What is PV module capacity & solar inverter capacity ratio?
The PV module capacity and solar inverter capacity ratio are commonly referred to as capacity ratio. Reasonable capacity ratio design needs to be considered comprehensively in the light of the specific project.
What is a good DC/AC ratio for a solar inverter?
Because the PV array rarely produces power to its STC capacity, it is common practice and often economically advantageous to size the inverter to be less than the PV array. This ratio of PV to inverter power is measured as the DC/AC ratio. A healthy design will typically have a DC/AC ratio of 1.25.
Is there a difference between inverter size and solar panel capacity?
However, this should always be within the recommended ratio. This is the reason why you may see a ‘mismatch’ between inverter size and solar panel capacity – for example, a 6.6kW system advertised with a 5kW inverter.
What is a good DC/AC ratio for a PV system?
A 1:0.8 ratio (or 1.25 ratio) is the sweet spot for minimizing potential losses and improving efficiency. DC/AC ratio refers to the output capacity of a PV system compared to the processing capacity of an inverter. It’s logical to assume a 9 kWh PV system should be paired with a 9 kWh inverter (a 1:1 ratio, or 1 ratio).
Why is there a'mismatch' between inverter size and solar panel capacity?
This is the reason why you may see a ‘mismatch’ between inverter size and solar panel capacity – for example, a 6.6kW system advertised with a 5kW inverter. It’s critical for an oversized system to remain within the correct ratio, as this not only impacts efficiency, but also your eligibility for government solar incentives.
How do I calculate a solar panel inverter ratio?
To calculate, divide your solar panel system’s total DC rating by the desired inverter’s AC output. This gives you the array-to-inverter ratio: For example: Within the ideal range (up to 1.33) set by many regulatory bodies, like Australia’s Clean Energy Council.
