Solar Energy

Solar Energy

We recognise that solar is one of the best technologies available to decrease a organisation demand on the grid and intern reduce operating costs.

Solar enables energy to be produced at the site where it is needed, as opposed to paying for the transmission of power over great distances. The Intergovernmental Panel on Climate Change (IPCC) has said that solar is, “by a large magnitude”, the most feasible technology that will reduce emissions made by producing electricity. This is of paramount importance because decreasing emissions should be the key outcome of any technology that produces electricity.

Why go solar and why go solar now?

Several reasons: solar energy can decrease or eliminate your energy bill, become self-sufficient, decrease your environmental foot print, help supply power to your neighbouring community, use it to charge your Electric Vehicle (EV) and become an ambassador for a safer, cleaner Australia. What more could you want out of an emerging technology?

Since solar energy inception in 1981, Aleksandr Stoletov produces the first solar cell, it has undergone drastic changes in not only price and efficiency but it has become a household name. It has taken more than 125 years since its emergence to reach the dizzying low prices we now take for granted. In 1977 the price of solar panels was 76 US$/W, this has since decreased 250 fold to 0.3 US$/W and it is set to decrease further. Unlike limited fossil fuels, which become more expensive as demand increases, solar panels decrease in price as demand increases. While price is a good indicator of the adoptability of technology it is not the only factor to consider. The Intergovernmental Panel on Climate Change (IPCC) has said that solar is, “by a large magnitude”, the most feasible technology that will reduce emissions made by producing electricity. This is of paramount importance because decreasing emissions should be the key outcome of any technology that produces electricity. If we are to weather the slowly encroaching storm that is climate change we need to take drastic measures and solar is without a doubt a key contender in helping us do so.

PV or photovoltaic solar panels work by harvesting light from the sun. They convert the light energy produced by the sun into useable electrical energy. The solar panel then sends energy to an inverter. An inverter is an electronic device that converts DC power, that which is produced by the solar panel, to AC power. The reason for this conversion is that DC power can but is not typically used for powering homes. It is first necessary to convert the electricity in order to power lights and appliances. However, before converting the energy a decision must be made whether to store the energy. The problem is that solar energy is only produced when the sun is active, after the sun sets no electricity is produced. So for a typical home, where a large portion of their daily energy requirements are at night, solar alone is of little assistance. The DC power from the solar panels can be directly used to charge batteries, for example, during the day time and then the batteries can be used to service the night time loads such as kettles, TV’s, fridges, etc.

Here at Greenwood Solutions our “go to” technology is without a doubt solar energy. Solar energy is not only good at decreasing emissions and supplying power but it is easy, simple and fast to install. This makes it ideal for our entire range of services, from small residential installations to large scale solar farms. The principles are the same no matter the job.
