I have a confusion weather the power injected into the grid for net metering purposes is real or reactive power. I have seen majority of notes that the voltages of the grid and inverter should be in phase and in that case the inverter transmits the reactive power only beacuse the real power gets to zero due to P=V1V2sin(delta)/X, where delta is zero when they

If all the homes have solar panel, and they dont have load at the moment, the voltage can increase above the grid''s limit, and some of the inverters will turn off. And the voltage will be the lowest at the transformer. Also, notice how it takes power to raise the grid''s voltage. Power, which comes from the solar panels.

In order to inject solar energy to grid you need to convert that to electrical energy which can be done by two ways via through solar thermal power generation and solar panels generation. Solar
For the “power boosting” mode, solar energy is injected into the steam bottom cycle to heat up the gas turbine exhaust, the live steam, the reheated steam, or the feedwater. The main idea is to keep fuel consumption constant, while the output power increases as a consequence of the incr ease in the steam flowrate (mas flowrate boosting) or
The DC power of the solar panels is converted into an AC power by inverters. These are transformerless and, besides generating AC current, also inject a small DC Current. Excessive DC current injection into an AC network can cause problems like transformer saturation, however, which will cause additional losses and reduce transformer lifetime.
