Calculating the number of solar panels you need depends on a few factors. First, determine your daily energy consumption in kilowatt-hours (kWh). You can usually find this on your electricity bill. Next, consider your location; the amount of sunlight you receive impacts your panel's efficiency. Then, check the wattage of the solar panels you're interested in (https://a1solarstore.com/solar-panels/maryland.html).
