for the solar panel, i bring it under the direct sun, and it produce 10 v withoutregulator. with regulator, it shows 5 v. means, approximately half of the voltage of solar panel.. and power  produce should also approx half of it..

[Upen Ganesh]

"Cats and Dogs can be repelled using 22-25 kHz. Insects like mosquitoes, House fly, Fleas etc responds to 38-44 kHz."
