I'm trying to understand an efficiency curve from PVsyst, using this documentation
However, I'm not sure what this sentence means:
- This production is penalized by an ohmic loss$^1$ of the internal components (transformer and transistors), which increases quadratically$^2$ with power (like R · I²)$^3$. *
- What is meant by ohmic loss in this instance?
- When it mentions that it increases quadratically, does it mean in quadratic form (equation) i.e. $ax^2 + bx + c = 0$ and how does this relate to the efficiency curve of an inverter, relative to power loss?
- What does the equation represent, and what does it suggest when either parameter $R$ or $I^2$ is greater than the other?
