Thank you Sloweather.
Finally i see the solar energy is expensive yet everywhere .
And i beleive it is not absolutely free ,the day is free ,but the night we need bateries and the bateries it have high cost to change it every 3-5 years (here to Greece one batery closed type 12 volt - 200 AH it cost 380 euro or 528 dollars). Do you understand to have 10-15 bateries this type parallel ,and you change it every 3-5 years how big is the cost .And all this if someone he want to have solar energy inside all house ,and do not need the electricity company ,but this is a very high cost ,and my personal opinion is the solar energy is only yet for helpful the main electricity power .
Yet the cost for solar panels ,bateries is high ,and the wind generator is more expensive ,and it want areas with strong wind over to 25 km/h for work .
I like the idea for solar-wind energy but yet it have high cost the all equipment.
