Advantages of the solar energy
complementarities with traditional and other renewable energy sources,
flexibility (mobile, roof- or ground-mounted), environmental-friendly (no produces noise), little need of maintenance (PV system have
no move or rotate parts), lifetimes – up to 30 years.

Main applications of PV
Stand-alone (off-grid) Uses: remote region (remote wireless sensors,
small chargers, navigation lights, etc) or when on-grid connection is unnecessary.
Contains: storage battery and converter (DC-DC, DC-AC), maximum power point tracker (MPPT).
8
Main applications of PV
Grid-connected (on-grid) Uses: connected to local electricity network. Contains: converter (DC-AC), may not have
storage, maximum power point tracker (MPPT).
Fed-in tariff (0.2…0.48 €/kWh, biggest tariff in the world – 0.48 €/kWh in Ukraine).
