Dont know myself!
I do understand that wind and solar both have their regions of application. If you live where its cloudier but have loads of wind like I do, wind based power generation is super.
But if your in an area with low winds or a urban environment you cant put up a wind generator or get much out of it. Thats where the solar panels have a solid advantage!
Plus there are far different operating characteristics in a wind based system Vs a solar panel system. Solar panels can be disconnected from a load and have nothing happen.
While a wind generator could possibly spin itself to pieces!
Solar only works most efficiently during sunny days. Wind power can work 24 hours a day.
There are also trade offs in the designs too! Solar panel based power systems are fairly expensive even when you build them yourself. Wind power is capable of much higher power per square unit of measure. And the system can easily be made from simple components and still work with fair average efficiency.
I am not 100% all wind or all solar! I know they both have areas of advantage and disadvantage.
As far as control systems go, wind has just as many control systems available as solar! However wind power generally uses some form of shunt voltage regulation.
Wind controllers dump the excess power away from the batteries in order to keep the load on the generator. Thats where I assumed solar did it the same but apparently it does not!
I played around and experimented with battery based power storage for years. I got sick of all of the battery maintenance and the need for the charge control and what not! Plus only having what was stored in the batteries available for power. And when there was more power available than what the batteries could hold I could not do anything with it but make wasted heat!
On top of all of that the having to run anything that required 120 volts AC power needed to have an inverter of some sort and was still limited to what that inverter could put out!
Well you know that part!
It was my actual searching for a bigger better inverter and storage system that lead to my doing the research and development work on grid tying the power generation sources to my utility power.
Once I got the grid tie bugs figured out, the charge control system, batteries, and inverters got the boot and I never looked back with any serious intentions!
You know any one that wants to buy ten 6 volt 200 Ah Exide industrial storage batteries? $25 each you haul them! 8 are still in great shape! two have cracked cells at one end. The wood cabinet is included!
they will be cleaned up and tested before pickup and I will load them too!
(The salvage dealers will pay $25 each too so they wont get any cheaper.)
I am just simply trying to understand a form of alternative power that I currently do not have much applied knowledge in. Nothing more!
