 These solar hybrid power systems may be capable of providing a continuous source of power.Installers have the right to feed solar electricity into the public grid and hence receive a reasonable premium tariff per generated kWh reflecting the benefits of solar electricity to compensate for the current extra costs of PV electricity.An electrical power system containing a 10% contribution from PV stations would require a 2.5% increase in load frequency control (LFC) capacity over a conventional system - an issue which may be countered by using synchronverters in the DC/AC-circuit of the PV system.
