FAQ

What's self-consumption rate?

The percentage of solar energy you use directly vs. export to grid. Higher rates = better savings.

How do I find peak sun hours?

It varies by location. Use solar calculators or local data. US averages 4-6 hours; Australia 4-7 hours.

What about battery storage?

Batteries increase self-consumption but add cost. They make sense when feed-in rates are low or for backup power.
