I compare current and voltage for 3 different types of solar panels: Monocrystalline, polycrystalline and amorphic.

do a show on the ginea pigs – try to see if they like the shade or the sun.

Of the 3 that I show: The 20W amorphic is the cheapest (100 USD). The poly
and the mono are much more expensive (200 USD and 180 USD, respectively).
As for Dollar/energy, all the panels are probably similarly priced. But the
20W amorphic panel covers a much larger area. If area is not limiting it
might hence pay to use the amorphic type. However, this test kind of
disillusioned my view regarding types of panels. How do prices compare to
where you live?

so which in that 3 panels are more cheaper? I’m using the Poly and I have
great result but investment is not so cheap but I’m saving more now..

Get the guinea pig to run inside a wheel and rig it up to a dynamo. You
wont need solar panels

along the line of my previous estimation: 18 (panels) x 9.125 kWh = 164 kWh
per year. All assuming, that your panels cannot deliver to their max.
capacity as they are not pointed south. Bottom line: try it out! Point a
single panel into the direction as if on the roof and measure the output.
Ampmeters are very cheap!

Hi, Thanks for your reply. I have 255KW on 1 panel and I will have 18 panel
with KWP 4,59 so I will produce aprox. 3600 KW/a. The panel postion will be
on east and west. ReneSola Virtus II JC255M-24/Bb Art.-Nr.: M045 18 Stk.
Hochleistungssolarmodul von ReneSola Polykristallin Leistung: 255 Watt
Leistungstoleranz: 0 ~ +5 W Produktgarantie: 10 Jahre hervorragender
Wirkungsgrad von 15,7% Maße: 1640 x 992 x 40 mm Are these better
information?

if your panel delivers on average 1 % of its max energy, 10 hours per day:
25 Wh per day. times 365 = 9125 Wh or 9.125 kWh, approximately. However, I
doubt that this will be the case in Germany! Mono or poly, none will do the
trick. You will probably need a larger set up.

HI Could please give an advise if I have 250 W Panel and KWP 4.59 I would
like to place the panel on the west and east on the top of a house max
energy required is 4000 KWh per year it is better mono or poly. Many thanks
in advance or your reply Best Regars from Germany

Very cool comparison! Thank you for sharing.

Thanks for the tip, I wasn’t aware of this!

You should also keep in mind the panel rating of each. Most panels on the
market are plus/minus-rated 3 to 5% meaning they may overproduce, but they
may also under produce 3 to 5% (more likely). Its better if you can find a
strictly plus-rated panel where you do not have to worry about under
production.

An interesting hobby too! You’re kind of exploring your own energy
independence. Not many can say that!

One needs many, especially with such incident solar irradiation as I
encounter. Mounting them on a roof, aiming them south and adjusting angle
would help a lot. Also depends on energy footprint. It is more like a hobby
for me that gives me the opportunity to learn more about the technique and
how to use it.

They seem affordable. If they pay for themselves in energy savings, they’d
be a great idea. However, it looks like you’d need a lot of them to power a
home.

I am currently trying to find the best place to set up the amorphic panels
(around 90 USD each). They will improve my heating system (shown in an
earlier video). The 10 Watt monocrystalline panel (40 USD) provides power
to a remote switch and the 20 Watt poly is currently not in use. When I
bought the 20 Watt panel 3 years ago it was around 200 USD. Now it costs
much less, but panels are in general much more expensive in Switzerland
compared to other countries.
MrOtterdude
Neat! Do you have these running anything around the house? How much does an
average panel cost in U.S. dollars?
