Frequently asked questions
How do I get a higher voltage or current?
Connect panels in series to add their voltages while the current stays the same, or in parallel to add their currents while the voltage stays the same.
Can I connect it directly to a battery?
Direct connection is not recommended. Use a charge controller or regulator suited to your battery type, so the battery is not overcharged and the panel output is controlled.
