As you can see, the little ones believe the solar panels to be a place of respite from the sun.  Or perhaps from hawks.  Either way, they hang out under there during the middle of the day.

In vaguely-related news, the New Hampshire's state legislature passed a bill recently (House Bill 1628) so that any grid-tied systems (PV, wind, or micro-hydro) can get $3/watt for their system -- up to $6000, or 50% of the system cost (whichever is less).  That is tres cool, because NH has been seriously lagging on the whole rebate front.

Alright, back to the birds.  The baby ducks have almost a full set of feathers now, though they are still only about 50% of their full-grown size.  Bruce is 85% better (still limping a little), and is again running around like a crazy goose.  The geese are growing noticeably slower than the ducks, and Spruce is only just now starting to get real feathers on her belly (the first place real feathers grow).

I am really sad that the camera focused on the near-grass instead of the far-goose, but I will show you this picture of Bruce anyway.  If you have met Bruce, you know that this is picture captures alot about his personality.  Namely, "GRASS.  GRASS FOR ME."

According to this nifty little press release, Fat Spaniel and EnerWorks have just partnered to bring great solar-monitoring software to the world of industrial solar hot water.    Fat Spaniel is a cool company -- they make software that you can hook up to your solar installation and check on your energy production on the web.  It keeps historical data and lets you do real-time monitoring of systems that are far away.

You wouldn't think that was particularly unique -- using computers to monitor your renewable energy setup -- but it really is.  We have a little auxiliary piece of equipment (the OutBack Mate) that lets us see what our system is doing, and it's connected to our charge controller via a very long ethernet cable.  Ours is strung up to the office, so we can check our battery levels and power generation from our desks.  It even has a serial port (so 1994!) so that we can plug it into our computers, but we haven't bothered (yet).

Enerworks (the other company in the above press release) focuses on solar-hot-water systems for commercial applications -- hotels, hospitals, etc.  That is totally spiffy, because solar-hot-water systems tend to pay for themselves pretty quickly and are a lot easier to understand (sun!  it makes things hot!) than photovoltaic systems.

In other news!  Xantrex also released a solar-system monitor this week!  And it's Wi-Fi!  It's pretty odd to me that the manufacturers of solar products are so slow to realize that all of their customers are geeks -- we want to know how many kilowatt-hours we produced!  We want to see our current amperage!  We want to see them both in colorful charts and graphs!

Not that we have any amperage here.  We are in the midst of yet another snowstorm.  It is the first day of spring!  As the Yarn Harlot says, "There can only be so much more snow before the rotation of the earth on it's axis makes it impossible. Hang tough."

Tate pointed us to this article in the San Jose Mercury News and asked what we thought of it.  Well, here's what I think of it: man o man, people are so dumb.

Here's the story:

1. Between 1997 and 1999, a couple in Sunnyvale planted a bunch of redwood trees in their backyard.  Looking at the overhead photo, it is pretty clear that they did this so that their neighbors did not have a direct view into their living room.
2. In 2001, one of those neighbors installed 10kW worth of solar panels on his house. 
3. Now the trees are tall, and they shade a bunch of his solar panels.
4. He invoked the little-known California Solar Shade Control Act, which is now levying stiff fines on the tree-owners for not cutting down trees that shade solar panels.
5. The court found against the tree-owners, but they are appealing the ruling.

This is dumb on so many levels.  

• Did solar-panel-guy think that trees weren't going to grow?  If there are trees almost shading your site, then within a few years they will shade your site.  By definition, that makes it a bad site for solar panels. 
• For the amount of money that 10kW of solar panels cost, you'd think he could buy some common sense. 
• The law says that trees that were there before the panels were installed are OK, except that it also says that if they grow to cover solar panels, then they're subject to removal/fines.  So... trees are ok, as long as they don't grow?  The law really should have some sort of "reasonable growth" clause.

Personally, I'm totally with the tree-owners on this one.  Mr. Solar Panel was dumb to put his panels under baby redwood trees, and I'm pretty sure it's not fair to fine your neighbors for your stubbornness.
