Hi, this is Phil of Peak View Solar and this is Part 2 of "How much solar do I
need?" In the previous video we calculated how many kilowatt hours a year your home
uses. Now, for this one, we're gonna say that we calculated 9700 kilowatt hours
per year, based on that 12 months usage. We're going to take that number, we're
going to start to put that into the software and the next thing we're going to do is we're
going to draw the roof out. And we're going to put it in proper orientation
and proper tilts for each plane of the roof, as you can see in this image. The
yellow is high sun, brown is low sun, so we want to use as
many of the high yellow as possible and avoid the brown. One section is
pointed south and we were only able to get three on it it was a small section
of the roof and the back section of the roof was a remainder or the next level
of yellow that we wanted to tackle to get the most energy from each panel. In
the array you'll notice that there's one panel missing and that's because there's
piping and venting right in that area so we didn't want to we don't want to
remove those, we don't want to cut them off, we don't want to play with them so
we go around those items. Leave the house functioning the way it's
supposed to. So from that layout, which is is an estimate of how much
we're going to produce or how much solar we think we need, we're going to move on
to the simulation page. The simulation page will then come back and tell us
based on everything that's been put in and all a bunch of other variables that
and we can see this one says ten thousand one hundred plus kilowatt hours
per year and it's one hundred and twelve percent offset and that bottom part
you'll see the negative effects of the environment such as soiling and snow that
actually kind of removed from it because they're just
reality around here. So you see 112 percent you're wondering
why is it 112%? In this particular case they are planning on
getting a hot tub and determined that they wanted to shoot for 115%
based on the layout of the roof the efficiency and costs and
then all that. We hit 112% and decided that that was the
best approach and they were happy with that- that we had 112%.
Okay, so, now we got that number, now we want to make sure it's really good.
So the next thing we do is we'll check this out with pvwatts.
And you can google this, pvwatts, and play around with it yourself. It's put out
by the National Renewable Energy Laboratory, which is a sort of a
think-tank kind of thing, up in Boulder, Colorado, where they test panels, they
create new technologies, they do quite a bit. And they have a nice little tour, you
know, you might want to consider it sometime. See it see a lot of what's
going on. But we basically take one plane of the roof at a time so this roof had
two planes so we put in the numbers for the one, putting in the orientation, and
the tilt, and size of of the panels for that area, and then we do that for both.
We add the numbers together and see if they're like if within 1%-2%
of the number that the other piece of software so that we know we're
in line. So we've done that. We know within 1%-2%, so we now know
the size of the system, and where the placement of the panels are gonna be, and
it gives us, Peak View Solar, the opportunity to provide a guarantee of that production.
We've tested it on two different platforms. We see that it's going to
produce this ten thousand one hundred plus and that's a number that will
guarantee for the first year and then there is a small degradation less than
half a percent in any solar panel where we have to adjust but we make those
adjustments and guarantee each that each year after that for the first ten years
that the production would be there. What happens if it's not, well most likely we're
going to come in either add a panel
or pay you whatever the electricity costs you. Anyway,
in regards to that, you'll find that in another section but you now have our
process for determining the size of the system. It's not kind of willy-nilly or
guessed it's very scientific. So I hope that answers that question
and I hope you continue to watch some of our other videos that are going to
address other issues. Thanks a lot, bye.
