Solar power is rated a little differently, but again its rating is its electrical output under optimum conditions, so a 1 GW plant (with 20% efficient solar cells) is intercepting 5GW of sunlight and producing 1 GW of power. That means, 200GW capacity will produce 200GWh in one really good hour.
It's important to note what this means: In order for an inverter to put out the rated amount of power, it will need to have a power input that exceeds the output. For example, an inverter with a rated output power of 5,000 W and a peak efficiency of 95% requires an input power of 5,263 W to operate at full power.
One gigawatt-hour (GWh) is equal to 1 million kWh. So, a power plant with a capacity of 1 GW could power approximately 876,000 households for one year if they collectively consume 10,000 kWh each, assuming the plant operates continuously throughout the year.
Some or all of the specifications usually appear on the inverter data sheet. Maximum AC output power This is the maximum power the inverter can supply to a load on a steady basis at a specified output voltage. The value is expressed in watts or kilowatts. Peak output power
