Reflections on the Tenth Week of Summer – Tracking the Solar Eclipse
1:45 p.m. |
Fanny
dancing in the Adirondack chair Monday morning, I grabbed a clipboard
and purple pen to draw a chart for tracking the 82% solar eclipse at Wells Wood. My husband Spence glanced up from his computer and
said, “I won’t leave for Cleveland until two-thirty.”
After
forty-nine years of marriage, I could translate his words. He’d
stay through the first part of the eclipse in case my plans for
photographing with a solar lens and recording watts generated by our
solar cells hit a snag. Though he didn’t voice his frequent
admonition, “Expectation is
disappointment,” the
thought reverberated
through my
head.
“Terrific.”
I put the clipboard on the table and dashed downstairs to sweep the
basement before Pablo from Energy Independent Solutions and the
electric inspector arrived at ten. After their inspection, we could
use the power from our solar cells.
Only
Pablo arrived at ten. Young and shorter than me, he had a shadow
goatee, wore a black polo shirt with a company logo, and carried a
computer bag over his shoulder.
“I’m
glad you’re here today.” I shook his hand. “I’m looking
forward to tracking the eclipse on the solar cell monitors.”
Pablo’s
getting-to-know-you smile faded. “I’ll be turning the system off
after the inspection. You won’t get the new electric meter today.
Without the new meter, the electric company would charge you for the
energy you produce.”
“But—”
“It’s
not the end of the world, Janet.” Spence put his hand on my
shoulder. “Everything will be okay. You can still take photos.”
I took a calming breath. “How much electricity would we send back
during the three- hour eclipse?”
Pablo
pulled a folder from his computer case, found our contract, and
studied a page. “Probably fifteen kilowatts. I’m not sure what
you pay for each kilowatt.”
“About
fifteen cents,” Spence said.
I
did the mental math. Two dollars and twenty-five cents–a small
price to pay for tracking the eclipse. “Teach me how to turn the
system on and off.”
While
Pablo waited for the inspector, he taught me how to turn the system
on and off inside the house and out. Then he showed me how to wrap my
knuckles on the Sunny Boy inverter cover to activate the monitors and showed me what a profile of a
system similar to ours would look like on the Sunny Portal website.
At
12:50 I didn’t have to turn the system
on. The inspector still
hadn’t arrived, and Pablo just
finished his tests.
I fastened the
solar filter to
my zoom
lens, set
the pen beside the clipboard, and checked for clouds–only
a few.
My
sister Anita in New Jersey sent
an email.
We
have almost total clouds. Hope you have sun so you can see the
eclipse.
NASA
TV is showing it pretty well.
News
said to take spaghetti strainer outside and look at the ground under
it.
I
wrote back. We've
got some clouds–not overcast. I'm about to go outside and take my
first photo. Starting at 1:00, I'll be taking pictures every fifteen
minutes. Oops. Clouds
just covered the sun.
We'll see. Hustling.
When
I
hit send, Big Ben Chimes rang
on the kitchen clock.
“Yikes!”
I set
the computer down,
grabbed
my camera, and
headed for the deck.
Sleeping
in the sunshine,
our
cat George sprawled
across the
doorway. I stepped over him
and
onto
the deck.
I
squinted into the view finder.
Clouds
streamed across the
sun.
I focused and, when the clouds cleared, clicked a
half
dozen
photos. Hurrying, I stepped back
over
George on the way to the table where I exchanged the camera for the
clipboard. I
hustled down the basement
stairs.
“You
don’t have to hurry,” Spence called after me.
Pablo
was standing by the plant table typing on his computer. He smiled at
me.
I
wrapped my knuckles beside the
Sunny
Boy B monitor, which
recorded watts coming from two of the
five strings of solar cells.
“I’m here for the first reading.”
Pablo
tapped
his knuckles against
Sunny
Boy A which
monitored the
other three
strings.
“I’ll get this one ready for you.”
The
B screen
glowed. Numbers
of
watts
fluctuated rapidly.
Clouds
moving overhead? “Is it normal for the numbers to change so
fast?”
“Yes,”
Pablo said. “You’ll get the average in your reports.”
I
scribbled the largest amount the
monitor flashed.
Pablo
dictated “thirty-nine, sixteen” from
monitor A. “Thanks.”
Back
upstairs, I
exchanged the clipboard for the camera, removed the SD card, and shoved it into
my computer. After
a few mouse clicks, pictures of the sun appeared
behind a
cloud mist.
“Oooooo.”
I squirmed in the chair.
“The solar filter works
great.”
Spence
didn’t look up from his computer screen. “That’s nice, Dear.”
