I power my camera charger using solar panels. How can I do. I specifications, technology, etc?

You need discover what is the peak voltage and current needed to charge the camera. Assuming that the camera uses electric current, then simply multiply (x voltage current) on the numbers to calculate the power required. This is the power (specifying the amount of energy generated) for its solar panel. Voltage definitely be in units of V, if the units is A, then the power is measured in W, if the current is in units of MA, then the power is calculated mW (or 1 / 1000 W). Stress is another specification for solar panel. You do not have to exactly match the power and voltage spec, but the panel should have voltage and power larger than that obtained from calculations. This is the formula of a simple solar panel without maximizing power. There are units called maximizer of power that will become the solar panel voltage and current to another set of voltage / current that matches your needs. If you choose to use a solar maximizer not is necessary to match the voltage, but you still have to compete with power. The result of the use of a maximizer of power will help to reduce size by 10-30%, but for this application, it is not worth the effort. You can get information directly from the tension of the wall charger that came with the camera. The information you are looking for is "DC output voltage. If, on the wall charger, is written: "Output Voltage AC ", then probably unlikely that you will be able to use a solar panel as the solar panel generates DC output. If you are still trying, with the risk of damaging your camera, then use the same formula to calculate the power, but divide the final answer by 2. Use the "output voltage AC "number and the voltage specification. If you charge by plugging the camera into the computer, then the specifications for voltage is 5V. For the level of current needed to charge the camera, it's harder. The wall charger give a specification of the output current (right next to the DC output voltage), but this probably 10 times greater than what is used to charge the battery. You can still use this to calculate the power of your solar panel, without risk of damage to your camera, but you will have a solar panel 10 times larger than they really need. An alternative way to estimate the current is to get the battery capacity in units of mA-h. Also, get the information in the manual or on Your Own observation, in terms of time (in hours) it takes to charge the battery from full discharge. The current (in units of mA) is obtained by dividing the battery capacity by the time it takes to load the camera.
