Dennis Indutecc Posted September 25, 2018 Report Share Posted September 25, 2018 Valentine software, I have a question about the PVSol premium software package and specifically about the self-use of energy shown in the reports. In the Netherlands, 70-80 per cent of households have a 3-phase grid, as a result of which the load is also absorbed over 3-phases. Due to a change in subsidy rules, it will very soon become less profitable to return energy to the grid. In my calculations I therefore increasingly opt for a 3-phase inverter as the self-consumption is higher than in the case of a 1-phase inverter. However, I don't see it in the yield results. For example, I choose a standard load profile for an installation with a 2-person household of 4200kWh per year (divided over 3 phases). With a 5kWp on 1 and 3 phase inverter, the energy used by the company itself is, according to the report 31.3 and 31,6 %, almost the same, which does not seem to be true. In practice, the self-consumed energy of a 3-phase inverter will have to be significantly higher than that of a 1-phase inverter. Iff i make 2 reports with an installed capacity of 5400wp on a 1 and 3 phase inverter where the share of own used energy is almost as high, where in my opinion this is not true. Can you tell me why I get these results? yours sincerely Quote Link to comment Share on other sites More sharing options...
