Need help with solar pannel?
Answer:
Capacitors are probably not what you need. You need three items:
- A battery charger/charge controller
- A 12V deep cycle battery
- An inverter
The solar panel is connected to the battery charger, which controls the charge in the battery. This needs to be a deep cycle type battery, which can stand frequent discharge. The battery is then connected to an inverter which provides you with the 120VAC you need.
It is possible to use capacitors instead of a battery, but the capacitors that are available today can not store as much energy as batteries of comparable size and weight. In addition, battery voltage is maintained at a reasonably constant value as they discharge while capacitor voltage begins to drop immediately when you start to use the stored energy. Than means capacitors require an inverter that can output a constant voltage while receiving an input voltage that drops significantly from the initial value. People are doing research on using capacitors for energy storage, but not much results have been demonstrated so far.
I have worked on a number of solar panel projects. SuperCaps have some application, but I am afraid your really want panels and batteries. There are a number of solar design sites on the web. Use them. Make sure you understand how to use an insolation map. When I first started to work on these projects, I was amazed how quickly things got pricey.
