Solar is becoming a critical enabler for businesses seeking long-term energy price certainty in persistently volatile energy markets.
One of the most useful metrics for understanding this is the Levelised Cost of Energy (LCOE).
In simple terms: LCOE is the average total cost of installing and operating a solar system, divided by the total electricity it generates over its lifetime. The resulting figure effectively represents a long-term electricity price.
For example, based on my own calculations and assumptions (which I’m happy to share), a typical 150 kWp commercial rooftop solar system in the UK could achieve an approximate LCOE of:
☀️ ~7 p/kWh over a 25-year lifecycle
By comparison, many businesses today are paying:
⚡ ~23–28 p/kWh for grid electricity - with significant year-on-year price volatility.
So, in many ways, installing solar is comparable to entering into a 25-year fixed-price electricity contract with yourself - at well below current market prices.
This is why solar is increasingly being viewed not just as a sustainability investment, but as a strategic hedge against long-term energy price volatility.
