Yesterday before the rain set in, we installed this 6.08kW Grid Connect Solar System on a kindergarten in Westcourt. This system comprises 19x GCL P6/72 320W solar panels and the new ABB UNO DM-5.0-TL-PLUS Italian designed and manufactured inverter.
For commercial systems like this there is no extra cost in most cases, but the savings can be far greater depending on which tariff you are on. With the solar feed-in-tariff at 10.1c per kilowatt hour it is far more beneficial for your solar energy to be consumed, rather than feeding it in to the grid, saving you as much as 51c per kilowatt hour.
Commercial solar systems are far more beneficial in this respect as most commercial power usage is during daylight hours when your system is producing power, negating the need to buy your power from the grid.
Recently we have been doing quite a lot of large, commercial systems and have great buying power for good quality products. We are consistently the cheapest in North Queensland for high quality commercial systems.
