Commercial Solar Farms & Large Arrays

As Australia is in one of the world’s solar “hot zones” this provides maximum exposure to the sun’s rays throughout the year.  This abundant energy source is FREE to capture and convert it to usable power for business or factory's and whole towns.

Investing in a large capacity Solar Farm is a huge investment – But can pay for itself in a few short years, and thereafter return an ongoing income stream for decades!  Private or community owned solar farms would be smarter and better off becoming a proper Electricity Retailer, and sell there power to the local community, thereby supporting the local homes & businesses, making this type of solar farm a proper Electrical Retailer, unlike the current deceptive Retainers that don't actually supply or pay for the power you consume!

How much does a Commercial Solar Array or Solar Farm cost ?

This can become a very complicated subject - we consider a small commercial solar array to harvest upwards of 100kW (power) day to be a good starting point, usually solar farms are measures in MWh (1MW=1'000kW).

Because of the cheaper wholesale cost, there are many businesses selling older 250W solar panels, be aware there is a huge harvesting difference between 250W and newer 500W panels that harvest 50% more power, the below figures show the substantial difference.

50x 250W panels =12.5kWh Array;

50x 270W panels =13.5kWh Array;

  • Fixed Flat-panes =63kWh, 6hr day peak.
  • Single-axis Tracking =100kWh, 8hr day peak.
  • Duel-axis Tracking =137kWh, 10hr day peak.
  • Fixed Flat-panes =68kWh, 6hr day peak.
  • Single-axis Tracking =110kWh, 8hr day peak.
  • Duel-axis Tracking =150kWh, 10hr day peak.
   

50x 350W panels =17.5kWh Array;

50x 500W panels =17.5kWh Array;

  • Fixed Flat-panes installed =88kWh, 6hr day peak.
  • Single-axis Tracking installed=140kWh, 8hr day peak.
  • Duel-axis Tracking installed=190kWh, 10hr day peak.
  • Fixed Flat-panes installed =88kWh, 6hr day peak.
  • Single-axis Tracking installed=140kWh, 8hr day peak.
  • Duel-axis Tracking installed=190kWh, 10hr day peak.

Note that Fixed Flat-panel installations only harvest Peak power efficiently for 4~6 hours per day, where Single-axis solar tracking can harvest Peak power for 7~8+hr per day, where Duel-axis tracking rains supreme, can harvest Peak power for 10~14hr per day in locations with clear Easterly, Northern & Westerly horizons, and where the sun is not impeded by buildings or terrain, the further South the better!

Final system cost can vary greatly depending on whether single phase (240v) or 3 phase (480v) power is required, 3 phase power can be produced using one or three or more separate inverters, on large solar farms, sub-station may be required.

We only recommend Hybrid Inverters for small solar-farms using battery storage, as they allows you to import other forms of power into your system.

If your are a small/medium business using less power than you produce per day and your want to get your system paid off by your electricity savings, then we strongly advise you invest in a battery bank of no less than 20% of your highest daily kWh usage - then you will be able to store the lion share of power production into your battery bank, once the batteries are full, you then have the choice to export any excess power into the state grid, and gain a 6c to 11c/kwh feed-in Tariff, that may cover the State Grid "Supply Charge".

With a stand-alone Solar Farm the return on savings will start relatively quick, however, incorporating energy storage system to import excess power into, will do two things, firstly allow the owner to black-out proof there business and secondly reduce the reliance of importing power from the state grid, usually after sunset and at a far more expensive rate!

Electricity prices should benefit from increased renewable supply because the need for high cost, long distance transmission will be reduce as generation is distributed through private grid feeds. Introducing increased transmission storage to be later exported for peak power feed-in Tariff (Rebate) will further reduce network infrastructure needs by the deceptive self regulating State Grid justifications, and upgrades fall. The regulators need to push providers as they have a disincentive under the current arrangements.

