Hybrid Solar System generate
power using ,solar power generated from photovoltaic system combine with
another
power generating energy source. These systems generate power in the same way as
a common grid-tie solar system but it use batteries to store energy for later
use. This ability to store energy makes most hybrid systems to operate as a
backup power supply similar to a UPS system.
The term hybrid
referred to two power generation sources such as wind and solar. But here the
term hybrid solar refers to a combination of solar and battery storage which
unlike off-grid systems is connected to the electricity grid.
Why store solar energy
in a battery?
A solar hybrid system
stores excess solar energy and provide back-up power during power off. This is useful
for home owners as well as the majority of businesses which operate during the
daylight hours, a common grid-feed solar system is still the most economical
choice. Hybrid solar systems store solar energy and is able to use the solar
energy at home during the evening even if the cost of electricity is at the
peak rate.
The ability to store
and use solar energy when desired is referred to as self-use or
self-consumption. Solar hybrid system works in the same way as an off-grid
power system but the battery capacity required is less.
Advantages
of Solar Hybrid System
Stores solar or low
cost (off-peak) electricity.
Allows use of solar
energy during peak times.
Power available during
a grid outage or blackout – UPS function.
Enables advanced energy
management.
Enables energy
independence.
Reduces power
consumption from the grid .
Other solar hybrids
include solar-wind systems. The combination of wind and solar PV has the
advantage that the two sources complement each other because the peak operating
times for each system occur at different times of the day and year. The power
generation of such a hybrid system is therefore more constant and fluctuates
less than each of the two component subsystems.
