Completely thorough and exceptionally communicated to the laymen.
Brilliant. I am learning and studying all the knowledge you are sharing
with all of us including careful research and planning prior to investing
into a home solar system to maximize my ROI. Thank you.

Just want to say how much I appreciate your video Martin, you’re helping a
lot as I try to get my head around this

Concerning your calculation to cater for losses:
By saying that you have 40% losses, you’re effectively saying that 60% of
electrical potential is usable. To my understanding, this would mean that
your equation should be 8,200W=(0.6)*(amt of power actually needed).
Calculating this way, you would need 13,667W of power.
Intuitively, your calculation of 11,480 seems incorrect to me because 60%
retention of 11,480 Watts of power would result in production of only 6,888
Watts of power.
Could someone please explain if I’m misunderstanding the concept.

Thank you for the tutorial. Very instructive and I cannot wait to build my
own.

Hi MJ, I don’t know if anyone has pointed this out previously, but you
can’t add percentages together to come up with the total power loss. You
have to consider the power loss over each item. For example, a 40% loss on
100 units leaves 60 units. A further 25% loss (on 60units) leaves 45 units.
However, you added the percentages together which would have given the
result as 65% loss leaving only 35 units. So the overall losses are not
quite as bad as you calculated. Hope this helps.

Why pay a huge amount like $1000’s for utilization of solar or wind power
when you can have the opportunity to build your own home made solar system
for less than $200.

Hi MJ. Excellent vid. I’m planning a modest home in Elgin in the Cape and
need to design my home as energy efficient as possible. Part of this
process is deciding on a PV system setup and I believe integrating a heat
pump for geyser. I’ll study the rest of your vids … mind if I call on you
for fine-tuning?

Really nice videos and I really appreciate your hard work put in here, but
I see a mathematical flaw in this video. When you add up percentage losses
you just sum it up like 2%+10%+5%+3%+7%+30%=57%, but that is wrong, because
if let’s say you have 100W of energy – 2% power tolerance = 98W, then 98W
gets 10% heat loss = 88,2, then 88,2 – 5% because of dirt = 83,79, then
those 83,79W go through wires and loses 3% more and go down to 81,28 then –
7% = 75,6W – 30% (batteries) = 52,9W left (100 – 52,9 = 47,1W and 47,1%
lost from 100), so instead of sum of 57% this should be around 47,1%. You
just can not sum up %, because your next loss will always lose some part
only from that amount which is left from previous losses not from full
primary amount. It can look like a little mistake, but sometimes numbers
can differ radically if you just sum up percentages, just imagine if you
have four losses of 25% each in a row, then by adding up you get 0 energy
left, but in reality there is still 31,64% of starting energy left after it
goes through all those four losses of 25% in a row.

Thanks for a very informative video. Can you recommend an installer in
Johannesburg?

All info is educational but I’m a licensed master electrican through out
California and have been installing solar for about 15 years now i have
done commercial and residential solar jobs and have assisted in that solar
project as a solar consultant for the Mojave desert solar project plant
,that supply’s power for the city of Riverside Ca . but when all is said
and done you will loose what you loose but for the most part if you size it
correctly and add deep cycle batteries for a home all will be A OK at most
you will have more worries when a solar panel breaks and having to wait a
week for another one to get ordered in.

How are solar panels produced ? I hear that it is a toxic process that
involves dangerous chemicals being combined and exposed to high levels of
electricity. The exposure to electricity “boils” off and a usable
photo-cell is created. Since the cost of solar panels does not seem to
correspond to economics rules i.e lower cost for solar power I believe this
process to be true. Example the cost of high definition T.V. When high
definition T.V. were first introduced the cost for then was extrema and has
more sold there price reduced, why is this not the same for solar
electricity…..could it be because ” it is a toxic process that involves
dangerous chemicals being combined and exposed to high levels of
electricity.” Please educate me on the process.

Would it be a bad idea to just use all the power you get from solar power
and put them into the grid entirely to get a larger credit and not have to
worry about powering your house in such a proper way?

excellent info!!!…….ive fabbed 3 tracking solar arrays for the back
yard and your numbers will definatly help in the tweaking of the
system….what the heck..its a hobby…Lol

Have you though about fabricating a mount for a car window washer and wiper
on your solar panel? when they starting to get dirty just flick the switch
and let the wiper clean it, i think this would come in very handy if your
panel is mounted high up and hard to reach. Just a though.

I have a 250W solar panel and 150ah 12v battery, and I want to know what I
need to use,a 20A charge controller or 10A charge controller? ,and what
wattages of inverter I need to run a TV or an electric fan?

My critique, trying to help. Maybe purely on a sales type, than arguing.
From a base point, depicting energy production from a max, descending to
various “losses”, sounds technical, but it’s (sorry) you habitual way of
deducing life decisions. That’s only to say, it’s personal to you, not
universal. That “cup half full” thing, basically. That is to say, without
solar you are at ZERO. Therefore, 0 is the starting point, & ALL energy
production exist in positive terms. The only “loss” of energy, is drawing
from the grid. 1,000 watts isn’t a 30% loss, it’s a 1,000% increase from
non solar. If the conditions only produce that much, it’s not a loss;
unless you convince yourself it is. Compare it to drawing from the grid,
that might help. I like this though. We, humanity, needs this; people like
you. Thanks.

mjlorton
Thankyou so much for posting this video as it helped me learn and decide
how to put together my own portable solar generator. I have included a link
to my first ever public video of the unit, I hope you think I did ok for my
first time. Also thankyou for your amazing review of the CTC CM100 Clamp
meter as I ended up buying one of these via your amazon shop and I really
could not have made this with out it , so again mjlorton Thankyou so very
much for many of your videos. here is that link :

PS please never splash water on a solar panels it could crack if the panels
are hot and the water is too cold. And never modify windshield wipers on
solar arrays wipers are for cars only
