When you are going to need much panels. Yes there's a time we should install Many panels. 1. When you are powering a house or office. Without using battery. Much panels is needed. And the power is inverted directly . 2. When you add more battery to the setup. 1 Like |

So we need as much panels if we are adding many battery. Sometimes, the power is inverted from panels. Especially during the day. This works only in the day time. You won't have light at night. You need power from battery to have light at night when there's no sun. 1 Like |

So let's talk about panels. Solar panels is graded in watts. It's. Usually have vmp= maximum voltage And Imp = current. Remember that power equals voltage x current.

Re: My Solar Set Up Journey After A Year. Very Cool by eliok(m): 6:14pm On Jul 15, 2021 |
Panels are graded in 10watts , 20 watts, up to 280 watts. For a start, get one panel. Atleast. We should be charging our battery from the sun. That's why we call it solar system. Start with a 100 watts panel 1 Like |

We have two types. Monocrystalline panels And polycrystalline. They work the same. But mono is more expensive. Panels are rated in 12v . Higher watts panels are rated 24v. See pic of both panels types. 1 Like

Next we shall make on to the connection |
Re: My Solar Set Up Journey After A Year. Very Cool by eliok(m): 2:58pm On Jul 17, 2021 |
Solar panels are rated by volts and watts. E.g 18v 80 watts And so on. Now Series connection is address adding voltage together. 12v + 12v = 24volts. Parallel connection is 12v 5amp + 12v 5amp = 12v 10amp. This mean that in series connection we add the voltage . But in parallel we I ncrease the current. 2 Likes |

Panels are mostly connected in series. So that we use a normal wire. Try to add up in series so that we won't need fat wires. 1 Like |

How many panels do I need. We shall calculate this in a moment |
Re: My Solar Set Up Journey After A Year. Very Cool by eliok(m): 1:07pm On Jul 18, 2021 |
Now to calculate how many panels you need, Start from your proposed battery capacity. To power a laptop for 6 hours Look at the laptop charger. Usually 19v 3.5a Power = V x I So 19× 3.5 = 66.5 watts. This is just for one hour. So for 6 hours we have 66.5 x6 = 399 watts. Now a 12v battery is sometimes 12v 100a Power from battery is 12×100 = 1200watts. |

The law of efficiency is that you can't use all the power in a battery. Any kind of battery. For lithium (laptop battery) You can only use 80% For car battery 50% For deep cycle battery 50% 1 Like |
Re: My Solar Set Up Journey After A Year. Very Cool by eliok(m): 1:12pm On Jul 18, 2021 |
So if you build or buy a 600 watts battery. If it's a deep cycle battery, only 300 watts is available. WHY? For the battery to last. This is known as depth of discharge. 1 Like |
Re: My Solar Set Up Journey After A Year. Very Cool by eliok(m): 1:17pm On Jul 18, 2021 |
So our car battery of 12v 100a which is 1200 watts can only be used of half of it's power. From our initial calculation, We need 400 watts to run laptop for six hours. So if we have 600 watts of battery available, to that should definitely do. Remember that solar panels are rated in watts too. My personal rule is multiple the watts of your panel by 3. For example, 100 watts panel will supply 300 watts power in sunlight. That's for 1 hour of sunlight. So an 100watts panel can charge your 12v 100a battery for 3 hours. 2 Likes |

Please who is your 18650 battery cells plug? Does he also have the 32700 LiFePO4 spec.(shown below) ?

Re: My Solar Set Up Journey After A Year. Very Cool by eliok(m): 9:52am On Jul 22, 2021 |
Hunkyimage:those battery are good. I go with watts popular also. 18650 is popular and you can buy them anywhere. But this 32700, I don't have a seller. Use jumia or other ordering sites to find sellers for it. |

Very informative, am also trying to get into solar energy, I definitely prefer lithium ion battery, but there are lots of fake Chinese lithium battery, especially here in naija. Do you usually buy yours from aliexpress? Also how do you go about connecting the lithium battery? Spot welding or normal soldering? |
