Cost Factors

What Affects the Price?

Understanding these factors helps you budget accurately for your project

System Size

Larger systems have better value per kW but require higher upfront investment.

Roof Type

Flat roofs may need mounting frames. Tile roofs require careful installation.

Battery Choice

Lithium batteries (LiFePO4) cost more but last 10+ years vs 5-7 for lead-acid.

Grid Connection

Connecting to sell excess power requires permits and approved inverters, adding €300-600.

The Process

What to Expect When Hiring

A typical solar installation job follows these steps

1

Site Survey

The installer assesses roof orientation, shading, electrical capacity, and your energy usage.

2

3

Installation

Panels mounted, inverter installed, and system connected. Usually 1-3 days.

4

Frequently Asked Questions

Common questions about solar installation costs in Spain

A typical 5kW system produces 7,500-8,500 kWh/year on the Costa del Sol. With electricity at €0.15-0.25/kWh, savings are €1,100-2,100/year. Most systems pay for themselves in 5-8 years.
Not necessarily. Without batteries, you use solar during the day and grid at night. Batteries add €3,600-10,800 but provide backup power and maximize self-consumption. Best for properties with evening/night usage.
Yes, through 'compensación simplificada'. You won't get paid cash, but excess energy reduces your bill. Maximum compensation is limited to your consumption, so oversizing isn't beneficial for profit.
