How to Calculate Solar Cost - SRoeCo Solar

Step 2: Estimate your cost per Watt installed. Hint: If solar is popular in your state (CA, CO, NJ) and you have asphalt or composite shingles, then use $4-$6/W. If solar is less popular in your state (VA, TX, MI) and you have a tile roof, then use $6-$8/W. If you're unsure, $5.5/W is about the National average.
