If you don’t have a roof suitable for solar panels, a great alternative that can still allow you access to solar is to build a solar pergola, gazebo, or patio cover.
Typically placed on your outdoor patio or backyard area, these structures are a practical and aesthetic way to reap the benefits of solar, without having to place panels on your roof.
Does this type of solar project make sense for your home? Read on to find out.
What are solar pergolas, solar gazebos, and solar patio covers?
They all refer to solar-energy-producing structures built on your outdoor patio or backyard. They can be built upon existing structures on your property, or be custom-built with solar energy production in mind.
You could use a small structure if you’re just looking for enough energy to power outdoor lighting. But with a bigger setup, you could place enough solar panels for a 5 kW solar system or even a 10 kW solar system. A system of that size is usually enough to power your house as well as sell excess electricity back to the grid.
Are solar lights and solar umbrellas different from solar pergolas, solar gazebos, and solar patio covers?
Yes, they are.
You have probably seen solar lights and solar umbrellas, which are popular in people’s backyards these days.
Solar lights are smaller devices that use solar cells, which are either built-in or attached as a small accompanying unit. The cells charge an internal battery during the day and then power lights at night. There are many different types: solar path lights, solar spotlights, solar ambient lights, etc.
Solar umbrellas, meanwhile, are patio umbrellas with inbuilt solar cells that power attached lights and sometimes even a USB charging station.
Solar lights and solar umbrellas have limited power-producing capacity are not built-up structures like solar pergolas, gazebos and patio covers.
Which is better? Rooftop solar vs. solar pergolas, gazebos and patio covers
For most houses, the rooftop is the place with maximum surface area and highest exposure to the sun. It is usually also convenient to mount solar panels there, as minimal construction or modification is required. These factors are why roof-mounted solar panels have remained the most popular option for homeowners.
However, in many instances, your roof might not the right place to put your panels. Here are some of them:
- Space constraints: Your roof does not have space for the number of solar panels your require. (Not what this figure is? Calculate the sq. ft. required for solar panels here).
- Shade: Obstructions like surrounding buildings or trees might block direct sunlight from hitting your roof.
- Unfavorable angle or positioning: You will not produce maximum power unless your roof faces south. The roof angle, or pitch, also needs to be at the right level (30 to 45 degrees) to work best.
- Aesthetics: Maybe you just don’t like the way they’d look on top of your house...
Ground-mounted solar panels are one alternative to consider. But they have one big disadvantage: they require substantial amounts of real estate, space that you can’t use for anything else.
This is where the solar pergola, solar gazebo or solar patio cover—as well as the solar carport— enter the picture. They are all dual-use structures, so they’re more space efficient than a ground-mounted setup. You might already have one of these structures out back, which you might easily be able to adapt or modify to hold solar panels.
Otherwise, if you are building one of these structures from ground-up, you can go for a designed-for-purpose structure that looks looks great and is optimized for maximum solar energy production. Of course, opting for a whole new structure means adding construction costs to the cost of solar panels.
Wrapping up
Solar pergolas, gazebos, and patio covers are just one of the routes you can take to go solar. If you can’t or don’t want to put solar panels on your roof, you could use them in order to gain all the benefits from going solar.
To see if they’re right for you, find a local solar installer who can assess your property and provide recommendations.
