For charging phones they can be quite effective. You need a battery to hold the power, charge the phone from that and then a solar panel to keep it topped up.
Ideally a small leisure battery (12v) then use a standard car phone charge via an adapter.
A 20w minimum solar panel ideally, a 50w if space and finances permit it.

A car charger is much cheaper than a solar panel. It will charge the phone faster and more efficiently also.

A solar panel doesn't typically charge the phone at all. It is used to keep a battery topped up that is used to charge the phone.
So speed wise would be almost the same as a car.

this year for the first time we took a solar panel and battery arrangement. We spent under £60 for the set up, on the basis that this was approx half the fee for an electric hook up (very expensive when all you are running is a light and phone chargers!). The battery is a lawnmower battery and the solar panel measures about 30cm by 15cm. We are very limited on car space! We didn't manage to set up a phone charging station, simply because we ran out of time, instead we charged the phone and camera via the car battery. But this small set up comfortably ran the LED light stip. Next year we will have a charging station too, so watch this space!

You cannot run anything from the panels directly.
You rin the TV from your battery and the panels help recharge it.
The problem in the UK is that you may get less than 6 hours worth of sunlight even in August.
Here today its so overcast your probably going to struggle to get 50% capacity from a panel.
So having your 100watt TV on for 3 hours will need a minimum of 6 hours to recharge from a 100w panel.
How many watts does the TV use and how many hours will you be using it?
Any other appliances?

We charge our phones and i-pads directly. Well almost.
connected to the panel we have several car lighter sockets and into those we plug adapters that convert to usb. they convert the voltage and as my panel peaks at 2 amps then everything charges at normal speed, when sunny ore slower if not.
Just check your adapters for their output a mobile will probably only need 1amp max whereas an I-pad is 2amps. Voltage wise idealy an adaptor that will operate upto 24volts although I was using one that stated 12V and it worked fine even though my panel peaks at around 19V
