In Spain, skylight installation costs €800–€3,000 per unit installed. Labor rates are lower than Northern Europe at €400–€1,000 per skylight. VELUX and Roto are the main brands. Heat gain is a significant concern in Spain — look for solar-control glazing (cristal de control solar) with a g-value below 0.30 to prevent summer overheating. The CTE requires solar protection for skylights in climate zones C through E.

What affects the cost?
- Skylight type — fixed is cheapest, solar-powered vented is most expensive standard option
- Size — standard sizes (21×27 to 30×46 inches) cost less than custom dimensions
- Roof type — asphalt shingles are easiest; tile, metal, and flat roofs cost more to cut and flash
How to save on skylight installation
- Choose fixed over operable — fixed skylights cost 40–50% less and have fewer leak points
- Claim tax credits — US solar-powered VELUX skylights qualify for the 30% federal solar tax credit
- Use standard sizes — custom dimensions cost 50–100% more than stock sizes
