Determining the number of solar panels you need from a solar installer involves several factors, including your energy consumption, available roof space, and budget. To start, assess your household’s energy usage by reviewing past utility bills to understand your average monthly kilowatt-hour (kWh) consumption. Next, consider your roof’s orientation, tilt, and shading to determine its solar potential. A south-facing roof with minimal shading typically receives the most sunlight and is ideal for solar panel installation. Additionally, calculate the available roof space to determine how many solar panels can be accommodated.
Once you have an estimate of your energy needs and available roof space, consult with a solar installer to conduct a site assessment. During this assessment, the installer will evaluate your roof’s suitability for solar panels and provide recommendations based on your energy goals and budget. Solar panel systems are typically sized in kilowatts (kW), with each kW of solar capacity generating a certain amount of electricity per year. Based on your energy consumption and site assessment, the solar installer can recommend the appropriate size of the solar panel system to meet your needs. The number of solar panels you get from a solar installer will depend on various factors, including your energy goals, available roof space, and budget constraints. Working closely with a reputable solar installer can help you design a customized solar panel system that maximizes energy production and savings.
