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
Injective module Injective module In mathematics, especially in the area of abstract algebra known as module theory, an injective module is a module "Q" that shares certain desirable properties with the Z-module Q of all rational numbers. Specifically, if "Q" is a submodule of some other module, then it is already a direct summand of that module; also, given a submodule of a module "Y", then any module homomorphism from this submodule to "Q" can be extended to a homomorphism from all of "Y" to "Q". This concept is dual to that of projective modules. Injective modules were introduced in and are
