If a PV array has a rated DC capacity of 12kW and the inverter has an AC rated output of 10kW, the DC/AC ratio would be 1.2. What Is the Ideal DC/AC Ratio? In most cases, the ideal DC/AC ratio typically ranges between 1.2 and 1.4. However, the optimal value can vary based on local climate conditions, equipment costs, and specific project goals.
To maximize a solar project’s value, it can be advantageous to oversize the array relative to the inverter rating to increase system output in partial production conditions. We use the term inverter loading ratio (ILR) to describe this ratio of the array’s nameplate DC power rating to the inverter’s peak AC output rating.
This result suggests that systems with higher ILRs could yield more predictable generation patterns or at least more frequent expectation of full output during mid-day hours, with a much higher share of that time spent at maximum output.

DC/AC ratio and inverter loading shape real solar yield more than most design choices. Set them well and you gain energy all year, keep the inverter in its high-efficiency zone, and leave headroom for grid support and batteries. This piece focuses on practical math, climate effects, and sizing ranges you can use today.
