As of March 2026, any solar installation in Lanarkshire above 3.68kW requires SPEN G99 pre-approval before work begins — Lanarkshire Solar Pro handles this as standard.
SPEN (SP Energy Networks, formerly Scottish Power Distribution) is the Distribution Network Operator for all of Lanarkshire. Every solar installation must be notified to or pre-approved by SPEN before it can legally export electricity to the grid.
For smaller systems — notification can be submitted within 28 days after installation. Simpler process.
Pre-approval required before installation. Virtually all 4kW+ systems fall under G99.
Why this matters for your timeline
If you're planning a 4kW+ system (the most popular choice for Lanarkshire homes), the G99 process means your installation timeline runs from booking to completion in approximately 6–10 weeks. We recommend booking your free survey early so the SPEN application can be submitted and approved before your preferred installation date.
As of March 2026, for most Lanarkshire 3–4 bedroom homes, GivEnergy 9.5kWh offers the best value at £5,500 — but Duracell 10kWh's brand recognition provides confidence for buyers who want maximum assurance.
from £5,500
Best for most 3–4 bed Lanarkshire homes.
from £5,800
Best for larger homes or buyers who want maximum assurance.
Cold Weather Safe
LFP operates down to -20°C. NMC batteries degrade rapidly in cold — LFP handles Lanarkshire winters without performance loss.
Fire Safe
LFP chemistry is inherently more thermally stable. No thermal runaway risk that some NMC batteries carry. Safe for indoor installation.
Cycle Longevity
4,000–6,000 cycles at 80% depth of discharge. A daily charge cycle for 13–16 years, outlasting most competitor batteries.

As of March 2026, a representative Motherwell 3-bed semi with 4kW solar + GivEnergy battery + air source heat pump achieved £2,640/yr saving, improving EPC from D to B band, with a 4.8-year payback.
Your panels will produce at least 80% of rated output for 25 years. Manufacturer-backed performance warranty on all panels installed.
Any defect in our installation work will be corrected at no charge, for 10 full years. Written, enforceable, specific.

As of March 2026, combining solar panels with an EV in Lanarkshire adds £350–£700/yr of additional saving by charging the vehicle from excess generation, and a further £350 OZEV grant is available on EV charger installation.
OZEV EV Charger Grant
£350 off
The OZEV Electric Vehicle Chargepoint Grant provides £350 off the cost of installing a home EV charger. Available to Lanarkshire homeowners. Lanarkshire Solar Pro installs OZEV-eligible chargers.
Smart Solar Charging
~£350–700/yr
With a battery and smart EV charger, excess solar charges your car automatically — prioritising solar over grid import. Combined with Octopus Intelligent Flux, your EV charging cost approaches zero.
Octopus Intelligent
7.5p off-peak
Octopus Intelligent Flux offers overnight off-peak rates as low as 7.5p/kWh for EV charging. Stack with solar daytime generation for near-zero EV running costs across a full year.
The Solar + Battery + EV Stack — How It Works in Lanarkshire
During the day, solar panels generate electricity. The smart inverter prioritises powering your home first, then charges the battery, then diverts excess to charge your EV (via smart EVSE), then exports the remainder to the grid at Smart Export Guarantee rates.
At night, the battery discharges to power the home, with your EV charging overnight on Octopus Intelligent's off-peak 7.5p/kWh rate. The result: a 4-bed Lanarkshire home with an EV can achieve total annual energy costs below £400, down from typically £3,500+.
