22 Solar Panels in San Roque, Cádiz

With an annual electricity bill of €5,711.70, the client was spending well above average for a residential property – and wanted a system that would make a meaningful, long-term reduction to that cost. The villa’s size, pool, and year-round occupancy all pointed to a system capable of generating substantial daytime output consistently across every month of the year.

For clients in this part of Cádiz, we regularly see strong results – you can browse our installations in San Roque to see the kind of savings achievable in this area. As with every project we take on, the process started with a free solar survey – an on-site visit combined with drone analysis, shading assessment, and a tailored energy model built around the specific characteristics of the property.

The survey was carried out by Alan Manning, whose energy assessment took into account:

• A multi-pitch roof with panels distributed across two main roof sections at differing orientations
• Significant mature tree cover surrounding the property, including tall palms directly adjacent to the building
• An annual electricity spend of €5,711.70 – well above average for a residential property of this type
• The client’s requirement for a system sized to deliver substantial savings across all seasons

The roof layout was the defining challenge. With no single dominant south-facing aspect and mature vegetation casting variable shade at different times of day, a standard string configuration would have allowed the weakest-performing panels to limit output across the whole array. As with our 33-panel installation in Sotogrande – where the client similarly wanted to reduce high monthly bills and ensure reliable performance – power optimisers were specified from the outset, allowing each of the 22 panels to operate independently. The proposal projected annual savings of €1,867.94, bringing the average monthly bill down from €475.97 to €320.31.
