When looking for an environmentally friendly and cost effective option for energy, it is no secret that solar panels are the way to go. Thousands of homeowners across Australia have decided to make the switch, powering their properties with clean and reliable electricity.
If you’re considering installing a solar photovoltaic (PV) system, it’s important to do the research, know what systems are on the market and what to ask your solar retailer for. To make your research as easy as possible, we’ve put together a quick list to help you understand the different systems available and what costs to expect:
Types of Solar PV Systems
There are three major types of solar PV systems, each with its own benefits:
1. Grid Connected Solar:
These systems convert electricity created by solar panels into AC electricity that is compatible with the electricity grid. Most homes with Grid Connected Solar will use solar power first, then when there is no solar power being generated at night they use electricity sourced from the grid.
2. Grid Connected with Battery Backup:
These are also known as uninterrupted power supplies due to the system’s ability to store energy created during the day in the battery, then use the battery stored solar power at night. These systems are still connected to the electricity grid and are growing in popularity for those who can take advantage of selling solar power back to the grid.
3. Stand Alone:
Standalone systems are not connected to the grid and are usually used in remote areas that typically have limited connection and/or low electricity demand. These systems must have batteries or a backup diesel or petrol generator to provide power at night.
While solar panels undoubtedly save you money long term, there are some initial upfront costs that you need to take into consideration. Renew Energy will guide you in choosing the right system for your budget, and walk you through some of the costs/incentives that may apply including:
- Government incentives and support schemes
- Type and number of needed panels
- Installation costs
- Framing equipment type and system components
- Number and type of panels
- Inverter type and size
- The height and accessibility of your roof
- After sale service agreements
There may also be some unlisted costs that could be included with the installation, such as:
- Meter changes or reconfiguration
- Applications to connect to grid
- Switchboard or cabling upgrades
- Removal of trees that block or shade panels
- Site preparations
While it’s essential you do some basic research, a good CEC approved retailer like Renew Energy will work with you throughout the process to make sure you get the right system for you, your energy needs and your budget.
