Making a home energy neutral.

Challenge: multi-sided roof and shading

The house is located in a wooded area and has a multi-sided roof with four sections, each with a different orientation and sunlight exposure. At the same time, Ron wanted to stay within a standard residential grid connection. A heavier connection would increase fixed costs, so the system needed to perform optimally within the existing capacity.

Bozon Eindhoven therefore started with measurements before designing the system:

• How does the sun move around the house?

• Where does structural shading occur?

• What does that mean for annual yield?

Based on this, 37 solar panels of 415 Wp were installed, distributed across all four roof sections.

“What stands out to me is that even the north-facing side still delivers a solid yield. I didn’t expect that.”

Taylor panels use Nano Optimizers that optimise per one-sixth of a panel. If part of the panel is shaded or soiled, the rest continues to produce. In this situation with significant shading, that makes a clear difference in output.

Solar and battery as a logical next step

With the phase-out of net metering, the focus shifts from feeding back to self-consumption. That is why Ron chose to expand the system with a home battery.

A 14.7 kWh Taylor battery was installed. Large enough for storage, but precisely matched to the household’s actual consumption. A backup power setup was also included. In case of a power outage, lighting, refrigerator and freezer remain operational.

“It gives peace of mind to have energy available when needed.”

Dynamic energy contract and automated control

Ron opted for a dynamic energy contract with Frank Energie, where electricity prices change hourly.

• High supply from solar and wind means lower prices

• High demand or limited supply means higher prices

The battery automatically responds:

• When electricity is cheap, the battery charges

• When electricity is expensive, stored energy is used or fed back

Ron does not need to manage this manually. The system settings define the strategy, with priority given to the heat pump and electric vehicle. This makes the system predictable in use. On average, it generates around €50 to €60 per month.

The battery system has been operational since September 2025.

• In 2025, consumption was 4150 kWh and 1608 kWh was fed back.

• In 2026 up to mid-February, consumption was 1927 kWh and 664 kWh was fed back.

The result is an A++++ energy label. The home is energy-neutral, exactly as intended from the beginning.

Why Bozon Eindhoven?

Ron requested multiple quotations in the past. Bozon stood out with clear, technically substantiated advice and committed aftercare, even after project completion.

“The way Sebastiaan explained it and the reasoning behind his choices felt well thought out.”

In this new-build project, all cabling could be fully concealed. For the battery, practical considerations were also made regarding what is essential during a power outage.

Why Taylor?

Ron studied mechanical engineering at TU Eindhoven and worked nearly forty years in thermal engineering. He evaluates technology critically. Bozon works with Taylor.

Taylor stood out to him because of:

• Optimisation per one-sixth of a panel

• A DC architecture from panel to battery

• One integrated system

He also valued that Taylor’s technical foundation was partly developed from TU Eindhoven. This academic background aligns with his own experience.
