Amperes low a lot of voltage ?
Hellp there i ve created a small 70x70 panel that produces 1000+ volts but near zero amperes polymetre shows 0.5MA this is per second? Or hour and second how i can rise the amperes up to 1 ampere? Thank you in advance. A lot of voltages and 0.5MA

Is 1000v useful to you?
If not then connect the cells differently to give you something easier to handle. Most have an upper limit of 400V beyond which you are creating more of an insulation risk than a current handling issue.
If you are just wiring up your own panel - keep it simple and aim for 10-18v output. suitable for battery charging.

Depend on how you connect the panels parallel panels double current

As I said the 1100 voltage is in 70x70cm panel is a very small one with huge voltage power BUT the 0.5mA

Sounds like your 1000 v source has an internal impedance of 2 meg ohms.

Is it a "solar panel"?
Cells in series, increases voltage.
Cells in parallel, increases current.

An Amp is a measurement of electrons moving per second.
1 A= 1 coulomb of electrons flowing past a point in 1 second.
1 C=6.24x10^18 electrons.
If you decrease the load resistance to 1KΩ the current will increase to 1A.
It sounds like you are using a Multimeter with an impedance of 2 M.

the unit ampere is equal to charge per second, so the unit is a "per second" measurement. Increasing the amperage (flow of electron charge per second) might be possible by changing the power source or by changing the resistance in the circuit, or both. Hard to give any detail without knowing more about the system.
It is not clear if the current is source-limited or circuit-limited.
Also, I assume you mean mA and not MA,. mega-amps is a lot of current (million amps). I wouldn't touch that circuit if it is putting out mega-amps at 1 kV. Fatality would result.

do you mean 0.5 mA ? MA means mega amperes, millions of amps.
no, it is not per second, it is a value for the current. You cannot increase it without a different circuit.
you could use the 1000 volts at 0.5 mA to charge a high voltage capacitor, which can produce higher currents for brief periods. For example, a 1 µF cap will store 1 mC of charge, which can deliver 1 amp (average) for 1 ms. It would take about 2 s to charge it. Note that 1 µF 1000 volt caps are large and expensive.
Be careful, this is lethal.
One of my past projects was to design a 2000 volt 20 mA programmable supply, not all that difficult.
