So recently, i bought a new solar panel. Its capacity is 5W and it is very handy for the summer months in india. It can easily charge a 6v 4.5AH SLA (Sealed Lead Acid) battery. My charging setup is as follows-
Solar panel -> 1n4007 diode -> Battery
The battery can store up to 27 WH and gets charged in one day easily.
I check on the setup regularly with a multimeter.
Lead acid batteries are every well suited to charging with a solar panel since they are not fussy about over charge/undercharge, they can store large amounts of current for a very less cost, and they can be drip charged. The battery in question costed me about $5, very cheap compared to a li-ion solution.
They charged battery is then used to charge various mobile phones as well as for lighting during power cuts. I plan to expand this system with a 12v 7.2 AH battery and a 20 Watt solar panel. Also, i want to upgrade the diode form an 1n4001 to a shottky diode because the voltage drop is much less then normal rectifiers!

hi sarang,
ReplyDeletethe picture shown by you does not indicate where you have use the diodes?
what the use of diodes?
diodes are used to eliminate the solar array,,,
what new in this?

Hi Ajinkya,
ReplyDeleteHere i used the diode to connect the solar panel to the rechargeable battery so that the battery does not discharge it self through the solar panel at night.
Unfortunately the experiment i showed cant be used to eliminate the solar array

Solar panels are very good. They save electricity and money too. Start using solar products guys. Best rates at MyDeals247.com from where I bought many solar products
ReplyDeleteThanks for sharing the useful information. It was really amazing and very informative. Keep sharing more article.
