About This Service

Solar panels done properly

Most solar installers send a salesperson to your home, agree a system size on the spot, and schedule a one-day crew. We do it differently. Every Afta Electrical solar installation begins with a proper desktop survey — roof orientation, shading analysis, consumption data — before a single panel is quoted.

We install tier-1 panels (Jinko, Canadian Solar, REC) paired with market-leading inverters from SolarEdge, Solis, and SolaX. Panel-level optimisers are included on any roof with partial shading or mixed orientations, because a string inverter on a complex roof leaves energy on the table every single day.

Inverter selection matters

The inverter is the brain of your solar system and the component most likely to need attention over a 25-year panel warranty. We select inverter brands with strong UK spare-parts availability and responsive technical support — not the cheapest unit that ships fastest.

DNO applications handled for you

Systems above 3.68kW require notification to your Distribution Network Operator. For systems above 16A per phase, a G99 application may be needed — a process that can take 8–12 weeks. We manage this from the outset, so it does not delay your installation or invalidate your installation certificate.

Smart Export Guarantee eligibility

Every system we install is professionally installed, making you eligible for Smart Export Guarantee (SEG) tariffs from energy retailers. We provide the installation certificate and all documentation needed to apply. Current SEG rates typically range from 4–15p per kWh exported.

Scaffolding included

All roof work pricing includes scaffolding erection and dismantling. We do not sub-contract scaffold crews — our installation schedule accounts for the full access period.

Tier-1 panels only

Jinko, Canadian Solar and REC panels with 25-year product and performance warranties. No grey-market stock.

Panel-level monitoring

SolarEdge optimisers or microinverters available on every installation. Identify underperforming panels individually.

Full system certification

Issued on completion. Required for SEG tariff applications and for adding battery storage later.

10-year workmanship warranty

Covering our installation labour — brackets, cable runs, roof penetrations, inverter commissioning.

Part P compliant

All electrical work self-certified under Part P of the Building Regulations. Certificates issued to your local authority.

Question 1 of 9
What type of property is it?
This helps us understand roof size and system potential.
Question 2 of 9
Do you own the property?
Solar panels are typically only installed on owner-occupied or landlord properties.
Question 3 of 9
What type of roof do you have?
Most roof types are suitable — we just need to know what we are working with.
Question 4 of 9
Which direction does your roof mainly face?
South-facing roofs generate the most energy — but east/west can still be very viable.
Question 5 of 9
Is there significant shading on your roof?
Trees, chimneys, dormers or neighbouring buildings can all affect output.
Question 6 of 9
What is your approximate monthly electricity bill?
This helps us estimate savings and recommend the right system size.
Question 7 of 9
Are you interested in battery storage?
A battery stores surplus solar energy to use in the evening — maximising your self-sufficiency.
Question 8 of 9
Do you have or plan to get an electric vehicle?
Solar + EV charging is a powerful combination that can significantly reduce running costs.
Question 9 of 9

Common Questions

Solar PV FAQs

Does my roof need to face south?
+
South-facing is optimal, but east- or west-facing roofs still generate 80–85% of a south-facing equivalent. We model your specific orientation and pitch before quoting, so you'll know exactly what to expect. North-facing panels are rarely viable unless on a very shallow pitch.
What is installation certification and why does it matter?
+
Installation certification is the industry-standard quality requirement that covers both the installer and the installation. Without an approved installation certificate you cannot access Smart Export Guarantee tariffs — meaning you'll receive nothing for the electricity you export to the grid. It is also required if you want to add battery storage at a later date.
How long does a solar installation take?
+
Most residential installations are completed in 1–2 days. Larger systems (8kW+) or those requiring a G99 DNO application may take longer to commission, though the on-roof work is typically still one day. We handle all DNO paperwork in advance so it does not delay your installation date.
Can I add a battery later?
+
Yes. We design every system to be battery-ready, with the inverter and cabling spec'd to accommodate storage. Adding a battery retrofit later is straightforward. If you're considering battery from the outset, a combined solar and battery package often works out more cost-effective — see our Solar + Battery Packages page.
Do I need planning permission?
+
In most cases, domestic solar panels are permitted development and do not require planning permission — provided the panels don't protrude more than 200mm from the roof plane and the property isn't listed or in a designated area. We'll advise if your situation is an exception.
What's the typical payback period?
+
For a typical 4kW system on a property with moderate daytime consumption, payback is currently 7–10 years based on avoided import costs and SEG export income. Self-consumption rate and your current electricity tariff are the biggest variables. Adding battery storage can reduce payback time by improving self-consumption to 80%+ year-round.
