Because polycrystalline is less efficient

for the same output the panel is slightly larger

otherwise there's no difference monocrystalline polycrystalline

just efficiency and size

I bought this MPPT charging controller about $85 during Prime day
https://www.amazon.com/gp/product/B07DNVTJHD

The 20Amp version cost less and was about $62 in July and $69 in Aug. So possible onsale again around Black Friday.

You can buy a option Bluetooth module so that you can look at the solar panels and battery status.

I did not buy the Bluetooth module but am able to read the numbers via Raspberry Pi with a Python script and a USB serial cable from the charging controller (It seems like the newer one does not come with cable anymore)

Supposedly, Mono was to be superior due higher quality silicon used, and Poly was supposed to be superior due to shading efficiency versus mono. This vid pretty much convinced me Poly is what I'd prefer: https://www.youtube.com/watch?v=dZ_jrSAk-DU

Then a brand comparison of the Poly's: https://www.youtube.com/watch?v=k8hYSGI5hiU

Even in these vids. this Renogy was 120-30 dollars, not too long ago.

edit: yeah, WIll says silicon when talking about silicone...but since it's silicone on a silicon panel, it's forgivable. lol

I realize there's labor and inverter overhead, but its nuts that exrapolated per KW, this would price out to like $9K for a 9KW setup, but if you wanted a 9KW setup turnkey installed at your house it would run you about $30K.

Why should I invest in the environment when middlemen are eating up all the benefits/profits. This is where the gov needs to step in, its impossible for regular homeowner to regular standards with utilities and navigate zoning codes. They need to offer a turnkey service like other gov mandated utility delivery schemes.

Any pulse width modulation solar controller with LCD for about $8- 12 dollars on eBay for 20 amp unit

works with two or three different types of battery
adjustable parameters
PWM supposed to be better for the batteries over MPPT
and you need to have a big system to see the advantages of MPPT

If the battery is big enough and you're using just this panel you don't need a controller yet

The main advantage of monocrystalline is if you have a limited amount of space you can fit more wattage in that same amount of space with monocrystalline
at a higher price

like on a single rooftop

The main advantage of Poly crystalline is lower price

However if your main concern is price upfront cost you can build your own panels from whatever quality cells you want to use off eBay

you can even get factory rejects almost free
