What Size Solar Panel Do You Need for a Shed?

It’s not a question of if you need to supply electricity to your shed but a matter of what source of energy and how much of it you need. In this case, solar energy is the chosen source, and solar panels are the tools that help get this process started.

However, things aren’t that straightforward. You still need to evaluate just how much your shed needs and the size of panels that can deliver the required amount of power.

It’s not guesswork, but it doesn’t have to be hard either, as you can run through this brief guide on what you need to look out for when choosing the right size of solar panels for sheds.

Picking the Right Solar Panels for Your Sheds

It’s quite remarkable to have reached the stage where there are now solar panels for sheds. So, if you already have a solar panel system, you can wire the shed to your main panel and start the supply. But just how many panels do you think you’ll need to make this feasible and sustainable?

Moreover, it’s not so easy to get a solar panel system up and running in your backyard due to various factors. For example, if you plan to install a rooftop solar panel system to power your shed, you may need to acquire the right permit from the relevant authorities.

Moving on, you also need to evaluate the power consumption of the shed and what type of panels will be suitable for such a task. On the bright side, you only need to assess energy usage and cost of solar panels when evaluating how many panels your shed needs.

Time to dive into it

Evaluating the Power Needs of the Shed

This factor right here is the major determinant when it comes to choosing the right size of panels. The amount of power your shed will need to run smoothly is directly proportional to the size of the panels that you’ll need.

For instance, if your shed is running low on energy consumption, such that you only need energy for lighting and power appliances, a solar panel kit of a small size would be reasonable. Take things up a notch, and that’s when they become interesting.

On the other hand, a larger shed with bigger tasks and more serious care can’t be simply evaluated that way. But that’s by the way.

Another way to understand this aspect is to adopt a practical scenario. Remember that you’re looking at the energy consumption and power a device needs to remain on. So, if you run a shed that requires up to 600 watts of consumable power, you’re immediately looking for a cheap and portable solar panel kit.

But when the activities being run in the shed become more energy-consuming, bigger solar panel systems like rooftop systems become the go-to for powering the shed. So when you pay close attention, you realise that the size of panels will only be big when you have an increase in the activities under the shed.


It’s easy to see why people are switching from conventional energy supply to eco-friendly power sources. They’re green, noiseless, renewable, and tailored towards making life easier for everyone.
