Solar grid connect systems supply solar electricity from solar panels to an inverter directly to the household and to the electricity grid if the system is providing more energy than the house needs.
When excess power is supplied to the mains grid the owner receives a credit for that electricity. The amount of the solar energy available to collect from the solar panels depends on the time of year and the time of day.
Although Tasmania is the most southern state in Australia it is still viable to run solar grid connect systems as we have similar amounts of sunlight to Melbourne and Sydney. Solar panel grid connect systems are most effective when used in conjunction with highly efficient heating and hot water systems.
Tas Energy Savers provide free in home quotes to ensure you get the best system for your situation rather than just the cheapest system available. We have many years experience installing quality solar systems designed for the Tasmanian climate that will last much longer than cheap products.
How Solar Power Works
Basically solar panels work by allowing photons (particles of light), to push electrons free from atoms which generates a flow of electricity. The structure of Solar panels is they are made up of smaller units called photovoltaic cells. (Photovoltaic simply means they convert sunlight into electricity.) When a multitude of these cells are linked together they form a solar panel.
Simply put each photovoltaic cell is a sandwich made up of two slices of semi-conducting material, usually silicon, as used in microelectronics.
In order to function, photovoltaic cells need to establish an electric field, an electric field is created when opposite charges are separated. To get this field, manufacturers include other materials in the silicon which gives each slice of the sandwich a positive or negative electrical charge.
Phosphorous is “seeded” into the top layer of silicon, which adds extra electrons, with a negative charge, which causes a subsequent negative electric charge to that layer. Boron is added to the bottom layer, which results in fewer electrons, or a positive charge. This all adds up to an electric field at the junction between the silicon layers. Then, when a photon of sunlight hits an electron and knocks it free, the electric field will push that electron out of the silicon junction.
Metal conductive plates positioned at the sides of the cell collect the electrons and conduct them to wires. This causes the electrons to flow like any other source of electricity.
Why Use Solar Panels In Hobart?
Because the generation of electricity from the solar panels only requires light (not heat) to function it means that they are very suited to the Hobart and Tasmanian climate. Generally speaking Hobart has many fine days during the year which means great hours of sunlight exposure for the solar panels to function.
With a professional assessment of your property you can make the informed choice as to the system that is right for you, solar power is always getting more affordable to install as the production of the systems is becoming more refined.
Tas Energy Savers are Hobart’s leader in the installation of solar panel systems and inverters.
