The Solar panel is just to help out to keep the capacitor charged and it really doesn''t need a lot of power, even if the sunlight isn''t perfect, it should still help to keep the voltage in the 12-14V range But yeah there definitely are some sketchy videos online involving "free energy" with solar panels n super caps and stuff like that, so

Capacitors: Theoretically the only purpose of the capacitor in a solar watch is to store energy, therefore a capacitor with higher voltage (V) or capacitance (F) should work fine. You do NOT want lower voltage. If you need a cell for any other solar watch, Panasonic has a lot. You can also find many on sites like Mouser or Digikey. Share

Thanks Audioguru, I don''t have an issue about the long interval, the only thing I need is that the capacitor should store enough energy to make sound for at lease 2/3 seconds. Regarding the capacitor voltage I will use 1381U which is mentioned in the solar engine. It will apply the capacitor voltage to load on reaching to 4.9V

What size solar panels in watts would be the correct amount for Upper Michigan to keep the system charged and running? (about $140 from Digi-Key.) From 13 to 11 volts you get (4901-3509)=1392 watt-seconds. So you would need two capacitor packs for a total of 116 farads. So that would certainly help with surge and will last almost forever.

A capacitor stores power and then releases at time of need. I am thinking, that maybe large size capacitors may already available in commercial markets. So why do not we use capacitors to hold & store power instead of batteries. Life of capacitors must be much longer than batteries. Any and all comments are welcome regarding the above. Regards.

Big capacitors connected to high-current sources can be dangerous, and I put a lot of thought into how to do it right. The amount of time and even money (each capacitor cost about $40) involved may not pay off in extra battery life. But I''m an electrical engineer and really wanted to do this, and am very pleased with the result.

In fact, when selecting capacitors to integrate with solar cells, several factors need to be considered, including working voltage, energy density, power density, cycle life, and cost. The capacitor must match the output voltage of the solar cell.
Learn MoreThe integration of capacitors into solar power systems stands as a potent strategy for enhancing their efficiency and operational longevity. Capacitors, essentially energy storage components, function by storing and swiftly releasing electrical energy.
Using capacitors with solar panels steadily changes the performance and longevity of the solar system. Solar panels produce energy from the sun, and the system converts DC to AC electricity. These all functions depend on capacitors, and it is a common scenario of using capacitors in a solar system.
Capacitors with high energy density and power density can store more electric energy and supply current to the load faster, improving the efficiency and performance of a solar cell system. Additionally, cycle life is a key index for the stability and reliability of capacitors.
The supercapacitors can discharge the high-voltage current from the solar cells, which is much higher than the loading current. It will help the system when there is an intermittent load. Solar power generation depends on the PV cells, and it is the most common type of solar energy production.
The capacitor must match the output voltage of the solar cell. Since the output voltage range of solar cells is wide, the selected capacitor should be able to function correctly within this range. Energy density and power density are important indicators of capacitor performance.
So, capacitors play a vital role in solar power generation and PV cells. Users can employ a PV inverter or capacitor to convert the power easily. On the contrary, capacitors can increase the usability and probability of producing maximum power in an off-grid solar power system.
