The lesson
Estimate energy: each device's watts × hours used per day, added up in watt-hours.
A solar system needs panels sized for the daily energy and local sunlight, batteries for night and cloudy days, and an inverter.
Use reputable equipment and qualified installers; poor installations are a fire risk.
Step by step
- List devices and daily hours.
- Calculate watt-hours per day.
- Outline panel and battery needs.
- Note installation requirements.
Practice activity
Outline a solar backup plan for the case site.
Expected result: An energy estimate and system outline.
