Plain English
What solar electrical work actually involves
A solar PV system is two trades, not one. Roofers (or panel installers) handle the rooftop work: rails, panels, weatherproofing. Electricians handle everything from the rooftop cable downwards: inverter wiring, isolators, consumer unit connection, DNO notification, commissioning. We're the second half.
The electrical side is where most of the technical compliance sits. BS 7671 wiring rules, MCS standard sign off, DNO (Distribution Network Operator) notification to SSEN, lockable isolators on both DC and AC sides, RCBO sizing on the consumer unit. Get any of these wrong and the SEG payments don't start, the install can't be commissioned, and any future electrical work on the property triggers a fail on the inherited installation.
We work two ways. Either we do the full job end to end (we coordinate the roofer, you get one quote, one invoice, one team to call), or we work as the electrical sub for an existing roofer or solar company you've chosen. About 60% of our solar work in Fraserburgh is electrical only, picking up after a roofer has done the panels.
The 6 components we install
From rooftop cable to SEG handover
Every solar electrical install includes these six elements. Skipping any one of them will fail an MCS audit or DNO inspection.
- 1
DC side wiring (panels to inverter)
From the rooftop panels through the loft or roof void to the inverter location. UV resistant, weather rated DC cable. Strain relief at every penetration. Earth bonding throughout. Where multiple strings are connected, an MC4 combiner where appropriate.
- 2
Inverter location and mounting
Wall mounted in a ventilated, dry, accessible location, typically utility room, garage, or loft hatch space. We confirm thermal headroom and minimum air gap during the survey. Pre-2024 installs sometimes need relocating for compliance with newer ventilation rules.
- 3
DC and AC isolators (mandatory)
Lockable DC isolator on the panel side of the inverter, lockable AC isolator on the grid side. Both must be accessible from outside the property for SSEN engineer use during a power cut. Required by BS 7671, MCS, and the DNO. Most common audit fail on inherited installs.
- 4
Consumer unit connection + RCBO
Solar AC output terminated into a dedicated RCBO on the existing consumer unit, or a sub board if main unit is full. We size the RCBO to the inverter spec, label everything clearly so future electricians can isolate the array safely.
- 5
DNO notification (G98 or G99)
G98 form for inverters under 3.68kW per phase (most domestic), G99 for larger or three phase systems. Submitted to SSEN within 28 days of commissioning. We handle this end to end, you don't fill anything. Without it, the SEG payments don't start.
- 6
Commissioning + SEG handover
First power up, full output test under load, MCS commissioning sheet completed, SEG application paperwork prepared and forwarded to your chosen export tariff supplier (Octopus, EDF, Eon, Scottish Power all participate). You start earning on the export from day one.
The MCS angle
Why MCS qualification matters more than people realise
MCS stands for Microgeneration Certification Scheme. It's the standard that Ofgem and the major energy suppliers require for any small scale renewable installation that wants to claim export payments under the SEG (Smart Export Guarantee).
Without MCS sign off, the system can be technically correct, fully compliant with BS 7671, and still not earn you a penny from exports because Octopus, EDF, Scottish Power, Eon, and the rest won't register a non MCS system on their export tariffs. For most solar installs, that's £200 to £400 a year of lost income.
We're MCS aligned. That means our work meets the standard, our certificates are accepted by every major UK supplier, and your SEG application goes through first time without back and forth. We don't charge a premium for MCS, it's how we work as standard.

What can affect the price
- •Cable run from inverter to consumer unit. Standard install assumes up to 8 metres. Longer runs add £20 to £40 per metre.
- •Consumer unit upgrade. About 40% of older AB43 properties need this alongside the solar work, factor in £550+.
- •Granite cottage or solid stone wall. Routing AC cable from inverter to consumer unit through stone walls adds 1 to 2 hours of chasing labour.
- •SSEN G99 application (for systems over 3.68kW or three phase). DNO consent fees vary, typically £150 to £400 paid to SSEN directly.
Solar + EV + battery
The combined economics get really good
Solar alone has a 9 to 12 year payback in Fraserburgh given the latitude. Add an EV charger that diverts surplus solar (Zappi, see EV page) and the payback shifts to 6 to 8 years because you're displacing the most expensive electricity (peak rate driving) with the cheapest (free midday solar). Add a battery and you flatten out the export rate problem, store at midday, use at 6pm peak.
We do all three trades under one job spec when customers want the combined install: solar electrical + Zappi + battery. Single project, single invoice, single MCS handover. About 30% of our solar customers in Aberdeenshire pair with a Zappi at the same time.
