Which Businesses Can 50kW Solar Panels Work For?

A 50kW solar system is usually suitable for medium to large sized businesses depending on their energy needs. If you’re using around 500kW of energy per day, then a 50kW solar system will suffice. But we appreciate you might not know your business’ energy use off the top of your head, so you won’t know how much generated energy you’ll need from your panels. To help, here are a few examples of businesses that successfully use 50kW systems for their business needs:

  • Office buildings
  • Hospitality settings
  • Schools
  • Small-Medium farms


How suitable a 50kW system is for your business really depends on your business’ energy needs, rather than your business type. Compare Solar Suppliers with us today, and we’ll be able to put you in touch with MCS Certified local installers, who can talk through your options with you. 

How Much Does A 50kW Grid Solar System Cost?

A 50kW system will typically cost from £45,000-£55,000 depending on the supplier you choose to go with and the exact number of solar panels you require.

Remember: Different types of solar panels will produce different amounts of energy, so the exact amount of solar panels you’ll require for a 50kW solar system will differ depending on the type of solar panels you opt for in your solar array.  

How Will I Cover The High Upfront Cost Of Solar Panel Prices?

Most asset finance providers are only too happy to provide finance to businesses looking to opt for greener energy solutions, and solar is no exception!

We can put you in touch with asset finance providers who will cover the upfront cost of your solar installation and you can repay them over a period of ten years, with help from the energy bill savings you’ll make during that time.

If you have the capital to invest in a 50kW grid solar system for your business right now, then you could also rely on tax relief from the Annual Investment Allowance to help reduce the cost.

This allows businesses to offset 100% of the cost of their new solar panels against their taxable profits, helping reduce their corporation tax bill, and effectively reducing the cost of going solar by 19%. 

It’s also worth considering the savings you’ll make each year too, thanks to the reduction in your energy costs…

How Much Will A 50kW System Save Me Per Year?

Large, medium, and small businesses will all save money with solar panels, and many businesses will find those savings to be significant!

Typically, a 50kW solar system will save an average of around £10,561 per year, but this will vary depending on your annual energy bills typically and how optimal conditions are (such as no shading and your panels being south facing).

Energy prices change frequently, meaning your annual savings may be more or less than this, depending on the energy prices at the time of your comparison. Regardless, five-figure savings are common and you should expect to see similar savings per year. 

If your savings amounted to the average of £10,561 per year, and your new 50kW system cost around £45,000, you could expect to have covered the full cost of your system in less than 4.5 years, with just the money you save on your bills!

What Will A 50kW Solar System Usually Include?

Although each 50kW system will look a little different, a 50.1kW system ideal for office buildings from our usual installer partners will include:

  • 92 x 545W Canadian Solar Panels
  • 50kW 3-Phase Solis String Inverter
  • MCS Certified Equipment And Installers
  • 25 Year Panel Performance Guarantee
  • Extended Inverter Warranty


All with prices starting from £45,000.

50kW Solar Panel System FAQs:

A 50kW system will typically have around 100 solar PV panels, so as you can imagine, it will take multiple days to get everything up and running for your business. How long it will take exactly will depend on your location, the size of the installation, and any additional requirements to ensure the work can be carried out as safely as possible.

In most cases, no, as it will come under ‘Permitted Development’ for a commercial setting. If the panels are to be ground mounted or don’t meet the conditions laid down regarding size of the system, height, distance from the property boundary, and visibility, then planning permission may be required. 

Talk to the local installer we put you in touch with to find out if planning permission is required for your solar project.

You may need to discuss your installation plans with your distribution network operator (DNO) if you’re planning such a large installation. With a large enough roof space you could create a solar farm with the capacity to provide power to others in your local area. That creates a load issue on the national grid, though, and your DNO will need to be informed to ensure the grid isn’t overloaded, causing issues for everyone.

It surprises most business owners, but there’s very little in the way of maintenance costs for a 50kW system for your business. Besides solar maintenance once a year to make sure everything is in working order, and cleaning twice a year, most solar panels need very little input from their owners. 

Cleaning and maintenance packages are available with a range of installers for a reasonable price.
