can you detail how many watts come out of your panels (efficiency) as well
as what your outgoing A/C available in watts after all the invertors and
losses. Also how do you deal with dead panels after the resin has been
pored. How long have these panels been in service?

If you solder (I like you saying “Solder” not “Sodder” lol ) them + to – to
+ to – I understand that you increase the voltage but what is the wattage
doing ? In the end are you only getting the wattage of one cell?
Thank you lots for your time 😉
Maddy.

I also dont understand how that entire long row is only 4.5 volts????
I have two tiny 2 inch cells that are a combined 4 volts. I can fit it in
my damn pocket!

hi i have a panel it has 30 volts but only produce 2amps in good sun

Stevengrill, Amazon or eBay, search 3×6 (or 6×6) solar “cells” (not
“panels”) mls solar and others offer lots of different packages. Not sure
where Dan gets his but I’ve seen broken cells sold by the pound on Amazon
too.

This is awesome, thank you for sharing this video.. been watching your
tutorials and it helps me big time!

Thanks Dan, I was still half on board with understanding how to correctly
use the bus wire. Once you gave the battery example it make complete
sense.

Very nice thanks I bought some of these and they came with essentially no
information whatsoever so this was perfect to explain solar panel basic
configuration

Could you please tell me where is the video where you make or add the
connections of the main wires
…please

Where do you buy the panel sheets?? You never mention that in any of your
videos. And your website doesn’t offer any content.

WHY in the name of god are you using lead free solder on solar?

am i so glad that i have watched this. I didnt even understand what a
charge controller was, till now. I picked up a system from harbor frieght
without that. Tomarrow i will head to get one. sheesh i hope i havent
ruined my battery now.

What if the cell is broken on the corner? Can you still use it?

My only problem with showing soldering the buss wire so close to the panels
is that people with little or poor soldering skill may get frustrated real
fast. Just to damn easy to over heat the wire going back to the panel and
having them lift off the cell. And if they over heat those pads and they
lift off the cell it is as good as useless to them. Otherwise another
awesome vid

How many of these would you need to power a house? (and how much would it
cost?)

What size tabbing wire and bus wire are you using? Do you recommend a
certain size?

Thank you for this video. You’re providing a great service to the world of
DIY.

Impressive!!! how much did each mono crystalline cell cost? and if you
could provide a link as to where you purchased it? I would like to
replicate this for my engineering project

Agree, its more clear and they do some easy to understand explanation..
more people will be enjoying watching and learning from this video.. and
I’m one of them.. great job..

So you have -/- in each row, +/+ in each row, and then the bus bar connects
positive to negative to positive to negative???? doesnt that short them?

It’s probably a good idea to overkill the bus wire inch/mm2 as you say you
do as cables “eat” more power in low voltage systems as amperage is your
main factor in the power equation to a goal wattage. As ampere meets
resistance in your wire it generates heat by the factor of I2*R=P (I is
Ampere, R is Ohm and P is Watts) So say you are drawing 10amps and your
total wire resistance is 0,8ohm we get 0,8*0,8=0,64 → 0,64*10=6,4watts of
power lost to heat in wires. Go with robust;-)
