Solar power basics

Solar power basics

This guide explains what solar power is, how it works, and when it makes sense for different use cases.

Key takeaways

  • Solar panels convert sunlight into usable electricity.
  • Systems can be grid-tied, hybrid, or off-grid.
  • Costs depend on size, components, and installation.

What solar power is

Solar power uses photovoltaic (PV) panels to turn sunlight into direct current (DC) electricity. An inverter converts that DC into alternating current (AC) for typical appliances.

How solar systems work

A complete system includes panels, an inverter, wiring, and often a battery. The flow is: sunlight → panel output → charge controller (optional) → inverter → appliances.

Pros and cons

Pros Cons
Lower long-term energy cost Upfront equipment cost
Quiet, low maintenance Output depends on sunlight
Scales for many use cases Requires correct sizing
