Penthouse Solar - Puerto Banús
Luxury ducted HVAC in a Puerto Banús beachfront penthouse — concealed ceiling cassettes providing heating and cooling across 280m² with fan coil units rated below 28dB(A).
By Ben Hayden
Project Overview
The Challenge
The Puerto Banús penthouse — a 220m² rooftop duplex with 180° sea views and a private pool — had two specific solar installation constraints. First, the building's premium architectural profile meant the community of owners had passed a resolution prohibiting any visible rooftop structures from the street level, including solar panels. Second, the penthouse's substantial self-shading from the upper terrace level and neighbouring PB tower meant a conventional south-facing array would produce well below projections. We needed to design a system that was invisible from street level, undetectable to the community, and genuinely productive despite the shading constraints.
The Solution
Discreet 6kW solar installation for luxury penthouse. Premium black panels blend seamlessly with modern architecture.
Technical Specifications
- 12 x 500W SunPower Maxeon 3 black panels
- SolarEdge SE6000H HD-Wave inverter
- Power optimizers on each panel
- Premium all-black aesthetic
- Smart energy monitoring
Our Installation Process
Shading Analysis & Orientation Optimisation
We used the Solargis shademap tool and on-site measurements to model annual irradiance at all available panel positions on the terrace. The south-facing positions suffered 35-45% shading losses from the upper level and adjacent tower. East and west-facing positions on the terrace perimeter walls — invisible from street level — received 15-20% less irradiance than optimal south, but with minimal shading losses. The performance difference favoured the perimeter wall positions.
Low-Profile Panel Mounting System
Panels were mounted flush with the existing terrace parapet walls using custom powder-coated aluminium brackets — the panel surface barely extends above the existing wall height, making them genuinely invisible from the street and from neighbouring properties at the same level. The community administrator was notified in writing as required, with photographs confirming no visual impact from street level.
Micro-Inverter System for Shading Resilience
Each panel was fitted with an individual Enphase IQ8 microinverter rather than a conventional string inverter. In a split east/west orientation with different sun angles throughout the day, microinverters ensure each panel operates at its individual maximum power point — panels in shade don't reduce output from panels in sun. The Enphase Enlighten monitoring platform provides individual panel performance data, enabling immediate identification of any underperforming panel.
Community Approval, Boletín Eléctrico & Enphase Enlighten Handover
The installation on a penthouse terrace within a community of owners required written notification to the community administrator under Article 17.5 Ley de Propiedad Horizontal. Photographs showing the panels sitting below the penthouse parapet line (invisible from street level) were included with the notification — a key point of contention in penthouse solar installations in Puerto Banús where visual impact on the building's premium appearance is scrutinised. The Boletín Eléctrico covering the new solar circuit and consumer unit modifications was submitted to the Delegación de Industria on the day of commissioning. The CAU number was issued by Endesa within 12 days. The Enphase Enlighten app was configured on the owner's device with panel-level monitoring enabled, and the IQ Gateway was tested for connectivity from both the Spanish mobile number and the property's Wi-Fi — ensuring monitoring remains active during the extended periods when the property is unoccupied.

Estimate solar yield for the actual site
Annual generation depends on location, orientation, tilt, shading and system losses. An irradiance figure is not a guaranteed yield per installed kilowatt. State the assumptions and compare the estimate with the property's consumption.
European Commission — PVGIS ↗Check the applicable self-consumption arrangement
RD 244/2019 regulates administrative, technical and economic conditions for self-consumption. Export compensation is subject to the applicable arrangement and contract; exported energy is not automatically valued at the retail import price.
BOE — RD 244/2019 ↗Tax relief needs separate eligibility checks
Do not assume solar qualifies for an income-tax deduction or a standard municipal IBI discount. Check current AEAT conditions and the property's municipal ordinance, required evidence, dates and application process before including an incentive in a budget.
