Namzy: For how long have your luminous batteries been serving you? I use similar batteries so i want to know if they're reliable as I've been made to believe

ojeysky: So I am starting with 4 250W flames panel. I have gotten an SPD as well. Now am wondering what kind of cable I should procure. My colleague said I should get a 6mm amoured cable which has both negative and positive and earth. Is that the right cable for my setup? |

Re: Solar Energy, A Complement To FTA by mctfopt: 9:54am On Jun 22, 2019 |
ojeysky: The cable size you are asking of is it for the connection of the PVs to the solar charge controller? If yes, what's the distance between the PV and the charge controller? |
Re: Solar Energy, A Complement To FTA by ojeysky(m): 10:16am On Jun 22, 2019 |
mctfopt: Yes and the distance is about 12 meters. Please kindly also recommend if I should get a circuit breaker and the specification. Fyi I already got an SPD. Thanks |

ojeysky:There's an app on playstore called SOLARCT. It's a nice app and have calculations for your needs including solar panel tilt angle. I think the developer tried with that app 2 Likes |

Trippledots: It says MPPT, there's really no way I can verify though. When we had it in service, our panel voltage was about 65V, feeding into a nominal 48V system. |

Namzy: Okay thanks, found the tool useful. I have ordered a 10mm 2 core amoured cable. Meanwhile has anyone used sunfit solar panels before? Anyone with experience of it compared to flames will be appreciated. |
Re: Solar Energy, A Complement To FTA by mctfopt: 10:04am On Jun 23, 2019 |
ojeysky: OK. I'd suggest you use a cable up to 10mm, just buy the flexible copper type mostly used by welders. The Voc determines the minimum voltage rating of the disconnect switch: for a 14 series 36v PV system the breaker disconnect voltage will be 14 × 36 V = 504V, so a 600V dc breaker will do. As per the current, if Isc of each panel is 8.5A as they are in series the maximum current obtainable is 8.5A, you'd multiply this by 125% which gives 10.625A which you can round to the nearest standard current size of 16A. So you'd require a 600V 16A dc breaker for this configuration. 1 Like |

mctfopt: Thanks I have an SPD that has 600Voc, is it the same thing with what you've stated above? Here is the reference of the SPD I have: https://www.otowadenki.co.jp/eng/products/pdf/LS-YPV6012S%20%20LS-YPV10012S.pdf Regards |

Namzy: thanks for sharing. its also available on apkmirror, in case you wish to match different versions. its true, it is quite a resourceful app. has sections for cable size, panel spacing, basic calculations like how to connect batteries in series/parallel, running hours of battery bank based on load in use, connection of panels, voltage drop e.t.c . much better than some paid apps like PV toolbox. its best used with a phone that has a magnetic compass. a similar apk is called "photovoltaic power plant/SOLARPE" by Pedrot Garcia martin. it also helps calculate spacing for multiple strings of panels either on the ground or on roof tops. it also has an inclinometer to assist in getting correct angle of tilt based on your GPS coordinates. it fetches your insolation data from NASA website. (pvgis Africa apk will do the same, it links to the website to accept long/lat inputs for your location) there is also an app (SUN POSITION DEMO & SUNCALC) that allows you to check possible lines of shading on your site as the sun passes overhead during the day. you pay a token to unlock features to save sun path for any day of the year. default status is only for the current day when in use. it gives sunrise & sunset times, but the sun path feature is most welcome when choosing where to site your panels. hope this helps too. 2 Likes |
Re: Solar Energy, A Complement To FTA by mctfopt: 6:00am On Jun 24, 2019 |
ojeysky: The calculation is just for the setup I described. You can always interpolate with your own specific setup data to get what you require. I hope this helps. |
Re: Solar Energy, A Complement To FTA by ojeysky(m): 6:38am On Jun 24, 2019 |
mctfopt: Sorry I think I may not have asked my question correctly, is an SPD same thing as circuit breaker? |
Re: Solar Energy, A Complement To FTA by kiekie1(m): 9:56am On Jun 24, 2019 |
lexi28: Good stuff ! It's a very useful app.. I mostly use 7-10° tilt with aid of angular solar support for steep slope roofs ! Very steepy roof installations face a lot of losses unlike flat roof designs to be honest ! DNT know if am the only one>> when I sight building designs with high key poles ,I mostly frown whilst calculating pv losses ![]() 2 Likes 1 Share
