2800kW Solar PV System in Japan — Project Overview
The 2800kW solar PV system in Japan delivers utility‑scale on‑site generation for commercial users, with a $1,509,760 FOB price, $1,665,718 CIF delivery, and $4,029,760 turnkey EPC option. Configured as a 2800kW fixed‑tilt monocrystalline array at 36.2° tilt and 180° azimuth, it uses central inverters for grid‑tied operation.
For Japanese commercial and industrial facilities, this configuration offers a standardized large‑scale solution that can be deployed on suitable rooftops or ground‑mount land banks. According to IEA (2024), solar PV already accounts for more than 1,500TWh of global electricity, and Japan remains a mature market where grid‑parity projects are common for large consumers.
SOLAR TODO positions this 2800kW system as a repeatable, bankable configuration for factories, logistics centers, and large commercial campuses. The design is optimized for Japan’s mid‑latitude solar resource (around 36.2°N, 138.3°E), where fixed‑tilt arrays at near‑latitude angles typically provide stable annual yields with low mechanical complexity.
Technical Configuration and Design Approach
The customer’s configuration parameters define a clear, grid‑tied commercial system with no storage requirement and a focus on robust, proven components.
Core System Parameters
- Country: Japan (JP)
- Latitude / Longitude: 36.2 / 138.3
- Capacity: 2800kW (DC)
- Array type: Fixed
- Tilt angle: 36.2°
- Azimuth: 180° (true south)
- Module type: Monocrystalline
- Inverter type: Central
- Customer type: Commercial
- Need storage: No (pure grid‑tied)
According to NREL (2024), fixed‑tilt systems at or near site latitude typically maximize annual energy yield for grid‑tied plants without tracking, while maintaining lower CAPEX and OPEX than single‑axis trackers. The 36.2° tilt and 180° azimuth follow this best practice for the specified Japanese site.
Monocrystalline Module Selection
The system uses monocrystalline (mono) modules, aligned with global best practice for commercial and industrial (C&I) projects where land or roof area has value. Industry data from IRENA (2023) shows that modern mono modules commonly reach 20–22% efficiency, supporting compact layouts and reduced balance‑of‑system (BOS) costs per kW.
Key benefits of mono modules for this 2800kW system include:
- Higher energy density per square meter compared with older polycrystalline modules
- Better low‑irradiance performance, important for Japan’s variable weather
- Stronger bankability and warranty backing from Tier‑1 manufacturers
SOLAR TODO’s broader portfolio includes N‑Type TOPCon modules up to 24% efficiency, and similar technology is typically applied in large C&I projects to maximize yield over 25–30 years.
Fixed‑Tilt Array and Structural Design
A fixed‑tilt array is selected instead of tracking to prioritize simplicity and reliability. As IEA PVPS (2024) notes, fixed‑tilt remains the dominant configuration in many mature markets due to:
- Fewer moving parts and lower mechanical failure risk
- Simplified O&M and inspection routines
- Easier snow and wind load engineering in regions like central Japan
The 36.2° tilt is close to the site latitude, which generally optimizes annual production for grid‑tied systems. The 180° azimuth (true south in the northern hemisphere) maximizes midday output, aligning with typical Japanese commercial load peaks.
Central Inverter Architecture
The system uses central inverters, which are well‑suited to 2800kW‑class plants:
- Reduced inverter count compared with string‑based architectures
- Centralized maintenance and monitoring
- Lower per‑kW inverter CAPEX at utility and large C&I scales
IEEE 1547‑2018 defines interconnection and interoperability requirements for distributed energy resources with the grid; central inverters for this class of project are typically certified to meet such grid‑code requirements, including voltage ride‑through and reactive power support.
Electrical and Compliance Considerations
While the detailed single‑line diagram is not provided, a typical 2800kW Japanese commercial system would include:
- DC combiner boxes and protection devices sized for multiple module strings
- Central inverters with appropriate DC input range and AC output at local grid voltage
- Medium‑voltage step‑up transformer for connection to the facility or utility network
- Protection relays, metering, and communication interfaces
PV modules and inverters are generally expected to comply with:
- IEC 61215 for design qualification and type approval of crystalline silicon modules
- IEC 61730 for PV module safety
- Relevant grid‑code requirements and utility interconnection rules in Japan
Procurement and Pricing Structure
SOLAR TODO provides three clearly defined procurement options for this 2800kW project: FOB, CIF, and turnkey EPC. All prices below are verified and must be used verbatim.

Applications and Use Cases in Japan
This 2800kW configuration targets commercial and industrial customers in Japan who require large, predictable on‑site generation without storage.
Typical Commercial Applications
- Manufacturing plants with high daytime process loads
- Logistics hubs and distribution centers with large roof or adjacent land
- Data centers seeking partial on‑site renewable supply
- Large retail complexes and commercial campuses
According to IEA (2024), commercial and industrial consumers increasingly deploy on‑site solar to hedge against electricity price volatility and decarbonize operations. A 2800kW system can cover a substantial share of daytime consumption for many Japanese facilities.
Energy Strategy Without Storage
The customer configuration explicitly sets need_storage: false, indicating a pure grid‑tied design. This approach is appropriate when:
- The facility has stable grid access and no requirement for backup during outages
- Net metering or feed‑in arrangements are available or partial self‑consumption is sufficient
- The focus is on CAPEX efficiency and lowest possible LCOE
NREL (2024) highlights that grid‑tied systems without storage remain the lowest‑cost solar deployment model, with batteries added primarily where tariff structures or resilience needs justify the additional investment.
Expected Performance and ROI Context
The precise annual yield and ROI for this project depend on site‑specific irradiation, tariff structures, and consumption profiles, which are not included in the verified data and therefore are not quantified here. However, industry benchmarks provide context:
- IRENA (2023) reports global utility‑scale solar LCOE in the range of $0.029–$0.050/kWh in many markets.
- IEA states, “Solar PV has become the cheapest source of electricity in many regions,” especially for large‑scale projects.
Japanese commercial buyers can use tools such as NREL’s PVWatts or local simulation software, combined with the known 2800kW capacity and fixed‑tilt configuration, to estimate site‑specific energy yield and payback periods.
Comparison and Selection Guide
B2B decision‑makers evaluating this 2800kW system must choose between procurement models and ensure technical alignment with their facility’s needs.
FOB vs CIF vs Turnkey — Strategic Considerations
| Criterion | FOB $1,509,760 | CIF $1,665,718 | Turnkey $4,029,760 |
|---|---|---|---|
| International logistics | Buyer managed | Included to JP port | Included end‑to‑end |
| Local installation | Buyer/EPC | Buyer/EPC | Included (EPC by SOLAR TODO or partner) |
