Solar ROI — the Real Numbers
Based on a mid-range 4.5kWp system costing £7,200 installed.
9–12 yrs
Typical payback period
£610–£1,000
Estimated annual benefit
1p–25p/kWh
SEG export rate range
Battery Pairing
A battery typically adds 20–25 points of extra bill savings by using your own power in the evening instead of exporting it at a lower SEG rate.
Solar + Heat Pump
The strongest pairing in eco-home upgrades — a heat pump’s demand peaks exactly when solar output falls each winter. See the integration guide.
Grants & Incentives
Does Your Home Qualify?
- Roof age: 5–10+ years of remaining life recommended
- Space: 25–30m² for a typical 4.5kWp system
- Orientation: south ideal; east/west still delivers 85–90% output
- Shade: at least 3 hours of unobstructed sun daily
- Planning: most homes qualify for permitted development
- Structure: flat roofs need mounting frames (+£1,500–2,500)
Common Solar Panel Questions
[faq-section heading=”Common Solar Panel Questions (FAQs)”]
Q: Do solar panels work on cloudy UK days?
A: Yes, typically at 25-50% of rated capacity. UK winter days offer fewer peak-sun hours, but panels generate year-round.
Q: How long do solar panels last?
A: Most reputable panels carry 25-year warranties and keep producing meaningfully beyond that.
Q: Do I need a battery with solar?
A: No — but a battery typically adds 20-25 percentage points of extra bill savings.
Q: Should I wait for cheaper panels?
A: Panel prices have been broadly flat. The 0% VAT window closes 31 March 2027, so installing sooner locks in the saving.
Q: What maintenance is required?
A: Very little — UK rainfall keeps most panels clean. An inspection every couple of years (£100-200) is a sensible precaution.
Q: Can I add solar to an existing heat pump or EV charger setup?
A: Yes — retrofitting solar onto an existing setup is routine for MCS installers.
Q: What happens to my SEG payments if I switch energy supplier?
A: SEG is separate from your import tariff — you can take it with a different supplier to the one you buy electricity from.
