Households often use a portion of the solar energy they generate and transmit the remains into the grid to receive a feed-in tariff. Higher rates of self-consumption result in faster payback times. Because grid electricity costs more than the feed-in tariff. Self-consume solar power is better than exporting it back which means sale back to the grid. You buy per unit of electricity much higher rate from the grid than exporting your solar electricity to the grid. In Sydney per unit electricity feed-in tariff will cost .25$ whereas when you export your produced electricity to the feed they give you, the name is just a price, only .05$. A small solar power system may have better self-consumption and a shorter payback time, but it will save less money on electricity overall. As a result, lowering the size of a system to achieve a faster payback period is typically a false economy that leaves you wishing you had installed a larger system from the start. Self-consumption varies by household, but those with 6.5 kilowatt solar systems utilize roughly 20% of the solar electricity generated on average, so I’ll use that statistic.
