Measuring PV output power w current sensor/ Voltage divider + displaying on LCD

i have no clue what are the types of current sensors available

Pick a couple of vendors for Arduino'ish stuff... Maybe Adafruit.com and Sparkfun.com
Look over the voltage/current stuff.

Research what others are doing:

Maybe search this forum:

Start with a piece of paper or Excel.

  • How many analog inputs
  • How many digital inputs
  • How many digital outputs
  • How many digital outputs requiring drivers (relays, FETs, etc.)
  • What kind of display? How many outputs are required?
  • How many voltages? 5V, 3.3V, others?

Decide on the Arduino platform. Find sample code for the sensors. Purchase, Assemble, Program.
