How To Install Solar Panels On Shed

Solar Panels for Sheds: What You Need to Know

Published: 03/08/2021

Solar panels for sheds are becoming increasingly popular. And that'south understandable when you consider how economical and eco-friendly they are. That said, they still provide an electric supply – and that's why you must make sure you exercise everything correct. Every bit we land in our post on how to supply electricity to a garden shed, electricity can be unsafe, and then information technology's important to stay safe during both installation and employ. Are you looking for a convenient and price-friendly mode to power your summerhouse lighting? Perhaps you want to know whether it's worth putting solar panels on your shed at all. Or maybe you just want to know how many watts y'all need for a solar-powered shed in the United kingdom of great britain and northern ireland. In this mail service, nosotros aim to answer these questions…

The pros and cons of solar panels on sheds

Earlier installing any kind of solar energy in your shed (or log cabin or summerhouse) in the U.k., you need to weigh upwardly the pros and cons:

Pros

• Reduces operating costs
• Good return on investment
• Eco-friendly
• Gives you some control over your energy bills
• You could make coin from your surplus free energy

Cons

• Expensive initial investment
• Your shed must stiff enough to take the extra weight (solar panels)
• The building needs to large enough to house the inverter
• The panels need to face south, eastward or west (ideally south)

Every bit y'all can run across, there are several attractive potential benefits to installing solar power in your shed – not least the fact that it could save (and even make) y'all coin. Only obviously, this comes with a sizeable investment, so yous must consider you lot think information technology's worth your fourth dimension, effort, and initial toll. Fortunately, solar panels are available in different sizes, so that could help reduce some of the initial costs – although you need to brand sure whichever method you utilize provides enough electricity for your needs (more virtually this later).

Is it worth putting solar panels on my shed?

While information technology's clear past now that yous tin power a shed with solar panels in the UK, the question of whether it's worth doing and then is a legitimate one. Here are some of the factors you need to consider:

• What you utilise your shed for
• How much power you need
• The size and age of the shed
• The force of the roof
• The position of the edifice
• Your budget

In terms of how you employ – or intend to utilise – your shed, if you lot spend lots of time in there and need electricity to ability lights, appliances, gym shed, or garden office equipment, then solar panels could exist a coin-saving (and eco-friendly) alternative to mains power. Specially if you demand solar panels for shed heating or summerhouse lighting (for example). Likewise, the corporeality of solar free energy you need will depend on how you use the shed (more near this in the next section). The decision as to whether it's worth putting solar panels on your shed will also depend on the forcefulness and age of your garden edifice. For example, if you have an old shed with a weak or sunken roof, there's no indicate in adding solar panels – unless, of course, yous buy a new shed (or another blazon of garden building).

Can I put solar panels on my shed roof in the UK?

This may seem like a ridiculous question considering this postal service is near solar panels for sheds; we've already established that it's legal to put your solar panels on your shed roof in the Great britain. But y'all need to make sure your shed roof is strong plenty - solar shed construction is all-of import. In other words, you shouldn't just purchase whatever new shed. To be able to hold up the solar panels, the building should be made from materials that are unlikely to buckle under the weight. With this in heed, nosotros don't recommend trying to add together solar panels to a cheap shed fabricated from flimsy OSB lath – information technology just won't final!

Understanding solar panels for sheds

In this section, nosotros take you through all the devices (and their associated terms) and how they work.

How exercise solar panels work?

Solar panels comprise photovoltaic (PV) cells, which absorb sunlight and catechumen it into direct current (DC). The DC and then passes through an inverter (within the shed) and converts into alternating current (Air conditioning), which is then used to ability your shed. At present you know how solar panels power your shed, permit's look at the central devices you need to know about:

AC outlet

Used with smaller systems. This connects to the battery and is used to power small appliances. – such as a laptop or smartphone.

Battery

It may seem foreign that a solar-powered shed would require a bombardment. Surely, the solar panels are the power source, right? Well, yes and no. While solar panels generate the power (with the help of the inverter and cables), the bombardment stores the energy for later on use. Specifically, solar units need a deep cycle battery, which is otherwise known every bit a deep discharge battery.

Cables

The cables feed the DC current from the solar panels to the inverter. To ensure maximum efficiency and safe, you lot must make sure the cables y'all utilize take the right rating for your system. To work this out, use the DC Cable Sizing Tool at solar-air current.co.u.k. [1].

Charge controller

Regulates the ability coming from the panel and stops the battery from overcharging (or running completely flat). The charge controller also features a temperature sensor – the controller will shut off the system if the ambient temperature gets also hot. This, in plow, helps boost (and maintain) the efficiency of the battery.

Inverter

The inverter converts the direct current (DC) power (generated past the solar panels) into alternating current (AC). Alternate current is the standard type of electricity required to power electrical circuits in the United kingdom.

How many watts practice you need for a solar-powered shed in the UK?

Again, the amount of electric devices you use will determine the corporeality of power yous need, which, in turn, will decide the size of the panels yous require – and therefore how much it will cost. Photonicuniverse.com provides a chart that matches the amount of power (watts) typical pieces of equipment will utilize and matches information technology to the continuous power rating of the inverter. Here are some typical ratings for types of equipment you may need in your solar-powered shed (according to Photonic Universe) [two]: Mobile phone charger: 5W Halogen light: 100W Desk lamp: 50W Desktop reckoner (with 17" monitor): 400w Commercial printer: 800w Laptop: 50w 42" LCD TV: 200W Electric oven: 5000W Obviously, you may non need to apply all the equipment listed above in your shed; these are just examples you might use in your human cave shed, live-in shed, or garden function. Armed with this information, you tin so work out how powerful your solar power shed kit needs to be. For example, if y'all desire to use a laptop (50W), a mobile phone charger (5W) and a desk-bound lamp (50W), you demand 105W of total power – but wait! To ensure y'all have the all-time solar panel kit for your UK shed, we recommend using an inverter that provides both 20-fifty% more than than the minimum total power you need AND more than than twice the amount of power of the most power-hungry piece of equipment. With this in mind, nosotros would recommend a 160W system for this purpose (solar panel kits in the UK tend to have round-numbered ability ratings). By ensuring you take more than enough ability bachelor to ability all your equipment, yous'll boost efficiency and help forbid faults occurring in the solar panels on your shed.

What size solar panel exercise I need for my shed?

The size of each solar console y'all need depends on what you lot desire to achieve. If yous have an boilerplate-sized shed or log motel, a single 50-watt panel solar kit may be enough. But if you desire underfloor heating - which would be a existent luxury for any shed - y'all're probable to need at least three 150W solar panels.

Solar panels for sheds: how much roof space do you demand?

However, you lot should carry in mind that if you wish to live in your garden building, you lot'll need adequate shed roof space for all the solar panels y'all'll need. For example, let's say you alive in the garden building and you demand 4kW of power per day – that means yous'll need 16 (sixteen) 250W panels and 25.6m² of space on your roof [3]. This means that something like the Omega log motel would be a more than viable option (for providing plenty ability for a live-in shed) than a building designed as a storage shed, for example.
