How Much Money Did Your Business Waste on Electricity This Month by Not Installing Solar?

Why Commercial Solar Makes So Much Sense for Businesses

Unlike domestic properties, most commercial sites use the bulk of their electricity during daylight hours — exactly when solar panels are generating power.

This means:

  • Less electricity bought from the grid
  • Immediate savings from day one
  • No change in how your business operates

Instead of exporting energy for pennies, businesses typically use solar power directly on site, maximising its value.


The Real Savings: Thousands Per Month, Not Per Year

Commercial electricity tariffs are significantly higher than historic norms. When solar replaces grid electricity at peak rates, the savings add up fast.

Typical outcomes we see include:

  • 30–60% reduction in electricity bills
  • Four-figure monthly savings for medium to large sites
  • Protection from future price rises

Warehouses, manufacturing facilities, offices, farms, retail units, and schools are particularly well suited to commercial solar installations.


Adding Battery Storage: Control, Not Just Generation

Battery storage takes commercial solar to the next level.

A battery allows your business to:

  • Store excess solar energy instead of exporting it
  • Use stored power during peak tariff periods
  • Reduce maximum demand and peak charges
  • Maintain resilience during grid fluctuations

Many businesses also charge batteries overnight on cheap off-peak tariffs and use that energy during the working day, further cutting costs.


Fast ROI: Often Under 5 Years

One of the biggest misconceptions about commercial solar is that it takes too long to pay back. In reality, with today’s energy prices:

  • ROI is often 3–5 years
  • Systems typically last 25+ years
  • Electricity savings continue long after payback

After the system has paid for itself, solar effectively becomes a profit-generating asset on your balance sheet.


Capital Allowances & Tax Benefits

Commercial solar and battery storage systems can often benefit from tax relief, improving cash flow and shortening payback even further.

Depending on your circumstances, benefits may include:

  • Full expensing or capital allowances
  • Improved net present value (NPV)
  • Reduced corporation tax liability

(Always speak to your accountant — but the financial case is usually very strong.)


Who Is Commercial Solar Best Suited For?

Commercial solar and battery storage works particularly well for businesses that:

  • Operate mainly during daytime hours
  • Have large or flat roof space
  • Use energy-intensive equipment
  • Want predictable energy costs
  • Are committed to sustainability and net zero goals

From SMEs to large commercial estates, solutions can be tailored to almost any site.


Beyond Savings: Sustainability & Brand Value

In addition to financial savings, commercial solar delivers:

  • Lower carbon emissions
  • Strong ESG credentials
  • Improved public and customer perception
  • Alignment with net zero targets
  • Long-term energy security

Many organisations now see solar as both a financial decision and a strategic one.
