Electricity Basics: Rates & Quantities of Electrical Energy

Learn the fundamentals of measuring rates and quantities of electrical energy, tailored for DIY solar enthusiasts.

This short, two-part video series is the best place to start if you’re new to DIY solar or just need a refresher on the fundamentals of electrical energy. We also have an article on the basics of electricity if you prefer reading an article to watching videos.

Rates of Electrical Energy

It all starts with understanding electrical potential (voltage), rate of electrical current (amperage), how these two combine to produce power (Watts), and opposition or resistance to flow (ohms).

Quantities of Electrical Energy

With an understanding of energy rates, we can now work with measurements that are more meaningful to us as electricity users: quantities of electrical energy over time.
