Expert warns: Kidults sending parents broke on power and other costs

Australians are being urged to review their solar battery systems as changing household circumstances quietly drive electricity consumption far beyond what many systems were originally designed to handle.
 

According to solar energy expert Steven Yu, founder and CEO of Aussie Solar Batteries, one of the most common conversations his team is now having with homeowners starts with a simple complaint.
 

"My power bills are creeping up again and I don't know why."
 

More often than not, the answer has nothing to do with the solar system itself.
 

"Life changes. When people install solar and batteries, they size the system based on the household they have at that moment. Five years later, the household often looks completely different," Yu said.
 

The return of the adult children
 

Yu said one of the biggest trends impacting household energy use is the growing number of adult children moving back home.
 

"We are seeing children return home while they save for a deposit, build a house, recover from a relationship breakdown or simply try to manage rising living costs," Yu said.
 

"In many cases, they don't come alone. They bring partners, children, computers, televisions, gaming systems, extra washing, extra showers and extra air conditioning."
 

He said what was once a household of two can quickly become a household of five or six.
 

"Suddenly your battery that comfortably lasted all evening is empty by 8pm."
 

The hidden energy explosion
 

Yu said many households fail to appreciate how quickly electricity demand can increase.
 

"One additional person can have a surprisingly large impact on power consumption. Add multiple people and the change can be dramatic," he said.
 

"It is not just lights and televisions. It is hot water, cooking, laundry, charging devices, heating, cooling and working from home."

He said visitors staying longer, elderly parents moving in or grandchildren spending more time at the property can all contribute.
 

"We often find people blame the battery when the real issue is that their household is consuming significantly more energy than when the system was installed."
 

Building bigger homes requires bigger batteries
 

Yu said renovations and home extensions are another growing factor.
 

"When people add bedrooms, granny flats, home offices, pools or entertainment areas, they are also adding energy demand," he said.
 

"Unfortunately many homeowners forget to review whether their solar and battery system is still suitable."
 

He said this can result in households purchasing more electricity from the grid despite having a substantial solar investment.
 

"The battery may be performing exactly as designed. The problem is that your energy needs have changed."
 

Can you add more battery storage?
 

The good news, according to Yu, is that many battery systems can be expanded.
 

"Depending on the brand and model, additional battery modules can often be added to increase storage capacity," he said.
 

"This can be one of the most cost-effective ways to improve performance if your household demand has grown."
 

However, he said not every battery can be upgraded indefinitely.
 

"Some older systems have limitations and some manufacturers only allow expansion within certain timeframes."
 

In those situations, replacing the battery system may be the better long-term option.
 

Should you add more solar panels?
 

Yu said battery capacity is only part of the equation.
 

"If your battery is empty every night, the first question is whether it is being fully charged during the day," he said.
 

"If you have significantly increased your electricity consumption, you may need additional solar panels as well as additional storage."
 

He said many homeowners assume the battery is the issue when the real problem is insufficient solar generation.
 

"You cannot store energy that you never generated in the first place."

The first thing homeowners should do
 

Before spending money, Yu recommends undertaking a professional energy review.
 

"We look at historical consumption, current usage patterns, battery performance and solar generation to identify exactly what is happening," he said.
 

"Every household is different and there is no one-size-fits-all solution."
 

He said some homes only require additional storage, others need more panels and some simply need changes to how electricity is used throughout the day.
 

The cost of doing nothing
 

Yu warned that ignoring the issue can become expensive.
 

"Many households install solar and batteries specifically to reduce reliance on the grid," he said.
 

"If your household doubles in size and your energy infrastructure stays the same, those savings can start disappearing."
 

He said reviewing a system every few years should become standard practice.
 

"People review their insurance, their mortgage and their superannuation regularly. Your solar system should be no different."
 

Solar systems need to evolve with life
 

Ultimately, Yu said the biggest mistake homeowners make is assuming the system they installed years ago will always meet their needs.
 

"Families grow, children move back home, renovations happen and lifestyles change," he said.
 

"Your solar system should evolve with your life. The good news is that in many cases there are simple solutions. The key is identifying the problem before those electricity bills start climbing again."
