About the Project
The client wanted a solar installation to reduce their electricity bills while keeping the clean aesthetic of their villa intact. Marblanc Solar installed an 8kW solar energy system, which will also reduce electricity costs by over €1,200 a year.
Background
Located in the peaceful mountain surroundings of Istan, the client’s villa was facing rising energy costs throughout the year. They contacted Marblanc Solar for professional advice on the most discreet and effective solar setup.
Marblanc Solar has completed numerous solar installations Marbella, and this the first of our solar installations in Istan. The client requested a free solar survey, which includes a full on-site visit, drone imaging, shading assessment, and a customised proposal outlining the expected production and return on investment.
Our solar survey engineer confirmed that the client’s average annual electricity bill was €3,252 — roughly €271 per month.
However, the client asked that no panels be installed on the villa’s tiled roofs, as they wanted to preserve the property’s appearance. Instead, our team designed a layout to fit all 14 JA Solar 595W panels neatly on the flat garage roof, ensuring both efficiency and visual harmony.
This configuration limited the available roof space and therefore the potential total generation.
But the system still achieves 37% annual savings and is expected to break even within 8–9 years. Thanks to Marblanc Solar’s 30-year workmanship warranty, the installation is projected to pay for itself several times over while maintaining the villa’s aesthetic integrity.
Equipment Installed
- 14 × JA Solar 595W solar panels
- 1 × Huawei 8kW solar inverter
Solution
Our team installed a high-performance 8kW system using 14 JA Solar 595W panels. The installation was configured entirely on the property’s flat garage roof, optimising the available space without altering the villa’s visible roofline.
The project was completed in just two days. All cabling was hidden, and the panels were secured on a non-penetrative mounting system to protect the waterproofing and ensure the villa’s tiled roof remained untouched.
As part of our post-installation support, we then secured an exclusive solar feed-in tariff with a virtual battery.
We also monitored the client’s electricity usage every day for two weeks to help optimise their appliance usage with plug timers and use of our solar app. Finally, we assigned the client to one of our Monday-Sunday WhatsApp aftercare groups, should they have any questions.
Results
The client was very happy with the final installation, which achieved the desired savings while completely preserving the property’s aesthetics.
