Nope. It's a 12V panel and comes with "Positive and negative leads equipped with MC4 connectors"

If you wanted to plug in an item with a 120V household plug you would also need an inverter, and maybe a battery for when clouds pass.

I just recently bought a 100 Watts solar panel from Costco (paid $120, but it came with a small solar battery charger module for 12V battery). At first I used it to hook up to and old car battery to use as a (12v) buffer hooking up an attic fan, but since I was experimenting to find the best and inexpensive solution, I finally settled on a DC-DC buck converter ($5) like this:

https://www.ebay.com/itm/DC-DC-CC...2602817113

I adjusted the power terminals to come in from the solar panel (17.5v) > buck converter > 12V (output to fan) and it has eliminated my need to buy expensive deep cycle batteries for power storage.

If you don't need power storage and just want to use the harvested power right away (like what I'm doing), this can help.

It becomes an electrical problem at that point. Higher wattage panels will be larger and probably need additional electrical components. You could always just hook these up in parallel to achieve a higher wattage?

No, just the panels. Look into the Goal Zero line for turn-key solutions. They are very pricey for their components, but the value is in the ready-to-go turn-key solution.

Obviously this needs a charge controller and battery (and inverter if you plan to connect AC devices) to be actually useful (even my puny 10W panel needs the first two to do anything). Do they sell kits that include these, and how much should they cost?

FWIW, the battery is obviously needed to store surplus power for when it's overcast or dark out sunlight it otherwise not able to reach the panel, and to assure a steady supply of power no matter what conditions are like. And a charge controller is an essential part of any real-world solar power solution, converting the panel's output into a regulated power supply to properly charge the battery (ideally extracting the maximal power possible at any given time and whatever the conditions), and then converting the battery's stored energy to a usable well-regulated output, e.g. 5V USB, 12V, or, with the additional of an inverter, 120V AC.

How much is the controller and necessary wiring? Renogy 100w out of the box solutions run $160 regular price and have a good reputation, is this really that great of a deal? Also for comparison HF's newish 100w full kit is as low as $150 after 25% coupon. Not sure how the quality of this brand compares to either though.

Any good sites to get pricing on solar panels in 60 cell or 72 cell range?

mono and poly are so close it doesnt matter. 100w is 100w. besides, "a little more" is typically $30-$40 more. thats 33% - 44% more, lol.
