The product you're referring to is a solar panel advertised as 200 watts, which matches your description.
It seems you're wondering about accessing the battery in an older laptop with a removable battery compartment. You should verify the voltage level. Both of your batteries are rated at 10.6V. Connecting a solar panel rated at 27V/11A directly to this low-voltage battery without a suitable charging system could cause overheating, explosions, or fires. Lithium batteries are particularly hazardous if exposed to air. Modern laptops often have multiple battery connections and smart chargers that regulate charging based on cell voltage and temperature, preventing overcharging. Attempting a direct connection without proper equipment—like safety goggles and gloves—poses serious risks. Older models may use 2, 3, or 4 lithium cells, each contributing a specific voltage (around 3.5V per cell), so understanding the configuration helps assess feasibility. Exercise caution and prioritize safety.
Best of luck sourcing 5 decent batteries for under £100. Buying second hand laptop batteries is a bit of a lottery.
If you buy OEM (genuine) second-hand batteries advertised on eBay, they're often more expensive than brand new pattern part (clone) batteries. OEM laptop batteries from HP, Dell, etc., are usually over £100 each.
You may find that second-hand batteries are getting old and only capable of storing 40 to 60% of their original capacity. If you pick up 5 old batteries with some useful life for £5 each, it might be worth the risk.
You'll still need a charger circuit to convert the voltage coming out of the solar panel to the correct voltage and current for the batteries.
As examples of what you might need, my old Lenovo Thinkpad X250 takes two different batteries:
Here's an external 10.8V 4400mAhr battery for £32.99.

The internal 11.4V 24hr battery is cheaper at £25.99.

You can swap external batteries in a few seconds. Internal batteries require you to disassemble the laptop, which is best done on a workbench.
jackery is the best option until you discover how sharp anker solix are. lol
Have you paid attention to all the bad feedback about the device overheating during mains charging, the lack of a genuine sine wave as advertised, causing damage to equipment, and the seller clearly being untrustworthy? Absolutely not.
What do you think about having wet hands but wearing rubber ducky slippers?
