Japanese Villa Solar Roof Project

Project Overview

This 25kW residential rooftop project in Japan uses GreenMore triple-arch Hantile solar tiles as the BIPV roofing system, paired with a GM-HW15K 16kW three-phase solar inverter and four GM-ESS-B100S16 5kWh batteries (20kWh total) connected in parallel. The system operates in self-generation and self-use mode, storing surplus solar energy for evening consumption.

Japanese villas demand high standards for both aesthetics and engineering. The Hantile triple-arch profile blends with traditional Japanese roof lines while generating clean electricity. For distributors and installers serving Japan's premium residential market, GreenMore delivers a single-source BIPV solution — tiles, three-phase inverter, and modular batteries — with full technical support.

System Configuration

Project Highlights

• Triple-Arch for Japanese Aesthetics

The Hantile triple-arch design complements traditional Japanese villa roofing. Homeowners get a seamless look that preserves architectural character — while the tiles generate clean energy from every square meter of roof.

• 20kWh Modular Battery Array

Four 5kWh GM-ESS-B100S16 batteries in parallel provide 20kWh of storage. The modular design means individual units can be serviced or replaced without taking the entire system offline — important for Japan's high reliability expectations.

• Three-Phase Power for Villa Loads

The GM-HW15K three-phase inverter handles the balanced power demands of a Japanese villa — air conditioning, kitchen appliances, heating, and EV charger — without single-phase bottlenecks.

• Seasonal Adaptability

Japan experiences four distinct seasons — from snowy winters to humid summers. GreenMore Hantile tiles are rated for freeze-thaw cycles, typhoon-grade wind loads, and high UV conditions, ensuring year-round performance.

FAQ

Q1: How does the system handle Japan's winter snowfall?

A: GreenMore Hantile tiles are rated for 5,400 Pa mechanical load and tested for freeze-thaw cycles. Snow slides off the curved surface naturally, and the 20kWh battery ensures continued power supply during low-generation periods.

Q2: Can the three-phase inverter support grid-tied export?

A: Yes. The GM-HW15K supports both grid-tied export and self-consumption modes. Surplus solar generation can be fed back to the grid where local regulations allow.

Q3: Does GreenMore offer OEM customization for the Japanese market?

A: Yes. GreenMore provides OEM customization for tile dimensions, colors, and electrical specifications to match Japanese building codes and architectural preferences. We work directly with local distributors and installers.

Safety & Compliance

• Typhoon-Grade Wind Resistance: Hantile tiles withstand high wind loads common during Japan's typhoon season, with secure mechanical fastening to the roof structure.
• Freeze-Thaw Durability: Tiles maintain structural integrity through repeated freeze-thaw cycles in northern Japanese winters.
• International Certifications: Products comply with EN 14782, EN 1090-1, ISO 9001, ISO 14001, CE, IEC 62619, MSDS, and UN38.3.
