Success Story • Cártama

Townhouse in Cártama
Historical goal: reduce the energy charge

Compact high-efficiency installation (2.34 kWp), sized from the analysed consumption profile to reduce grid purchases through self-consumption and surplus compensation.

3,947 kWh Produced/year

Case estimate Energy charge · analysed period

Consumption and Production Analysis

The system was sized from the analysed consumption profile. The aim was to match available roof capacity and generate surplus eligible for compensation; the final bill depends on consumption, tariff and fixed charges.

Annual Energy Balance

⚡ Energy Produced 3,947 kWh

🏠 Energy Consumed 2,997 kWh

🔋 Surplus (Extra Savings) +949.50 kWh

According to the internal case calculation, this surplus could reduce the energy charge during the analysed period. Future results depend on consumption, production, tariff and fixed charges.

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.