I
saved four of
the pictures, deleted the images from
the SD card, and returned
it to the
camera. Phew. I checked the clock. 1:10. I took a sip of tea, stepped
over George to the deck, and faced in the direction of the sun.
Lifting
the camera, I peered through the lens.
All black. I moved
the camera in circles like swirling a computer mouse in search of a
lost cursor.
Total
black. The sun
had to be up there. I made
larger and larger camera circles
in the darkness. No
glimpse of light.
Sheesh.
I
glanced around the side of the camera for a millisecond
and squinted to see if I was pointing in
the right direction. Looking
through the lens again,
I circled
the camera until
the sun popped into view. In
the area corresponding
to the space between one and two on
a clock face, a black
bite, the size a baby would take from
a medium pizza, diminished the sun.
“Wow.”
Spence
chuckled in the great room.
The
kitchen clock chimed, and I snapped pictures.
Down
in the basement, I recorded watts on my clipboard and told Pablo,
“You ought to come look through my camera. It’s really cool.”
“I’m
just catching up on emails while I wait for the inspector.” He
glanced from me to his computer. “I can do them later. This is a
once in a life time event.” He followed me upstairs, over George,
and outside.
“Look
through here.” I pointed to the viewfinder then
handed the camera to
him.
Pablo
held the camera toward the sun. “Amazing.”
I
called to Spence, “Come
out and see this.”
Spence
walked out, took the camera, and squinted through the lens. “It’s
all black.”
“The
sun’s hard to find,” I said. “Move
the camera around until you catch some
light.”
Spence
moved the camera then moved it some more. “You’re
right. It’s hard to find.” He
handed the camera
to me. “Enjoy. I’ll look at your
pictures.”
Spence
and Pablo went back to their computers. I downloaded photos.
After
the 1:30 recordings, I took our spaghetti strainer out to the deck
and stared at the light streaming through the holes. “Cool.”
I dashed back inside and emailed Anita:
Spaghetti strainer works! The eclipse isn't
that far along, but the holes have the same chunk taken out as the
photos of the sun. EXCITING!
She emailed back: Lucky
you. I used the spaghetti strainer and got nothing. We don't have
enough sun through the clouds to see anything. It's getting even
darker so I think I am relying on your photos and the coverage from
NASA.
At
2:15,
I stepped on the deck. The electric inspector slammed
his car door and walked
toward the house.
I called to Spence. “The inspector’s coming. You take care of
him.”
“I’m
on it,” Spence called back.
I
focused the camera.
The
clock
chimed.
Work
boots thudded on the ramp behind me.
“I’ll
be with you in a minute,” I said clicking a photo. “I’m doing
something important right now.”
“Take
your time,” an unfamiliar voice said.
3:45 p.m. |
I
clicked more
photos and ran
downstairs for the numbers. “The
inspector’s here,” I
told Pablo and dashed back up to
the deck.
Interrupting
Spence and the inspector’s conversation, I said, “Pablo’s on
the way. Would you like to look through my camera at the eclipse?”
The
inspector took the camera, looked up and said, “Oh. Awesome.”
Smiling he handed the camera back. “Awhile ago, I tried to take a
picture of the sun holding my phone over my shoulder, but that didn’t
work.”
Pablo
and the inspector disappeared into the basement.
I
repeated my routine when the clock chimed 2:30. “That was peak,”
I told Spence. “I wonder where the crescent will be when the moon
leaves.”
Spence
shut down his computer and packed his papers. “Be patient.”
Pablo
climbed the stairs. “The inspector left. You passed the inspection.
Spencer needs to sign these forms for the electric company.”
“Do
you want to see the sun now? It’s just past peak.”
Pablo
set his clipboard on the table, took the camera, and peered at the
sky. “Oh, my.” He gave me the camera. “Thanks for letting me
watch. It was nice meeting you.” He gathered his gear and left.
Spence
gathered his gear, said “Be careful,” and headed off to volunteer
in Cleveland.
Anita
emailed again. Did you see the meter come to a halt during the
eclipse?
I
answered. The meter
didn't come to a halt because there was still sun showing. It dipped
way low though. The smaller inverter went from 3166 w at 1:15 to 483
w at 2:30.
At
4:00, I photographed the full sun and rushed
to the basement for recording watts one
last time. I flipped
off the breakers for the AC current then turned the wheels
on the sides
of the inverter boxes
to shut off the DC current. Outside I pulled down
the lever
on the solar disconnect box.
Clunk.
As
tired as if I’d swum a mile, I trudged
inside and called Spence on the phone. “I’m done. I recorded all
thirteen observations and didn’t get bored.”
“Your
enthusiasm was infectious,” he said. “You got the guys
interested.”
“I
didn't infect you.”
He
chuckled. “I’m used to your enthusiasm.”
