Quick Answer
Competa installations are often shaped more by the property than by the panel brand: mountain shade, traditional roofs, difficult access, pumps and long electrical runs all matter. The optimal configuration depends on your actual consumption, roof orientation, battery needs, and choosing the right export tariff.
What is genuinely local here
Village houses can have small flat terraces or fragile tiled roofs. Fincas outside the centre may have steep access, outbuildings, water pumps, older switchboards or an unreliable monitoring signal.
- Inspect roof waterproofing and structural support.
- Model horizon and mountain shade by season.
- Price transport, lifting and access before contract.
- Test earthing and inspect the existing switchboard.
- Keep batteries and inverters within their permitted temperature range.
What the site survey must establish
A useful survey records twelve months of consumption, daytime loads, roof construction, orientation, shade, cable route, earthing, access and the proposed inverter location. A satellite image alone cannot confirm roof condition, structure or electrical safety.
What a local quote should include
Require a drawing of panel, inverter and battery locations plus the cable route. The quote should state whether scaffolding, lifting, trenching, pump integration, generator integration and remedial electrical work are included.
Ask for assumptions in kWh rather than a headline saving percentage. The proposal should separate self-consumed electricity, compensated exports and grid imports, and state the tariff assumptions used.
Permissions and incentives
Municipal procedure, community approval and tax relief depend on the property and the rules in force when you apply. Do not treat an installer's verbal promise as approval.
