Is an Off-Grid, Grid-Tied or Hybrid Solar System Better for Your Home?
Electricity from solar
systems has never been more cost-effective. This is why it’s an appealing
alternative for many homeowners. When you are thinking about installing solar
power to your home, it’s easy to get caught up in the details.
Here are the three primary
kinds of home solar arrangements:
They all have their
advantages and disadvantages, so we’re going to give you all the information
you need to make an informed decision.
A solar system that’s
grid-tied relies on your local electrical grid. The DC power produced with the
photovoltaic (PV) paneling gets transferred through a grid-tied inverter that
transforms it into AC electricity. This kind of power is compatible with the
If you’re buying or leasing
a grid-tie arrangement, you’ll sign a net metering agreement with the utility
firm. The terms are usually dependent on your state, but typically set the
price of the power meter and the power transferred to the grid.
Off-grid arrangements have
the ability to run independently from the grid. Additional hardware is needed
to attain this standard. DC electricity produced by the PV panels gets
transferred into a charge controller. This measures and controls the charge
rather than the utility company’s grid.
It gets fed to a DC battery
bank after that where it is placed into storage. The charge controller will
figure out if it needs to full-load charge, trickle charge or stop the current
from overloading the bank.
Your house links up to the
battery bank with a power inverter. This inverter transforms the DC electricity
from your batteries into the 120V AC electricity used by the majority of
Even though lead-acid car
batteries could be utilized to make a battery bank, this isn’t advised. These
batteries lifespans are very expedited, particularly if they’re used each day.
Such batteries squander roughly 20% of the energy stored. This waste precious
power and undermines the “green” aspect of your solar system.
If you want the best of both
of these options, you could choose a hybrid solar arrangement. When you use a
hybrid setup, the solar battery gets utilized as a reserve if the grid were to
Because it is being utilized
as a reserve rather than a full-time connection, the battery releases energy
infrequently. This increases its life. The battery you won’t be replaced as
frequently as the other choices and you won’t have to buy a backup generator.
Remember that battery banks don’t get charged when the power goes out. Solar panels
that are tied to the grid are meant to and their power production in the event
that the power goes out.
