Interest in solar power is growing rapidly in the US, driven by a desire for clean energy, potential cost savings, and government incentives. A Complete Guide to Solar Home Systems in the US

This article explores everything you need to know about installing a solar home system in the US, from how it works to the financial considerations and the steps involved in getting started.

How Does a Solar Home System Work?

A typical solar home system consists of several key components:

Solar panels: These panels, made from photovoltaic (PV) cells, are the workhorses of the system. When sunlight hits the PV cells, they generate electricity through a process called the photovoltaic effect.

Inverter: The inverter takes the direct current (DC) electricity produced by the solar panels and converts it into alternating current (AC) electricity, which is the type of electricity used in your home.

Mounting system: This framework securely holds the solar panels on your roof, ensuring they are angled towards the sun for optimal energy production.

Monitoring system (optional): This allows you to track your system’s performance and monitor your energy production in real-time.

Here’s a simplified explanation of the process:

1. Sunlight strikes the solar panels.
2. The PV cells in the panels convert sunlight into DC electricity.
3. The DC electricity flows to the inverter.
4. The inverter converts the DC electricity into AC electricity.
5. The AC electricity is then used to power your home appliances and lights.
6. Any excess electricity produced can be sent back to the utility grid in a system called net metering (explained later).