Local realities
Solar at 57.7° North, what to expect in Fraserburgh
Fraserburgh sits at 57.7° North, similar to Hudson Bay in Canada. Solar generation here is 30 to 40% lower per kWp than Cornwall or Sussex, but the long summer days partially compensate. A typical 4kW domestic array generates 3,200 to 3,800 kWh a year here, which is roughly £600 to £800 of electricity displaced annually plus another £150 to £350 from SEG export. Total annual benefit £750 to £1,150.
Coastal weather is the bigger consideration. Salt air corrodes panel mounting hardware faster than inland UK. We spec marine grade stainless fixings and seal every roof penetration with EPDM rather than silicone. Every solar electrical install includes a 5 year visual + electrical inspection contract for £120 a year, optional but recommended on harbour front and exposed properties.
Roof orientation matters more here than further south. South facing 30° to 40° pitch wins. East and west are workable (about 80% of south facing yield). North facing or heavily shaded roofs are usually uneconomical. We run a free yield estimate before quoting so you see realistic numbers, not a sales pitch.
Common questions
Solar Panel Electrical FAQs for Fraserburgh
Do I need an MCS qualified electrician for solar in Fraserburgh?
Yes if you want to claim SEG (Smart Export Guarantee) payments, which is the main income from a solar install. The MCS standard is what energy companies require to register your system for export tariffs. We're MCS aligned, meaning we work to the standard and our certificates are accepted by Octopus, EDF, Scottish Power, Eon, and the other major suppliers. For solar work that's purely educational or off grid (caravan, shed, garage), MCS isn't needed.
What's the difference between a solar installer and a solar electrician?
Most solar installers do the panels and the inverter, then sub contract the electrical side (RCBO, isolators, consumer unit work, DNO notification) to an NICEIC qualified electrician. We're often that sub contractor for Aberdeenshire roofers and solar companies. We also do full solar electrical installs end to end where the customer wants the same team for the panels and the electrical work, in those cases we coordinate with a roofer for the panel install.
How long does a solar electrical install take?
Electrical only (you've got panels, you need inverter wiring, isolators, DNO submission): 4 to 6 hours on the day plus 1 to 2 hours of paperwork on our end. Full PV electrical (we coordinate panels + electrical): 1 to 2 days for a typical 4kW domestic array. Battery hookup to existing panels: 3 to 4 hours. We give you a written timeline before booking.
Will solar work in Fraserburgh given the latitude and weather?
Yes, but expect 30 to 40% less generation than a south coast UK install. Fraserburgh sits at 57.7° North. Typical 4kW domestic array generates around 3,200 to 3,800 kWh per year here, versus 4,200 to 4,800 kWh in Cornwall. Long summer days (18+ hours of daylight in June) compensate somewhat for lower winter output. North facing or partial shade roofs are sometimes uneconomical, we run a free yield estimate before quoting.
Do I need to upgrade my fuse box for solar?
Sometimes. Older Fraserburgh consumer units (pre 2008) may not have a spare way for the solar AC output, or may need an upgrade to the metering arrangement at the supply head. About 40% of solar electrical installs in older AB43 properties trigger a consumer unit upgrade as part of the work. We assess this in the survey and quote both jobs together if needed, no surprise add ons.
What's the SEG and how much can I earn?
Smart Export Guarantee. Your supplier pays you for any solar electricity you export back to the grid. Rates vary widely: Octopus Outgoing can be 15p+ per kWh, others are 5 to 8p. A typical 4kW domestic array in Fraserburgh exports 1,500 to 2,500 kWh per year. At 8p that's £120 to £200 annual income; at 15p that's £225 to £375. Plus the savings on imported electricity you no longer buy (typically £400 to £600 annual), so total annual benefit £520 to £975.
Should I add battery storage at the same time?
Depends on your usage pattern. If you're home during the day and use most of the solar as it generates, battery is lower priority. If you're out of the house 9 to 5 and most generation goes to export at low rates, battery storage flips the economics, store now, use at 6pm peak rate. Tesla Powerwall, Givenergy, Sonnen, Pylontech all common. We do the electrical hookup for £350 to £450 if panels are already there, or bundle into a new install.
Can you install just the electrical side if I'm getting panels from someone else?
Yes, this is a big part of what we do. You hire a roofer or solar company for the panels (sometimes cheaper than a full service installer). We handle the inverter wiring, isolators, RCBO, consumer unit work, DNO notification, MCS sign off, and SEG commissioning. Coordination between the roofer and us is something we do weekly. £680 base for inverter electrical + DNO, more if consumer unit work is needed.
