One contractor. Full system delivery.

Solar is a multi-discipline job. We bring in our MCS-approved partner (Tate Electrical Ltd) for the panels and system design, and we handle every part of the electrical integration ourselves. You deal with one person from start to finish.

Site survey & design

Roof inspection, shading analysis, panel layout, inverter sizing. Done properly, not from a satellite image.

MCS-approved install

Panels, mounting, DC cabling and inverter installed by our MCS-approved partner — required for Smart Export Guarantee claims.

AC electrical integration

All the AC side handled in-house by Evertek: isolators, consumer unit work, generation meter, DNO notification.

Battery storage (optional)

Tesla Powerwall 3, GivEnergy, SolarEdge Energy Hub — fully integrated with the PV inverter at install time.

EV charger integration

Pair your solar with a Zappi or Ohme charger so surplus generation charges your car instead of being exported.

Commissioning & handover

Full system test, app setup, generation monitoring, MCS certificate, and your Smart Export Guarantee application supported.

Solar PV pricing for Hampshire homes.

All systems include MCS certification and Smart Export Guarantee paperwork. 0% VAT applied (UK government scheme runs until 31 March 2027).

How solar PV pays for itself in Hampshire

A 4kWp system in Fareham typically generates around 3,400 to 3,800 kWh per year. If you use 50% of that yourself (self-consumption) and export the rest at 15p/kWh on a tariff like Octopus Outgoing Fixed, here's the rough maths:

Self-used electricity: ~1,800 kWh × 27p (import rate avoided) = £486/year saved
Exported electricity: ~1,800 kWh × 15p = £270/year earned
Total annual benefit: ~£756/year
Payback on £7,500 system: roughly 10 years

Add an EV charger and the self-consumption rate jumps to 70%+, which significantly shortens payback. Add battery storage and you can shift more import to off-peak rates.

What we never do

Pressure-sell. We're not commission-paid — there's nothing in it for us to oversize your system.
Hide the inverter brand. Some installers fit cheap unknown inverters. We tell you exactly what's going in (typically GivEnergy, SolarEdge or Sungrow).
Skip MCS. If it's not MCS-certified, you can't claim Smart Export Guarantee. Every system we install is MCS.

Solar PV FAQ

How much does solar PV cost in Hampshire in 2026?

A typical 4kWp solar PV system in Hampshire costs £6,500–£8,500 fully installed in 2026. A 6kWp system runs £8,500–£11,000. Add £4,000–£6,000 for battery storage. Solar PV is currently zero-rated for VAT in the UK until 31 March 2027.

What size solar PV system do I need?

For a typical Hampshire 3-bed home using 3,500 kWh/year, a 4–5kWp system is the sweet spot. If you have an EV or heat pump, scale up to 6–8kWp. Roof orientation matters — south-facing is ideal but east-west splits actually work better for self-consumption (you generate spread across the day rather than peaked at midday).

How long do solar panels last?

Modern solar panels carry a 25–30 year performance warranty, guaranteeing at least 80–85% of their original output after that period. Inverters typically last 10–15 years and may need replacing once in the panels' lifetime. The system as a whole reliably produces electricity for 30+ years.

Do solar panels work in Hampshire's cloudy weather?

Yes. Solar panels generate from daylight, not just direct sunshine, so they produce useful output on overcast days. Hampshire averages 1,600–1,800 hours of sunshine per year — a 4kWp south-facing system typically generates 3,400–3,800 kWh annually, similar to the average household's electricity use.

Is the Smart Export Guarantee still available in 2026?

Yes. The Smart Export Guarantee (SEG) requires energy suppliers with over 150,000 customers to offer payment for exported solar electricity. Octopus Outgoing and similar tariffs pay 4p–15p per kWh exported depending on supplier and tariff. MCS certification of your installation is required to claim it.

Can I add battery storage later?

Yes — but it's significantly cheaper to install it at the same time as the PV. Retrofit battery installation typically costs £500–£1,500 more than fitting it during the original install due to additional electrical work, scaffolding visits and commissioning. If you can stretch to it at install time, do it.

Do you handle the DNO notification?

Yes. All solar PV installations need to be notified to Scottish & Southern Electricity Networks (SSEN — the DNO for Hampshire). We handle the G99 or G98 notification on your behalf as part of the install. You won't need to fill in any forms.

What if my roof isn't suitable?

We'll tell you honestly at survey stage. North-facing roofs with heavy shading rarely pay back. Steeply pitched south-facing roofs are perfect. Flat roofs work fine with ballasted mounting. If your roof genuinely won't work, we'll tell you — we'd rather lose the job than install a system that disappoints you.
