Subjecting used solar panels to rigorous integrity tests

mctfopt:
What does this integrity test entail? If you don't mind, can you get into more of the details of this testing? Thanks.

feflo:
It simply means a test to ascertain if the panels can still deliver the rated amps or something close to it. Remember they are used panels, I need to ensure the condition is good before use..
It involves hooking them up to a battery and checking to see how much Amp it could deliver to the battery. The battery is hooked up to a load so it doesn't get to float quickly

Many thanks

mctfopt:
Ok, that is a good way of testing. Keep up the good job.

bros please help me explain this, lithium battery 3.7v 8ah cells for sale @ N3, 600/cell...

feflo:
Any battery that's not up to 12v is called a cell. 2v, 6v batteries are called cells. What it basically means is that you need a combination of cells to make a battery. In this case, you have 3.7v 8ah cell, it means you will need 4pcs, to get a usable 12v system. 4pcs gives 14.8v 8ah, 8pcs gives 14.8v 16ah and so on. You could vary it to get your desired voltage and amphour.
Thanks

Abigai:
thanks bros but using this how many pieces will give me a 24v 100ah bank and how long will it do on 200watt load. thanks

Sealed Lead Acid Batteries

Sealed lead acid batteries are also known as valve regulated lead acid (VRLA) batteries, recombinant batteries and often called maintenance-free lead-acid batteries. Examples of VRLA batteries are:
• Absorbed glass mat (or AGM)
• Gel cells

The term “seal lead acid battery” is misleading: a sealed battery would be a safety hazard due to overpressure risks the battery is overcharged. There is always a safety valve present, hence the name valve-regulated. Even the term “valve regulated” does not really describe this technology. These are really “recombinant” batteries. This means that oxygen evolved at the positive will mostly recombine with the hydrogen ready to evolve on the negative and thus prevent water loss. The valve is only a safety feature in case dangerous amounts of hydrogen are produced.

Flooded Lead Acid Batteries

Flooded lead acid batteries, or wet cells, are the oldest type of rechargeable battery still in use. This type of battery contains a liquid in an unsealed container. This means that the battery must be kept upright and in a well-ventilated area to ensure safe dispersal of the hydrogen gas produced by these batteries during overcharging. The lead-acid battery is also very heavy for the amount of electrical energy it can supply.
Flooded lead acid batteries require period monitoring and topping up with distilled water. Despite these disadvantages, flooded batteries have high surge current, easier to troubleshoot and are relatively inexpensive.

Gel Batteries

A gel battery (also known as a “gel cell”) is a sealed valve regulated lead-acid deep cycle battery and has a gel electrolyte. Unlike flooded lead-acid (wet cell) batteries, these batteries do not need to be kept upright. Gel cells virtually eliminate evaporation of the electrolyte, spillage (and subsequent corrosion issues) common to the flooded lead acid battery, and boast greater resistance to extreme temperatures, shock, and vibration. As a result, they are often used in automobiles, boats, aircraft, and other motorized vehicles.

flooded are car batteries right?

feflo:
Car batteries could be flooded or SMF or SLA.
Thanks
