Generation, storage and demand
Understand an energy system through the different roles of its parts.
Start with useful demand
Consider what equipment needs to operate and for how long. Power describes a rate of energy use; energy describes the amount used over a period. These answer different questions.
Generation follows conditions
Energy sources have different characteristics. Solar generation changes with sunlight and other conditions, so design considers variation alongside equipment ratings.
Storage has several dimensions
Stored energy and available output power answer different questions. Efficiency, expected life, operating conditions and maintenance also affect storage choices.
Consider the whole life cycle
A system’s value includes upkeep and replacement as well as purchase. Efficiency and durability influence resource use and long-term practicality.
