Translations:PV system types/11/en

A common system in less developed off-grid areas, most systems below 100W of PV are of this type. An economical option to provide lighting and energy for small appliances. Using only direct current has the advantage avoiding energy losses due inefficiencies created by an inverter (inverters are typically only around 80%-90% efficient in practice) and the energy that is required to power an inverter when it is standing by. The disadvantage of not having an inverter is that most appliances are designed for use with alternating current, therefore the available DC appliance market is often much smaller.
