Solar Panel Calculator
What are the important values in solar panel system?
- Maximum solar panel system watts. What is the rating needed for the inverter or regulator?
- Maximum solar panel system voltage. Is the total voltage suitable for maximum efficiency?
- Maximum solar panel system current. What is the cabling current rating required?
- Total solar panel area. Do you have enough area to mount the solar panels with appropriate aspect?
- Total solar panel system width. This information can be used for mounting hardware specifications.
Use the solar panel calculator to work out the above information.
