How many solar Panels do you need? Here is the first thing to think about when you want solar for your home or business.
Understanding Your Electricity Usage:

Start by gathering your electric bill, which shows your electricity usage in kilowatt-hours (kWh) over a period of time (you mentioned yours gives 13 months of data, but 12 months is typically what you need).
Add up your monthly usage to get a total for the year. In your case, it totaled 95 kWh/day after calculating the average.
Calculating Daily Energy Needs:

I then Divided my total yearly energy use by 12 (for the months) and then by 30 (for the days in a month). This gives you the daily average usage.
You calculated around 7.5 kW as the minimum size of a solar PV system you'd need to cover your energy use.
Considering Solar Panel Efficiency:

Next, factor in the variability of the sun. Since sunlight isn’t always at its peak intensity throughout the day or year, you adjust for that using a multiplier. You used 120% as an industry standard to account for sun positioning and shading, which increased your system size to 9.05 kW. You suggest rounding it up to 10 kW for safety.
Accounting for Battery Storage:

If you want to add a home battery for energy storage, you'll need to size up even more. You used a 200% rule here to factor in both home and battery energy needs. This allows the battery to store excess energy for later use, like during outages.
Peak Sunlight Hours:

Sunlight availability varies by region, so it’s important to know how many hours of peak sunlight your location gets. You estimate around 4 hours per day of peak sunlight in the Midwest/Great Lakes region. Further south, this number will be higher, and further north, it will be lower.
Final Calculation:

Once you have your daily energy usage, adjust for your location’s sunlight availability to calculate the size of your PV system. In your case, after accounting for peak sunlight and energy needs, the base minimum system size would be around 10 kW.
Next Steps:

Once you have your system size, you can reach out to contractors, explore financing, or consider installing the system yourself.
