Force voltage to 5V or 0V from solar panel
The solar panel I have is described as 10W 12V, but it seems it can output less than 12V, hence the question about handling lower voltages. Yes, 10W at 12V is what it''s going to produce under ideal conditions -- that means something approaching bright sunlight (if it''s properly specified it''ll tell you at what irradiance it delivers that amount of power).
Serial vs parallel Panels
That panel will have (2/3Vmp - 0.6V) x Imp of output or about about 65% of full output while the unshaded panel will have it''s output reduced to (2/3Vmp - 0.6V) x Isc since voltage will also be reduced but current can increase from Imp to Isc in partial compensation.

6 FAQs about [Solar panel output 6V reduced to 5V]
Can you reduce solar panel voltage?
And that would cause problems. So can you reduce your solar panel voltage? The easiest way you can reduce your Solar Panel’s Voltage is by using either an MPPT Charge Controller or a Step-Down Converter (aka Buck Converter). Other solutions are to use resistors or modify the solar cells’ connections via the junction box.
How much voltage does a solar panel produce?
When the light hit them, they collectively produce voltage. Voltage production depends on environmental factors and various things. Anyway on average your panel would produce slightly half of your panel’s cell count. For example. You have your standard 32-Cell panel. It’ll be outputting 14V to 15V.
What if the voltage is not 5V?
Any more or less current than that, and the voltage will not be 5V. Most circuits are not like that. Take a diode in serial connection. An alternative to the suggestion from @jremington would be a linear low dropout regulator like mcp1700-5. This could be smaller and less expensive. Two capacitors, for example 1uF, would also be required.
Does a linear voltage regulator protect against undervoltage?
I have a linear voltage regulator that ensures the voltage is not more than 5V, but it doesn't protect against undervoltage when the solar panel outputs a voltage lower than 5V + regulator dropout voltage. Would a Zener diode with a 5V breakdown voltage after the regulator work ?
Will a silicon diode work with a 6V battery?
A regular silicon diode will drop about 0.7V and almost anything rated for 5V will work with 5.3V. But the battery won't be a constant 6V. The voltage drops as the battery discharges. A standard voltage regulator has a "drop out" voltage where it stops regulating.
Can a solar panel draw more than 150 mA?
It will never draw more than 150mA. The solar panel I have is described as 10W 12V, but it seems it can output less than 12V, hence the question about handling lower voltages. Ideally, this circuit is always on. It will be "asleep" most of the time, only sending sensor data through wifi once an hour.
