Solar panel, AKA solar modules, are not any where near as complicated as everyone tries to make them. You will read all the great things that solar modules are made of and how one uses less of one thing or the other which makes them better. And then another brand uses more of something to make theirs better. This all might matter in the extremes like in outer space but here on Earth they are really all about the same to the home owner. All or 99% of solar modules have a 20 to 25 year warranty and all are so close to the same size per watt that it don’t matter at all.

If you are putting a solar module on a boat or an RV or something portable then you still don’t
care what they are made out of. As long as the frame is build strong enough to handle what
you will be using it for. Modules for your home do not require the extra large frame because
they are normally mounted to a frame that is either, mounted in concrete or fixed to the roof of
your home. Most all data I have read say panels are built to handle over 100 MPH winds.
There are thin film solar panels and even painted on modules. No need for these unless you
are going to be bending them around corners which is not required unless you are building a
solar powered car or air plane. Thin Film is very useful if you are on a camping trip and want
to roll or fold them up for storage. Great for battery charging on laptops, cell phones and IPods.
You can mix your solar panels and brands. As long as all solar panels are rated at the same
voltage and you are wiring in parallel. The amps will add in parallel so the panel amps will not
matter. Only the solar panel voltage has to be the same. The solar modules could have been
split up but there is no need to have two or three charge controllers when one will do the job
with no voltage or amp loss from the solar modules.
If you are wiring the modules in series then the voltage don’t matter. Because the voltage will
add. But all solar modules must have the same amp rating. In series the amps will be the amp
rating of the smallest rated panel so the amps have to be the same.
Just for the looks of it. If you have 2 solar panels of one brand and 2 of another brand you
should mount them apart from each other. But that is only for looks. You will notice that some
homes have one brand or type of solar modules on the top of the house and then 4 or maybe
8 on a pole in the yard of smaller or larger or even other brands. They are all still wired to the
same solar electrical system.

You can mix match the solar panels if you are building amps, long as you keep the voltage
rating the same and wired in parallel.

ratting the same and are wired in series.
Heavy frames on panels are only needed when the panels are going to be mobile, Like on
Boats and RVs. Most have a wind rating of over 100 MPH heavy frames or not.
The warranty is 20 to 25 years on panels and size per watt is very close to the same so it don’t
matter what they are made of. (Chevy, Ford and Dodge all make trucks and they all start and
take you there and back so a truck is a truck right? Just have to get the right size of truck. The
same for modules)
A lot of people don’t know, the hotter the solar panel gets, the lower the voltage and amps they
will put out. The colder the solar panels are the more voltage and amps they will put out.
Solar Panels are the easiest part of the whole solar power system. Pretty much just pick the
ones you like. I like Sharp solar panels because they are Made in the USA with a new factory in
Memphis Tennessee. However, do watch the volts and amps.
Lets try and sum things up a little and make it a little clearer,
