Residential Solar Energy Systems
Grid-tied home solar
power systems are the most common systems used.
For one thing they are not hard to install plus they connect directly
with your current household electric circuit.
They are called Grid-Tied
because these systems tie into the electric utility source (grid) and
circuit you are already using.
As a result, it is easy
to sell your excess energy back to the electric company with this type
of solar energy system, if available. Usually, your are paid in the
form of a credit to your utility bill.
What are the
of a grid-tied residential solar energy systems? (see further details below)
needed for a grid-tied residential solar energy system?
- Ease of installment and use.
|*What is an inverter?
An inverter is a unit that changes the electric current coming from the
solar panel into the same kind of current (AC) that you are currently
using in your home.
- Interconnection agreement
The utility company will review with you how the grid will be connected
and what kind of inspection will take place.
The best time to make an
agreement with the electric company is just when you are starting to
put together your grid-tied solar power system.
This is also an
excellent time to look into rebates, incentives, and credits available
from local, state, or Federal
Energy Tax Credit
Overall, a grid-tied home solar power system is
- less costly,
allows continous power even in bad weather, and
is reliable and flexible.
Main Advantages of Grid-Tied Home Solar Power Systems
1 - Low Upfront Cost -
With a grid-tied system, you don't need to rely totally on your solar
Since most homes do not get optimum sun year round, this type of system
provides your needs when there is good direct sunlight. When needed,
your usual power utility automatically is used.
A system that would provided complete power year round would cost a
whole bunch more upfront, since you need costly batteries for the times
when the weather is contrary. You also would most likely need a
fuel-powered generator as a backup.
2 - Low Cost of Running
and Maintaining a grid-tied home solar power system.
are VERY durable and
provide long-term production once
If you can believe it, there are solar panels made in the mid 50's that
are still producing. Most panels are guaranteed to keep working for
over 20 years.
With a totally independent system, the batteries you would use are much
less economical. They need to be maintained faithfully and still don't
last that long. .
Batteries associated with off-grid systems require regular maintenance
and have a much shorter life than the panels. A generator for backup
power requires maintenance also.
3 - Reliability of
grid-tied home solar systems.
Because these systems are uncomplicated and work in conjunction with
your current power utility, you don't have to run out and
start a generator when weather is bad.
There is much less down time compared to off-grid systems with their
batteries and generators.
4 - Tied-grid residential
solar energy systems provide more flexibility.
Why? First, you have power coming from your home solar power system;
plus, you have power coming from your utility company.
Since you are never without power, you have the time to find out what
your future needs will be and time to add to your current system.
This includes giving you time to set aside money if you do decide to go

of Grid-Tied Home Solar Power Systems
Here's the catch. When there is a blackout, that is, your local
electric company stops working for some reason, your Grid-Tied
residential solar energy system stops working too.
You have no backup electricity.
Why? Well, if your solar power system continued to feed electricity
into the downed wires of the utility company, for example, a worker
could get a nasty surprise. So the connection agreement and setup
requires your system to shut down when the regular lights go off.
Although a Grid-Tied home solar power system offers many advantages and
few disadvantages, you do have other options that could fit your needs
