Once you have an idea of your energy consumption, it’s time to consider the panel capacity, expressed in watts (W). A higher wattage means more power generation, but also a larger size and possibly a higher cost.
There are many free tools available online to estimate the total system capacity needed. Finding the exact system capacity needed can be tricky as many things influence this – geographic location, cloud cover, shade from nearby trees, your power consumption throughout the day, even how your local power company pays you for putting excess electricity back into the grid. When in doubt, consult with a professional installer who can provide a more precise assessment based on your specific situation.
Pick solar panels with the right size and capacity, as it is vital for cost efficiency and ensuring your energy needs are met. By following these steps, you’ll be on the right path to a greener, sustainable future.
