I plan to use green energy as well but with wind turbine, solar panel is good but the price per watt produced is too high, between 1~2 euro while the wind turbine come with 0.50~1 euro the watt.
Yo I think wind power has more disadvantages that solar, you need to consider where to build your farm and the wind power because they are less effective once there isn't enough breeze in action, solar panels wins over wind maybe you can find wind Vs solar power online for some comparisons.
