How can I make or buy a solar powered grounded outdoor electrical outlet?

I would like to have a few outdoor outlets that can power some of my outdoor tools and a fountain. Can I do this with one of those small solar modules? Or does this already exist? I’ve seen small solar panels along the highway that power the emergency phones. Would something like this work? Unfortunately, [...]

Why dont electricity companies use our roof (solar) to generate electrcity to contribute to the national grid?

I live in NZ where nuclear electricity generation is not an option and where solutions have to be found that are sustainable. Most of our electricity is generated by hydro-electric dams but as we move towards needing more electricity (it seems minimising use is in the too-hard basket) we are being asked to consider "solutions" [...]

how do I clean my photovoltaic (solar) panels?

I have flat solar panels (like this http://www.sanyo.com/industrial/solar/index.cfm?productID=1232) mounted on my roof. Even after hosing them down, they still have a fine coating of pollen, etc. I really don’t want to get onto the roof to clean them, so is there anything out there that will help me get them clean from the ground? Or [...]

What is best voltage for solar system array – residential 220v?

my house is 220 volts. Since 12 volt solar panels and 12 volt batterys are so available, for some reason I decided to group 4 panels into 48 volts and 4 batteries into a 48 volt battery and store the energy and when needed convert 48 volts to 220 volts and use it. Am I [...]
