Renewable energy sources like solar and wind are ideal for powering equipment in remote locations. In this article, we’ll outline a step-by-step process for sizing an off-grid solar system so you can generate electricity even when you’re miles from the nearest power line. These types of systems power off-grid homes, as well as a variety of industrial applications where equipment needs to be powered at remote work sites. Common applications include lighting, telecommunication equipment, sensors, environmental monitors, security cameras, traffic signals, water pumps, cathodic protection systems, and anything else that requires reliable power in a remote location. The following guidelines are intended to help size an off-grid solar system based on a given location, energy requirements, and desired days of autonomy (how long the battery bank can supply power before it needs to be recharged). Step 1: Determine Energy Requirements First, you need to know how much energy the equipment uses on a daily basis. This is measured in watt-hours or kilowatt-hours per day. For example, let’s assume the equipment consumes 10 watts of power and operates 24 hours a day: 10 Watts x 24 hours = 240 watt hours per day or .24 kWh per day How do […]
