Sola kwa ajili ya fensi ya nyumba

[fimboyaasali]

kama kuna mtaalamu wa sola,naomba anifahamisja ninunue sola gani kwa ajili ya fensi ya nyumba ya kuishi

Mcheki USTADH ARABI SAIDI ndio ishu zake hizi.

inaweza kua stand-alone DC system au DC-AC kwa fence pekee.

Only performance matters in either way.

Ku run dc power direct kutoka kwenye solar—>battery—>controller —> DC bulbs is more preferred kama distance ni fupi as DC losses inaongezeka with distance. In this way it seems DC system haiwezi kutumika kwenye fence. Unahitaji DC-AC kwa ku integrate inverter as AC hai suffer sana na losses kama DC.


In DC-AC hapa utatumia bulb za kawaida mradi ziwe weather proof.

System sizing matters otherwise utajikuta bulbs zinazima saan 4 usiku.

You could do this:

1. Determine points za bulbs kwenye fence
2. Number ya bulbs na watt zake and hence total watts e.g bulbs 10 mara watts 7= 70 watts
3. 70watts i run for whole night thats 70w x 13.5 hrs (I’ve added 1.5hr as most places around 1700 jioni jua limesha disappear and solar can’t chaji anymore)
4. That’s 945wh sawa na roughly 1kWh unit moja usiku wote.

5. Just allow 85% system efficiency, it’s 1.2kWh needed.
6. 1.2kWh ni equivalent na battery la 100Ah 12V

7. Solar panel? Here is where most people messes with calculations

Most solar companies hua zina enda na mfumo wa taa. Yani unauziwa batteryna solar based na requirements za taa. Which is wrong. Matokeo yake mfumo wa solar unaanza kuzimazima baada ya mienzi miwili. They don’t consider system sustainability.

Ili solar system idumu maamuzi yote yako kwenye battery. Hasa DoD na cycle life.

Kama battery limekua rated hivi
—C20 (can provide (Ah/20hrs) current for 20 hrs continuously without being charged)
—100Ah, 12V
—Initial current 50A (internal chemistry shouybe charged with 0.25C current for better battery health)

Hence it’s crucial that everything be rated solely on the will of battery ratings.

solar battery nyingi ni deep cycle lakini maisha yake yanategemea sana usizidi 50% ili battery iishi rated life cycles.


Am gonna skip some technical details here and conclude that

Kwa 70watts for 13.5 hours continuously for a sustainable system
1. 150Ah
2. 200Wp
