In a world facing steep electricity price rises, many of us are looking for renewable, sustainable and independent sources of power. So why choose solar energy, and specifically, solar PV?
Let's look into each of these solar power benefits in more detail.
A well-sized PV solar energy system - combined with storage if the usage is primarily in the morning/evening - can cover a significant portion of your home or building's annual electricity usage, up to 70-80% in many cases.
What this means is that for the majority of the year the building will be powered by 100% clean solar electricity, much to the annoyance of your electricity supplier!
Alongside the grid independence and environmental benefits, the Smart Export Guarantee (SEG) provides an economic incentive. Any excess solar energy generated by a PV system can be exported to the grid. The electricity exported to the grid is remunerated at a fixed or variable rate determined by the supplier, which is likely to be in the region of 15p/kWh. Assuming 50% export and at a rate of 15p/kWh, this roughly equates to an extra £75.0 per year on top of the electricity savings for every 3 or 4 panels installed.
In 2024, renewables crossed 50% of UK electricity generation for the first time, a historic milestone (DESNZ, DUKES 2025). Solar helped make that happen, and every new installation pushes that number higher.
The graph below tells a stark story. UK electricity prices have more than doubled since 2021, driven by the global energy crisis triggered by Russia's invasion of Ukraine. Although prices have eased slightly from their 2023 peak, they remain more than 50% higher than pre-war levels, and with ongoing volatility in global energy markets, there is no guarantee of a return to what we once considered normal. Installing solar panels means generating your own electricity and insulating yourself from price shocks you can't control.

A solar PV system will give you protection against rising energy prices as you are in effect purchasing your power in advance. Overall the lifetime cost of domestic solar electricity is now around 9p per kWh (which is well below the typical 22.36p domestic tariff rate!).
In fact if prices rise much further owning solar panels will be like owning a mobile phone… you just can’t afford not to!
