In 2013 the california independent system operator published a chart that is now commonplace in conversations about large scale deployment of solar photovoltaic pv power.
Duck problem solar panels.
We ll call this the duck s belly.
Customers with rooftop solar panels buy less energy and pay less to utilities.
The rise of rooftop solar panels has the grid quacking.
That dip creates a few problems for management of the power grid.
In locations where a substantial amount of solar electric capacity has been installed the amount of power that must be generated from sources other than solar or wind displays a rapid increase around sunset and peaks in the mid evening hours producing a graph that resembles the.
Is the solar panel placed in the right location to collect maximum sunlight.
In many energy markets the peak demand occurs after sunset when solar power is no longer available.
You would be amazed at how many solar pond pump problems can be fixed in minutes if you just know where to start to identify the problem.
A flatter sort of duck.
Watch the video to learn the basics about the duck curve.
Http goo gl 0bsajo electricity is incredibly difficult to store so grid op.
The solar panel it s all important connections.
At one level the problem is obvious.
The pump s solar panel should always face the.
But the issue is not limited to giant utility companies earnings potential.
Electricity operators are already struggling to balance consumer demand and intermittent supply.
This duck curve is solar energy s greatest challenge.
No one wants pigeons or crows nesting under their panels so if you notice that they are gathering on your roof your best bet is turning to bird proofing solutions such as mesh wire.
Why is a duck causing problems.
The duck curve named after its resemblance to a duck shows the difference in electricity demand and the amount of available solar energy throughout the day.
If the solar power revolution is to continue it will need to deal with the duck.

The lowest point of demand.
So there s some incentive on their part to exaggerate the duck curve s status as a technical problem.
The demand begins to rise rapidly as the sun sets and people get home at 6 p m.
