I want to make a solar power generator for ac use not dc use, how long will it last if iam running a total of 1600 watts ? I was planning on making one with 8 batteries.
thanks
any websites that explain this would be greatly...


The question is not too clear, as solar chargers are in fact d/c power as is the batteries they charge. To get a/c power from the system you will need an "inverter", and they come in various sizes, watts that is.

What kind of solar power setup would I need to power a single room's energy needs?
tompkins county gets most of its electricity from this coal plant

I live in the basement of a house and would like to run my room on solar power. I have two power strips that run a TV and DVD player, a laptop, printer and two external hard drives and I would need to use a couple floor lamps in the room as well....


Let me just say, the cost would be too much to be worthwhile. It appears you would need at least 750 watts. if you wanted to use the electrical things at night too, the system would have to deliver that much power for the equipment, and more to...

Could Solar Power work more effectively if the solar rays were magnified?
PLUS

If we focused the sun's energy like a magnifying glass does into the solar panels, would this generate more power at all?


No, it would not. If the magnifying glass is the same area as the solar collectors, then it would be the same amount of energy the solar collectors would be gathering without the magnifying glass.

In a way it would be cheaper,...

I assume it is a DC motor. You should have DC voltage coming out of the solar cell (For example 10V). You could use a transistor to switch the voltage on and off, then filter the output with an RC filter. You will have to choose the right RC time...

    • Enphase raises another $8 million

    Enphase, founded in 2006, makes microinverters that boost the output of solar power systems.

    Microinverters attach to individual solar modules and convert DC to AC power. The Enphase system is more efficient than conventional inverters, increasing energy production up to 25 percent, the company said.

    Enphase revealed the private equity deal last week in a filing with U.S. securities regulators. In June, the company said it's planning to go public with an initial stock offering worth up to $100 million.

    But the IPO hasn't happened yet, and no date or share price have been set. Venture-backed technology startups are waiting for stock markets to improve before going public, according to Wall Street analysts.

    Bellefonte looks at solar power - Local | Centre Daily Times ...

    BELLEFONTE — The sun shining on Bellefonte could mean more than a picnic at Talleyrand Park.

    After analysis by SunDirected, a solar energy company in State College, Bellefonte could save close to $100,000 a year on its electric bill if it placed solar panels on part of the landfill property on Musser Lane.

    Michael Shadow, a solar energy specialist with the company, gave Borough Council several project options, along with their price tags, during Monday night’s work session.

    The Musser Lane solar farm would start at 1 megawatt, which would take up about four acres of the 15 to 20 at the property. Shadow said the borough would need about a 5.6 megawatt system to offset 100 percent of its electricity usage, which he called a “humongous project.”
