Your old DB board can stop a solar CoC before it starts
A solar CoC covers the whole installation, not just the new panels. Learn how to separate remedial DB board work from the solar quote and who must certify it.
How to use monitoring data to prove a solar warranty claim
Baseline your solar system's yield, export monitoring data you actually own, and turn a declining trend into evidence a warranty assessor will take seriously.

Will a battery actually raise your self-consumption?
A battery only lifts self-consumption when it shifts solar into the evening, not when it sits full for load shedding. How to check the real number on your own meter.
