Service repair

Certified service for battery storage, solar panels, and small wind turbines – keeping your systems running

Battery Storage Repair

Diagnose and fix issues with inverters, BMS, and lithium-ion cells. Includes thermal management calibration and safety checks.

Solar Panel Maintenance

Cleaning, wiring inspections, and inverter diagnostics to maximize efficiency. Prevents 30%+ energy loss from dust/damage.

Small Wind Turbine Service

Blade alignment, generator servicing, and structural integrity checks. Optimized for Estonia’s coastal winds and harsh winters.

Without quarterly BMS checks:

  • Thermal runaway risk increases by 40% after 18 months of neglected cooling system maintenance (per DNV GL 2023 report).

  • Capacity drops 15–25% faster due to unbalanced cells — turning a €200 calibration into a €5,000+ module replacement.

Without bi-annual cleaning & wiring checks:

  • Dust/bird droppings reduce output by 22% on average in Baltic climates (Tallinn’s humidity accelerates soiling).
  • Micro-cracks from thermal stress go undetected → full string failure within 6–12 months (documented in Fraunhofer ISE case studies).

Without seasonal blade/gearbox checks:

  • Ice buildup on blades (common in Estonian winters) causes imbalance → bearing failure → €3,000+ repair vs. €150 de-icing service.
  • Loose tower bolts (from vibration) led to 3 documented collapses in Nordic residential turbines (2021–2023, Nordic Wind Safety Database).

Don’t let preventable failures drain your energy savings. With Sunsa’s certified technician and same-day response across Estonia, keep your battery, solar, and wind systems running at 100% efficiency — no downtime, no surprises.
