Published: 11 Jun 2025 ・ Read time: 8 Mins
If you’re looking to make the most of your outdoor space this summer, why not power up your outdoor buildings with solar energy? With the advancements in solar technology, it's easier and more affordable than ever to harness the power of the sun to run your outdoor offices, sheds, and greenhouses. 
Helping homeowners venture into the exciting world of Renewables, here at City Plumbing we show you how simple and effective it is to power up the outdoors with solar, throughout summer and beyond. With our expert advice and guidance, we explore how you can transform your outdoor spaces into efficient and sustainable areas with the help of solar PV panels.

The Benefits of Solar Energy for Outdoor Spaces

When it comes to outdoor spaces, solar energy offers many benefits. Here are a few reasons why you should consider powering up with solar this summer:
Cost-Effective: While the initial investment in solar panels may seem daunting, they can actually save you money in the long run.
  • Reduced Electricity Bills: This is arguably the most immediate and tangible benefit. Once the initial investment in solar panels is made, the electricity generated from the sun is free. This significantly reduces or even eliminates reliance on the grid for these outbuildings, leading to substantial long-term savings on your electricity bills.
  • Protection Against Rising Energy Prices: The UK has seen volatile energy prices. Generating your own power from solar panels provides a degree of energy independence, shielding you from future price hikes and making your energy costs more predictable.
  • Off-Grid Capability: For sheds and greenhouses, running power cables from your main house can be costly, disruptive (requiring excavation), and complicated. Solar panels offer a clean, independent, off-grid solution, saving you time, money, and hassle on cabling.
  • Smart Export Guarantee (SEG): While not as lucrative as previous Feed-in Tariffs, if your system is connected to the grid (which is possible for larger setups or if you want to export excess power from your main house) you can potentially earn money by selling any surplus electricity back to the grid.
  • Off-Grid Capability: With solar power, you can go off-grid and still enjoy all the modern amenities in your outdoor spaces.
Environmentally Friendly: Solar energy is a clean and renewable source of power, making it a sustainable choice for your outdoor spaces.
  • Reduced Carbon Footprint: Solar energy is a clean, renewable energy source that produces no harmful greenhouse gas emissions during operation. By using solar, you significantly reduce your carbon footprint and contribute to a more sustainable environment.
  • Eco-Friendly Image: For outdoor offices, especially those used for businesses, powering with solar demonstrates a commitment to sustainability, enhancing your brand image and potentially attracting eco-conscious clients and partners.
  • Support for Green Initiatives: Choosing solar aligns with broader UK and global efforts to combat climate change and transition to a low-carbon economy.
Enhanced Functionality and Convenience:
  • Extended Use of Outbuildings: Solar power can transform a basic shed into a fully functional workshop, garden office, or hobby space that can be used comfortably year-round. This means reliable lighting, power for tools, heating/cooling, and even Wi-Fi.
  • Greenhouse Climate Control: For greenhouses, solar power can run essential equipment like ventilation fans (to prevent overheating), heating systems (to extend growing seasons, even in colder UK months), irrigation pumps, and automated monitoring systems. This allows for more consistent temperatures and healthier plant growth, potentially leading to increased yields and the ability to grow a wider variety of plants.
  • Reliable Power: With battery storage, solar systems can provide a reliable power supply even during grid outages, which can be crucial for sensitive equipment in offices or for maintaining optimal conditions in a greenhouse.
  • Flexibility and Scalability: Solar systems are highly scalable. You can start with a smaller setup for basic needs and easily add more panels or battery storage as your energy demands grow or as you invest in more equipment.
  • Easy Installation and Low Maintenance: Solar panels are relatively easy to install, especially on smaller outbuildings where scaffolding might not be required. Once installed, they have minimal operating costs and require very little maintenance, typically just an occasional cleaning.

Powering Up Your Outdoor Office with Solar

If you have an outdoor office where you work or spend time during the summer months, solar energy can be a game-changer. Imagine being able to run your laptop, lights, and other electronic devices without worrying about high electricity bills. Solar panels can easily be installed on the roof of your outdoor office, providing you with a reliable source of power throughout the day.

