HOW MANY SOLAR PANELS DO I NEED?
How to calculate the right number of panels for your system:
1. DETERMINE YOUR ENERGY USAGE
The first step to determining how many solar panels your home needs is to understand how much energy your system needs to produce. Take your total usage over the past year in kilowatt-hours (kWh) - this figure can be found on your utility bill or online account.
2. DETERMINE YOUR AREA's PRODUCTION RATIO
The same solar system will produce differently in different areas, based on its exposure to the sun. The average production ratio in the United States ranges from 1.3-1.6. If your roof is in a sunny state, like California or Texas, with little shading, take the higher end. If you're located somewhere with less sun exposure and more cloudy days, like most northern states, take the lower end.
3. FACTOR IN YOUR PANEL WATTAGE
The final piece of the equation is the wattage of the panels you plan to use. Once you have all three of these numbers handy, simply plug them into this formula:
Number of panels = production goal / production ratio / panel wattage
Take a look at this example for a California homeowner, who wants to offset 100% of their 10,000 kWh annual usage, has a roof fully exposed to the sun (meaning a production factor on the high end of average, at 1.6) who is considering a system with 450 watt panels.
Number of panels = 10,000 / 1.6 / 450
Number of panels = 13.8 panels
In this case, a 14-panel system would offset just over 100% of the homeowner's annual usage.
4. Adjust formula BASED ON GOALS
Once you have an understanding of the amount of panels you need to offset your current usage, consider additional variables and circumstances.
For example, if you plan to purchase an EV or install a pool, you may want to oversize your system to account for the additional usage those will incur. Or, if you see that you'll need more panels to achieve your production goal than your roof will hold, you may want to consider a higher wattage panel.
