Can you install solar panels in a garden?

Yes, you have the option to set up solar panels in your garden. Moreover, as long as the solar panel system you install does not exceed nine square meters (9m²) in size, there’s normally no need for planning permission.

Garden solar panels encompass a range of configurations, and not all of them necessitate professional installation.

For spacious gardens, ground-mounted solar panels (solar panels securely anchored in the ground) are a viable choice.

On the other hand, if garden space is limited, you can consider smaller alternatives such as portable solar panels or even miniature solar panels designed to power garden lights— all of which you can easily assemble on your own.

Types of garden solar panels

A diverse array of garden solar panels is available in the UK, ranging from sizable ground-mounted solar panel systems to compact solar-powered garden setups. To help you determine which option may be most suitable for your specific needs, I have outlined the various types of garden solar panels below.

Ground-mounted solar panels

Ground-mounted solar panels, also known as standalone solar panels, are essentially the same type of solar panels you would typically install on your roof. However, as the name implies, ground-mounted solar panels are securely anchored into the ground using either a metal frame or a pole.

A single ground-mounted solar panel typically occupies approximately 2 square meters (2m2). However, it’s essential to position it at least 5 meters (5m) or 16.5 feet away from your house to ensure it remains free from any shading caused by the shadow of your house.

For a reasonably sized garden measuring around 15-20 square meters (15-20m2), you should have ample garden space for approximately one to three ground-mounted panels. By way of comparison, powering a 3-bedroom house would necessitate around 10 ground-mounted solar panels, requiring a large garden area of at least 50 square meters (50m2).

If you have an open area along a fence, you might also consider the possibility of installing solar panel fences.

Portable solar panels

Portable solar panels are small, compact, plug-in solar panels specifically designed to power smaller electrical devices like smartphones, laptops, or fans.

While they are commonly used for outdoor activities such as camping or caravanning, there’s no reason why you couldn’t set them up in your garden. Consequently, they are typically smaller in size compared to standard solar panels, with an average output ranging from 100 watts (W) to 200W, which is smaller than the output of a standard solar panel (250kW – 400kW).

Portable solar panels typically require the use of a solar generator, which combines a solar inverter, charge controller, and a solar battery. These components are essential for the safe operation of electrical devices powered by the portable panels.

Solar generators are often available as part of a complete portable solar panel kit, but they can also be purchased separately.

Solar-powered lighting

Unlike conventional garden lights, solar-powered lighting eliminates the need for disposable batteries or an outside electrical connection since it draws its power from the sun. Solar lighting is available in various designs similar to traditional garden lighting, including string lights, lanterns, spike lights, and lamp posts.

These garden lights are equipped with rechargeable batteries, an on/off switch, and miniature solar panels, typically positioned on top of the lamp or ornament, or at the end of the string of lights or lanterns.

During daylight hours, the solar panels generate electricity and store it in the batteries. Once darkness falls, the energy stored in the batteries is harnessed to illuminate the LED light that then lights up your garden.

Solar-powered water features

Solar-powered water features are ornamental garden decorations that include running water elements, such as miniature fountains, waterfalls or birdbaths.

Similar to solar-powered lights, these water features are equipped with compact solar panels and an on/off switch. However, the majority of them do not incorporate rechargeable battery storage since their design focuses on daytime operation when sunlight is abundant.

These garden water features operate continuously as long as they are exposed to sunlight, and high-quality models can even function on overcast or cloudy days.

How much do garden solar panels cost?

The expense associated with garden solar panels varies based on the specific type you select.

Ground-mounted solar panels represent the costliest choice. For instance, a solar PV system comprising ten solar panels, sufficient to provide power for a typical 3-bedroom house, entails an approximate cost of £10,000, including both purchase and installation.

Refer to the estimated table below for a breakdown of ground-mounted solar panel costs, which fluctuate in accordance with the property’s size.

House sizeNumber of solar panelsCost (including installation)System size
Two-bedroom House6£8,00012-18 m²
Three-bedroom House10£10,00020-25 m²
Four-bedroom House14£14,00030-35 m²
Five-bedroom House16£16,00035-40 m²

This table provides an overview of estimated average prices for residential solar panel installations. However, it’s important to note that ground-mounted systems can be about 25% to 35% more expensive than roof-mounted systems.

This increased cost is primarily due to the extended installation time associated with ground-mounted solar panels. Installing them entails tasks such as excavating the ground for wiring connections to your house, which adds to the overall expense.

In contrast, portable or miniature garden solar panels are significantly more budget-friendly than mounted solar PV systems, owing to their smaller scale and the fact that they do not require professional installation from an MCS Certified installer.

Small portable solar panels typically range in price from £120 to £500 per solar panel, depending on their size. Solar-powered lighting options vary in cost, with small fairy lights starting at around £20 and larger setups like lamp posts reaching approximately £150.

Solar-powered water features have a price range, with small decorative ornaments starting at about £80 and larger fountains, waterfalls or birdbaths going up to approximately £400.

Is your garden suitable for solar panels?

To make a garden suitable for solar panels, it should ideally receive a minimum of four hours of direct sunlight each day. Gardens that are shaded by trees or surrounded by buildings may not be the optimal choice for garden solar panels.

In the case of large ground-mounted solar panels, it’s also crucial to ensure that you have adequate space available. As mentioned earlier, a ground-mounted solar panel system capable of powering a 3-bedroom house necessitates a minimum of 50 square meters (50m2) of space.

It’s worth noting that ground-mounted solar panel installations exceeding 9 square meters (9m2) may require planning permission, with additional restrictions in place if your property is located within a conservation area. It’s advisable to thoroughly review all regulations on your local councils planning portal in advance.

However, for smaller setups involving portable solar panels, solar-powered lighting, or solar powered water features, the primary consideration is finding a spot in your garden that consistently receives uninterrupted sunlight, free from shading.


Clearly, there exists a myriad of possibilities for incorporating solar panels into your garden. Options range from budget-friendly solar lights to substantial ground-mounted solar panel systems capable of powering an entire house.

Regardless of the choice you make, harnessing solar panels offers an excellent opportunity to reduce electricity costs while simultaneously decreasing your carbon footprint.
