As the UK faces one of its hottest and driest summers on record, marked by drought warnings, rising energy demand, and pressure on national infrastructure, an energy revolution is unfolding.  

Amid the heatwave and headlines of crisis, solar power has quietly become a standout success story.

Why Solar Panels Thrive in Sunny Conditions?

While it’s commonly known that solar panel efficiency can decline slightly in high temperatures, the key driver of performance is not temperature; it’s the intensity of sunlight hitting the panel surface, known as solar irradiance.

During a heatwave, the UK experiences prolonged, cloud-free days with strong sunlight, which creates ideal conditions for solar power systems to operate and generate free electricity! 

The result? High-yield electricity production, even during temperature spikes.

Why Solar Power Makes Business Sense

For commercial and industrial businesses, this summer’s heatwave has been a clear demonstration of solar power’s value, not just as a long-term sustainability investment, but as a high-performing asset.

Those already using solar PV systems have seen the benefits first-hand: greater energy yield that reduces reliance on expensive grid electricity, and a faster return on investment 

At a time when grid prices are volatile and ESG scrutiny is intensifying, gains from solar PV matter more than ever. Solar PV is the practical solution for businesses to secure energy independence. 

Now is the right time to invest, and here’s why:

  • Improved ROI Faster payback from strong seasonal output
  • Energy security – Stable pricing, reduced exposure to rising energy costs
  • Tax advantages – Access capital allowances and government incentives
  • Net zero alignment – Trackable progress on carbon goals
  • Brand value – Strengthen sustainability credentials

Battery Storage: Capturing Excess Power for Long-Term Value

As solar power systems produced more energy than usual, many businesses saw an opportunity to use batteries to capture the energy that could have gone back to the grid or to waste due to export limitations. 

Those businesses equipped with battery storage systems were able to capture this surplus and reuse it during evening hours or export it to the grid at higher tariffs. 

Adding battery storage to a solar setup future-proofs investments and maximises the ROI.

Frequently Asked Questions

How did solar panels perform during the recent heatwave in the UK?

Solar panels performed exceptionally well during the heatwave, producing high yields of electricity despite high temperatures. The main factor driving their performance was the strong, prolonged sunlight, or solar irradiance, rather than temperature alone.

Why do solar panels thrive in sunny conditions despite high temperatures?

While solar panel efficiency can slightly decline in high temperatures, the intensity of sunlight (solar irradiance) hitting the panels is the most critical factor. The heatwave brought cloud-free days with strong sunlight, ideal for generating electricity.

What benefits have businesses using solar PV systems experienced this summer?

Businesses have enjoyed greater energy yields, reducing their reliance on costly grid electricity and achieving faster returns on investment. Solar power also offers energy security, stable pricing, and helps align with carbon reduction goals.

Why is now considered a good time for businesses to invest in solar power?

Strong seasonal output leads to improved ROI with faster payback. Energy cost stability reduces exposure to price volatility. Tax advantages through allowances and incentives are available. Investing in solar enhances brand value and net zero commitments.

How can battery storage complement a solar power system?

Battery storage captures excess energy produced by solar panels that might otherwise be wasted or exported at lower tariffs. This stored energy can be reused during evening hours or sold back to the grid when prices are higher, maximising ROI and future-proofing the investment.

What types of businesses can benefit from solar power and battery storage?

A variety of businesses, including logistics hubs, manufacturing sites, corporate offices, and data centers, can leverage the untapped potential of solar power on rooftops, carparks, or land.
