The crew
The peopleon the ladder.
SD Solar is a residential solar installer working across Texas. We size the system from your last twelve bills, finance the whole of it at 100%, and hand you one page to sign.
The whole business is built around one number that scares people off before they ever call: 620.


Why we start with the credit score
Most Texans whocould go solarnever ask.
Somewhere along the way the trade convinced people that rooftop solar was a thing you bought with cash or excellent credit. So homeowners with a 640 look at a $28,000 sticker and stop reading.
The lenders we work with approve at 620, finance the system in full, and take no down payment. That is not a promotion — it is the ordinary residential product, and it has been for years. The gap is that nobody says it out loud.
So we say it out loud, on the phone, in fifteen minutes, before anyone climbs anything.
If the roof issound and thescore is 620,the answer is yes.
What we hold to
Five things a homeowner can hold us to, written down so you can quote them back.
- 01
We read the roof before we quote
Satellite first, then a ladder. Pitch, decking age and shade determine the system — not a target price.
- 02
We say no when the roof says no
Under eight years of shingle left and we will tell you to re-roof first. That conversation is free.
- 03
The paperwork is ours
Credit pull, lender packet, utility interconnection, permit, inspection. The homeowner signs once.
- 04
One page, one number
The quote is a single page: system size, monthly payment, and what the lender still needs from you.
- 05
Nobody knocks
We do not run door crews. If someone is on your porch in an SD Solar shirt, it is because you called.
