Battery Storage

2016 sees the introduction of Battery Storage options for businesses.

The main benefit of battery storage is to provide your own electricity in the peak consumption time of afternoons after 2pm when peak demand charges are prevalent and very expensive.

The main reliable and trusted brands available in Australia will be LG and Tesla.  They work with most panels, however, it is the inverter that they need to be connected to and thus compatible with that is important.  HCB Solar can advise you on this.

SMA and Fronius Inverters are battery ready with different components required to make them work with batteries.  HCB Solar can provide you with full costings.

The RRP cost is still to be clarified but a 70 kw system with batteries will cost $180,000 – $240,000.  So, using a cost of $210,000 after STC rebates already deducted.

70 kW Battery Solar System Cost / Benefit Analysis

  1. You decide on a 70.2 kW system (270 x Trina solar panels) and it costs you $210,000 out of pocket fully installed (after STC & excluding GST).
  2. You business is in Newcastle where a 70.2 kW system produces on average 265 kWh per day. This assumes a north facing roof with no shade issues and some normal efficiency losses.
  3. The price you currently pay for daytime electricity is approx $0.21/kWh.
  4. You use 70% of the energy your system generates and export 30% to the grid at $0.06 per kwh.
  5. Yearly System production = 265 units (kWh) x 365 days = 96,854 kWh per year
  6. Yearly Solar consumption  = 96,854 units (kWh) x 0.7 = 67,798 kWh (70% Consumed) = 29,056 kWh (30% Exported)
  7. Yearly Benefit = (67,798 x $0.21) + (29,056 x $0.06) = $15,981.
  • Cost $/kwh of solar over 25 year life of system = $0.09 /kwh
  • Return on Investment = $15,981/210,000 x 100 = 7.6% per annum
  • Payback period = $210,000/15,981 = 13.1 years
  • And the price of this electricity never goes up.

The new LG NeON® R at a similar physical size reached an incredible 360W (20.8% efficiency)!

This makes it ideal for solar systems seeking visually pleasing panels and for roofs where space is tight.

The NeON® R is also the right panel when future solar system expansion is considered. Or as a combo install of panels and solar energy storage via batteries as well as electric vehicle charging. The LG NeON® R is a very powerful module. The 30 multi-ribbon busbars at the rear of the module sets a new standard of innovation. It is the result of LG’s extensive solar R&D investment.

The LG NeON® 2 has seen many improvements, from

  • longer warranties,
  • higher efficiency,
  • stronger frames,
  • better wind loading.

is ideal for homes seeking a visually pleasing solar panel. And for roofs where space is tight or where you are considering future system expansions (e.g. to incorporate battery storage or electric car charging). The LG NeON® modules have double sided cells and CELLO technology absorb light from the front and the back of the cell. This technology sets a new standard for innovation and is internationally awarded.

The latest Mono X® Plus benefits from years of LG research. The fifth generation LG Mono X® Plus offers:

  • long warranties,
  • high efficiency,
  • strong frames,
  • Australia’s highest wind loading panel.

The LG Mono X® Plus will provide many years of clean, reliable energy. Choosing the high quality Mono X® Plus is an investment in superior standards of design, manufacture, back up support and warranties.
