Secondly a battery can regulate the power going in to the appliance at a constant rate. Solar panels might not generate enough wattage to directly power an appliance, but they can build up a higher wattage via a battery. There are a couple of reasons for having batteries. Solar panels are commonly used to charge a battery – not to charge a device directly. The electric charge in Amps is equal to the energy in Watts divided by the voltage in volts (V):įind the electric charge in Amps when the energy consumption is 300 watts and the voltage is 240 volts. You can then use the equation Watts Volts x Amps so 240v x 1.5amps = 360 Watts. 240V and the Amps AC it draws such as 240V – 1.5A. If your device doesn’t have the Watts labelled on it, then it should at least have the input Volts i.e. The energy in Watts is equal to the electric charge in Amps times the voltage in volts: For example:ġ0 watt device used over 3 hours equals 10 x 3 = 30 Watt How to convert Amps to Watts To calculate the energy you will use over time, just multiply the power consumption by the hours of use. The power consumption of appliances is usually given in Watts. I will try my best to answer everyone.Ī larger solar panel will collect more energy in less time, but just how big does the solar panel need to be? If anyone has a question pop it in the comment section below. Knowledge is key when setting up your rig for solar so the more information you have on each and every one of those home comforts devices you plan to take away with you the better. So you want to set your rig up for Solar but you are not sure what size of set up you need? This blog is designed to give you the tools needed to be able to work out exactly what are you are drawing from your rig's batteries and what type of solar set up you need.
