Can I increase my power output from my solar panel using a …
You can''t get power out of nowhere, no matter what you do. So no way you can increase power. Period. Charging time of the capacitor is 5T = 5RC comes from exponential equation, and after 5RC you have 99% charge, usually considered full charge (or discharge, it''s symmetric).
Solar Cell Properties and Design
1. Photons in sunlight hit the solar panel and are absorbed by semi-conducting materials.2. Electrons (negatively charged) are knocked loose from their atoms as they are excited. Due to their special structure and the materials in solar cells, the electrons are only allowed to move in a single direction. The electronic structure of the materials is very important for the process to work, and often silicon incorporating small amounts of boron or phosphorus is used in different layers.
No pre-charge resistor solution | DIY Solar Power Forum
Many BMS''s have a pre-charge resistor built in. For me, with my SunGoldPower inverter''s switch in the off position, I close the breaker on one EG4 LifePower4 battery which automatically uses a build in pre-charge resistor to charge the capacitors in the inverter and is does also prevent a large current from tripping the BMS
SOLAR GARDEN LIGHT
The 10k resistor allows the voltage on the solar panel to rise above 0.7v during bright sunlight, while the 100k discharges the 100p when the voltage is very low and the capacitor holds a charge to keep the transistor turned on when the voltage is "high".

Is a precharge resistor needed with a suitable cut off switch?
The 1000W creates as big of a spark as the 2000W, but it''s higher quality (Victron vs Renogy), so perhaps the caps are bigger or equal in size. If I hook the panels in full sun, I do get some spark, but not as big as the inverter spark. I''ve never tried nor seen anyone mention using a pre-charge resistor for hooking up panels to a charge ...
Solar panels powering a TP4056

Electric Power and Energy | Physics
Electric energy depends on both the voltage involved and the charge moved. This is expressed most simply as PE = qV, where q is the charge moved and V is the voltage (or more precisely, the potential difference the charge moves through). Power is the rate at which energy is moved, and so electric power is [latex]P=frac{PE}{t}=frac{qV}{t ...

Solar Charge Controllers: What They Are, Why You Need ...
Efficiency is low when the voltage of the solar panel is much higher than the battery voltage because the LDO is effectively a variable resistor, so the input impedance is not set to draw power from the solar at the maximum power point. LDOs charge most efficiently when the solar panel is designed with a power point voltage close to the ...
Capacitor Charge Time Calculation
If the resistor was just 1000 ohms, the time constant would be 0.1seconds, so it would take 0.5 seconds to reach 9 volts. If the capacitor was 1000 microfarads, it would take 50 seconds in total. So as the capacitor size increases, the time taken will also increase. If the resistor value increases, then the time taken also increases.
