About the Project
The client wanted a solar installation to bring down the cost of their high monthly electricity bills while making the property more energy efficient. Marblanc Solar installed a 6.88kW solar energy system, which will also reduce electricity costs by over €2102 a year.
Background
El Rosario is a prestigious residential neighbourhood in Marbella, and like many homeowners in the area, this client was motivated to go solar to lower their reliance on costly grid electricity. Rising bills were becoming a concern, and solar offered a clear path to savings while improving the property’s sustainability.
Marblanc Solar has completed many solar installations in Marbella, making us a trusted choice in the region. As always, the project began with a free solar survey, where we visited the villa, carried out a drone roof inspection, assessed shading factors, and prepared a tailored proposal for the client.
Our solar survey engineer provided a full breakdown of the client’s previous consumption, which revealed annual bills of around €3,932 — averaging €328 per month.
The client’s request was to use all black panels for aesthetic reasons, even though these panels provide a slightly lower output compared to our standard models. They also asked us not to cover every available roof section, prioritising the look of the villa from the road and garden.
This meant designing a system that would deliver around 50% savings while preserving the property’s visual appeal.
Equipment Installed
- 16 × JaSolar 430W all black solar panels
- 1x Huawei 10KTL solar inverter
- 1× Huawei LUNA2000-7-S1 battery (6.9kWh / 6.9kWh usable)
Solution
Our team installed a 6.88kW solar energy system across selected roof areas of the villa, ensuring the panels were positioned for both performance and discretion. The combination of panels, inverter, and battery storage meant the client could generate and store a significant share of their own electricity.
The installation required careful placement to keep the panels hidden from the main views of the property.
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 delighted with the outcome, appreciating the balance between strong bill savings and the preservation of their villa’s aesthetics. Even with fewer panels than usual, the system still cut their annual energy costs by over €2,100, making them happy with both the performance and the service provided by Marblanc Solar.
