What if you skipped the high purity and went straight to creating a crystalline structure? Would it still be able to perform the same uses, just at lower efficiency?
MPPT is not unique to PV cells/arrays, it applies equally to hydro generation and wind generation although, in the latter case, the response time may need to be shorter/quicker.
Great video to explain MPPT methods. As you noted there are other methods ---9yrs later it would be interesting to hear what some of the other techniques or methods are ----> Please do a follow-up video. Also it would help if you could clarify why and by how much Imp > Isc.
Very helpful thank you. Im looking for a simpler solution. Say a potentiometer thats lets you set the voltage while watching power either go up or down. You being the tracker. Gets rid of all that overhead and complexitity and coud be worth in some cases where you dont need constant and percise tracking. I have a similar situation with solar tracking as the day goes along. I only need 3 positions, not constant perfect tracking so Im hopig to get an understanding of mppt charge controllers to achieve something like this. Seems like all you'd need is just away to limit the voltage/current, but also not waste it as heat and you should be good for setting up maximum juice for your system. An automated circuit would be ideal, but for educations sake i think a simpler circuit showing the essence of the mppt idea by doing it manualy would be helpful.
There is a new method for making monocrystalline solar cell material that doesn't involve cylindrical ingots or ribbons. It's explained here in this (very short) tutorial: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-EZQtJU0Ib9Q.html Thanks to this process, it is no longer possible to tell monocrystalline solar panels by the little white diamond shapes at the cell interstices. Those diamonds were the backsheet showing through the cell corners, which were the original cylinder edges. For that reason and for the emergence of the PERC process, which improves efficiency in mono-si cells but not so much in poly-si cells, poly-si is pretty much over as of 2023.
can we connect two mppt solar charger controllers to the same solar array ? This is because i have one mppt that works on grid when i have the grid power and then I have another mppt which charges my battery with solar array when there is no grid .
It's not unique to PV. Any energy source has a trade off situation that results in an optimum compromise that varies depending on source and load conditions. Consider bicycle gears... These are selected to optimise the trade off between torque and revs so that the cyclist can produce the most power in the specific riding conditions and his dynamic strength.
The slope of I-V curve at Voc is far from Rseries of cell. That slope is a parallel combination of diode conduction and actual Rs of PV cell. Slope of Isc closer matches Rshunt when defects dominate Rshunt. Both silicon bulk Rseries and bulk silicon Rshunt are affected by illumination level on cell. These resistances increase at low illumination. For shunt this is good at low illumination levels but cell is often dominated by defect shunts. For series resistance this is bad as series resistance increases at low illumination level and dominates over the metal current collection series resistance.
