Rooftop Solar Panels

It entails installing solar panels on the shed’s roof, running cables to an inverter, having outlets for plugging things in, and generating power for lighting.

Make sure that you have high capacity battery system to maximize solar energy in the evenings and on cloudy days when you probably need more power for lighting and warmth.

Merits of Using a Solar Panel for Your Shed

  • The system has a cheap cost of operations. As the sun provides free energy, once the solar panels have been installed and all the connections have been made, they will be free to use.
  • It is eco-friendly meaning it is good for the environment.
  • You will find it is easy to set up.
  • It will indeed be a profitable investment for you.
  • Helps to reduce your energy bill costs.

Demerits of Using Solar Panels for Sheds

  • Its initial setup can be expensive considering the type of solar panels you will use.
  • To support the additional weight of the solar panels, your shed must be sturdy enough.
  • It does not always generate enough energy.
  • The structure must be large enough to accommodate the inverter.

What Are the Adequate Solar Panel Sizes Needed for a Shed?

Solar Panel Sizes

The size of panels varies based on individual preferences. In terms of power usage and solar exposure, it will primarily depend on how you want to utilize your solar panels for sheds.

A modest 50W panel and simple battery configuration may be sufficient for essential needs such as lighting and charging smaller gadgets.

If you require a lot of power or have limited access to light, you should go for bigger solar panels and additional batteries. That will gradually increase your power supply.

Examples of the Energy Requirements for Various Equipment

Let’s now have a look at the total amount of electricity required by different devices simultaneously. Calculate the power you need from solar panels for sheds from the below table.

Device  Electricity Required
Mobile Phone Charger 5W
Desk Light 50W
Computer 50W
Desktop Computer (17-inch Display) 400W
Power Drill 500W
Commercial Printer 800W
Jigsaw Power Tool 900W
Saw, Circular 3,000W
Oven Electric 5,000W

When utilizing an inverter, it is standard practice to use one that adds 20 to 50% extra power than the minimum quantity needed. Additionally, it should be able to provide more than twice the power needed by the item with the highest power consumption.

Consider how many of the following you’ll have active at any given time to determine the right solar panels for you.

What Size of Roof Space Do I Require for the Solar Panels?

More solar panels for sheds can be installed on bigger roof spaces which can ultimately increase electricity output. You might, therefore, be restricted to a particular number of panels for smaller sheds.


You’ll require 16, 250W solar panels for a typical 4kW household setup. It results in a total area that is a little over 25 meters square which is sufficient for a 3-bedroom family.

Almost all sheds will be much smaller and take up far less room in reality. A 4kW installation requires more than 25, a 3kW arrangement more than 20, a 2kW installation just over 12, and a 1kW installation more than 8, all in terms of square meters.

You have the chance to reduce the size of your options considering the limitations of the available roof space. If you want more power, go for a larger shed if you’re still deciding on it.

Things to Consider When Installing Solar Panels for Sheds

  • Inverter

The amount of electricity that can be generated from solar panels depends on the size of the inverter. You must determine the size of the inverter needed depending on the items that will be in use.

For example; A 900W jigsaw may be operated for around two hours by a 2,000-watt solar arrangement

  • Cables

Electrical wires/cables will be needed to connect the installations. You will need to use Cables to feed DC electricity from the solar panels to the inverter.

  • Battery

A deep cycle 12V DC battery, which resembles a car battery, is typically used to store energy. Depending on the amount of power you wish to store and make available to you, you can add more as necessary.

  • Charge Regulator

It controls how much energy the battery receives from the solar panels for sheds. Its main purpose is to prevent the battery from becoming overcharged or empty.

Additionally, it measures the temperature and turns off the power if the battery is at risk of overheating. These features make sure that the battery life lasts longer.


We have tried to discuss several aspects of solar panels for sheds to help you make your decision. Make sure that you go through every section and go for the type of solar panels you require.
