My Newest Solar Milestone: $1000

I just got my latest net metering statement from PG&E and I’m happy to see that I’ve just crossed the $1000 mark as of July 6th — as in PG&E now owes me over $1000 for the excess electricity my system has generated over the six months so far (January through June).  Woot!

That’s after all my household consumption, including charging my electric car (Nissan LEAF), running my well pump and water treatment system, etc.  What it doesn’t yet include though is heating the house since my heat pump was installed after the cold months had past.  So I don’t yet know how much heating my home will dig into my solar production surplus come fall and winter.  (I also don’t have a regular daily commute right now so I don’t have as much of a need to recharge my car right now.)

Update (8/15): Looks like my excess production for July added another $400 to that total.  More woot!

However, the fine print here is that this number is just used to compute the net “true-up” amount for the whole year at retail energy prices.  If I end up with excess production for the year, PG&E will only be paying me at the much lower wholesale rate… yeah, not quite so much woot. ;-)

Another cool thing to see though is how well these SunPower panels perform in overcast conditions.  It’s still overcast just before noon today in Santa Cruz and yet they’re pumping out 2760W right now.  (Compared to 7000W on a sunny day at noon, or a peak of 7900W about 2 pm, even with dirty panels.)  Sweet!

Slippery Slope

I half-woke this morning to the noise of a crash.  Or perhaps I dreamt it?  I listened for more but there was nothing.  Had I heard anything?  Pan was in the room.  Hera wasn’t.  Maybe knocked something over.  Perhaps I’ll find out later?  Back to snooze.

Much later, and after browsing the web and answering some email, I finally get up and make my way downstairs with Pan running ahead of me expectantly.  First thing he wants everyday is to go outside.  I go to open the porch door and… a very perturbed Hera comes rushing up to the door from outside and gives me an earful.

And I’m thinking… what the heck??  How did you get out?  How long have you… hey… I don’t suppose that noise…

And then I have a hunch.  So I go upstairs and take a look at my solar panels and sure enough, there’s the evidence. Kinda funny to see, actually:

You see, I have a pet door in an upstairs window that let’s Pan and Hera get out to a patio off of my bedroom.  And I’ve got several planters out there with grasses, herbs, catnip and nepeta — all kitty goodies.  They do have to brave the various hawks and birds of prey, but they’re pretty good size cats and it seems worth the risk to let them enjoy free access.

So it would seem that Hera decided to try walking on one of the panels this morning and slipped or perhaps was even startled by the shadow of a hawk overhead.  (In fact, one such shadow passed over while I was up there to take a picture.)  She then must have scrambled to hang on, crashed into the metal gutter (the noise I heard) and yet still tumbled off the side and down to the ground.  A pretty good fall for a big fifteen pound cat particularly since the ground is much lower on that side of the house.  Well, Hera was a little annoyed for not being able to get back in the house all morning but no apparent injuries.

Next day thoughts: It is odd how there are simple paw prints at the top of the panel, scrambling smears at the bottom and nothing in between.  Did something try to pick her up?  Maybe, but she didn’t have any qualms about going out again later that night and she doesn’t seem to have any wounds from talons.  A mystery remains.

Driving a Tesla Model S

I went to the Tesla Model S test drive event today in Fremont.  As a Model S reservation holder, I was able to go to the factory tour last November (here’s my pictures and video from that) but this weekend, with the delivery of the first vehicles to customers, this was the first of several drive events being held around the country this summer.

The test drive route was a nice mix of private and public roads and highways over about eight minutes.  There’s lots of pictures, videos and commentary available on the web already from this weekend but I thought I would add my feedback comparing it to driving my Nissan LEAF (and the Audi A3 3.2 that I used to own).

My first impression on pressing the accelerator and turning the wheel was “damn, this thing feels like a tank.”  It’s a beautiful, very fast tank, but oh does it feel big and heavy.  As a passenger at the ride-along last November, it wasn’t noticeable — because it is so quick and handles very well (even through the slalom course).  But when you’re behind the wheel and coming from the likes of smaller cars, you definitely notice the weight and the size.  I was disappointed by this.  I know it looks big but I had hoped to not be able to really feel it when behind the wheel.

Given that the Model S has a much more powerful electric motor than the LEAF, I think part of what I was feeling was how they’ve calibrated the accelerator.  (Or perhaps it’s really just the significant amount of mass you’re having to throw around!)  I suppose the LEAF’s accelerator is actually a bit touchy.  It leaps forward with just a slight press.  But then this contributes to the fun and lively feel of driving the LEAF around town.  And this despite it’s actually rather poor 0-60 time.  Of course, with full torque immediately available and no gears to shift, it is actually very quick at typical city speeds of 0-30/40 mph.  And its small size helps it feel more nimble than something like the Model S.  Of course the Model S is flat out faster (must faster than most cars and certainly most sedans) and it actually handles that speed and its weight far better than the LEAF.  Unlike the LEAF, it’s definitely engineered for performance.

But the Model S is still a big, “executive-styled”, “BMW 7-class series” kind of vehicle and isn’t really my kind of vehicle.  So I still have a lot of doubt about following through with a purchase.  Yes, it is expensive, as Tesla’s business plan is built around the notion of starting on the luxury end and working to bring down costs to develop a more affordable mid-priced electric vehicle.  While the expense is understandable – we’re still on the leading early-adopter edge for all electric vehicles, much like cellphones and plasma TVs when they were first brought to market – for this kind of money, I need to really love the vehicle as it is.  I’m not canceling my reservation just yet as I’ll probably have until the fall before I have to commit, but what I really want is a smaller, sporty, all wheel drive hatchback – all electric, of course!  Maybe I’ll have to wait for the third generation Tesla, the supposed Model E.  Or maybe somebody else will step up to the plate?

Aliens!! Hiding in the Sun!

I found the alien spacecraft hiding in front of the sun today!!  It’s still there now as of 5 pm June 5th, slowly moving across the face.  Alert the media!

Strangely, neither Pan or Hera seemed particularly concerned about this news, but at least Hera seemed to be paying attention.

 

(Okay, yes, for the benefit of finding this later, it’s a transit of Venus.)

Eclipse Watch

I drove up to a spot near Lake Tahoe for the annular eclipse on the evening of May 20th, 2012.  Unfortunately, I didn’t plan ahead and get the necessary solar filters to do any photography work — and checking around the couple of days before the event proved fruitless.  But at least I had binoculars so I could set up a projection to watch it.

My little arrangement makes me think of the robot from the movie Short Circuit.  Hmm, I suppose Wall-E too.

Home Theater Rebuild with the JVC DLA-RS55

It’s that time again: upgrade time! I’ve moved to a new home in Santa Cruz and I now have the wall space to do a super widescreen (2.4 by 1) in a Constant Image Height (CIH) setup and do it big: 12 feet wide by 5 feet tall!  Sweet!  And I’ll give 3D a try too with the JVC DLA-RS55.  (My last “home theater rebuild” was going high definition back in 2007 in the loft of my condo in San Jose.)

So here’s a photo journal of the building out of my home theater in my new home in Santa Cruz, starting with the the “before” and “after” shots:

The house is laid out with a kitchen and a large living room area on one end and a second living room area at the other end and a dining area and entry way in-between….
