I don’t want to spend a fortune, maybe talking like over $ 200 but I would like to power my computer, the monitor, my tv, and a small fridge.
I looked up the price on some but it does not make any sense to me because it says that it has reached the price of less than $ 1 per watt but if I look up a 120 watt solar panel it is $ 560 dollars. Why would it not be $ 120 because they said $ 1 a watt.
Where would be the best place to buy the cheapest solar panels?

The solar panel itself might cost less than a dollar a watt but the devices needed to convert and store the electricity are never mentioned. They cost more.
. The panel you memtioned is in the general market range.
i buy 45 watt kits which include charge controller … Cheasy frame and a couple of other items between $ 160 to 240, depending on when I buy and if on sale or not from harbor freight. Then I also have large deep cycle batterys (pricey) to hold my power fed to my inverter i do it this way so i can pay as i can afford toadd to my system.
you need to add up the total wattage you require before you can know how much of a system you need. Good luck!
You are probably better off buying solar cells and making your own solar panel. That is what I plan to do. Figure in the cost of batteries, an inverter, and maybe a charge controller. You will need to test the solar panels to make sure you have enough power to power up everything you have. If not, make additional solar panels, and connect them together. Nevertheless, I think it still might cost way over $ 200, but I think it is the cheapest way to go.
Today the lowest cost is more like $ 3 a watt. And you need to shop well to get it that cheap. The solar industry hopes to drive the cost down to $ 1 a watt with the new thin film technology, but production volumes are still too low with that new technology for the market prices to come down. Their goal is to hit $ 1 a watt within 5 years.
The first thing you need to do is look at the power needs of those things. Add up the power (Watts) to run all of those things at the same time.
Then you’re also in trouble if you plan to run those things when it’s not peak sunlight, so you’ll need some battery setup.
And some appropriate fuses and diodes and a controller of some kind to protect your panels and the things you are powering.
It would take a bit of physics and electrical knowledge to do this and do it safely.
I built a car that ran off of solar energy in a college project last school year. We had a bank of Kyocera 50 Watt panels that cost 250 each. So, you won’t be able to do this for under 200, sorry.
If you wanted to spend more I could figure out everything you needed for you, but money will be a problem. And I don’t know if it will really be cost effective.

I fished around a ton and came across Arosa Energy – I was looking for cheap, but also wanted to deal with honest, helpful people. They were really amazing, got me great rebates, and helped me figure out some stuff. I would recommend them if your serious about it…
