At most 2 tv and home theatre, 3 fans and 10 energy saving bulbs.

ichakaobos:
1500w or something that can carry a 3bedroom flat.

MONO-CRYSTALLINE OR POLY-CRYSTALLINE SOLAR PANELS: WHICH IS BETTER?

My View

What is the better type of solar panels for my home, mono-crystalline or poly-crystalline?

There is often great debate over whether you are better off with poly-crystalline cells in your solar panels or mono-crystalline solar cells in your solar panels.

I think this question is one of the last things I would concern myself with if I were buying solar electricity panels and here is the reason why.

When two solar panels are marketed at a particular wattage (say 200 watts) it means that (at standard test conditions) both will produce at least 200 watts, provided both of these panels have no negative power tolerance in their specifications.

This is the case even though one of these panels may use poly-crystalline cells and one of these panels may use mono-crystalline cells.

What is important to remember is that any slight differences in cell efficiency between poly-crystalline or mono-crystalline panels is already taken into account when they are rated and so is of little or no relevance to you as the end consumer.

It may be that the mono crystalline panel in the example above is fractionally smaller than the poly crystalline panel that produces the same amount of power, because perhaps the mono crystalline cells used may be slightly more efficient but in the end both are going to produce the same amount of power.

A better cell efficiency simply means that the mono crystalline panel might be fractionally smaller but if you look at the sizes of commercially available poly-crystalline panels and mono-crystalline panels of the same wattage (say 200 watts) they are very close to each other in size.

Both types of solar cells usually have a similar temperature coefficient and so in practicality both are likely to produce an almost identical amount of power over time.

Similarly, there is no evidence that either poly-crystalline solar panels or mono-crystalline solar panels decay at a different rate over time.

This is why I would not be too concerned about whether the solar installer I talked too offered me mono-crystalline or poly-crystalline solar panels. In other words, what the poly-crystalline solar panels lacks in cell efficiency, they gain in size. If you have enough roof space, you need not concern yourself with the type of panel you are given either poly or mono.

turok:
Like you suggested.
I got the meter
Tested the ba3
One read 13.95
Why the other read 8.32. (I guess this is the faulty one)

turok:
@Feflo..... Please I noticed my inverter will show it is load immediately I put it on without putting on anything. What will possibly be the problem? My ba3 na run down quickly.

Opengates:
How soon sir? Cos I dont want to spend the money on something else

Opengates:
Will like to know when next you have 100AH. Thanks

Feshizzy:
Good Day Sir,
What's the life expentancy of these batteries like the estimated cycles remaining?
Thank you for your response in advance!

Opengates:
OK. What ah can the money get me at present?

And what is the price for 100ah?

Opengates:
@Feflo, you are doing a great job. Weldone sir.
Please can I get between 100ah and 200ah battery in good condition with the budget of 30k?

Please reply as soon as possible. Thanks
