Comparison: Grid vs Off-Grid
| Factor | Grid Connected | Off-Grid System | Notes |
|---|---|---|---|
| Grid Connection | €15,000-€80,000 | €0 | Depends on transformer distance |
| Solar System | €8,000-€15,000 | €15,000-€25,000 | Off-grid needs more capacity |
| Batteries | €5,000-€10,000 | €10,000-€30,000 | Off-grid requires more autonomy |
| Monthly Bill | €200-€500/mes | €0/mes | Continuous off-grid savings |
| Maintenance | €100/año | €300/año | Generator requires service |
| 20 Year Total | €71,000-€145,000 | €31,000-€61,000 | Off-grid saves 50-60% |
Off-Grid Advantage in Rural Mijas
For properties >500m from the electrical grid, off-grid systems are more economical than grid connection. Plus, they provide complete independence and protection against price increases.
Frequently Asked Questions
Off-grid solar systems in Mijas cost €15,000-€25,000 for basic setups (5-8kW solar + 20kWh batteries), €25,000-€40,000 for standard homes (10-15kW + 30-40kWh), and €40,000-€80,000 for luxury villas (20kW+ + 50kWh+). Costs depend on consumption, autonomy days required, and backup systems.
Rural properties in Mijas typically need: 8-12kW solar for modest fincas (100-150m²), 15-20kW for family homes (200-300m²), and 25kW+ for luxury estates. Battery storage should provide 3-5 days autonomy, typically 30-60kWh. We calculate exact requirements based on your specific needs.
Yes, Mijas receives 2,800+ sunshine hours annually with good winter production. December-February still provides 60-70% of summer output. With properly sized batteries (4-5 days autonomy) and optional backup generator, off-grid systems provide 99.9% reliability year-round.
Grid connection to rural Mijas properties costs €15,000-€80,000 depending on distance from nearest transformer. Properties >500m from grid often find off-grid solar cheaper. Off-grid eliminates monthly bills (€200-500/month) and connection delays (6-18 months).
Backup options include: diesel/gas generators (€2,000-€8,000) for emergency power, wind turbines (€5,000-€15,000) for winter supplement, additional battery banks for extended autonomy, and hybrid inverters that seamlessly integrate all sources. Most Mijas off-grid systems include 5-10kW backup generators.
Yes, hybrid systems allow grid-tie with off-grid capability. During outages, the system islands automatically, providing backup power. This offers energy independence while maintaining grid connection for extreme situations. Popular for Mijas properties with unreliable grid supply.
