WASTING SOLAR POWER? PAYING TOO MUCH FOR EV CHARGING?

Without a smart system, your EV might be charging from expensive grid power even when your solar panels are producing excess energy.

💸

HIGH CHARGING COSTS

Charging an EV on standard grid electricity can add over $1,000/year to your bills – negating the savings of going electric.

☀️

SOLAR OVERFLOW

When you charge without a smart system, excess solar often goes to the grid for mere cents, while your EV might draw power from the grid.

MISSED OPPORTUNITIES

Time-of-use discounts, free solar hours, and your home battery's output – a regular charger can't take advantage of these, leaving savings on the table.

📱

JUGGLING APPS & TIMERS

Manually switching plugs or using multiple apps (solar app, EV app, etc.) is a hassle. It shouldn't require constant attention to charge efficiently.

MEET JOUSTO – YOUR HOME ENERGY BRAIN

Jousto brings together a smart EV charger and a powerful home energy hub. It's not just an EV charger – it's an energy automation system that knows when to draw from your solar, when to tap off-peak grid, and even how to share energy with your battery.

WHY CHOOSE JOUSTO?

Our smart EV charging solution offers benefits that standard chargers simply can't match.

💰

SLASH CHARGING COSTS

By prioritising free solar energy and cheap rates, you could charge at effective rates of just a few cents per kWh (some users pay $0 when solar covers it!).

FAST OR FLEXIBLE – YOU DECIDE

Need a quick charge? Override to boost at full power from grid + solar. Otherwise, let Jousto trickle-charge on sunshine. You get the best of both worlds.

☀️

MAXIMISE YOUR SOLAR INVESTMENT

Every kWh sent to the grid earns maybe 5-10c; using that in your EV saves you ~30c/kWh. Jousto ensures your solar goes into your battery or car first.

🔋

EXTEND BATTERY LIFESPAN

By managing the load, Jousto avoids overloading your home or grid connection. It can prevent your home battery from cycling unnecessarily.

EV CHARGING FAQs

Will this work with my car model?

Yes – Jousto works with all EVs and PHEVs. We either interface through the charger or directly with certain car APIs. From Teslas to Nissan Leafs, we've got you covered. Our system is compatible with all J1772 standard plugs, which is the Australian standard for EV charging.

Do I need a specific solar inverter or battery?

No specific brand needed. Jousto is compatible with most common solar inverters (Fronius, SolarEdge, GoodWe, Sungrow, etc.) and batteries. We'll check compatibility or use sensors to gather data if direct integration isn't available. Our system works with both new and existing solar setups.

What if I don't have a home battery?

No problem – Jousto will focus on your solar and grid. You can add a battery later and Jousto will integrate it then. Many of our customers start with solar + EV charging, then add battery storage as a future upgrade when they're ready.

Can I still charge my car quickly if needed?

Absolutely. You can always override to charge at full power (e.g., if you need to top-up in a hurry). Jousto's app allows you to switch to Fast Charge mode, after which it can revert to smart mode automatically. This gives you the flexibility to charge quickly when needed while still optimising for solar and off-peak rates most of the time.

Is the GoodWe charger any good?

Yes – GoodWe's 7kW (single-phase) and 22kW (3-phase) chargers are robust and affordable. They come with IP66 weatherproofing and a 2-year warranty (extendable). We pair it with Jousto to add smart features beyond its standard capabilities, giving you a great balance of cost and performance.

How much does this setup cost?

It depends on your configuration. Our GoodWe chargers start around $899, and the Jousto Energy Hub (with installation and setup) starts from $699. We'll provide a tailored quote – and remember, it's an investment that can pay itself off through energy savings in a few years. Also, financing options and any applicable rebates can make upfront costs easier.

How many solar panels do I need to charge my EV?

As a rule of thumb, we recommend about 1.5 kW of solar per 10-15 km of daily driving. For example, if you drive 50 km per day, an additional 5-6 kW of solar would cover your EV charging needs. However, this varies based on your driving habits, EV model, and local conditions. Our team can provide a personalised assessment based on your specific situation.

Save on Power: Energy Tips for Aussie Small Businesses

April 25, 20257 min read

Small businesses in Australia are grappling with rising electricity prices, and a surprising number are overpaying for power unnecessarily. Much of this stems from staying on default electricity contracts known as Standing Offers, misunderstanding complex tariff structures, and not utilising energy-saving strategies or technology. Fortunately, these challenges are solvable.

By taking charge—through regular comparison of energy plans, conducting energy audits, investing in energy-efficient upgrades, and exploring innovative tools like Jousto—businesses can reduce their electricity bills and boost their bottom line. This blog dives into the core reasons for overpayment and outlines practical, actionable solutions tailored to the unique needs of Australian small businesses.


The Challenge: Rising Energy Costs and Small Business Vulnerability

The rising cost of living in Australia isn’t just affecting households—small businesses are equally burdened. Electricity costs have become a critical operational expense, eating into profit margins and challenging long-term viability.

In many industries, electricity expenses now outweigh fuel and stock costs, making power prices a top priority. What’s more troubling is that many business owners are unaware they’re overpaying by hundreds or even thousands of dollars a year due to avoidable factors. This blog will uncover those causes and present a clear roadmap to reverse the trend.


