Hi Jeff,
1500Wh? That's a 62 watt loss 24/7. That is surprising as it's more than twice
what the manufacturer claims; 25 watt with no load or 0.6kWh daily. However,
as loads come on the idle losses quickly diminish as they are overtaken by the
load. I have not done any SI jobs but that number,
William,
I did a 2 year long study on a Sunny Island 5048 grid-intertie battery back-up
system and found the SI and batteries used about 1.5kWh per day in "overhead".
The batteries were 8 Concorde AGMs 212Ah C20. Hope that helps.

We've got an array of Silicon Energy modules "out back," and in the
interests of scientific discovery and procrastinating from what I really am
supposed to be doing, Kelly, Seth and I just ran a few experiments to see
if we can quantify the amount of irradiation that makes it through the
array.

Hi Keith,
You may be able to accomplish what you are seeking with the Lumos' LSX
series frameless modules with the clear backing:

They let through quite a bit of light.
Best,

Hi William,
You asked how much energy the "battery" is expect to consume. At 300 to 1200
watts perhaps you mean how much the XW's consume from the battery? The idle
current? Please clarify. The battery does not consume power except for self
discharge which is very small. If healthy, the 8A8D wi
Folks,

How well does it work to store dry lead acid batteries for the long haul,
let's say 10 years?
Would it be worth purging the batteries with nitrogen? Does the acid store
that long or would you need fresh acid in ten year to commision the dry
cells?

Appreciate the feedback. One of the questions that I'm seeking to determine-
how much light will filter through the spaces between the cells to the surface
below?
Lets say for someone that wants to grow orchids- they need low light, as an
example.
Wondering how much light is diffused thr
