It is always better to know a little about the products you are planing to use. Some of the
solar products provided by Oy Not will be setting around your home for 20 to 40 years so a
little extra information can’t hurt.
Ever wondered what they mean with some of the solar products keywords: Vmp or Voc or
Imp or even Isc on solar panels?
- Watt: Standard unit rating of module power output (W). Watts = amps times volts. - Volt: Standard unit of electrical potential (V) or measure of the strength of an electrical source. - Amp: A measure of current (A) or quantity of electricity. - Vmp: Maximum power available voltage. - Voc: Open circuit voltage. An open circuit occurs when contacts, switches or similar devices
are open and prevent the flow of current. Used to determine if the module is within the
maximum voltage of an inverter. - Imp: Maximum available current. Determines maximum current an array can deliver at
optimum conditions. - Isc: Short circuit current. A short circuit occurs when there is an improper connection that
interrupts an electrical circuit. Used to determine appropriate fuse sizes.
