the business case for
Be it residential or business, at the centre of a well-designed smart energy solution is an expandable value chain that is capable of on-demand energy delivery; and is future proof.
The solution must be robust, agile, and be a self-managing ecosystem that will deliver sustainable energy security at the least cost to business.
Government Rebate & ROI/Payback: With government rebates up to 50% towards a solar installation, together with feed-in tariffs (FIT’s) and renewable energy certificates (REC’s), you can own your smart energy system within 2.5 years and 5.0 years (subject to scope of work)
Least Cost (LC)
By considering your –

Types of Solar Technology
There are two main types of solar energy technology:  Solar Photovoltaics (PV) and  Solar Thermal Energy (STE).
Solar PV is the rooftop solar you see on homes, businesses, industrial and at agricultural sites.
Solar Thermal (STE) is a form of energy technologies that involve harnessing solar energy for thermal energy (heat). The technologies comprise flat or parabolic collectors (low, medium and high temperature collectors) concentrating sunlight mainly using mirrors and lenses.
Australia receives thousands of times more solar energy from the sun each year than all fossil fuel use combined. We directly use only about one millionth of this at the moment as commercial energy.
Commercial: In many circumstances, a HTL SmartEnergy micro solar PV solution mounted on building roofs can produce as much electricity as the building consumes. A typical module will generate about 200 kilowatt hours (AC) per square meter per year. A macro solar PV solution will produce as much energy an industrial estate would need.
Residential: A collector area of 25-50m2 is needed to power a reasonably energy-efficient Australian house. Such a house will export more electricity to the grid during the day than it imports at night. A HTL SmartEnergy macro solar PV solutions is ideal for residential building/complex.
How it works
Solar photovoltaic (PV) is an elegant technology which produces electricity from sunlight without moving parts.
In a photovoltaic cell, sunlight detaches electrons from their host silicon atoms. Tiny packets of light energy called photons are captured by electrons, and impart enough energy to kick the electron free of its host atom. Near the upper surface of the cell is a “one way membrane” called a pn-junction. The pn-junction is formed by diffusing tiny quantities of phosphorus to a depth of about one micrometre into a thin wafer of silicon.
When a free electron crosses the pn-junction it cannot easily return, causing a negative voltage to appear on the surface facing the sun (and a positive voltage on the rear surface). The front and rear surfaces can be connected together via an external circuit in order to extract current, voltage and power from the solar cell.
Solar cells are packaged behind glass to form photovoltaic modules, which have typical service lives of 20 to 40 years.
Both, Sola PV and STE produce direct current (“DC”).
Through Power Inverters, or Inverters, the DC is converted into alternating current (“AC”) 240v for use in residential, commercial, industrial and agricultural environments.
Value for Money
The costs and benefits of solar batteries will determine whether or not you should install a solar panel system that includes energy storage. With a standard solar energy system, the economics are fairly easy to understand: if you have high electricity bills, installing solar panels to produce your own power is an investment that will pay off in just a few years.
The Case for Batter Storage
Once you add a solar battery to the mix, the economics become more multi-layered.
How much do solar batteries cost?
Before you can determine if installing a solar battery makes sense, you’ll need to know the price. Like solar, you can think of the costs as both a gross price and a price per relative capacity. Solar batteries range from $5,000 to $20,000+ and from $400 dollars per kilowatt hour (kWh) to $750/kWh. Note that these prices are only for the battery itself, not for the cost of installation or additional supporting equipment as may be required.
Similar to advancements made in solar panels, renewable batteries are also seen technology advancements. These include the replacement of lithium in lithium-ion with a cheaper sodium option to produce sodium-ion batteries. Others include ryden dual carbon, lithium-sulfur, solid-state. As such, the list price of solar batteries is largely driven by  technology advancement;  materials used in manufacture; and  how much power they can give you (hold).
Installing a battery that can operate off-grid typically also costs more than installing a battery designed to operate while connected to the grid.
Similar to how solar panel prices have fallen dramatically in the past few years, experts predict that solar batteries will become less expensive in the years to come as well.
What is Net Metering?
Net meters work by continuously sampling how much electricity is being generated and how much electricity is consumed at your home or business. At each point in time the meter instantaneously reads the generation and consumption of the premises and the meter records both these amounts. The data is then accumulated in the appropriate register over the billing cycle.
The meter is read and the bill is calculated.
Now that high government sponsored feed-in tariff (FIT’s)* have stopped to be available for new customers, it is very likely that a net meter is the best way to meter your electricity after you solar power system has been installed.
Creating a Revenue Stream: Under net metering, the electricity generated by your system and consumed in your home or business, you pay nothing for this electricity. The excess electricity produced is exported to the grid – and you can earn from the FIT’s exported.
Feed-in Tariff (FIT) Rates
A feed-in tariff is a credit customers are paid for any unused electricity that their solar power system sends back to the power grid. It is usually a set rate per kilowatt hour and paid as a credit on electricity bills.
As the FIT rate varies from one energy retailer to the next… HERM Tech Logic will go-to-market, negotiate and secure the best FIT’s for you.
Renewable Energy Certificates (REC)
A Renewable Energy Certificate (REC) is a measurement of renewable energy that can be traded or sold.
HERM Tech Logic, where permissible under the scheme, will create and manage eligible REC’s type for you:
- Small-scale Renewable Energy Scheme (SRES), for systems under 100 kW. This is the scheme that applies to residential Solar PV systems.
- Large-scale Renewable Energy Target (LRES), for systems above 100 kW.
Smart home and smart office, including smart warehouse, store, farm, has completely change the way we live and work.
With the explosion of technology protocols, product interoperability is ‘the most critical consideration’ when selecting features, functions and affordability of a smart home/office solution.
Through the right technology ecosystem, owners of smart automation can remotely operate their security system, see and communicate with who is at the front door or gate and provide access, control HVAC (heat, ventilation, air conditioning), control lighting, control blinds and shutters, and programme an entertainment system that reflects your work place and lifestyle within designated areas.
These features and functions can all be monitored, controlled and accessed via a smartphone, tablet or laptop … from anywhere at anytime.
