Solar Photovoltaic (PV) systems are designed to create electricity. The amount of electricity created will depend on many variants, the main ones being shading, orientation, angle of modules etc.
Electricity is produced from sun light in the form of a DC current, which is then converted into an AC current via the inverter, which is useable within your current electricity system. This electricity is then fed back into the distribution board and used within your building. This will reduce the energy used from the national grid thus reducing fuel bills and CO2 emission. Any surplus electricity will be fed back into the national grid (exported).
The electricity created by the PV system will be monitored and a reading will be available from the energy meter, this measurement is in kilowatt-hours (kWh).
Once the system has been fully commissioned electricity will be produced automatically. The system can be checked for correct operation by monitoring the lights displayed on the inverter (see O&M manual upon completion).
