Let\u2019s break it all down.<\/p>\n\n\n\n
Q: How many kW does my home actually need?<\/strong><\/h3>\n\n\n\nDon\u2019t totally depend on what a salesperson suggests \u2014 your actual energy usage matters.
Someone who works from home needs a different system than someone who\u2019s out all day.<\/p>\n\n\n\n
Example:<\/strong><\/p>\n\n\n\nSarah from Craigieburn was offered a 6.6 kW system because \u201cit\u2019s the standard.\u201d
But when she came to us and we checked her bills, we realised her home used more power at night.
An 11 kW system with a battery<\/a> made far more sense \u2014 and now she barely pays a bill.<\/p>\n\n\n\nQ. Is solar in Victoria worth it?<\/strong><\/h3>\n\n\n\nYes \u2014 Victoria is still one of the best places in Australia to go solar.
STC rebates alone cut costs by around $2,800\u2013$4,000, and eligible homeowners can get an extra $1,400 off through Solar Victoria. Electricity rates are high in VIC, so most families see a payback in just 3\u20135 years. Modern panels also perform well even in winter.<\/p>\n\n\n\n
Example:
<\/strong>A typical family in Melbourne installing a 6.6 kW system often slashes their bill by 60\u201380%. If they add a battery, it usually jumps to 80\u201390%, especially during evening peak times.<\/p>\n\n\n\nQ<\/strong>. What is the 20% rule for solar panels?<\/strong><\/h3>\n\n\n\nThe \u201c20% oversizing rule\u201d simply means your solar panels can be a bit bigger than your inverter \u2014 up to 20% more. This is actually a good thing for most homes.<\/p>\n\n\n\n
Example:
<\/strong>If you install a 5 kW inverter<\/strong>, you can safely add up to 6 kW of solar panels<\/strong>. So even on cloudy winter mornings in Victoria, your system can still produce strong output because the panels are working harder to feed the inverter.
<\/p>\n\n\n\nIn short, a slightly oversized panel setup gives you more energy and better savings without extra complication.<\/p>\n\n\n\n
Q. What is the biggest downside to solar electricity?<\/strong><\/h3>\n\n\n\nThe biggest downside of solar is that it only works when the sun is out. Cloudy days reduce output, and at night you still rely on the grid unless you have a battery.<\/p>\n\n\n\n
Example:
<\/strong>If most of your energy use happens in the evening, solar alone won\u2019t cover it \u2014 a battery setup<\/a> helps store daytime energy for later.<\/p>\n\n\n\nOther downsides include upfront costs, lower feed-in tariffs, and cheap systems wearing out early.
Still, most Victorian homes save more than they spend, so the benefits usually outweigh the drawbacks.<\/p>\n\n\n\n
Q<\/strong>. Why are people getting rid of their solar panels?<\/strong><\/h3>\n\n\n\nFA small number of homeowners end up removing their solar panels, and it\u2019s usually for practical reasons \u2014 not because solar stopped working. Older systems (10\u201315 years) often produce far less than today\u2019s modern panels, and with current rebates, upgrading can be cheaper than repairing. Some people also remove panels due to poor-quality installations from the early solar boom, or because they\u2019re renovating, extending, or re-roofing their home. Others upgrade to a bigger system or add a battery, which sometimes requires a full reconfiguration.<\/p>\n\n\n\n
In most cases, panels are removed because people are upgrading \u2014 not because solar failed.<\/p>\n\n\n\n
