I know how a consequential model works with regards to multi-functional processes.
For example, when an incineration process produce heat (as a co-product), the consequential model will consider the heat as a negative input, so that the burden will be avoided.
However, what about a single-output process?
For example, photovoltaic electricity production in which the only output is 1 kWh of electricity.
How the consequential approach (for example the consequential version of ecoinvent) is considered here?
