Free QuoteEfficient inverters maintain a power factor close to unity (1), which means that the real power output closely matches the apparent power output. The power factor change depending on solar radiation values in a grid-connected PV solar system is given in Table 3.
Fig. K70 – Example of electrical installation The power factor regulation through solar inverters can be implemented with power measurements at the photovoltaic installation and at the connection point to the grid, together with a control system that calculates and communicates the appropriate set point to the inverters.
Most grid connected PV inverters are only set up to inject power at unity power factor, meaning they only produce active power. In efect this reduces the power factor, as the grid is then supplying less active power, but the same amount of reactive power. Consider the situation in Figure 5.
Power factor changes depending on solar radiation values in a grid-connected PV solar system (from a solar power plant in the southeast of Turkey). The power factor is a significant factor in determining the quality of a grid-connected PV solar energy system.
There is therefore an incentive for these customers to improve the power factor of their loads and reduce the amount of reactive power they draw from the grid. Most grid connected PV inverters are only set up to inject power at unity power factor, meaning they only produce active power.
The power factor of a PV system is mostly determined by the efficiency of the inverter. Inverters are responsible for converting the DC electricity generated by the solar panels into AC electricity that can be supplied to the grid.
