Question 3

How does a solar photovoltaic (PV) system function?

Accepted Answer

A solar photovoltaic (PV) system generates electricity using silicon-based solar panels installed on the roof of a home or commercial building. These panels absorb sunlight and convert it into direct current (DC) electricity. One or more inverters then transform this DC power into alternating current (AC), which is the same type of electricity supplied by the grid. Once converted, the solar energy can be used immediately to power household appliances or stored in a battery for later use, depending on your energy consumption needs.

Australian consumers have access to a wide range of solar packages from various manufacturers, suppliers, and installers. Some common types include:

String Inverter Systems – These systems connect one inverter to one or two arrays (or ‘strings’) of solar panels on the roof. They are generally more affordable and easier to install but may experience efficiency losses due to shading or excessive heat. Modern string inverters come with Hybrid and Grid-Tied options, featuring Wi-Fi connectivity and a range of functions to enhance performance.

Micro Inverter Systems – These systems use smaller inverters attached individually to each solar panel, optimizing energy output and overall system efficiency. Unlike string inverters, micro inverters ensure that if one panel is shaded, the rest continue to operate at peak efficiency. While they offer better energy performance, micro inverter systems are typically more expensive than other options.

To maximize solar output, it’s essential to install panels in a location with minimal shading and an optimal tilt angle for your region.

Question 17

Will solar panels work during a power outage?

Accepted Answer

Standard grid-connected solar systems do not function during a blackout unless they are paired with a battery backup system. This is because most solar inverters are designed to shut down when they detect a grid failure, ensuring that no electricity is sent back to the grid, which could pose a safety hazard to repair crews.

However, if you have a solar battery system with blackout protection, your stored solar energy can be used to power essential appliances during an outage.

Battery Backup Systems: A battery, such as a Tesla Powerwall or LG Chem, can store excess solar energy for use at night or during power outages. However, not all batteries provide full home backup; many systems only support essential circuits.
Prioritizing Essential Appliances: If using a battery during a blackout, you should prioritize running critical appliances like refrigerators, lighting, and basic power points. High-energy devices such as air conditioners and pool pumps can drain the battery quickly.

If blackout protection is important for you, make sure to discuss battery storage options with your solar provider before installation.
