How Much Does a Solar Installation Cost 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.

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.
