6 FAQs about [Scrape the solar panel to get the voltage at will]

Why is my solar panel not generating a lot of power?

The issue is that the current the solar panel provides is proportional to the light it received and the only way to keep extracting the maximum power from the solar panel is to adjust the load to keep to solar panel voltage around 6V which in my case is controlled by reducing the charging current.

How does a PV panel affect a sapv system?

The SAPV system will be affected due to the short circuit current of the pv panel (defined by the irradiance and temperature) and the load voltages. The control signal u is generated by the SMC based on the PV current and voltage. The SMC derives both the PV voltage and current to construct the switching function.

How are PV current and voltage obtained?

The PV current and voltage are obtained through the current and voltage sensors. The output of the two sensors is then transmitted to the microcontroller of the Arduino UNO board. During the acquisition process, the data obtained are stored and plotted in real-time in the Excel spreadsheet. This project is linked to this research paper .

How much power does a PV panel produce?

From the experimental results, it can be seen that the PV panel produced a maximum power of 17.07 W at "15h14min02s" when a voltage of 14.15 V and a current of 1.20 A appear. Subsequently, the output power is tends to a minimum value 822.2 mW when there is a voltage of 18.23 V and a current of 45.1 mA.

Can rprog be used to charge a solar panel faster?

Modulating the charge current using RPROG will not help you charge your battery faster at all. Just set RPROG for the sunny day maximum (whatever that is). If you want to extract maximum power from the solar panel, you need to use at least one DC-DC converter, and in that case, it would probably not make sense to use a linear charger.

What if my solar panel is 4V & 6V?

It means that if your battery is ~4V and your solar panel is ~6V you are wasting around 2V*current as heat. Even if you manage to extract the maximum from the panel, the energy loss is high. Consider using a switching regulator, or make your own (buck) with atmega, it is a simple circuit and can have an efficiency of about 90% in any load case.
