As discussed previously, owners of solar panels have a choice to make:
- Maximise the total amount of power generated over the whole day; or
- Maximise the amount of energy generated when it is most needed, during the peak demand time.
Unless the peak demand time is midday (and it generally isn’t), you can’t do both.
The problem of matching peak output to peak demand haunts most green energy systems: Wind farms only generate power when the wind is blowing; Wave generators only generate power when the sea is wavy; the power source of geothermal energy is constant throughout the day and night.
The answer is batteries – generate the power whenever you can, store the power in batteries and feed it into the main power supply at peak demand times.
According to The Financial Times the prospects for Grid Scale Storage are promising. Grid scale storage is designed for…
