RE: Which is more better for your solar installation? Monocrystalline modules or polycrystalline modules
If space is not much of an issue, the advances in technology make the line between polycrystalline and monocrystalline to be very blurred.
I totally agree with you on that.
The last picture, was that the Coca-Cola project you mentioned one time? How many batteries did the huge project gulp? Did you guys use a solar hybrid inverter or incorporated charge controller?
Not Coca Cola but a cocoa processing company in ijebu imushin, ogun state. The entire system is a bit complex to describe at a go. It's comprises of three main sources; an on-grid PV hybrid inverter, a 2000kW backup UPS that makes use of 2056kwh lithium battery at 90V and three power generator of rating of 1348kW, 834kW and 1536kW. The PV inverter works do during the day time but for it to function it requires power to function since its an on-grid system which is where the UPS kicks in while the left over energy supplied by PV inverter is used to charge the battery simultaneously. But at night, the UPS supplies the energy needed and immediately the batteries are drained completely, the generator kicks in till the next sun.
This is some serious power generation! 2056kwh of lithium batteries must have set the owners back about $514k going by rate of $250 per kwh lithium battery pricing. That is something that runs into millions of naira in our local currency! Dang, that is absolutely a monster project.
Didn't know people make use of micro on grid inverters in Nigeria. Do they sell the surplus power generated during peak period to the public electric utility company (our PHCN)?
Don't know about that for now but I can tell you, in a very long time, they make use of micro grid generation without our PHCN.
Yes, it is. A massive 2.35MW Solar project and the company that owns it, is a Dutch and not Nigeria
