Australia has a wealth of coal, coal and lignite for more than 100 years, and the current electricity generation in Australia is dominated by coal. Because of its reliance on coal, Australia's per capita carbon emissions are the highest. In 2010, Australia emitted almost 25 tons of carbon dioxide per person. Compared with China's emissions per capita of around 7 tons in 2015, Australia is 250% higher. Australia's carbon emissions per unit of GDP are second in 34 iced countries, behind Estonia. Now Australia has set a target of cutting its greenhouse gas emissions by at least 26 per cent by 2030.The weakest cuts in iced countries are almost certainly the weakest.
 

Normally, warehouse management system (WMS) was widely adopted for collecting data of warehouse in order to optimize the operation and management. However, the current WMSs have an obvious weakness in the terminal data gathering because they contain no feature of real-time and automatic data retrieval..
Among all the technologies, Radio Frequency Identification(RFID) is thought to be the most promising one. Because RFID technology meets the two main demands (efficiency and cost-effective) with the advantage of mini-size, strong penetrability, wireless readability, shape diversity, reusability and comparatively low-cost.
 

The off-grid generation system consists of solar panels, batteries and charging and discharge controllers and off-grid inverters. The solar energy controller (PV controller and the landscape complementary controller) regulates and controls the energy generated. One party, the adjusted energy is sent to the dc load or ac load, and the excess energy is transferred to the storage battery.

The RFID technology can be of most useful help in short range surveillance and monitoring as it is both efficient and cost effective. Using RFID tags to uniquely identify a person or an object is achieved easily. The whole apparatus is easily scalable to achieve higher distance ranges by using higher grade tags or by using battery powered active tags.
A key challenge in Radio Frequency Identification is to provide complete coverage using minimum number of readers. RFID technology is a rapidly developing means to track physical objects in real-time. As RFID technology requires no line of sight, multiple items (tags) can be read at the same time. Different types of RFID readers and tags (to store information) are available now.
 

A wide range of solar controllers, different applications on the controller requirements are not the same. Common types of solar controllers are divided into the following categories
 

There are two kinds of solar controller recovery voltage: load output recovery voltage and constant current charging recovery voltage.
 

As development of IOT( Internet of Thing), RFID technology is more and more common in various of industrial applications. Network on Ethernet, essential basic of IOT constructions, is very important part of RFID devices trend. RFID middleware has powerful functions that could manage 100+ RFID readers and antennas, and build bridge between customers application and hardware. However, few RFID company have capability to develop middleware, and moreover, the price is too high for a medium or small project.
Hopeland have pushed an intelligent RFID reader HL7206C9, combination of 4-ports RFID reader, raspberry pi computer, and RFID middleware. The reader is developed under Impinj R2000 chipset platform, with raspbian GNU/Linux 8.0 operation system, could control max 10 sets of other RFID readers at the same time. It also have 1G RAM and 16G ROM, support off-line working.

In general, we will be solar photovoltaic power generation system is divided into off-grid system, and network systems, hybrid systems. When users choose to install solar photovoltaic power generation system, you must first confirm the use of off-grid power generation or grid-connected power generation, the use of three functions are not the same, the system is not the same equipment, the cost is also a great difference.
 

1. solar panel (component) selection
Solar cells currently on the market are divided into amorphous silicon and crystalline silicon. Among them, crystalline silicon can be divided into polysilicon and monocrystalline silicon. From the photoelectric conversion efficiency of the three materials are: monocrystalline silicon (up to 17%) > polysilicon (12 ~ 15%) > amorphous silicon (about 5%). Crystalline silicon (monocrystalline silicon and polycrystalline silicon) basically does not produce current in poor light, and amorphous silicon has a weak light (which is less energy in low light). Therefore, in general, it is better to use monocrystalline silicon or polycrystalline silicon solar cell materials, and consider monocrystalline silicon material is expensive, so generally choose polysilicon materials. If a polysilicon solar panel with power of about 250W is selected, a 5KW system requires 20 panels.

Solar power generation is divided into thermal power generation and photovoltaic power generation. Usually said solar power refers to the solar photovoltaic power generation, referred to as "photoelectric". Photovoltaic power generation is a technique that utilizes the photo voltage effect of the semiconductor interface to convert light energy directly into electrical energy. The key component of this technology is solar cells. Solar cells through the series after the package protection can form a large area of the solar cell components, and then with the power controller and other components to form a photovoltaic power generation device.
