What are the differences between the MCS and Easy PV self-consumption calculations?
There are a few differences between the Easy PV and MCS self-consumption calculations:
| easy-pv.co.uk MCS | Easy PV | |
| Easy PV task |
Completed at the end of Performance task, select |
Completed in Consumption task, select |
| System size and consumption |
Strict limits:
|
No limits on system size or consumption. Any consumption, generation or battery capacity |
| Consumption profile | Domestic profiles only: home all day, home half the day and out all day |
Domestic or commercial consumption profiles. Plus the option to upload half-hourly data from customer |
| Method | Determines self-consumption based on look-up tables specified in MGD 003, using annual generation and consumption totals | Models how generation is distributed using PVGIS data, then calculates usage minute-by-minute across the entire year. |
| Additional options | Limited since it only compares annual figures and cannot factor in real-time changes. | Minute-by-minute calculation means export limits, inverter clipping, variable tariffs and forced charging/discharging of batteries are factored into calculations |
