I have an urgent requirement for a PCB design for a solar charge controller system to control the charge to a battery used to drive a string of 20 RGB LEDs.
The solar panels used are organic printed solar panels with very low current rating (around [url removed, login to view]) and Voltage of [url removed, login to view] in indoor lighting conditions.
This is to power an indoor lighting system in a store/supermarket made up of small RGB leds that could possibly light up when it detects motion as well as in short intervals of time if left undisturbed. It will be mainly powered by a small lithium polymer battery, however, the low power solar panels need to be used to trickle charge the battery to ensure that the lighting system remains functional for the duration of its use or as long as possible. An MPPT can be used to maximise the charge absorbed by the panels. And LED drivers can also be used to control the leds.
I also require the PCB design preferably in Altium to create a simulation of the solar panels and get various testing simulations before the PCB is sent for printing.
I have attached my project proposal along, please have a read:
Power storage, management & supply system for Organic Photovoltaics
The basis of this project will be to design a high efficiency solar charge controller which would function as an energy management system to harness low level diffused light indoors via the OPVs and store it in small, portable multi-functional lithium polymer batteries. This charge controller will also constantly manage the power delivered to the lighting system via the battery and ensure a prolonged battery life for the entire intended duration of the use of the application.
Due to the extremely low efficiency of the organic solar panels, one of the main challenges of this project will be to harvest enough power from indoor lighting to trickle charge the battery and maintain sufficient charge to successfully power the load for the entire required duration of its use (roughly 3 weeks).
This lighting package can be used for a variety of purposes with indoor marketing applications being the main focus in its design. The theory and circuitry used to develop the charge controller should be easily modified to satisfy higher or lower energy requirements and can be tailored based on the intended usage to get a completely customized power management application.
Programs such as Eagle CAD, Altium are to be used for the circuit design and optimization.
** please get back to me as soon as possible for any further information, I urgently require assistance with this since it is a project** thank yoi
