Townhouse in Cártama
Goal: €0 Bill

Compact high-efficiency installation (2.34 kWp) designed to neutralize electricity consumption through net metering.

3,947 kWh Produced/year

100% Compensation

Consumption and Production Analysis

This project is a perfect example of precise sizing. The goal was not to fill the roof with panels, but to install the exact power needed to cover annual consumption and generate enough surplus to offset fixed costs.

Annual Energy Balance

⚡ Energy Produced 3,947 kWh

🏠 Energy Consumed 2,997 kWh

🔋 Surplus (Extra Savings) +949.50 kWh

This surplus allows reducing the consumption term of the bill to €0.

Technical Configuration

For a semi-detached house with limited space, we opted for high-efficiency modules:

6x Trina Vertex S 390W Panels: Full Black technology for total aesthetic integration.
Huawei 3KTL Inverter: Slightly oversized relative to panels to allow future expansion of 2-3 more panels if consumption increases (electric car).
Coplanar Structure: Guaranteed wind resistance in exposed area.