Transforming Your Shed into a Solar-Powered Space

Your shed doesn't have to be just a storage space, with solar power it can become a functional and energy-efficient area. Whether you use your shed as a workshop, a playroom, or a relaxation spot, solar panels can help you power up lights, tools, and other gadgets without relying on the grid. Plus, solar-powered sheds are environmentally friendly and can add value to your property.

Create a Greener Greenhouse with Solar Energy

For all the green thumbs out there, solar energy can revolutionise the way you operate your greenhouse! By installing solar panels on the roof of your greenhouse, you can power up fans, heaters, and irrigation systems, creating the ideal environment for your plants to thrive. Solar-powered greenhouses are not only cost-effective but also sustainable, allowing you to grow your produce with minimal impact on the environment.

How To Choose The Best Solar Panels For Outdoor Buildings

Choosing the best solar panels for outdoor buildings like sheds, offices, and greenhouses in the UK depends on your specific energy needs, available space, budget, and the type of building. Here's a breakdown of key considerations and popular options:
1. Select the Right Types of Solar Panels
  • Monocrystalline Panels:
Most efficient (15-20%), best for limited space, performs well in low light conditions (common in the UK), typically has longer warranties (25 years). Generally recommended for sheds and garden offices where space is at a premium and you want to maximise power output.
  • Polycrystalline Panels:
Less expensive, easier to manufacture, performs relatively well in higher temperatures. A good budget-friendly option if you have ample roof space and don't need the absolute highest efficiency.
  • Flexible Solar Panels:
Lightweight, can be used on less sturdy roofs or irregular surfaces (like some sheds or campervans), cheaper than rigid panels, easy for DIY installation. Flexible solar panels are ideal for smaller, less robust structures where weight is a concern or for portable applications.
  • Transparent Solar Panels:
Emerging technology, can replace windows while generating electricity, potential for dual purpose (light and power) Niche application, potentially for greenhouses where light transmission is crucial.

2. Determine Your Power Needs

Before buying solar panels, assess what you want to power:
  • Basic Lighting & Device Charging: A 120W-160W panel kit might suffice for LED lights, phone chargers, and security cameras.
  • Small Appliances & Tools: For laptops, small power tools (drills, saws), and mini-fridges, you'll likely need 400W kits and above.
  • Larger Offices/Workshops/Greenhouses: Running multiple power tools, TVs, or heating systems will require a larger system, potentially 1kW to 3kW or more, often with several panels. Greenhouses with heating can be particularly energy-intensive, requiring 8-20 panels for off-grid solutions.

3. Decide Between Solar Panel Kits vs. Individual Components

  • Solar Kits: Ready-to-install kits include panels, charge controllers (to manage battery charging), batteries, inverters (to convert DC to AC power for standard appliances), and all necessary cables and connectors. These are generally easier for DIY installation.
  • Individual Components: If you have specific needs or want to customise your system, you can buy components separately.

4. Ensure The Key Components For An Off-Grid System

For most outdoor buildings not connected to the main grid, you'll need an off-grid system:
  • Solar Panels: To convert sunlight into electricity.
  • Charge Controller: Regulates the voltage and current from the solar panels to the battery, preventing overcharging. MPPT (Maximum Power Point Tracking) controllers are more efficient.
  • Battery/Batteries: To store excess energy generated during the day for use at night or on cloudy days. Lithium batteries are popular for their longevity and performance.
  • Inverter (if powering AC appliances): Converts the DC power from the battery into AC power that standard UK appliances use.

5. Understand Installation Requirements

  • Roof Strength: Ensure your building's roof can support the weight of the panels. Flexible panels are an option for less robust structures.
  • Orientation & Angle: Panels work best when facing south and angled at 35-40 degrees from horizontal to maximise sunlight absorption.
  • Shading: Avoid any shading from trees or other buildings, as even partial shading can significantly reduce efficiency.
  • Permitted Development Rights: UK solar panels on outbuildings within your property generally fall under "permitted development rights" and may not require planning permission, as long as they minimise impact on the building's external appearance. However, it's always wise to check with your local authority.
