About the Project
The client wanted a solar installation that would allow them to add a battery to their existing system. Marblanc Solar rewired and upgraded to a 4.485kW solar energy system and integrated the battery.
Background
In this case, the client already had a small solar system but wanted to take the next step by storing excess production with a solar battery.
Marblanc Solar has completed many solar installations in Mijas, and the client requested our free solar survey. This includes a site visit, a drone flight to assess roof areas, a detailed shading analysis, and finally a proposal tailored to the property.
During the home visit, our survey engineer discovered that the client’s previous installation had been carried out by a subcontractor of a large electricity company and was poorly executed.
The poor state of the old installation meant a redesign was needed: new inverter, new cabling, and the addition of three extra panels to maximise production.
This combination ensured strong performance, fast return on investment, and peace of mind that the system was built to last.
Equipment Installed
- 3 × JaSolar 595W solar panels
- 1 × Huawei 5KTL hybrid inverter
- 1 × Huawei LUNA2000-5-S0 solar battery (5kWh / 5kWh usable)
Solution
Our team designed and installed a 4.485kW hybrid solar system. The installation connected seamlessly with the client’s existing panels, while three additional panels were added across available roof space to boost generation.
The key challenge was overcoming the limitations of the client’s old system. By replacing the grid inverter with a hybrid Huawei inverter, we were able to integrate the solar battery without issue. The new wiring, protections, and installation ensured safety and long-term reliability.
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: their system now produces enough to fully cover their needs, with the battery providing energy security at night. Thanks to the virtual battery arrangement, they are also earning about €8 per month in electricity credit.
