Hongjiali New Energy (HG POWER) Investment Cost Analysis of Solar-Storage-EV Charging Integrated Stations

October 13, 2025

Solar-storage-charging integrated stations are becoming a core component of the global clean-energy and intelligent transportation ecosystem. For investors, developers, and charging-station operators, understanding the true investment cost, cost structure, and key influencing factors is essential for making profitable decisions.

This guide by Hongjiali New Energy (HG POWER) provides a complete, cost analysis for solar-storage-charging integrated stations, covering cost breakdowns, project-scale case studies, and strategies to reduce CAPEX.

What Is a Solar-Storage-Charging Integrated Station?

A solar-storage-charging integrated station combines:

Solar PV power generation
Battery energy storage systems (BESS)
EV DC fast chargers and AC slow chargers

This configuration significantly reduces operating costs (electricity purchase), improves charging-station energy autonomy, and avoids expensive grid upgrades.

Investment Cost Structure of Solar-Storage-Charging Stations

Below is the standardized cost breakdown, based on typical market pricing and Hongjiali New Energy’s (HG POWER) project experience.

1.1 Photovoltaic (PV) System Costs

1.4 Civil Engineering & Power Distribution

Includes:

Land leasing or land purchase
Transformer upgrades
Cable trenches and foundations
Safety and fire systems
Canopies and site facilities

Cost Range: 300,000 to 1,500,000+ yuan depending on location and grid capacity.

1.5 Design & System Software

Engineering design
Surveys & permitting
Energy Management System (EMS)

Cost Range: 100,000–300,000 yuan

Scenario 1: Medium-Small Station

Configuration

PV: 100 kW
Energy Storage: 200 kWh / 100 kW
Chargers: 2×120kW DC + 4×7kW AC

Total Investment Breakdown

Component	Cost
PV System	450,000 yuan
Energy Storage	300,000 yuan
Chargers	120,000 yuan
Civil & Power Distribution	300,000 yuan
Design & EMS	150,000 yuan

Estimated Total Investment:

≈ 1.32 million yuan

Typical Range: 1.3–1.8 million yuan

Scenario 2: Large Comprehensive Station

Configuration

PV: 500 kW
Energy Storage: 1 MWh / 500 kW
Chargers: 6×160kW DC + 2×240kW DC + 10×AC slow chargers

Total Investment Breakdown

Component	Cost
PV System	2,000,000 yuan
Energy Storage	1,400,000 yuan
Chargers	710,000 yuan
Civil & Grid Upgrades	1,500,000 yuan
Design & EMS	250,000 yuan

Estimated Total Investment:

≈ 5.86 million yuan

Typical Range: 5–7 million yuan

Key Factors Influencing Investment Costs

1. Energy Storage Prices

LFP battery prices fluctuate the most, directly impacting CAPEX.

2. Power Grid Capacity

If grid upgrades are required, costs may increase by millions.

3. Charging Equipment Selection

Domestic vs imported brands create large price differences.

4. Land Costs

Urban, suburban, leased, or self-owned land dramatically affects TCO.

5. Technology Configuration

Fast charging vs ultra-fast charging significantly alters charger cost.

How to Reduce Investment Cost (CAPEX)

Strategies recommended by Hongjiali New Energy (HG POWER):

1. Utilize Government Policy Incentives

Apply for:

Charging infrastructure subsidies
PV and energy-storage construction incentives

2. EPC/Third-Party Investment Model

Let investors finance the system and share revenue, reducing your upfront cost.

3. Phased Construction

Start with chargers → add PV → add energy storage.

4. Optimize Design

Use intelligent EMS to avoid oversizing PV or energy storage.

How Much Does a Solar-Storage-Charging Integrated Station Cost?

Station Scale	Investment Range
Medium-Small Station	1.3–1.8 million yuan
Large Commercial Station	5–7 million yuan
Extra-Large Stations	Up to 10+ million yuan

Before investing, Hongjiali New Energy (HG POWER) recommends:

Detailed site inspection
Load analysis
Electricity price modeling
Comprehensive financial evaluation

This ensures the system is both technically optimal and financially profitable.
