Off-Grid Solar Panel Systems: Our Independent Guide and Expert Advice
What is ‘off-grid living’?
Living ‘off-grid’ means to live independently of traditional utility infrastructure – e.g. away from water, gas and electricity supplied by regional or national providers. If you live off-grid, you need to grow your own food and manage your own water supply.
You’ll also need to generate your own energy; people living away from traditional infrastructure will often use an off-grid solar panel system. It’s a niche lifestyle choice that can be challenging, but in 2023 there were an estimated 150,000 homes off-grid in the UK – so it is possible, with the right planning and investment.
Living off-grid in the UK: FAQs
- Why live off-grid?
Many people opt for off-grid living to reduce their environmental impact by generating their own energy through solar panels
- Where can you live off-grid?
Off-grid communities can be found across the UK, but they are more prevalent in rural areas or regions with access to the space required to generate ample electricity through solar panels
- Who chooses to live off-grid?
The demographics of those living off-grid in the UK vary widely. While some are environmental enthusiasts or individuals seeking a simpler lifestyle, others may have chosen this lifestyle due to financial constraints or a desire to disconnect from mainstream societal norms
- How can off-grid living be achieved?
Advances in technology have made off-grid living more feasible and comfortable. Innovations in battery storage systems have made it easier for people to live off-grid without sacrificing modern comforts
- What are the challenges of living off-grid?
Off-grid living in the UK isn’t an easy choice – there are legal restrictions, you need certain types of planning permissions, and there are building regulations in place that may limit certain off-grid practices
How feasible is off-grid living?
Living without connections to the main utility infrastructure (electricity, water, gas) is possible but can present significant challenges that most people’s lives can’t easily accommodate. How feasible it is depends on a number of factors:
- Your location: Remote areas might lack grid access, leading residents to rely on alternative energy sources like solar power, wind turbines, or generators
- Space: How much space you have for installing solar panels will determine how much energy you can produce for your daily needs
- Night-time capacity: You’ll need to consider how much energy you’ll need to store for when the sun goes down and the lights come on
- Technology: Advancements in off-grid technologies, such as solar panels, batteries, and efficient appliances, make it more feasible to live independently off-grid
- Costs: Initial setup costs for off-grid living can be high due to the purchase and installation of alternative energy sources and technology
Below we’ve put together a brief guide to choosing an off-grid solar panel system…
Solar power for off-grid living
Solar power is a clean, renewable energy source that’s perfect for off-grid living.
An off-grid solar panel system converts sunlight into electricity using photovoltaic cells, and the energy generated can be stored in batteries to power homes, lighting, appliances and electrical devices. The advantages of using an off-grid solar panel system are:
- Renewable energy: Sunlight is a virtually unlimited resource, making it a sustainable and renewable energy source for converting into electricity
- Independence: Off-grid living with solar panels gives you independence from centralised utility services, reducing reliance on fossil fuels and minimising the impact on the environment
- Cost savings: While the initial investment for solar panels can be significant, they offer long-term savings by eliminating monthly utility bills
- Environmental benefits: Solar energy production produces no greenhouse gases, contributing to a cleaner environment and combating climate change
- Reliability: With proper installation and maintenance, solar panels can provide a reliable source of energy even in remote locations, as long as there is sufficient sunlight
- Versatility: Solar panels come in various sizes and types, allowing flexibility in design and installation to meet different energy needs
It’s important to bear the following factors in mind when considering an off-grid solar panel system:
- Initial costs: The upfront cost of purchasing and installing solar panels and battery systems can be substantial, though it tends to pay off over time through energy savings
- Weather dependence: Solar panels rely on sunlight, so their efficiency is affected by weather conditions
- Capacity: Solar panels and batteries have limited capacity, which can be affected by sunlight availability and energy usage. So, if you run out of power, you have no way of getting more until the sun comes out again
- Maintenance: Regular maintenance is necessary to ensure optimal performance and longevity of the solar panel system
The different types of off-grid solar panel system
Monocrystalline solar panels:
- Performance: Good performance in low-light conditions
- Efficiency: High efficiency, making them space efficient too
- Cost: Relatively inexpensive and readily available
Durability: Long lifespan and typically have extended warranties
Polycrystalline solar panels
- Performance: Good, but with lower performance in high temperatures
- Efficiency: Slightly lower efficiency compared to monocrystalline panels
- Cost: Cheaper than monocrystalline panels
Durability: Shorter lifespan than other panels
Thin-film solar panels
- Efficiency: Lower efficiency compared to crystalline panels
- Cost: Generally, more affordable than other panels but they do require more space
- Flexibility: Lightweight, flexible, and can be integrated into various surfaces
Bifacial solar panels
- Performance: Dependent on proper installation and reflective surfaces underneath
- Efficiency: They capture light on both sides, potentially increasing overall energy output
- Cost: Similar to monocrystalline panels in price
CIGS (Copper Indium Gallium Selenide) solar panels
- Efficiency: Moderate efficiency and good performance in low-light conditions
- Durability: Generally, less durable than crystalline panels
Perovskite solar cells
- Efficiency: Rapidly improving efficiency rates, potentially surpassing traditional panels
- Cost: Promising as a low-cost alternative though currently still in developmental stages
- Cost: The next step in solar technology but not commercially available yet
Other factors to consider for your off-grid solar panel system
- Battery storage: Essential for storing excess energy generated during the day for use at night or during cloudy days
- Backup generator: In some cases, having a backup generator (typically running on propane or gasoline) can supplement solar power during extended periods of low sunlight
- System sizing: Ensure your system is appropriately sized to meet your energy needs. Factors include location, weather patterns, household energy usage, and panel efficiency
Each system has its pros and cons, and the system you choose will depend on factors like budget, available space, energy requirements, and environmental conditions.
While it’s feasible for some individuals and communities to live off-grid, for most people in urban or suburban areas, it can be difficult due to the infrastructure, lifestyle preferences, and convenience associated with grid-connected services. However, advancements in technology and a growing interest in sustainable living are allowing homeowners to get closer to off-grid living and some of the benefits this brings – but without the need to be completely disconnected.
