Don’t buy solar at sticker price.

A solar quote is a starting offer, not a price tag. Send us your written quotes — we negotiate them down, vet the installer’s license and track record, decode the financing, and review the contract before you sign. If we can’t beat your best quote by $500, you get your fee back.

Why it works

Solar companies negotiate for a living. Now you have someone who does too.

Most homeowners sign the first quote they’re handed. The gap between the highest and lowest quote for the same system can be thousands of dollars — and the financing can hide thousands more.

$3.36/W

Average U.S. residential solar cost, Q2 2026 (SEIA / Wood Mackenzie, reported by pv magazine). Know your benchmark before you talk price.

10–30%

Typical hidden “dealer fee” baked into solar loans, reported by the CFPB — sometimes over 50%. We find yours.

$500

Our guarantee: beat your best written quote by $500 on a like-for-like system, or your fee back. Conditions apply.

What we do

Five services. One flat fee. Zero commission.

Quote negotiation

We take your written quotes to installers and negotiate the price down — like-for-like equipment, real numbers, no theater.

Installer vetting

License, insurance, and review history checked before you sign — because solar companies fold, and warranties die with them.

Financing review

Cash vs. solar loan vs. lease vs. PPA — honest tradeoffs, dealer fees exposed, payment-shock clauses flagged.

Contract review

Escalation clauses, production guarantees, roof warranties, what happens if they disappear. Read before you sign.

Incentive guidance

What’s actually active in your ZIP — general information only, never tax advice. DSIRE is our starting point, not our answer.

Human backup

Questions anytime: call or text (404) 620-1781.

All Services, In Detail

Honest about the math

The 30% federal credit is gone. Anyone still subtracting it is lying to you.

The residential solar credit (Section 25D) ended for systems placed in service after December 31, 2025, under the One Big Beautiful Bill Act (summary; timeline). Some 2026 quotes still show it — that number is wrong, and it’s the first thing we check.

What that means for you: there is no federal cushion for overpaying anymore. The price you negotiate is the price you live with. That’s exactly why we exist.

One team, fourteen verticals

Sunline Solar Group is one of fourteen verticals in the THERXSIGNAL LLC family — meet them all.

Our Transparency Promise

We show our work.

What we verify

Every number we put in front of you comes from your paperwork or a public, hyperlinked source — SEIA, the CFPB, EnergySage, DSIRE, or the installer’s own documents. Nothing from vibes.

What we don’t do

No fake reviews. No invented savings figures. No “typical customer” stories. No selling your contact info. We are not installers and we take no commission from any installer, ever.

What we can’t promise

We can’t promise a specific dollar amount of savings — anyone who does that before seeing your quotes is guessing. Our guarantee is the refund: beat your best written quote by $500 or your fee back.

Who checks us

You do. Every negotiation summary shows the before-and-after numbers, the installer’s license lookup, and the contract flags — in writing, before you sign anything.
