What Moves a Solar Quote Off $1.85 Per Watt in Tampa Bay
Fused Solar and Roofing prices new residential solar at a flat $1.85 per watt installed for a single-story home with a standard pitch and a shingle roof, so a 20-panel, 8.8 kW system is $16,280 and a 26-panel, 11.44 kW system is $21,164. Most Tampa Bay homes land at or near that number. Some do not, and the reasons are specific, visible on the proposal as their own lines, and worth understanding before comparing quotes, because a competitor's lower per-watt number that leaves them out grows after the site visit. Fused Solar and Roofing is a licensed roofing (CCC1331058), electrical (EC13014750), and building contractor (CBC1252064), all three in-house.
1. What the base price includes
Design and engineering, the permit, JA Solar 440W bifacial panels, the inverter chosen for the roof, K2 Systems hurricane-rated flashed mounting, the wiring and conduit, the electrical tie-in at the service panel, the inspections, and the utility interconnection paperwork. It includes Fused's 10-year workmanship warranty and its written 25-year no-leak guarantee on every roof penetration, under its own roofing license. Fused Solar and Roofing is a licensed roofing (CCC1331058), electrical (EC13014750), and building contractor (CBC1252064), all three in-house.
It does not include anything the roof, the house, or the homeowner's choices add, and those are the lines below.
🔑 Key Takeaway: $1.85 per watt is the whole installed system on a straightforward roof. Anything above it should be a named line on the proposal with a reason.
2. Two-story homes
A two-story roof means taller ladders or a lift, more fall protection, more time carrying modules and rails up, and slower work at height. Fused prices that as a two-story adder shown on its own line. Wesley Chapel, Riverview, FishHawk, Trinity, and Lakewood Ranch are mostly two-story; Largo, Pinellas Park, Brandon, and Town 'n' Country are mostly not, which is one reason systems in those towns land closer to the base rate.
The adder covers the access and the time, not a different system. The panels, the inverter, the mounts, and the warranties are the same on a two-story home as on a ranch; what the homeowner is paying for is the crew's day being longer and the setup being safer.
3. Steep pitch
A roof pitch above about 6/12 needs full fall protection rigging and slows every step of the install. Fused prices it as a steep-pitch adder, separate from the two-story line, because a steep single-story roof and a shallow two-story roof are different jobs. A homeowner with a two-story, 8/12 hip roof sees both adders; the proposal states the figure, and on a 26-panel system the two together are a few thousand dollars.
💡 Pro Tip: Ask any solar quote whether it already includes the two-story and steep-pitch work. A per-watt number that leaves them out is not comparable to one that has them in.
4. Tile and metal roofs
Tile roofs take tile-specific mounts and flashing, and the installer has to lift and cut tile around each attachment and reset it, which is slower and needs a crew that knows tile. Metal roofs vary: standing-seam metal takes clamp-on mounts with no penetrations and installs quickly; exposed-fastener metal needs a different mount and more care. Fused prices tile and metal as their own line based on the roof type the survey finds. A tile roof whose underlayment is near the end of its life is a different conversation, about doing the roof and the solar together.
On a tile roof whose underlayment still has life, the solar goes on with tile mounts and the tile is reset around them; on one whose underlayment is near the end, Fused will say the roof should be done first or with the solar, because putting a new array on failing underlayment means lifting the tile and the array again in a few years.
5. Panel and inverter choices
The base price is for JA Solar 440W bifacial panels, which Fused chose for their performance in Tampa Bay heat. A homeowner who wants REC panels, which carry a labor-inclusive warranty through Fused's REC ProTrust certification, pays the difference as a panel upgrade line. The inverter is chosen for the roof rather than sold as an upgrade: a single open south plane does well with a string inverter, and a multi-plane or partly shaded roof does better with microinverters or optimizers, and Fused picks the right one within the base price. Fused is certified with Enphase, SolarEdge, Tesla, Generac, Fronius, and SMA.
6. The electrical panel
A solar system connects at the main service panel through a backfeed breaker, and the panel has to have the physical room and the rating for it. A home with a 100-amp panel, a Federal Pacific or Zinsco panel, or a panel already full of breakers for a pool, a second air handler, and an EV charger may need a panel replacement or a load-side tap before the solar can connect. Fused does that work under its own electrical license and prices it as its own line, and the homeowner should know going in. It is the most common surprise on 1960s and 1970s block homes in Pinellas and west Hillsborough.
⚠️ Warning: A quote that does not mention the electrical panel on a home over forty years old has not looked at it. Ask what panel the house has and whether the quote covers a change.
7. Batteries and ground mounts
Battery storage is quoted separately from the array. A Tesla Powerwall 3 adds $12,500 installed; FranklinWH is quoted by configuration. Batteries are sized for backup rather than for bill savings, and a home that wants the refrigerator, a bedroom circuit, and the internet through an outage is usually a one-battery home. A ground-mounted array, which Fused installs on acreage lots in Ruskin, Lutz, Land O' Lakes, Parrish, and Plant City, is priced on its own because the racking, the trenching, and the permit are different from a roof mount.
8. What should never move the price
The brand of shingle. The age of the house by itself. The size of the family. The salesperson's quota at the end of the month. A homeowner who hears a per-watt price that changes without a named reason is being sold, not quoted. Fused's proposal shows the base system at $1.85 per watt and each adder on its own line with its reason, and the homeowner can see exactly what the roof shape, the panel choice, the electrical, and the battery are costing. The system is sized from twelve months of utility bills, not from the roof's capacity, and the proposal says what it will produce.

🔑 Key Takeaway: Base price, named adders, no mystery. If a quote cannot tell you why it is above $1.85 per watt line by line, it is not a quote you can compare.
