I am interested in making a solar panel for domestic electricity.plz guide me and also tell me about its term?
Question:
Answer:
Some rough figures:
At $10 per watt, you'll need $13,000 in solar cells. Then there's batteries, power management...
It'll take years to recoup the investment. Consider.
Ok, the solar panels will normally generate 12 volts DC, you can either then run a static inverter to raise to 110volts, the output current will be somewhat less than 1/12th (due to losses) or you can run a motor dynamo - this is lossier though.
You can connect the panels in series + to - till you reach the end - 10 panels will give you 120v at the rated current of ONE cell.
Power - Watts - W
Current = Amps - I
Voltage = Volts - V
W= V*I
V = W/I
I = W/V
So 1300 watts will be a running current of approx 12 amps (ignoring Power factor) BUT the start current is likely to be double that, so briefly you would need to supply 24 amps at 110volt, although most likely your AirCon will be 220 volts. In that case you would need 19 panels.
This solution would still require a static inverter as the panels are DC (Direct Current) and the AirCon requires AC (Alternating Current)
So if your panels give for instance 1 Amp
you will need
12 rows of 19 panels to run the system (228 panels)
Each row of panels will need a hefty 12 volt battery to store its charge when able to do so - say 100 AH (amp hour) and for starting the system
The static inverter or motor generator will need to be able to provide 2600 Watts briefly and 1500 watts continuously.
And what about at night??
The 100 AH batteries? well they will probably allow about 4 hours absolute max of running time. You will also need Deep Cycle batteries, (ones that are designed to charge and be discharged continuously - NOT Car batteries)
Still want to do this - what about a small LPG or diesel generator?
