We cut a client's electricity costs by nearly €1,008 a year after installing 9 solar panels on their villa in Hondón de los Frailes, Alicante.
A client in Hondón de los Frailes, Alicante asked Marblanc Solar to design a solar system for their detached rural villa – a property with two pools, a covered outbuilding, and a hip-roofed main house set in open inland scrubland. We installed 9 × 600W panels on the south-facing pitch, delivering a 5.4kWp system projected to cut their annual electricity bill by 79%, saving approximately €1,008 per year.
For a property this size – a spacious rural villa with two pools and the energy demands that come with them – an annual electricity bill of €1,267.70 is not unusual, but it was a cost the client was ready to address. The combination of high summer consumption, an inland Alicante location with excellent solar irradiance, and a clear south-facing roof made solar an obvious fit.
We carry out installations across Alicante regularly, and this property shared several characteristics with jobs we’ve completed elsewhere in the province. The client arranged a free solar survey – an on-site visit that included a drone analysis of the roof, a detailed shading assessment, a review of historical consumption data, and a full system simulation to size the installation correctly.
Miguel Ángel Ruiz Zapardiel led the energy assessment, which took into account:
That last point shaped the proposal in a meaningful way. Rather than a standard string inverter, the system was designed around a Deye hybrid inverter – battery-ready from day one, so storage can be added later without replacing the core equipment. The projected figures made the case clearly: annual savings of €1,007.63, with the monthly bill dropping from €105.64 to €21.67.
Our team installed all 9 panels on the south-facing pitch of the villa’s hip roof – the one face with a clear, unobstructed solar aspect. The hip roof geometry naturally limits usable area on each face, so the 3×3 panel arrangement was positioned to make the most of the available pitch while keeping the layout clean and structurally balanced. The Deye hybrid inverter was installed and configured to integrate with the home’s existing electrical system, with monitoring set up so the client can track generation and consumption in real time.
All cabling was fully concealed within the existing roof and wall structure, routed cleanly out of sight from both inside and outside the property. The Sunfer Microrail mounting system was fixed with high-grade chemical resin and waterproof membranes, preserving the integrity of the terracotta tiled roof and ensuring a weather-resistant, long-term finish.
After installation, our engineers secured a feed-in tariff with virtual battery, allowing surplus generation to be credited against future bills. Over the following two weeks, we monitored daily electricity usage, adjusted plug timer settings to maximise solar self-consumption, and set up the client on the solar monitoring app. Ongoing support continues through our seven-day WhatsApp aftersales care group.
Our Free Solar Survey includes: home visit, drone inspection, 3D performance model, two custom proposals and break-even estimations.
