How to build a solar powered shed?
What components/setup would you recommend to power a shed in Las Vegas area? I plan to power a 32″ LCD TV, laptop computer, and small tools such as a soldering iron or a battery charger for power tools. (Not running power tools directly from the solar batteries).
I understand I will need an inverter, but what would size would be needed? How many batteries?
Most of what I need power for will be to charge batteries (cell phone, laptop, cordless drill) while running other things directly from the inverter (LCD TV, possibly Play Station 3, small desk fan).
-The A/C unit will run off the house grid so no factor there.
Last thing is, would you reccomend a small generator and how easy is that to add to you power setup?
You would probably be better off connecting the shed and solar panels to the grid via a grid-tied inverter. You will be able to use state rebates which will significantly reduce the cost of the system. You can look up state rebates here: http://www.dsireusa.org/
You will need to use a licensed installer to install the system with the inverter, and they will help you size the system. It will be a lot easier than doing all the math yourself! Also, with a grid-tied system, you will not need to worry about using large appliances or tools, b/c the inverter will just draw from the grid when the load is more than the solar panels are producing.
With a grid-tied system, you can sell any excess electricity back to the grid, which will increase your return on investment. Plus, you will not need to spend any extra money on batteries or on a back up generator.
You can use google to find a contractor. Choose one that has lots of experience, that is close to your home, and that will give you an on-site consultation for free.
