How Business Solar UK Can Help

Warehouses are often the ideal place for solar panels because:

  • Energy demands are usually high in the daytime when solar panels are productive
  • Warehouses have large, empty roof spaces that can accommodate a large, powerful solar system
  • Warehouse roofs are usually easy to access and build on, reducing the cost of construction


Businesses can save themselves a huge amount of money, help the environment and avoid being at the mercy of power companies by powering their warehouse with solar panels.

What are the Rates of Return and Energy Production Capacity?

Before we discuss the benefits and drawbacks of solar power in more depth, we’ll give you the most important figures on solar investment for warehouses.

What are the Typical Rates of Return?

Typical rates of return for warehouse solar investments are around 15%. This means that the initial industrial solar panels investment is typically paid off within 6-7 years. With solar panel systems normally coming with a 25 year warranty, this means that most businesses will benefit from at least 19 years of free electricity.

Rates of return can, in fact, be higher. In the right circumstances and with the use of the annual investment allowance, rates of return on a commercial solar investment can be as high as 25%.

How Much Energy Do Solar Panel Systems Produce?

So that you can see how much of your total energy demands you’ll be able to meet with a solar panel install, here is how much electricity solar panel systems of different sizes will typically produce. Note that output does vary slightly depending on the weather and local conditions.

We’ve also given figures on the total savings this will provide, based on an electricity price of 35p/kWh.


Roof Space m2

Electricity Output

Annual Savings


110.1 kW

68,811 kWh



250.7 kW

156,691 kWh



501.4 kW

313,379 kWh



The amount of electricity that you can generate depends on the size of your solar panel system. Usually, this is dictated by the size of the roof space. The bigger the system, the more electricity it generates.

It should be noted, however, that it is necessary to match the size of a solar power system to the energy demands of your business. While most businesses will simply need to aim for maximum output, where energy demands are low, it may be necessary to actually reduce the size of the solar PV system.

Legislation and Business Practices are Changing

Another thing to consider is that, as well as consumers preferring environmentally friendly businesses, there’s now more legislative and inter-business pressure to adopt more sustainable practices.

Large businesses are often up to speed on the issue of environmental friendliness, but small and medium sized enterprises (SMEs) are often less so. Where SMEs exist in the supply chains of larger businesses, it may pay to take measures to embrace renewable energy now. For more complete information on how important environmental friendliness is becoming to SMEs, check out this guide from the British Business Bank

Low Maintenance

The final thing to mention with solar panels is that they’re low maintenance. This may not seem like an important point, but it means that a solar panel investment is usually a very reliable and predictable one. Most solar panel systems, after they’re fitted, only need to be checked occasionally and to have very basic cleaning and maintenance tasks carried out on them.

If your warehouse is in a very dusty area, then more regular cleaning may be required to ensure that efficiency levels are maintained. However, generally speaking, solar panel systems are a very straightforward investment. The overheads are very minimal and the only major consideration is the initial installation costs.

Is installing Solar Panels a Good Investment?

Here are the main things to think about when deciding whether or not to invest in roof solar panels for your warehouse.

Financial Savings

The big benefit of adding solar panels for warehouse environments is that they consistently offer businesses improved energy efficiency and therefore savings on energy bills. According to UKWA, solar panels can reduce warehouse electricity costs by 40-80% annually.

Warehouses can accommodate large, highly productive new solar power systems that match well with high daytime demands for electricity. On top of this, the construction of a warehouse solar system is also usually more economical than in other locations. This reduces the amount needed for the initial investment.

As a result of this, solar panels offer a quick return on investment and a big cost saving. As we said earlier, a typical warehouse solar panel system will provide at least 19 years of free electricity. For a 250.7 kW system, for example, this will equate to a total saving of over £1 million. Solar panel systems can last in some situations for as long as 40 years.

Energy Costs

Warehousing energy costs represent a major challenge to businesses. Warehouse solar panel installation means a reduction in the amount a business spends on energy, and that the business won’t be at the mercy of energy company price fluctuations.

With a solar panel system, you’ll be able to guarantee a consistent amount of free electricity for your business. This makes business planning for the warehousing sector easier and protects them from the effects of price fluctuations. This benefit is even more relevant nowadays, given the high level of volatility in the energy markets.

Environmental Benefits

Having a solar panel system will also mean that your business is doing some good through the adoption of renewable energy technology that produces its own green electricity, rather than over reliance on fossil fuels. According to the UKWA, solar panels for warehouses reduce carbon emissions by between 13 and 130 tonnes per year

Electricity generated by solar panels is environmentally friendly, and you’ll have the satisfaction of knowing that your business is doing its part in relation to its carbon footprint. As well as providing personal satisfaction, this could also be good for your business reputation with customers.


As you can see, there are plenty of reasons to invest in commercial or industrial scale solar panels for a warehouse.

  • Warehouses have large roofs
  • Installing solar panels on a warehouse roof is easier
  • Warehouses usually have high daytime demands for energy (which is when solar panels are productive)
  • Solar panels boost a business’ environmental credentials
  • More secure power supply and less reliance on national grid
  • Protection against rising energy costs and price volatility
  • Greener power to cut carbon emissions


All these things combine to make warehouses the perfect place for commercial solar panels to be installed and for businesses to enjoy the benefits that result from bespoke solar systems.
