With rising energy costs and increasing pressure to adopt sustainable practices, many UK hotel owners are asking, "Can you run a hotel on solar power?" The answer: Yes, running a hotel entirely on solar power is a complex proposition, but it’s increasingly achievable with the right setup. 

This question reflects a growing interest in renewable energy solutions to reduce operational expenses and appeal to eco-conscious travellers. In this article, we’ll discuss the feasibility of powering a hotel with solar energy, the costs involved, potential savings, government incentives, and real-world examples to help you make an informed decision. 

Whether you’re a boutique hotel owner, a facilities manager, or a hospitality investor, our goal is to provide clear, practical insights to guide your investment in solar panels.

Is It Possible to Power a Hotel Entirely with Solar Energy?

Yes, it is possible to power a hotel entirely with solar energy, but it comes with challenges.

While technically feasible, powering a hotel solely with solar energy requires careful planning, significant investment, and optimal site conditions.

According to the Energy Saving Trust, solar photovoltaic (PV) systems can significantly offset a hotel’s energy consumption, particularly when paired with battery storage and energy-efficient practices. 

However, complete off-grid operation is challenging in the UK due to seasonal variations in sunlight, especially in winter when solar output drops by up to 90%. A hybrid system, combining solar panels, battery storage, and a grid connection is often the most practical and cost-effective solution.

Key Factors Affecting Feasibility

  • Hotel Size and Energy Demand: The Carbon Trust estimates that UK hotels consume an average of 394 kWh per square metre annually, far higher than most commercial buildings. Smaller boutique hotels may achieve higher solar self-sufficiency than large chains.
  • Location and Sunlight: Southern UK regions, like Plymouth (3 peak sun hours daily), generate more solar energy than northern areas like Edinburgh (2.4 hours).
  • Available Space: Each kilowatt-peak (kWp) of solar panels requires approximately 6–8 m² of unshaded roof or ground space.
  • Energy Efficiency Measures: Implementing LED lighting, smart thermostats, and heat pumps can reduce overall energy demand, making solar power more viable.

The Hybrid Solution

A hybrid system integrates solar PV panels, battery energy storage systems (BESS), and a grid connection. During summer months, solar panels can produce surplus energy, which batteries store for nighttime or cloudy days

The grid acts as a backup during low solar production periods, ensuring uninterrupted power. This approach maximises cost savings and energy independence while maintaining reliability.

What Can Solar Power Run in a Hotel?

Solar power can effectively run a variety of hotel operations and appliances, helping to offset electricity costs and reduce reliance on the grid. According to the Building Energy Efficiency Survey (BEES) 2014–15 published by GOV.UK, the hospitality sector (including hotels) consumes approximately 17,000 GWh of energy annually, with electricity making up 52% of this total.

Major end uses include catering, heating, lighting, and cooled storage, many of which can be powered or offset by solar PV systems.

By generating clean electricity during daylight hours, solar panels can directly supply power to electrical loads, while battery storage extends usage into the evening. This not only lowers bills but also supports sustainability goals. 

For instance, in the UK hotel and catering sector, energy costs represent 4-6% of operating expenses, with cooking and heating accounting for over half, as per data from ReLondon.
