happy new year my good friends on this thread..

I discovered a significant drop in output of my system so I climbed up to see what's happening.
the problem was dust . all I did was to use a big hand size foam and clean. although not easy but I stretched as far as my arm could reach.
the result was a significant improvement .
I hereby recommend u observe ur panels for dust.
If u reside very close to an untarred road...am sure Ure already a victim.

hi,

same problem here

nice one

HAPPY NEW YR MY PEOPLE. i love u all. truly life is good wt solar

Happy New year all.
For issues with dust on panels, just flush with water. A hose connection to discharge of submersible pump could provide good water pressure.

i have 1kw original usa panels, but am getting only 630w max from them...wht could be wrong?

RipVanWink: i have 1kw original usa panels, but am getting only 630w max from them...wht could be wrong?

I suggest u revisit ur installation. review d position if d panels . shading may be a cause. also u should observe some angle of inclination by facing south....I mean a position where d sun shines most in ur area.
all said above assuming u connected d panels correctly.
can u give details of d panels individually and how u connected series /parallel.
what type of controller and wires u used. distance BTW d stuffs installed.

Just to add to what abunafiu has said;
* is your load able to draw more than 630W?
* is your charge controller able to maximize the power of the panel?

all,

happy 2014 to everyone in the house. may all our days be sunny and bright this new year and may we never
walk in the dark, gloomy shadows of years past!

just got back from the village over the weekend and have been offline for a while. that said, its nice to see a lot
of developments on the thread. i'm particularly impressed with salam12 installation. looks like a new solar
convert who has finally decided to take the plunge and he's really done it in a big way. congrats!

[quote author=George_D]all,

Thank you bros. Your believe in sharing knowledge actually spurred me into renewable energy option and I must confess it has been quite rewarding. Been off town for almost 2 wks and wifey with the kids have attested to beauty of 24/7 power supply without noise. Pumping water and washing clothes at will without having to cope with generator wahala.

nirlnd!!!!. m pissed..the whole post i mde explining my spec nd troubles with my panel, which i posted succesfully is no where to be found!..ki where wud i gtet the strength to repost all the info again

i think my battery is prt of the problem, they are wek and doint hold chrage 4 long. i intend to chNGWE them first, and see if there would be any improvement. am torn btw fullriver 200aamp batt 2units and zenith 260amp batt........i lernt fullriver is gel, thus aam leaning towrds it, both batteries are btw 55k to 60k.......can some1 recommend any battery?....also any zenith batt distributor in edo state?

abunafiu,

this time of year is always a big problem for solar harvest all over the globe. if you check back on last year's post
around this time we talked extensively on this issue so its a recurring subject year on year.

here in the south-south we are not left out as we battle on two fronts. on one part is the cloud cover which ironically
is persistent despite it being a harmattan period. on the other hand we have the issue of dust. both of this combine to
make a huge dent on total solar harvest. peeps would think the opposite should be the case though as theoretically
one would expect to harvest more in the dry season as compared to the rainy season but the reality is more like the
reverse.

below pics of snapshot of peak harvest for yesterday and day before.

i must say the meter hub is doing a good job of combining the outputs of the two tristar charge controllers,
so i no longer have any need to do manual additions (thanks again to totalgreen for making this happen)

now, to one of the overriding reasons i went for the magnum above other available high end inverters:

control from the comfort of your bedroom!

more:

so many parameters at the tip of your fingers!

the bmk (battery monitor kit) certainly doing a good job of monitoring the entire system:

the lbco (low battery cut off) setting that saved the day.

in my absence my folks ran the system so low that the voltage dropped to 48v and suddenly power went off.
unknown to them i had set the inverter to cut off at exactly 48v thereby preventing serious damage to the
batteries.

more settings:

@Fikfik, I know am late to the party. Came across your Morning star issue and had to respond because I run into a similar situation. I have a 60A Tristar MPPT, run into the same problem. I managed to get it fixed. I still have some of the transistors that I used to do that do. You will need someone with a little background in electronics to do the replacement for you. I have surplus transistors for the 60A version hope you haven't thrown your CC away.The only unfortunate part is that I live in Ghana.

With regards to Solar harvest-we in the southern part of West Africa have a problem. Because we are on the equator we will have to adjust our panels every 3-6 months or so to get a good harvest. I have attached an angle calculator to help. You notice that the sun is in the northern hemisphere at one time and then in the southern hemisphere at another time of the year. That is-if your building is facing south, you will have it casting a shadow to back of the house at one time in the year and then casting a shadow to the front at another time of the year. To optimize your solar harvest, you will need to use a solar tracker or manually adjust your panels 2-3 times a year

wow..from the solar angle site........it appers that people that plqace their panels on the rooftop directly or on small stnds are obviously not reaping the mximum power from the sun

Well we have to just take it up again.
From 84 back to 66. That's a lot of loss.
But who says we can't do it again?

we have to take it the way it is

This is not easy. Na wa o. Data loss is a great loss. Well congrats to all. I wonder what what it will look like withoutour great forum
