has become a very common way to generate electricity from renewable energy sources.

Solar panels are becoming cheaper every year, and they can now be installed at home or businesses without breaking the bank.

Before you want to purchase your solar panels, however, you might want to begin by working out how many you can fit on your property.

Today we are going to be helping with that by telling you the average solar panel dimensions. 

Why Do You Need To Know The Size Of Solar Panels? 

The size of your solar panels will depend on what type of system you have. If you’re looking for a simple setup, you may only need one or two panels.

However, if you’re planning to install an entire array of panels, then you’ll need to know the exact number you require. 

This is because each solar panel needs to be connected to other panels in order to create a complete circuit.

To do this, you’ll need to know the size of the usable space on your roof. Usable space includes the areas in which solar panels can be fitted onto properly.

These areas will need to be reached by the sun at least some of the day, otherwise you will be spending money on solar panels for very little energy back. 

Once you have worked out how much usable space you have on your roof, you can determine which size of solar panels you can get to cover your roof.

Solar Panel Dimensions

Residential solar panels will have an average height and width of 65 by 39 inches, otherwise known as 5.4 by 3.25 feet.

Different solar panel dimensions will have slightly varied dimensions, but these are the average that has been around for decades. 

There are several different types of solar panels available on the market today.

Each type offers its own benefits and drawbacks when it comes to installation, so make sure you choose the right kind for your particular situation. 

Most people tend to think about solar panels as being rectangular shaped. They are, but there are also square solar panels available.

Square solar panels are perfect for rooftops where there isn’t enough room for a full-sized rectangle. 

You should also keep in mind that solar panels come in various shapes and sizes. Some are flat, while others are curved.

Flat panels are better suited to roofs that don’t slope too much, whereas curved panels work well for sloped roofs.

It’s important to remember that solar panels aren’t just made up of metal and glass. They’re actually quite heavy. A typical residential solar panel weighs around 40 pounds.

That means that you won’t be able to lift them into place yourself. Instead, you’ll need to hire someone who knows exactly how to handle heavy objects like this. 

If you live in an area that experiences high winds, then you might find that installing solar panels is not possible. In fact, most solar panel manufacturers recommend against placing panels in windy locations.

Installing Your Solar Panels

When it comes to installing solar panels, you’ll need to consider a few things. First of all, you’ll need to decide whether you want to go with a DIY project or pay for professional help.

There are pros and cons to both options, so you’ll need to weigh up the costs and benefits before making any decisions. 

DIY projects are usually cheaper than hiring professionals, but they take longer to set up. You’ll also need to learn how to handle tools such as drills, saws, hammers, screwdrivers, etc. 

It is generally advised that you opt for a professional installation when it comes to solar panels to ensure that they are being attached correctly.

That’s a lot of money for one solar panel that is going to fall off as soon as a light wind touches it! 

Before you install your solar panels, however, you’ll need to determine how many can fit on your roof. Do this by measuring your usable roof dimensions and seeing how many panels you can fit within it.

Then you will have to work out the weight of all of these panels and determine whether your roof can handle that much pressure. 

If you are unsure on how to do this, it’s best to consult a professional. It’s better to spend money getting expert advice than to pay for and install too many solar panels that break your roof.
