Hello reader, this is a case study about an off-grid solar wind hybrid system in Australia. The system is composed of a 2kw solar array + 3kw wind turbine system with batteries. Since this is a stand-alone house in the countryside, there is no city grid power connection or diesel generator. The suitable idea, therefore, is 100% power by solar and wind power.
The off-grid solar wind hybrid system is in the daytime, solar power will be kept in the battery bank, and if the wind speeds are good enough, the wind power will charge the battery bank 24hrs. And battery bank supplies power via a hybrid inverter when needed.
Using an off-grid solar wind hybrid system means no downtime or blackout because the system provides a 24hrs round-the-clock power supply. This is because the off-grid solar wind hybrid system has a battery that acts as a power bank for use at night.
Reliable and convenient power supply - The system is fully integrated so that at no point will the battery have no backup stored-up power. When there is no sun, the windmill also supplies extra power.
This off-grid system makes good use of naturally occurring resources to generate electricity. Also, there is absolutely no noise pollution associated with the use of an off-grid solar wind hybrid system, as in the case of using most diesel generators.
The off-grid solar wind hybrid system offers a steady power supply that ensures that the electronics in the house are protected from power surges. Using grid power can sometimes be unstable with high and low unpredictable voltage supply, and this can cause the house electronics to suffer from power surges and get spoilt, incurring costs.
The off-grid solar wind hybrid system works perfectly because of the seaside location, with good sunshine exposure and good wind throughout the day.
Mr. Hennie feels contented with the choice of an off-grid solar wind hybrid system because of the following reasons;
The sunshine(solar) and the wind in this location are pretty good; therefore, there is a reliable and constant power supply, and the battery bank is always full. At no time does he experience any downtimes and blackouts, and therefore he can relax in the house undisrupted by power failures.
Off-grid solar wind hybrid system is very stable with a stable supply of electricity which means that all the appliances are protected from any power failures and power surges. Mr. Hennie likes the fact that he does not necessarily need any surge protector to protect his appliances against damages caused by high voltages.
Low maintenance cost- after the deployment of an off-grid solar wind hybrid system, the cost of maintaining the system is close to zero. Mr. Hennie enjoys the fact that he does not incur any further costs like he would if he opted for grid power or a diesel generator.
Due to the fact that wind and solar work interchangeably, the system is fully integrated with enough power generation from both wind and solar, as well as a power storage bank in case there is not enough wind or solar during the day or at night.
Mr. Hennie enjoys the quietness at his home when using his off-grid solar wind hybrid system, which would not be the same if he opted for a diesel generator that is always noisy when in use.
Finally, Mr. Hennie appreciates the fact that even though he lives far away from the city, he can still access electricity and have his phone charged, enjoy his television shows and enjoy the lighting in the comfort of his home with the off-grid solar wind hybrid system.