Excess power produced that is Not sent to short term storage systems, in many cases will produce a feed-in Tariff for many years to come.  Using Solar and any alternative energy source, the best being Aqua generation closely followed by Wind generation will contribute to reducing reliance on fossil fuels and ensure a brighter future for our planet.

It is said that Solar power has the potential to provide over 1,000 times the total world energy consumption, though in 2016 it is reported that solar provided less than 1% of the total used.  Installing a solar farm will greatly contribute to increasing that figure.

What is a Solar Farm pay-back time?

This largely depends on calculating the size of the solar farm energy production and consumption, and whether using Single-Axis or Duel-Axis Tracking, as either of these will harvest substantially more energy than fixed panel arrays!

The other substantial expense is Labour for Installation & Wiring of the field Racking.  Energy storage is as equally important for energy security, as it allows for usage of stored power when in high demand!

We can provide you with a FREE feasibility estimation by supply the following information;

  1. Do you own or lease the land you intend to use for a solar form, if so what are the Costs ?
  2. Are you intending to build a solar farm that can/will be independent of the State Grid ?
  3. Do you intend to self consume &/or on-sell any excess power not self consumed ?
  4. The/Your intended Daily kW/MW of Energy Harvested &/or the Daily kWh/MWh Energy Consumed ?
  5. How far from the solar Arrays will the main Inverters or Consumption of power be located ?
  6. Are you considering a power storage system to blackout proof your premises ?
  7. What amount have you budget for ?

By providing those answers, it will enable us to assist you further!

Consider purchasing Battery storage, and backup Generator as part of your power system, it's worth calculating how the cost of the system compares with the saving you will make on your electricity bills, by using this Solar Farm break-even time & rate calculator, it provides a good estimation of future income/savings.  There are a range of factors that influence the payback period, including increases in electricity prices, ongoing maintenance and power storage equipment costs, which you should factor into the outlay costs.

It may be worthwhile checking if there are any state or even local government Rebates available for purchasing solar panels or a battery storage system. For example, Adelaide City Councildid/may still provide Rebates of up to $5,000 for installing a battery storage system or solar panels.

Levelised Cost Of Energy: The calculations of Levelised Cost Of Energy (LOCE) of these three Solar PV Technologies depend crucially on assumptions made about ($/kW) construction costs and annual capacity factors of the three solar technologies being considered.

Contracts for Difference: The purpose of CFD is to incentive investments in new low-carbon electricity generation by providing stability and predictability to future revenue streams. Governments state that; "we must de-carbonise electricity generation and it is vital that we take action now to transform permanently into a low-carbon economy and meet our renewable energy target by 2020 and our 80 per cent carbon reduction target by 2050. To put us on this latter trajectory, power sector emissions need to be largely de-carbonised by the 2030s. At the heart of this strategy to deliver this transition is a new system of long-term contracts in the form of CFD, providing clear, stable and predictable revenue streams for investors in low-carbon electricity generation".

CFD's explained: Is a financial hedging arrangement, where two parties agree to trade a certain volume of a product for a set price. These parties do not physically exchange this product in the ‘hedge market’. The product is purchased in a separate ‘physical market’ (e.g. a wholesale electricity ‘spot market’). If the price is higher or lower than the agreed price, then the parties settle the difference between the ‘hedge contract’ and ‘physical market’ prices. (Search, Electricity Futures Contract and Spot Market.)

CFD is usually a long-term contract between an electricity generator and Low Carbon Contracts Company (LCCC). The contract enables the generator to stabilise its revenues at a pre-agreed level (the Strike Price) for the duration of the contract. Under the CFD, payments can flow from LCCC to the generator, and vice versa. So, again, under the CFD's, when the market price for electricity generated by a CFD Generator (the spot market price) is below the Strike Price set out in the contract, payments are usually made by LCCC to the CFD Generator to make up the difference. However, when the reference price is above the Strike Price, the CFD Generator pays LCCC the difference.
