Product Name: | 180-Watt Semi-Flex Crystalline Solar Panel for 12-Volt Charging |
Product Description: | Wafer thin, lightweight and can mold to a curved surface. These Semi-Flexible Solar Panels are made of the high efficiency mono-crystalline solar cells and strong enough to be walked on. They are weather, water and corrosion resistant making them a perfect option for marine applications, RVs, camping and emergency back-up, These Panels can continuously recharge your 12-Volt batteries (not included) with the power of the sun. Light enough to mount on a window with suction cups and durable enough to mount permanently outdoors on a range of vehicles. |

I would not connect these to a battery directly. Make sure your controller can handle this VOC.
first things that come to mind are:
-'Float Charging' Battery(s). In-often used automobile/RV, backup-power inverter, DC lighting, etc.
-Camping/traveling. Power and charge personal electronics. (@ half the panel's rated wattage and subtracting out some for conversion losses, it should should still be more than enough to power any laptop that uses a ~65W or less power supply.
The 'cheapest and simplest' setup would (probably) be a Lead Acid battery* connected to the solar panel, and a 'cigarette-lighter socket car charger' for your devices connected to the battery. IIRC, (without known exceptions) you do not want to directly power anything other than 'power storage devices'.
Edit: The specs on Home Depot say 15V. At least on the Power Wheelchair AGMs I have, that would probably be perfectly safe to direct connect to. Just, don't leave it hooked up during night.
*Note: Automotive-common 'Starting, Lighting, Ignition' flooded-cell batteries have different discharge curves and charging voltages than 'Sealed' AGM and 'Gel' 'Deep Cycle' batteries (as commonly used in Golf Carts, Power Wheelchairs, etc.).
Flooded Lead Acids will also off-gas potentially explosive Hydroxy if overcharged for long periods. One can pedantically figure out the details; the data is readily available online. However for short-term use (in a well-ventilated area), said details aren't terribly important.
If you're making a long-term use appliance out of it, you'll definitely want to find out the precise voltages supplied from the panel. *Or* just use a proper 'solar battery charger' and not worry.

The second and fifth pictures give some ideas. Boats and RVs are probably the biggest uses, since these are semi-flex they don't have an aluminum frame around it. Good if your boat or RV is a bit round on top, but not as great for mounting on your home roof.

How about in array?

If you want to use four panels in series you will end up with a input voltage of near 100, so then an MMPT would be necessary to step down the voltage for an array of 12V batteries. If you wanted to use one panel to charge a 48V ebike battery, then you would need MMPT. In short, if the delta between the panel voltage and the battery voltage is high, then you need MMPT.
Yes and it comes with the plug for it it also will power your house for a week in the moonlight.
