What's Included in Our Maintenance Service
Comprehensive care for every component of your solar installation — from panel surface to generation meter.
Annual Visual Inspection
Roof-level visual check of panels, mounting, and cabling. We identify micro-cracks, discolouration, panel damage, loose fixings, and water ingress points before they cause failures.
From £150
Electrical Safety Test
Full electrical testing of the array, inverter, isolation switches, and generation meter. Verifies all protective devices function correctly and that the system meets current BS 7671 standards.
Included with inspection
Inverter Health Check
Deep diagnostic of your inverter — error logs, voltage readings, efficiency analysis, and firmware update. Identifies early-stage faults before they cause complete shutdown.
Included with inspection
Professional Cleaning
Specialist soft-brush and purified-water cleaning removes bird droppings, lichen, moss, and dust deposits that block sunlight and degrade output. Typically restores 3–8% lost generation.
From £100
Bird Proofing
Robust aluminium mesh installed around the panel perimeter prevents pigeon nesting beneath your array. Nesting causes overheating, cable damage, and structural issues. Essential for urban installations.
From £250
Inverter Replacement
We replace end-of-life inverters with modern equivalents or upgrade to hybrid inverters compatible with battery storage. We handle all DNO paperwork and recommissioning.
From £600
Do Solar Panels Need Maintenance?
Solar panels are the lowest-maintenance electrical appliance in your home. They have no moving parts and self-clean in normal Yorkshire rainfall when installed at a pitch above 15 degrees. However, "low maintenance" does not mean "zero maintenance".
Annual visual checks catch rare but impactful issues: micro-cracks from hail or storm damage, bird nesting that causes hotspots, failing seals around roof penetrations, or loose DC cable connections that arc and degrade over time.
The inverter — the electronic heart of your system — requires more attention. After 10 years, error rates increase and efficiency drops. Proactive replacement avoids the frustration of discovering weeks of lost generation during a manual check.
For FiT-era systems installed before 2019, YEERS offers a dedicated legacy service. We assess the health of aging inverters, identify panels below performance thresholds, and advise on whether a targeted upgrade or full replacement offers the best ROI.
Signs Your System Is Healthy

- No inverter fault codes or alarms
- No visible damage to panels or frames
- Export payments arriving as expected
- Monitoring app shows daily generation curves
Warning Signs to Watch For
- Generation 15%+ below historic average
- Inverter fault light or error code showing
- Visible panel damage, discolouration, or cracking
- Bird activity or debris visible under panels
- System over 10 years old with no service history
Inverter Replacement — The 10-Year Milestone
String inverters carry a standard 10-year warranty and typically last 12–15 years in real-world conditions. If your system was installed between 2010 and 2015, you may be approaching this milestone.
Rather than a like-for-like replacement, YEERS recommends upgrading to a modern hybrid inverter. This enables battery storage to be added to your existing panel array without any changes to the roof-mounted components — often reducing the total retrofit cost by £1,000–£1,500 compared to a full system upgrade.
We handle all DNO notification, MCS re-registration, and SEG paperwork so your export payments continue uninterrupted.

Brands We Service
All brands serviced regardless of original installer.
Monitoring Your System Between Services
All modern inverters provide real-time monitoring through a smartphone app. We set up your monitoring during installation and can troubleshoot remotely — often resolving issues without a site visit. If you've lost access to your monitoring, we can help restore it at any service visit.
