10 Watt Solar Charger

I have a playstation PSP charger that is 5v 2A, so it takes 10 watts.

I have several small solar panels that put out 1 watt a piece and are 4 volts, 250mA

how can I get my 10 watts to be 5v 2A instead of 4v 250mA?...

Stack your panels in series by pairs so they are putting out 8 volts, then put 8 pairs in parallel. Finally, use a 3-terminal 5 volt regulator to get the voltage right. A pair of 7805 regulators (Radio Shack or mouser.com) in parallel will do the...

Here's a 10 watt photovoltaic charger with a 12 Ah battery. You can do quite a bit with this baby. It's based on a Popular Science DIY ...

I have a 10 inch portable tv and the battery only last a couple of hours. I was wondering how much power it would take to run my tv. I want to purchase a lightweight solar charger and i am not sure what i would need. the Tv requires 24 watt to run...

Your TV needs at least 24W to operate, that means you will need 24W solar panel or more if you want to run the TV in real time while the sun is out. Then you will need to wire charge controller between the panel and your TV to regulate the...

this is for a non profit school , they are going to use mostly (10) desk top computers (5) eggs incubator and a small medicine fridge. i already purchased a 5000 watts inverter w/ charger, we have a gas generator but it's a long trip to get fuel....

you could take the effort to add up the power consumption of all those items, you can do it a lot easier than I can.

Why did you pick 5000 watts, it seems high, but I have no idea what an egg incubator uses. No lights in your...

Just thinking thing over. Want to install a 120 volt AC to12 volt DC converter, as the ones found in most RV's. The 12 volt would be used power 12 volt light fixtures as one found in RV's, and Marine crafts. The 12 volts could be used with a solar...

Just not very realistic.
You're talking about 120W. of incandescent light for
an entire house.
It's about enough for one large room.
A refrigerator will draw about 800W. while running,
a microwave or toaster 1200

I am planning to convert a retired school bus for a road trip to Burning Man, and i am not planning to do a full camperization, just removing the seats, popping a bed at the end in front of the exit, bringing in a basic couch, and building a short...

The solar panel will work nicely to keep the batteries topped, but will probably not be able to run much directly. Look-up solar panels, and calculate the wattage they can produce compared the the square feet of surface, & I think you'll see...
