Solar Kit - Gridcoin New proyect #2
Hi Everybody !
We have a budget of $1.70 (my personal record) from :
https://steemit.com/gridcoin/@newtechblog/solar-kit-gridcoin-new-proyect
This is not enough to buy nothing BUT enough to continue researching to carry out the project ! Thanks.
In this post I have to choose between solar panels.
First I will explain the steps necessary to assemble a solar panel:
First phase: Silicon
The fundamental step where the Silicon is obtained from the mine and purified.
Second phase: manufacture of (ingots)
The purified silicon is melted in crucibles and the ingots are obtained, which can be cylindrical (if you want to obtain monocrystalline silicon) or square (if you want to obtain polycrystalline silicon).
Third phase: Wafer
They are cut into thin sheets and wafers and wafers are obtained, a substrate on which different chemical processes are carried out until the cells are obtained.
Fourth phase: Solar cell
The solar cell is thinner than an egg shell, so its assembly must be done by very specific machinery that is capable of treating the material as required.
Fifth phase: Solar module
The module is a set of cells assembled and connected to each other.
Then the question is : Monocrystalline or Polycristaline solar panel. (there is a third panel "the amorphous" but according to my research it will tend to degrade faster and its total power will be reduced)
The first difference is seen at first sight. Monocrystalline is a bit black and the Polycristaline is a bit blue.
But the main difference is that monocrystalline yields better in "cloudy and cold" climates and polycrystalline in very sunny climates. This is because the polycrystalline dissipates the high temperatures much better.
Monocrystalline solar panels are usually a bit more expensive.
Forms of connection:
Parallel
The amps are added, the voltage remains the same.
The parallel connection will always be used in solar panels of 12V (36 and 72 cells)
Solar panels of 36 and 72 cells are commonly called insulated plates and only require a conventional solar regulator (PWM)
Serial
The voltage is added and the amps remain the same.
The connection in series is made in solar panels with power between 200W and 260W, composed of 60 cells and for use in solar installations of 24V or 48V.
For this type of solar panels it is necessary to use MPPT maximizing regulators.
At lower intensity, lower cable thickness.
Thank you very much for the support and... to see how far we can go!
Hola a todos !
Tenemos un presupuesto de $ 1.70 (mi propio registro) de:

Esto no es suficiente para comprar nada ¡PERO suficiente para continuar investigando para llevar a cabo el proyecto! Gracias.
En este post, tengo que elegir entre paneles solares.
Primero explicaré los pasos necesarios para ensamblar un panel solar:
Primera fase: Silicio
El paso fundamental donde se obtiene el silicio de la mina y se purifica.
Segunda fase: fabricación de inglot (lingotes)
El silicio purificado se derrite en crisoles y se obtienen los lingotes o lingotes, que pueden ser cilíndricos (si se desea obtener silicio monocristalino) o cuadrados (si se desea obtener silicio policristalino).
Tercera fase: oblea
Se cortan en láminas delgadas y se obtienen obleas y obleas, un sustrato sobre el que se llevan a cabo diferentes procesos químicos hasta que se obtienen las células.
Cuarta fase: célula solar
La célula solar es más delgada que una cáscara de huevo, por lo que su ensamblaje debe realizarse mediante una maquinaria muy específica que sea capaz de tratar el material según sea necesario.
Quinta fase: módulo solar
El módulo es un conjunto de celdas ensambladas y conectadas entre sí.
Entonces la pregunta es: Panel solar monocristalino o policristalino. (Hay un tercer panel "el amorfo" pero según mis investigaciones tenderá a degradarse más rápido y su potencia total se reducirá.)
La primera diferencia se ve a primera vista. Monocristalino es un poco negro y el Polycristaline es un poco azul.
Pero la principal diferencia es que el monocristalino rinde mejor en climas "nublados y fríos" y policristalino en climas muy soleados. Esto es porque el policristalino disipa las altas temperaturas mucho mejor.
Los paneles solares monocristalinos suelen ser un poco más caros.
Formas de conexión:
Paralela
Los amplificadores se agregan, el voltaje permanece igual.
La conexión en paralelo siempre se usará en paneles solares de 12V (36 y 72 celdas)
Los paneles solares de 36 y 72 celdas se denominan comúnmente placas aisladas y solo requieren un regulador solar convencional (PWM)
De serie
El voltaje se agrega y los amperios permanecen iguales.
La conexión en serie se realiza en paneles solares con potencia entre 200W y 260W, compuesta de 60 celdas y para uso en instalaciones solares de 24V o 48V.
Para este tipo de paneles solares, es necesario utilizar reguladores MPPT maximizadores.
A menor intensidad, menor grosor del cable.
Gracias por el apoyo y ... a ver hasta donde podemos llegar !

Thank you very much !
Have you done any research on Amorphous solar cells, a third variant that has advantages over crystalline cells but requires more surface area for similar power output?
Thanks for the info. I will try to search about it. upvoted and Following you. We are now in contact.
