the 5 most frequently asked off grid / Stand alone Solar Questions
Q: Am I able run an air-conditioner in an off grid home?
A: Yes! Today's air-conditions such as inverter split systems are relatively efficient. As we size all our panel arrays to have enough output for winter, you'll have extra output during the summer months to cool the rooms down during the day. If you want to run it through the night, for heating in winter or in Northern Australia where your summers = the rainy season, then we can always upgrade system size to cope.
Q: Is Off Grid Power, Cheaper than connecting to the Power grid, and paying for power?
A: Even if mains power runs along the front of your property, our customers are being quoted tens of thousands of dollars to have power connected to their house and shed. Some of our customer have been quoted $100k once transformers and power poles are required, which is more expensive than one of our largest systems. For a fraction of this an off grid system can be designed,supplied and installed. On top of this you won't have to pay any connection or on-going power bills. Off-grid systems are now virtually maintenance free with panels lasting over 20 years and batteries designed to last 10 - 15 years.
Q: What is different about living off the grid, to Living on the grid?
A: Very little, systems are seamless. We can even automate generator start-up to ensure the generator will kick-in to charge batteries and supply your household loads when required. We install systems fully monitored; allowing you to know how much power is being produced, used and stored in the batteries at any time. If possible the use of gas for cooking and hot-water will take the big power consumers out of the picture, reducing system requirements and price drastically. Once customers understand capabilities of the system they purchased and what appliances have high power consumption's they can live like they would in town.
Q: What is the best type of hot-water system for off grid?
Q : Can i live "Off- Grid", if i live in the city?
A: Electric hot-water systems can be the biggest power consumer in a normal household. Going with instant gas hot water or solar hot-water with a gas boost are the best options by far if you want to reduce the system size and cost. Solar hot-water with an electric boost is the second best option with most customers find the boost is very rarely required in the Northern states of Australia. Powering an electric hot-water system is also possible with off-grid power supplies however we do need to size accordingly.
A: It is possible to go hybrid or totally off grid in the city, however as you already have mains power connected it's not as financially viable compared to a property with no power present. Hybrid/grid connected battery back-up systems using Lithium ION technologies such as Tesla and LG chem generally still have a pay-back period of around 10 yrs with batteries replacement required around the same time. If your power consumption is low e.g. 10 kWh or under then totally off-grid still may be viable. Not all decisions are financially driven, if you have the desire to not pay electricity companies any more money, or if your driven by environmental concerns, there is nothing stopping your from going with stand-alone power.
