With the clocks going forward and daylight hours increasing, spring is one of the smartest times of year to get solar panels installed. You’ll have your system up and running before peak summer generation, meaning you benefit from the best months of output from day one.
If you’re not sure where to start, take a look at our Solar PV installation page for an overview of what’s involved.
Why Install Solar Panels in 2026?
Many homeowners wait until summer to think about solar, but by then installation queues are at their longest. Getting ahead in spring means a quicker turnaround, no summer backlog, and full generation through the warmest, brightest months of the year. It’s a straightforward decision that pays off quickly.
How Much Can Solar Panels Save You?
With UK electricity prices still elevated, a well-sized solar PV system can significantly reduce what you pay to the grid. Most homeowners see a meaningful drop in bills from the first month, with the system paying for itself over time through both savings and energy exports via the Smart Export Guarantee (SEG).
Pair your panels with a solar battery and you can store unused daytime generation for evening use, pushing your self-sufficiency even further.

What Size Solar Panel System Do You Need?
System size depends on your household’s electricity usage, roof space and orientation. As a rough guide:
- Smaller homes or low usage: 6–8 panels (around 2.5–3.4kWp) typically covers the basics.
- Average family home: 10–12 panels (around 4.25–5.1kWp) is a common starting point.
- Larger homes or higher usage: 14+ panels may be appropriate, especially with an EV or heat pump.
A proper survey is the only way to size a system correctly for your property. You can request a free quote from Solum GB and we’ll assess your home before recommending anything.

Solar Panels and Battery Storage
Installing battery storage alongside your solar panels means you’re not just generating clean energy, you’re actually using more of it. Rather than exporting surplus power back to the grid at a low rate, a battery lets you draw on that stored energy in the evenings or on overcast days.
It’s one of the most effective ways to maximise the return on your solar investment. Find out more on our best solar batteries for home page.
Is My Home Suitable for Solar Panels?
Most homes in southern England are well-suited to solar PV. South, southeast or southwest-facing roofs with minimal shading will perform best, but east and west-facing roofs can still generate a solid return. Flat roofs are also an option with the right mounting system.
Our team covers Bournemouth, Southampton, Winchester, Salisbury, Poole, Andover, Guildford and surrounding areas. If you’re in the south of England, we can likely help.
