You prepare a large meal and ended up using the garbage disposal and then everyone relaxes under the overhead fan because it's a hot Arizona night in the desert. They may arrive late at night which means you had to use the outdoor light for 15 or 20 minutes when they arrived. However, lets now say that you have some family or friends visiting your home. Many people think it would be ok to leave these items off of the calculation because they are rarely consuming power. Lets also say you have a ceiling fan that rarely gets turned on and a garbage disposal that rarely gets used because you compost most of your scrap food. Some people will either forget to list that light or decide that it's not important to include it in the design process. Most homes and RV's have an outdoor light but it may not get used very often. Lets examine some electrical loads as an example. The more accurately you fill in the calculator, the better your system design will be. If a device is drawing energy, no matter how small, it will have an impact on your solar system. When filling in the calculator values, it's crucial that you do not leave anything out. The calculator helps us determine how much energy your home will need. An electrical system does you no good if it can't provide you with the necessary energy to properly run your home, RV or boat. If you are not storing enough energy, you will decrease the life of your batteries, possibly ruin your batteries and most importantly, your power will eventually go out. Off the grid systems must utilize batteries to store DC power from the solar panels and convert it to AC power with an inverter. When designing an off-grid (not connected to utility power) solar or wind power system, it's very important to have an accurate estimate for how much energy you need.
