Solar Power & Battery Storage

How much can I save with solar panels in Victoria?

+

Most Victorian households save 60-90% on their electricity bills with a properly sized solar system. The exact savings depend on:

  • Your current electricity usage and bills
  • The size of your solar system
  • Your roof orientation and shading
  • Whether you add battery storage

A typical 6.6kW system can save $1,500-$2,500 annually. With current rebates, most systems pay for themselves within 3-5 years.

Do I need battery storage with my solar panels?

+

Battery storage is optional but highly recommended for maximum savings and energy independence. Benefits include:

  • Store excess solar energy for evening use
  • Backup power during outages
  • Reduce grid dependency to near zero
  • Protection against rising electricity prices

You can start with solar panels and add batteries later, but it's more cost-effective to install them together.

Will solar panels work on cloudy days?

+

Yes, solar panels still generate electricity on cloudy days, though at reduced capacity. Modern panels can produce:

  • 10-25% of normal output on heavily overcast days
  • 40-75% on partly cloudy days
  • Full output when sun breaks through clouds

Victoria receives excellent solar conditions year-round, with enough sunshine to make solar highly cost-effective even during winter months.

How long do solar panels last?

+

Quality solar panels typically last 25-30 years or more with minimal maintenance. Our systems include:

  • 25-year manufacturer warranties on panels
  • 10-year product warranties on inverters
  • Our 10-year workmanship warranty
  • Performance guarantees (usually 80% after 25 years)

Many panels from the 1980s are still producing electricity today, proving their long-term reliability.

Solar Pool Heating

How much warmer will solar heating make my pool?

+

Solar pool heating can increase your pool temperature by 8-15°C above the unheated temperature, depending on:

  • Size and orientation of solar collectors
  • Pool size and location
  • Weather conditions and season
  • Use of pool covers

Most customers achieve comfortable swimming temperatures of 26-28°C from April to October, extending their swimming season by 4-6 months.

What's the difference between solar pool heating and heat pumps?

+

Solar collectors use free solar energy with zero running costs, while heat pumps use electricity but work in all weather:

Solar Pool Heating:

  • No running costs
  • Environmentally friendly
  • Weather dependent
  • Lower upfront cost

Pool Heat Pumps:

  • Consistent heating regardless of weather
  • Faster heating
  • Higher running costs
  • Can be combined with solar for best results

Can I retrofit solar heating to my existing pool?

+

Yes, solar pool heating can be added to virtually any existing pool with a pump and filtration system. The installation involves:

  • Mounting collectors on your roof or ground
  • Connecting to your existing pool pump
  • Installing automatic temperature controls
  • Integrating with your current filtration system

Most installations take 1-2 days with minimal disruption to your pool use.

How much roof space do I need for pool heating?

+

Generally, you need collector area equal to 50-100% of your pool surface area for effective heating. For example:

  • 8m x 4m pool (32m²) needs 16-32m² of collectors
  • Larger pools or cooler climates need more collector area
  • North-facing roofs are ideal, but east/west work well too
  • Ground mounting is possible if roof space is limited

Our team will assess your roof and recommend the optimal collector size and placement during your free consultation.

Heat Pump & Solar Hot Water

What's the difference between heat pump and solar hot water?

+

Both systems use renewable energy but work differently:

Heat Pump Hot Water:

  • Extracts heat from ambient air (works like reverse air conditioning)
  • Works in all weather conditions, day and night
  • Uses some electricity but 3-4x more efficient than electric
  • Compact design, easier installation

Solar Hot Water:

  • Uses solar collectors to directly heat water
  • Minimal running costs on sunny days
  • Requires backup heating for cloudy periods
  • Larger roof space requirements

How much can I save on hot water bills?

+

Heat pump systems typically save 60-75% on hot water costs compared to electric hot water. For an average family:

  • Electric hot water: $800-1,200 annually
  • Heat pump hot water: $200-400 annually
  • Potential savings: $500-800 per year

With current Victorian rebates up to $1,000, most heat pump systems pay for themselves within 2-4 years.

Do heat pumps work in cold weather?

+

Yes, modern heat pumps work efficiently even in cold weather. Quality units operate effectively down to -10°C and include:

  • Frost protection systems
  • Cold weather optimization
  • Backup electric elements for extreme conditions
  • Consistent hot water year-round

Victoria's climate is ideal for heat pumps, with consistent performance throughout the year.

How long does a heat pump hot water system last?

+

Quality heat pump systems typically last 10-15 years with proper maintenance. Our systems include:

  • 5-8 year manufacturer warranties
  • Our workmanship warranty
  • Annual maintenance recommendations
  • Replacement parts availability

Regular maintenance every 2-3 years ensures optimal performance and extends system life.
