In my opinion I am thinking that the kind of batteries to handle megawatts capacity for such storage may be costly hence power electronics devices may still be the viable option for now. Am just saying.

The image of a farm with a wind turbine whooshing through the air with cattle milling about underneath grazing the grass is a common one, but more and more Australian landowners are also are opting to use portions of their land to generate energy from the sun; commercial solar power is becoming an increasing popular option in regional Australia.

Solar Choice and its UK subsidiary Solar Selections have provided tender management services on a number of large-scale and commercial solar power projects, including solar farms in regional Australia and the UK. The Solar Choice management team's experience and knowledge enable us to provide impartial advice on which solar system components are best-suited to a client's needs, and at what price.

With even a moderately sized plot of land, a landowner stands to reap the economic benefits of having a solar farm installed on part of their property. There are a number of government incentive mechanisms for solar power available that have been put in place to encourage the uptake of residential and commercial solar power and other forms of renewable energy. Returns will vary depending on the Solar Feed-in Tariff scheme available in your state, but the Federal government's Enhanced Renewable Energy Target Scheme provides a means for subsidies on large-scale solar power installations across the nation in the form of Large-scale Generation Certificates (LGCs)

The wind energy is transformation from solar energy because the sun shines the earth, capacity variance of wind and solar energy is tremendous because of the variety of weather condition. Wind energy and solar energy can be utilized complementary in most countries. Combining wind farms with solar thermal power plants will result in matching the utility load better than with wind or solar alone. Although the solar thermal power plant will usually perform better during the afternoon than the wind farm, the wind farm will perform better in the evening when the utility load will still be high. Combining solar thermal power plants with wind farms will also improve the seasonal match of utility load compared to just using wind farms. In principle, the day the utility peak load occurs is always on a hot day, and solar thermal power generation will always be high on that day while most likely the wind farm during the afternoon peak will either be operating at a low capacity or not at all during the hours of peak loading.

Although combining solar thermal power plants with wind farms will lower the overall capacity factor during the year (as compared to using wind by itself), the electricity will be much more valuable to the utility since it will be generated more often when the utility most needs it (e.g. during peak electrical loads). Since the wind and solar energy will be delivered at different times of the day, then the transmission lines will be utilized more efficiently than by either wind or solar alone. By combining wind with solar the percentage of renewable energy in the country’s total generation should be increased since the utility load – renewable energy generated match will be improved and the overall price of electricity should still be low compared to fossil or nuclear energy and their associated externality costs.

Using a Compressed Air Energy Storage (CAES) system with a wind farm to store the excess wind generated electricity during low utility load periods (late night and early morning), and using a well-insulated tank to store the excess heat from the solar thermal power plant during the day should allow the generation of renewable energy to follow the utility loading very well

during most days of the year. Instead of using CAES, another possibility is to use the excess wind generated electricity in the late night and early morning hours to power heaters to heat up the liquid being used in the solar thermal power plant storage system since this system is predicted to be more efficient and economical.

Better not. ① you will increase cost as the present wind turbine layout scheme; ②within solar, risks of grid connection will be increased.

Dear Gideon,

technically, there is no real issue not to do as you described.

Economically, there is a drawback as in case of failure of the DC/AC-stage, both power sources get lost synchronously.

In case you have solar and wind connected to the grid by individual inverters, a failure in one system will only render one source useless.
