![]() Unlike amps, watts are cumulative over time. Simply round up all your appliances and look at the label that tells you what the wattage of each one is. You can gather this information in the same way you calculated your peak amp draw. Let’s use the example above for the weekend camper. Typical RV solar batteries have a voltage of 12 volts. To determine what hours per day, you simply take your daily or weekly amp hours and multiply it by the voltage of your battery. This is normally more than enough for most RV owners, but you may need a large system if, for example, you’re traveling as a large family or you have more appliances than usual. Portable solar power stations, like the ROCKPALS 500 Solar Generator have a current of around 6 amps. It’s like trying to take a shower with a garden hose on: neither is going to get enough water. If not, the amount of power each appliance will receive isn’t going to be enough to run properly. If you’re trying to power two appliances at once, you need to make sure your system has the current capacity to allow for this. How wide the pipes are-how quickly the water can flow-is the current. When you turn on your faucets, the water has to flow through the pipes the pour into your sink. The wattage of the system is how big the reservoir is. It’s more a representation of how large the stream of charged particles that carry electrical current is that flows through the system. This value isn’t cumulative like wattage is. The total amps of your system represents its current capacity. A microwave for example can use 8 amps per hour, but thankfully we don’t typically use them that often. Some appliances might require a lot more amps if you use them for prolonged periods. Lights and other small appliances like ceiling fans will use about half an amp. If you are in a cooler area, then you can scrap the fan from this example. Your lights and fan will only be utilized during the night, which is typically around 6 hours per day. Using a TV for this period equates to approximately 0.5 amps per day. Most RVs have 12-volt televisions that are usually running for about 3 hours or less in a day. ![]() It can be a bit of a headache to calculate each appliance, so we have made it easier for you by giving you an estimate of the average RV owners' most utilized appliances. ![]() Īll you need to do is list everything appliance that you use through a 24-hour and the amps that will be used in the same 24-hour period. You cannot simply install any number of solar panels without understanding the electrical power requirements of your RV and the full sun hours per day. So, sit back, and let’s start our journey in the understanding of renewable clean solar energy.īefore we get into how to calculate the solar energy needed for your RV, you first need to tally up everything that your solar panel will be powering. The following guide will tell you everything you need to know about solar calculations for RVs. You will even be able to scale it down and calculate the solar energy required for specific electrical devices. Once you get the hang of these calculations you will be able to implement larger-scale systems such as your home or business. Thankfully, we will show you how easy it is to calculate the required solar energy for your RV, which can additionally be used to calculate other systems and devices as well. They’re often caught up in the theory of these calculations, rather than the solution. Many solar guides tend to overcomplicate these simple-to-understand calculations and it’s enough to scare people away from powering their homes with sustainable solar energy. ![]() There are a ton of advantages associated with solar energy.ĭeciding to switch is the easy part but understanding specific solar calculator equations can be a bit daunting for solar newbies, especially when wanting to power smaller systems, such as an RV. Deciding to go solar is one of the best energy decisions you can make. ![]()
