Wellsee Hybrid solar-wind electricity production
Hybrid solar-wind electricity production is also new to Wellsee. Wellsee currently push such lamp controllers from 10A-30A.
Wellsee Wind/Solar Hybrid light controller (Wellsee Wind/Solar Hybrid intelligent controller)WS-SWC series is a new product which is designed and self-developed by Wuhan WellseeNew Energy Industry Co.,Ltd with advanced control circuit. The new generation wellsee
wind/solar hybrid intelligent light controller is different from other controllers, which is specially designed for wind/solar
hybrid street light in a group of wind power,solar power, this controller also has light control+time control exact timing control
function which can extactly control loads turn on/off time (Optional)
Functions show as below:
Microprocessor intelligent control, exactly control.
Anti-surge protection,short-circuit protection and reversed polarity protection.
Overload protection,Overcharge protection,overdischarge protection.
Turn on light at dask autotmatically and turn off light at dawn automatically according to light intensity.
Temperature compensation function.
Recognize the wind turbine charging voltage and charging current exactly with safe and complete multiple wind turbine brake
protection system.
According to many renewable energy experts, a small "hybrid" electric system that combines wind and solar (photovoltaic)
technologies offers several advantages over either single system
Wind speeds are often low in periods (summer, eventually) when the sun resources are at their best. On the other hand, the
wind is often stronger in seasons (the winter, in many cases…) when there are less sun resources. That can make
solar-wind hybrid solutions an alternative to consider.
When to consider an hybrid solar-wind system
A hybrid renewable energy system utilises two or more energy production methods, usually solar and wind power.
The major advantage of solar / wind hybrid system is that when solar and wind power production are used together, the
reliability of the system is enhanced. Additionally, the size of battery storage can be reduced slightly as there is less reliance
on one method of power production. Often, when there is no sun, there is plenty of wind.
In comparison to solar modules, wind turbines can offer a more favourable dollar per watt ratio. Solar Online Australia's
hybrid systems utilise the industry's leading high quality components to ensure reliable performance and long life.
Our packaged systems are ideally suited to remote homes, schools and other off-grid applications. They can also be retrofitted to existing diesel-generator systems to save on high fuel costs and minimise noise.
We have standard hybrid systems available to meet your power needs. We can also tailor a system to suit should you have
a smaller or larger power requirement.
Our standard hybrid systems incorporate a 300W turbine to produce the bulk of the power. The systems includes 3 to 4 days
battery backup to cater for periods with little wind or sun. With the two methods of power production the battery backup will
generally last longer than the designed backup period as there will almost certainly be some power input from one of the
sources.
Even during the same day, in many regions worldwide or in some periods of the year, there are different and opposite wind
and solar resource patterns. And those different patterns can make the hybrid systems the best option for electricity
production.
The combination
The combination involved on hybrid systems is rather obvious: to get a target goal of, say, 120 kWh of electricity per month
we can use a single 3kW wind turbine (instead of a 6kW one...) and a solar system with a smaller array of modules.
Size and price
An hybrid wind-solar electric system demands an higher initial investment than single larger systems: large wind and solar PV systems are
proportionally cheaper than two smaller systems...
But the hybrid solution is the best option whenever there is a significant improvement in terms of output and efficiency - which happens when the sun and the wind resources have opposite cycles and intensities during the same day or in some
seasons.
Cases when hybrid solar-wind systems aren’t suitable
Obviously, hybrid solutions aren't feasible in urban and suburban environments (unless we consider new and rather
untested urban wind systems) or in non-windy locations.
Besides, hybrid solar-wind solutions are mainly applied to electricity production. In applications as water heating (where solar is widely used)
hybrid solutions don't make direct sense.
Adding an engine generator makes the system more complex, but modern electronic controllers can operate these systems
automatically. An engine generator can also reduce the size of the other components needed for the system. Keep in mind
that the storage capacity must be large enough to supply electrical needs during non-charging periods.
The power production figure is based on an average of 5.6 Peak Sun Hours per day and an average wind speed of 5.4m/s.
Many locations throughout Australia have averages exceeding these figures. The performance of the system will be relative
