Update 2: Installation of solar panels and the inverter
Yesterday marks the third day of the installation process of the STEEM Lighting Africa project and it was the solar PVs installation day!
I first started by hiring an electrical ladder. This would help me gain my balance while installing.
I had to check the stand again to be sure it would be strong enough to carry all the 6 panels.
One other thing I put into consideration the height and the wind.
So, While installing this stand, we used much of cement and gravels than sand.
Next was the installation of the 200W Canadian solar PVs. The connections here was in parallel because it's a 12V system.
The 6 panels will give the system a super charge function.
They can NEVER experience power failure due to low charging factor.
I managed to take a selfie... despite the heat from the panels.
By the way, did you know that this panels generate much heat..? Well, it does.
After the whole solar mounting, I stepped back to check the arrangement, and I noticed some irregularities in the arrangement, so I tried to adjust them.
Next was the connections of the main system inside and that is the battery and the inverter.
The whole installation and test running took me about 5 hours and at the end, everything was successful.
System Configuration:
- Inverter: 3KVA
- Solar Panels: 6 x 200W Canadian panels (Total: 1200W)
- Battery: 1 x 220Ah Tubular battery
- Charge Controller: 60A MPPT
System Performance based on yesterday's observation:
Peak Power Output is about 1200W, while daily energy yield is approximately 5.5-6.5 kWh (though this would be depending on solar irradiance and temperature).
The battery state of charge (SOC) was about 80% (average) after a half day of charging. This is so because the battery is new and I had already charge the battery 2 days ago using my spare unit at my shop. So, technically, if I say "after charging the battery for a full day, I got 80% (SOC)" then I'm still correct.
And now?
The work is done! This mark my 4th successful solar project using STEEM througb the help of friends.
I want to use this medium to thank all the friends who have been supportive throughout the whole fund raising stage till this moment and the big whales.
Guess what is remaining now..?
well done man, number 4 is pointing up, maybe number 10 of the installations will come soon around one of your corners ;)
what makes me wonder did you realy put the panels on a wooden frame ?
I hope my friend you have calculated the wind load correctly and carefully, because you are very near to the building and when there is heavy wind you might end up with a flying solar instalation (not a swimming one) that would be something new and very dangerous I saw a sign at the wall what makes me think that the place where you mounted it is a school, so if something goes wrong there may be a lot of kids in danger !?
so here is my solution for it (see the pic),
yes I know its more costly but hey security of children is always highest priority , and at least you would signaling to your custormer that your a very serious professional.
...sunny greetings from the south of Spain ;)
Thank you very much for those kind words!!
The idea you brought here is so brilliant, trust me. Howeveer, I had considered this more than 10 times..., infact a friend even mention that same thing to me before I even started the installation.
Those panels are firmly tightened on the woods. And as for the galvanize pipes, I had buried like 2 feet on the ground and they are well casted.
By tomorrow or next, I will weld iron around the four pillers...., such that, it will form a chain.
Thank you very much for your suggestion. Infact, it's a big lesson. I will sure use it in subsequent time.
You are 100% right.
thank´s for taking the time to read and think about my suggestion for a maybe "better and safer" mounting methode. If you considder this for upcoming new installations you can build a kind of mountingkit what you use for yourself or maybe think about prefabricating such a kit and sell it to others, just a idea to ramp up your business you deserve it for your restless work ;)
Sure thing, I will consider this in my future plans. Thank you so much.
you´re welcome ;)

A beer ;-))
Let me ask you: these panels really generate so much heat...? Is that normal? I mean, here they are usually mounted directly on the roof surface - wouldn't that be... dangerous? And - if the radiation is converted so significantly into heat, isn't the effectiveness rather modest?
hehe, klar hier trifft Energie in Form von Licht auf die kristalline Schicht der Wafer und dort wird die Energie direkt in Strom umgewandelt was Wärme erzeugt, normaler physikalischer Vorgang, gefährlich ist das nur wenn du leicht brennbare Materialien direkt darunter hast die könnten sich entzünden.
Aber normalerweise ungefährlich hier in Südspanien wo es im Sommer Außentemperaturen von 45-50°C hat (auf den Flächen noch mehr) ist meines Wissens nach noch kein Solarmodul fortgeraucht also verbrannt oder ein Feuer wegen der Hitzeeinwirkung der Module entstanden.
Es ist ja auch immer ein wenig Hinterlüftung da durch Wind, die Temperatursituation dürfte vergleichbar sein mit Nigeria, und in D werden Module nur im Extremfall 1 Tag im Jahr überhaupt mal 70% dieser Temperaturen erreichen.
You guessed right!
Yes, they do...
While solar panels do generate heat, it's a normal and manageable phenomenon.
Proper installation, thermal management, and roofing materials all help to minimize the risks associated with heat generation. Most of these panels comes with heatsink which helps in cooling the heat. However, this can't be effective 100%..., there would still be a little amount of heat...,but that's not a big deal.
You won't feel it inside the house..., I felt it while installing because I was too close to the panels.
