Solar Cost

Cost per watt, what's inside a quote, financing traps, and how to tell a fair Texas solar price from an inflated one.

Solar pricing is opaque by design in a lot of the market. The fix is simple: convert every quote to cost per watt and compare only that number.

Cost per watt is the only fair comparison

Divide the contract total by the DC system size in watts. Texas cash purchases cluster between $2.45 and $3.10 per watt. Anything above $3.40 usually reflects financing fees or a high-acquisition-cost sales channel.

Where the money goes

Hardware is under half the bill. Labor, permitting, and sales cost make up the rest, which is why a smaller installer with lower overhead can quote the same equipment for thousands less.

What legitimately raises a quote

Some price increases are real work, not padding.

  • Main electrical panel upgrade: $1,800-$4,000
  • Tile or slate roof: added labor hours
  • Multiple small roof planes and steep pitch
  • Ground mount with trenching
  • Coastal wind loading engineering
