hello solar fans and welcome to the Sketchup tutorial now we are going to
make a design system and make shadow analysis okay for example if we visit
the site and get the location from the site to enter in the Sketchup so how we
can add the site on the Sketchup go to the file geolocation add location and
just enter your location for example let me enter 31.998017
,35.948388 enter
zoom in and we will get this select region and grab now this is the
house that we want to design a PV system for it okay already you are visiting the
site so you have the dimensions and the high of the building and all the object
components now it's a building okay you can draw on the edges it's like this like
this and like this okay going up 15 meter and offset 0.25 push 1
meter and this is the rooftop okay now there is the stairs room it's in the
center of the building so use the measure
go to the midpoint and it's 6 meter long okay and 3 meter right
and 3 meter left okay just draw lines
delete these dash lines and go up its 2.75 high
okay this is the stairs room now we want to put
12 panels as the 3.6 kilowatt peak system go to the skelion and
change database user database and select the module its AAA ok now select one as
you see the face of the module is to the south not with the building and if we
draw the 12 panels like this for example explode and move it move to right 2 put
control 2 and 2 select all the panels and
make your PV array it's a 12 panels now it's the appearance is so good actually
no because the appearance is better than when the PV array's azimuth angle is
with the home azimuth angle so we can change it by delete this go to the
skelion again select this tilt angle for example 27 as the optimum tilt angle as
we calculated before for the Jordan and the azimuth will be the same of the face
click one panel and continue so this is the panel explode and make your
PV array as you want but note that you have to use a small area as you can and
with good appearance so go right 2 meter again 2 meter and 2 meters
select all the panels and make your PV array as you see this is 8 and 12 PV
array this is better than the 180 azimuth angle to the south
okay you can move it for example like this okay
let we now make the shadow analysis click on the shadow and go to the shadow
in this tray by the way you can add this tray go to the window
default tray a hide tray or show tray ok now go to the shadow in the tray and select 21
December it's the longest shadow in the year in Jordan and go to the 9 a.m.
which is the peak Sun hour 9:00 to 3:00 p.m. okay now check the shadow there is
a shadow in the PV array so you need to change the location of the PV array ok
now to prevent the shadow move it move it up for example 0.5 ok there
is no shadow good now go to the shadow and change the hour 10 11 12 1 2 & 3
there is a little shadow in the corner so move the array for example like this
now there is no shadow on the PV array and we will get the maximum power output
from it as we discussed before in the site survey you need to suggest
allocation for the inverter and in this project we can put the inverter in the
room stairs okay so after side visiting will go to the design stage and we can
add our location and make shadow analysis for the PV array to prevent it
and to get the maximum PV array output as you see this is simple software to
use and easy to laenr and you should practice more and more draw your home
and your friends home and practice see you in that next video and thank you
