Your first mistake was that you did not buy the pet fish first, before building the pond.

You have done this absolutely backwards.
First, you buy the most efficient pump for your size pond. Take into account the required volume and lift, and any plumbing restrictions or strainers.
Decide how many hours a day the pump needs to run.
calculate the energy required. 250W pump x 6 hours =1500watt hours.

Decision time. 200' of 16 ga extension cord = $90 or
600w of solar panels, charge controller, battery, inverter, PV panel mount, raintight shed for the gear. $5,000

I already bought the solar panel 40watt and a solar charge controller
this is the solar panel

This is the solar charge controller

Huge mistake, not likely you can use any of it.

He could use that panel and charge controller with a 30Ah battery and run some low wattage DC lights around the pond

I am just going to get a 12-24v dc pump , since the pond already has an ac pump...I just wanted to add a solar feature and I learnt yo can connect the 12-24v pump directly to the solar panel

Depending on the pump some DC motors will not work correctly (or continuously) just connected to the panel.

There are DC Solar pumps that work directly from a solar panel without batteries but most have some type of controller that keeps the pump safe.
