Summary Description. Assemble, install, or maintain solar photovoltaic (PV) systems on roofs or other structures in compliance with site assessment and schematics. May include measuring, cutting, assembling, and bolting structural framing and solar modules. May perform minor electrical work such as current checks.
IFERROR(value, value_if_error) The IFERROR function syntax has the following arguments: Value Required. The argument that is checked for an error. Value_if_error Required. The value to return if the formula evaluates to an error.
1 A consequence of this is that although loop conditions (if, while and the exit condition in for) in Java and C++ both expect a boolean expression, code such as if(a = 5) will cause a compile error in Java because there is no implicit narrowing conversion from int to boolean.