Why Are Australian Small Businesses Overpaying for Power?

The Trap of Standing Offers

One of the biggest contributors to inflated energy bills is the Standing Offer—a default plan assigned when businesses fail to negotiate or renew their energy contracts. These rates are typically higher than Market Offers, yet over 147,000 small businesses remain on them.

Regulated prices such as the Default Market Offer (DMO) and Victorian Default Offer (VDO) serve as price ceilings but often don’t represent the best deal available. Many businesses get stuck on these plans after:

  • Moving premises

  • Letting an old contract expire

  • Never comparing options to begin with

This complacency leads to overspending, as retailers rarely offer their best deals to passive customers.

Tariff Complexity and Demand Charges

Electricity billing is notoriously confusing. Between flat rates, time-of-use tariffs, and demand charges, it’s difficult for business owners to know what they’re really paying for. Of particular concern are demand charges—fees based on your peak energy usage in a billing cycle, not your overall consumption.

This means a short period of high usage can trigger hefty fees, even if your overall energy use is modest. Many businesses don’t even realise they’re on a tariff with demand charges or how they can be avoided.

Market Volatility and Regulatory Changes

Australia’s energy market is subject to global fuel prices, domestic supply issues, and regulatory changes. The cost of updating poles, wires, and integrating renewables into the grid is frequently passed on to consumers, causing unpredictable bill increases.

Though regulators cap prices with the DMO and VDO, these are not guaranteed to be affordable—only a reference point, not a bargain.

The Loyalty Penalty

Another trap is the so-called "loyalty penalty", where customers who stay with the same provider often pay more than new customers. Discounts and incentives are routinely reserved for new sign-ups, leaving long-term clients with outdated and expensive plans.

Factors Like Size, Location, and Operating Hours

Other contributing variables include:

  • Business size – larger operations naturally consume more

  • Location – different regions have different network tariffs

  • Hours of operation – businesses that run during peak times face higher charges

Understanding these unique conditions is essential for tailoring the right cost-saving strategy.


How to Reduce Electricity Costs: A Guide for Small Businesses

Compare and Switch Energy Plans Regularly

The most straightforward cost-saving step? Stop accepting the default. Use government comparison websites like:

These platforms allow you to compare plans based on your actual usage. The average small business can save up to $1,160 per year by switching to a better Market Offer.

Tip: Set a calendar reminder to compare plans once a year.

Conduct an Energy Audit

An energy audit helps identify inefficiencies in your business. Auditors will:

  • Analyse past bills

  • Examine lighting, HVAC systems, and appliances

  • Recommend changes based on your operations

Government grants and rebates are often available to subsidise audit costs. The long-term savings can be substantial, especially when inefficiencies go unnoticed for years.

Invest in Energy-Efficient Equipment and Infrastructure

Some of the highest ROI upgrades include:

  • LED lighting (up to 75% more efficient)

  • High-efficiency HVAC systems

  • Energy-rated refrigerators and appliances

  • Smart thermostats and timers

  • Insulation and draught sealing

Many of these qualify for tax deductions under the Small Business Energy Incentive, making the upfront investment more affordable.

Install Solar Power and Battery Storage

Australia’s solar conditions are ideal, and the cost of solar panels has dropped significantly. For small businesses:

  • Rooftop solar can slash daytime electricity usage

  • Battery storage allows usage of solar energy at night or during peak times

  • Feed-in tariffs may provide additional income

Federal and state governments regularly offer solar rebates and incentives, making this option increasingly attractive.

Optimise Tariffs and Manage Demand

Understand your usage patterns. If your peak usage is predictable, consider:

  • Time-of-use tariffs if you can shift work to off-peak hours

  • Load shifting to reduce demand charges (e.g., staggering equipment start times)

  • Staff education to reduce energy waste

Even small behaviour changes can reduce demand charges, often the most punishing part of your bill.

Utilise Government Incentives and Grants

Stay informed about:

  • The Small Business Energy Incentive (bonus tax deductions)

  • State-based rebate schemes

  • Energy audit subsidies

These schemes can cover a significant portion of your upgrade or audit costs. Check your local government’s website or contact an energy broker for up-to-date information.

Engage an Energy Broker

Energy brokers can:

  • Compare dozens of retailers on your behalf

  • Negotiate custom pricing

  • Help switch providers with minimal hassle

They understand tariff structures and market trends, saving you time and ensuring you’re not missing better deals.

Implement Low-Cost or No-Cost Changes

Small changes can add up:

  • Turn off appliances when not in use

  • Use energy-saving modes on electronics

  • Adjust thermostats by 1–2 degrees

  • Maintain equipment to ensure efficiency

  • Maximise use of natural light

These practices require no capital investment but can cut electricity usage by 5–15%.

Consider GreenPower for Sustainability

If your business is committed to sustainability, GreenPower allows you to:

  • Purchase energy from 100% renewable sources

  • Reduce carbon footprint

  • Appeal to environmentally conscious customers

Though slightly more expensive, the brand credibility and customer trust it builds can be worth the investment.
