DIY Solar Night Lamp / Mini Solar Street Light using TP4056 board

Another circuit of do it yourself Solar Night Lamp with TP4056 board with Protection Output. I bypassed the TP4056 IC and leaving the DW01 IC for Overcharged and Low Voltage Protection functions. Solar charging current has improved while batteries are still protected.
External components transistor, diode and resistor act as auto on/off function. LED will turn on when there is no sunlight received by Solar Panel.
I used 3.5W/6V Solar Panel that gives around 0.55 Amps of charging current.
3 pieces of 1W LEDs consumed around 220mA (current controlled by bias resistor connected on the base of NPN transistor). They last overnight with 2 pieces of 18650 lithium ion rechargeable batteries.
Note: remove the 2.2k ohms resistor if the transistor is so hot. Solar panel has already an internal resistance that will turn on the transistor.

Ingenious work! Keep it up

Is the benefits of Tp4056 ( charging topologies) gets killed as + output is directly connected to battery for direct charging and not by +B connection which should be the actual battery connection in the board.

Thank you just what I was looking for.

May 12v po kayo nyan sir same circuit po sana

Two 2000mah batteries are connected in parallel and a single 4000mah battery is obtained?

[@edmundbrisenio2286]

Yes

[@emre-uc1zh]

@@edmundbrisenio2286 So, Is the value of the resistor determined according to the load of the lamp? Does the duration of use from the battery depend on the resistance, that is, how is the calculation of the resistance to be selected?

[@miteshdhanani]

If we want to connect a switch to it then

Can use step up booster module for 12v led?

sir ed pwedi ba itong gamitan ng 1 32650 na bat?

[@jasonyee1363]

Can I add in one more battery from the circuit ?

Bu sistem kaç saat aydınlatma yapıyor?

[@thetoolmasterph4848]

Sir can you add a mosfet to the circuit so that it can handle more amps. Thanks sir...

Daryl Paulino yep. Here is the link for higher powered street lights. kzbin.info/www/bejne/rHjah6GJlt2qbc0

What is the backup time?

[@joshrhinbenj]

Si Ed, Where can I buy 3.5W/6V Solar panel in Manila? Cheers

[@edmundbrisenio2286]

Benjie Balighot there is none in Manila. They are online sellers in Laguna or Dagupan

[@Zephieish]

Can you use 1W 12V LED'S?

[@edmundbrisenio2286]

No

[@Zephieish]

@@edmundbrisenio2286 What voltage are the LED's you used?

[@miteshdhanani]

Can we use mobile battery

[@edmundbrisenio2286]

Mitesh Dhanani yes you can.
