Solar panel installation in Helmdange: 20 panels and a complete Enphase ecosystem
This home has several roof sections, each with room for only a few panels, as well as shaded areas. Ecoclima therefore designed a system comprising 20 AIKO Neostar panels with Enphase IQ8HC microinverters, two IQ Battery 5P units with FlexPhase — 10 kWh in total — and an IQ EV Charger 2 integrated into the solar energy management system.

The project challenge
Several small roof sections and shading: a configuration where microinverters make a real difference.
The roof does not form one large, uniform plane. The 20 panels had to be distributed across different sections with varying orientations and solar exposure.
A section-by-section assessment
Our technicians assessed every usable area, the shadows cast throughout the day and how the modules could be distributed without treating the roof as a uniform surface. This layout makes effective use of the different available sections of the home.
Each AIKO Neostar panel is paired with an Enphase IQ8HC microinverter. Conversion therefore takes place at module level: when one area is temporarily shaded or less favourably exposed, the effect remains largely limited to the affected panel instead of determining the behaviour of an entire string.
Microinverters do not eliminate shading. They do, however, allow each panel to be managed and monitored individually, directly addressing the constraints of this roof.
- 20 panels distributed across several roof sections.
- Different orientations and shaded areas taken into account.
- Production and monitoring managed at panel level.
The Enphase ecosystem in pictures
From storage to smart control: an energy system designed as one coherent whole.
Beyond the rooftop panels, the project includes equipment that measures, stores and directs solar energy according to the household’s needs.
Installed configuration
A complete Enphase ecosystem, from the rooftop to EV charging.
The panels, microinverters, metering gateway, batteries and EV charger operate within one home energy management strategy.
Solar production
AIKO Neostar panels
20 panelsThe modules were distributed across the usable roof sections, taking their orientations and shaded areas into account.
Panel-level conversion
Enphase IQ8HC microinverters
Individual managementInstalled beneath each module, the IQ8HC converts the electricity locally. This architecture is particularly relevant when panels are distributed across several roof sections or exposed differently to shading.
Metering and control
Enphase IQ Gateway Metered
Production + consumptionThe gateway collects system data and measures energy flows. It gives the homeowner a centralised view of what the home produces and consumes.
Energy storage
2 × IQ Battery 5P with FlexPhase
10 kWh in totalEach battery provides 5 kWh of usable capacity. The two units were sized together according to the customer’s actual needs, without oversizing the storage system.
Smart charging
Enphase IQ EV Charger 2
Integrated solar chargingThe charger can prioritise available surplus solar energy when charging the vehicle, helping to increase the household’s self-consumption.
Why deploy the complete ecosystem?
The intelligent home energy management system — or HEMS — connects production and consumption data with the batteries and EV charger. The aim is not simply to add more equipment, but to make better use of solar energy when it is available, store part of the surplus and integrate EV charging into the same strategy.
Local expertise
An Ecoclima solar installation in Helmdange, designed around the building and how energy is used.
A home with several roof sections cannot be approached like one large, unobstructed plane. For this project, we first assessed the building’s actual configuration before selecting the electrical architecture, storage capacity and method of integrating EV charging.
A layout tailored to each roof section
The 20 panels are distributed according to the available space, orientations and exposure to shading.
An architecture suited to a complex roof
Microinverters enable panel-level conversion and monitoring.
Storage sized according to actual needs
Two 5 kWh batteries were selected to provide 10 kWh in total.
EV charging integrated into the solar strategy
The charger can prioritise available surplus energy to maximise self-consumption.
Project result
20 panels intelligently distributed across the available roof sections.
The completed system makes use of the roof’s actual potential while bringing production, monitoring, storage and EV charging together within one energy ecosystem.
Questions about this project
Solar panel installation with Enphase microinverters: FAQ
Why are microinverters particularly well suited to this home in Helmdange?
The panels are distributed across several roof sections, and some areas are affected by shading. With an Enphase IQ8HC microinverter paired with each module, conversion and monitoring take place panel by panel rather than depending on a single uniform string.
Do microinverters eliminate losses caused by shading?
No. No equipment can generate solar energy that shading prevents from reaching a panel. The benefit of microinverters is that the impact remains largely limited to the affected module, while the other panels continue to operate according to their own exposure conditions.
What equipment was installed for this project?
The installation comprises 20 AIKO Neostar panels, Enphase IQ8HC microinverters, an IQ Gateway Metered, two IQ Battery 5P units with FlexPhase providing 10 kWh in total, and an Enphase IQ EV Charger 2.
Why were two 5 kWh batteries installed?
Together, the two IQ Battery 5P units with FlexPhase provide 10 kWh of usable capacity. This capacity was selected according to the customer’s needs and usage patterns; it is not a standard size applicable to every home.
Can the IQ EV Charger 2 use surplus solar energy directly?
Yes. As part of the Enphase ecosystem, the charger can prioritise available surplus photovoltaic energy for charging. The share actually supplied by solar nevertheless depends on current production, household consumption and the selected settings.
What is the role of the Enphase IQ Gateway Metered?
The gateway centralises system data and measures photovoltaic production as well as household consumption. It provides the information required to monitor and coordinate the Enphase equipment.
Does your roof have several orientations or shaded areas?
Ecoclima assesses every available roof section, your consumption profile and future needs to design a solar installation suited to your home in Luxembourg.
