The pros and cons of solar power on sheds

Most shed conversions use solar energy to generate power for their off-grid shed. Although they are costly upfront you can expect a long-lasting solution to your power woes. 

If you decide to go ahead with solar panels it is worth bearing in mind there are pros and cons to solar power and it is important to consider the following: 

Pros of solar panels 

Cons of solar energy 

Is it legal to have solar panels on a shed roof in the UK? 

With the UK having so many rules and regulations around building work, you may be wondering whether you are allowed to put solar panels on your shed roof. However, there is no need to worry about this as you are legally allowed to put solar panels on a shed roof. Alongside this, no permission is required from the council to do this. 

Understanding how much power you need for your shed

Before you get started with sourcing power for your off-grid shed, it is important to familiarise yourself with the equipment required. If you are looking to power lights and a game console, this will require a lot less power than a shed that is running a fridge and has a home theatre system. 

To understand how much power your appliances use, Photonic Universe has an easy-to-use guide that rates the power of your home appliances. 

For example, a laptop requires only 50w of power, a 20” colour LCD TV uses 100w and a home theatre system comes in at 500w. If you were to use a home theatre and a small fridge you will require a supply of 1000w.

The reason you need to work this out as accurately as possible is for determining the power rating of your inverter. To ensure you have the best quality of power for your off-grid shed, aim for an inverter that provides 20-50% more than the average you need. 

What equipment do I need for my off-grid shed?

This is the bit where understanding what is required for an off-grid shed is important, as without these key items your off-grid shed may be unable to power correctly. 


The kind that stores energy from solar or wind power. These are known as ‘deep-cycle batteries. The voltage is usually 12V. The more energy required; the more batteries will be needed.


If you are unsure which cables are required for your shed, it is important to seek advice from a qualified electrician. The installation of the wrong wires can cause the circuit to overload, which can be dangerous. Not only could this catch fire, but it is also wasteful. 


A power inverter running off a battery changes DC to AC in order to run household appliances. This is how one routes power to the shed. 

Which power source works best for your off-grid shed

Although a generator may seem like a good idea, it can be noisy, therefore not an ideal solution for your neighbours’ and others living in your home. 

A better solution is wind or solar energy, an eco-friendly option that can save you money in the long run but can also be costly upfront. 


Although it may sound complicated, taking your garden shed off-grid is a straightforward process, especially when you have the correct components to do so. The overall benefits of taking your shed off-grid often outweigh the cons. Therefore if you are looking to go ahead with this we hope you’ve found our step-by-step guide helpful.
