Smart module Smart module Smart modules are a type of solar panel that has a power optimizer embedded into the solar module at the time of manufacturing. Typically the power optimizer is embedded in the junction box of the solar module. Power optimizers attached to the frame of a solar module, or connected to the photovoltaic circuit through a connector, are not properly considered smart modules. Smart modules are different from traditional solar panels because the power electronics embedded in the module offers enhanced functionality such as panel-level maximum power point tracking, monitoring, and enhanced safety. Solar panel installers saw significant growth
Perl module is added to (and in rare occasions taken away from) each new release. For this reason it is important for a module author to be aware what features they're making use of and what the minimum required version of perl is. The code on this page requires perl 5.6.0 which is considered rather old by now. What follows are examples of "Hello, World" implemented in different styles of modules. It must be understood that a module is not necessary in Perl; functions and code can be defined and used anywhere. This is just for example purposes. Contrast with Java where
