Costs & Savings

Start here before treating any savings number as final. These pages explain simple payback, export credits, utility rates, incentives, financing, maintenance, and common missing costs such as roof work, panel upgrades, inverter replacement, and battery aging.

Questions this section helps answer

Which costs are often left out?
How should export credits and time-of-use rates be modeled?
Which incentives need direct confirmation?
What does a conservative case look like?

How to use these articles

Start with a calculator or practical guide when you are planning equipment. Use news and market explainers for context, then verify local rules, equipment documents, and professional requirements before acting.
