New way to produce power  

Low carbon power refers to power that uses smaller amounts of carbon, such as hydrogen, natural gas and solar power, rather than traditional carbon based fuels, such as wood, coal, gas, and oil. The burning of these conventional fuels produces high amounts of carbon dioxide adding to the greenhouse gases. Low carbon power therefore, is a cleaner, greener, way to produce power.

Energy problems 

Societies today rely on sources of external energy for the manufacture of goods and the delivery of services. This energy allows us to live in diverse climatic settings, in large populations, and often in controlled environments. The level of dependence on those sources varies according to the climate, level of comfort, and general needs of a community.  

Energy is expensive to acquire yet easy to waste, and using it for electricity and fuel takes its toll on the planet. To date, the greatest sources of energy have been fossil fuels, of which the three most commonly used are: coal, petroleum and natural gas. Unfortunately, the combustion of fossil fuels releases pollution into the atmosphere and fossil fuels are non-renewable… their availability will decline. 

Sinotech Solar's solution to this is in creating innovative products which are solar powered. Solar power is the technology of harnessing and producing usable energy from the sun's light and is already used in a number of ways such as heating, electricity generation, and desalination of seawater.

The 89 petawatts of sunlight that reaches the earth's surface far exceeds the 15 terawatts of average power consumed by humans. Solar electric generation has the highest power density of the renewable energies, is pollution free, needs little or no maintenance after initial set-up and is increasingly economically competitive. 

Solar cells, also known as photovoltaic (PV) cells, are panels that use the PV effect of semiconductors to produce electricity directly from sunlight. Historically the use of solar cells has been limited due to expensive manufacturing costs and relatively low solar cell efficiency. More recently, advances in research and scale of production have both reduced costs and increased efficiency, allowing for many varied and innovative uses.  

How does solar work?  

Photovoltaic cells generate electrical energy from sunlight and are typically used on a small to medium scale, although increasingly larger arrays of solar modules are being used for pure electricity generation feeding into normal grid supply. Up to 20% of solar energy available at the earth's surface can be captured by these cells. 

Most cells are made of silicon which acts as a semiconductor, absorbing some of the light and then converting it. Unlike pure silicon, where negatively charged particles are locked in the structure and cannot move, silicon in a solar cell, which is a combination of p type and n type, has a deliberate addition of impurities so that the electrons, are free to move and carry electricity. When light hits the solar cell, the electrons move, creating an electric current that can be drawn off and used.
