Solar PV for a home in Fuerteventura: designing the system with the building
Abundant sun makes solar attractive, but output and durability depend on orientation, shade, wind, salt exposure and the actual consumption profile.
Where to begin
Estimate annual demand and its hourly pattern before deciding array size and storage. Reserve an unshaded, accessible roof zone compatible with waterproofing and maintenance. Across Fuerteventura, sunlight, wind, salt exposure, access and service availability vary considerably. A decision that looks sound in theory can become inefficient on the wrong plot.
Technical decisions
Engineer fixings, ballast and support for site-specific wind loads. Choose components and connections suited to heat, dust and possible salt exposure. A useful quotation states what is included, what is excluded and which assumptions have been made. A stand-alone figure without a design or plot assessment is only an early reference.
Budget, timing and checks
Assess batteries, load management and car charging against actual use rather than as automatic additions. Coordinate inverter, switchgear and cable routes with protected, ventilated technical space. The strongest choice is the one that remains coherent when planning feasibility, architectural quality, future maintenance and the total budget are considered together.
How to reach a robust decision
Allow for panel cleaning and inspection because dust and salt can reduce production. Check connection procedures, approvals and utility conditions before installation. The starting point is not selecting a catalogue solution. It is understanding how the subject relates to the plot, local rules and the way the home will actually be used.
Practical checklist
- Estimate annual demand and its hourly pattern before deciding array size and storage.
- Reserve an unshaded, accessible roof zone compatible with waterproofing and maintenance.
- Engineer fixings, ballast and support for site-specific wind loads.
- Choose components and connections suited to heat, dust and possible salt exposure.
- Assess batteries, load management and car charging against actual use rather than as automatic additions.
- Coordinate inverter, switchgear and cable routes with protected, ventilated technical space.
- Allow for panel cleaning and inspection because dust and salt can reduce production.
- Check connection procedures, approvals and utility conditions before installation.
Mistakes to avoid
- Sizing the system only by the available roof area.
- Penetrating a finished roof without coordination with waterproofing.
- Installing a large battery without analysing demand patterns.
Frequently asked questions
What is the first step?
