I am not sure if this is the right place to post.


Let me start if none.


I have been searching ways to convert sun energy to electricity.

All we need :-

1) Solar panel
2) Battery
3) Inverter
4) Most important - PWM Solar Charger Controller



Solar panel
To convert sunlight to DC voltage
Maybe in range 6,12,18,24,48V

Battery
To store DC generated from panel

Inverter
To convert DC in battery to AC sine wave

PWM
Solar charge controller will protect your batteries from being overcharged by your solar panels and it will block any reverse current (from the batteries) as well.

These are all the kits you should have to start a simple DIY solar .

Lets roll guys ?

just planning to install 90W for trial.

for porch area.

hehe

MPPT is more exp i suppose

anybody knows

1) Solar panel 30W , battery 12AH ,
How long does it takes to fully charges the battery ?


2) For a 100w load, how long can the battery last ?

i think these 2 factors are important in determining the battery/ solar capacity and

42AH

meaning the batt can supply 42amp for 1 hour.
after that , drained finish ?

the only thing is got to wait till solar panel price drop !

i hv not connect fan to my car inverter yet.

maybe i shall try ?
