Off grid electrical power systems can be single-source using solar, wind, hydro, or generators, or hybrid combining sources. Hybrid systems supply AC or DC power using conversion devices. Generated electricity is stored in batteries to provide power at night or without sun/wind. Rural electrification brings power to remote areas, allowing mechanization to increase farming productivity and reducing costs. It allows activities after dark like education, and improves safety, healthcare, and reduces isolation with telecoms.

1. Off Grid Electrical Power Systems
.

2.  Off grid, electricity can be generated by single-source system
using solar photovoltaic panel, wind turbine generators, micro-
hydro power plant or fuel-powered combustion engine generator
sets, or by integrating, one or more types of these electricity-
generating sources in a so-called hybrid system,
 Hybrid system can supply power to AC or DC load or both. It
may require AC, DC or both types of buses power conversion
devices are used to transform power.
 An off grid power system will need somewhere to store the
generated electricity and this is usually stored in batteries.

3.  The battery bank provides electricity at night, and during
periods of cloud cover

5. Rural electrification
 Rural electrification is the process of bringing electrical
power to rural and remote areas.
 Electricity is used not only for lighting and household
purposes, but it also allows for mechanization of many
farming operations, such as threshing, milking, and hoisting
grain for storage.
 In areas facing labor shortages, this allows for greater
productivity at reduced cost

6. Social and economic benefits
 Allow activities to occur after daylight hours, including
education. In impoverished and undeveloped areas, small
amounts of electricity can free large amounts of human time
and labor.
 In the poorest areas, people carry water and fuel by hand, their
food storage may be limited, and their activity is limited to
daylight hours.
 Reduce isolation through telecoms
 Improve safety with the implementation of street lighting, lit
road signs.

7. Social and economic benefits
 Improve healthcare by electrifying remote rural clinics.
 Reduces the need for candles and kerosene lamps with their
inherent fire safety risks and improves indoor air quality.
 Improve productivity, through the use of electricity for
irrigation, crop processing, and other activities.
