Task specific photovoltaic modules

All photovoltaic modules are classed as some form of TSPM (Task Specific Photovoltaic Module). This means that every solar panel is designed to perform a particular task. 

Conventional solar panels are called BSPMs (Battery Specific Photovoltaic Modules). Most panels sold commercially are of this type and are designed solely to charge battery systems. These panels come in 12 volt, 24 volt and 48 volt configurations. Most have short circuit current ratings of from 2 to 10 amperes. 

ESPMs (Electrolyzer Specific Photovoltaic Modules) are uniquely designed to match the power requirements of electrolyzer systems. This makes them more energy efficient and economical for their intended use. 

Whereas BSPMs output higher voltages and lower currents, ESPMs output higher current and lower voltages. 

Although not always possible, the best engineering practice is to design any power supply to match the specific appliance that will use that power, so that as little energy as possible is wasted. Still, BSPMs can be used efficiently for hydrogen production if they are used to power a bank of electrolyzers rather than just one.
