Is a Corporate Solar Farm an Investment or a Cost?
The costs of constructing a solar farm are primarily distributed across initial construction and subsequent maintenance. At the same time, revenues are derived from multiple dimensions, including electricity savings from power generation, peak-valley arbitrage, policy subsidies, and carbon credit trading.

Take a 1 MW commercial and industrial project as an example:
Investment: Initial construction costs approximately ¥2 million.
Power Generation: Annual power generation can reach 1.1 million kWh. Assuming 90% is self-generated and self-consumed, each kilowatt-hour saves 0.7 yuan compared to grid electricity rates, resulting in annual electricity cost savings of approximately 690,000 yuan.
Additional Revenue: Through energy storage for peak-valley arbitrage, an additional ¥100,000–150,000 can be generated annually. Carbon emission reduction trading contributes roughly ¥50,000 per year.

The payback period for solar farms typically ranges from 3 to 5 years, after which a net profit period exceeding 20 years will generate sustained positive cash flow for enterprises.
What are the key benefits of installing solar for companies?
- Save on Electricity Costs
Electricity expenses constitute the largest portion of a company's operating costs. Installing a solar system enables “self-generation for self-consumption,” thereby reducing electricity costs.

- Stable Returns
The lifespan of a solar farm extends to approximately 20-25 years. After the investment payback period, enterprises can enjoy the benefits generated by the solar farm, achieving long-term stable returns.

- Policy Support
Many countries provide support for distributed solar projects through financial subsidies, tax breaks, and loan interest subsidies. - Utilizing Idle Resources
The emergence of rooftop solar systems has successfully broken the deadlock of land resource scarcity while providing a degree of protection for roofs, thereby extending their service life.

For businesses, solar systems not only reduce operational costs but also serve as revenue-generating assets—a stable, long-term investment.
