Solar Installer Hoodie and Sweatshirt Guide: Cold-Weather Crew Apparel

Solar installer hoodies and sweatshirts are the cold-weather workhorse. A 6 AM roof start in October hits 38 degrees with wind. The same installer is sweating by 10 AM as the sun warms the roof. The hoodie or sweatshirt has to handle both ends of that swing without becoming a soaked, heavy weight by lunch. Here is the cold-weather apparel guide for solar crews, including the fabric and fit specs that actually work in the field.

Cold-Weather Apparel Spec for Roof Work

The cold-weather garment for a solar installer has to handle a specific use case: insulating layer at the start of the shift, removable mid-shift as the sun warms the roof, and quick-drying if it gets sweat-soaked. The fabric spec:

• Heavyweight cotton-poly blend (50/50, 60/40, or 80/20). Cotton for comfort, poly for sweat-wicking and faster drying. Pure cotton holds sweat and gets heavy.
• Performance fleece (100% polyester). Lighter weight, faster drying, less insulation than cotton-poly. Better for shoulder seasons (October, March, April).
• Heavy fleece (300-400 GSM weight). True winter insulation. Used over a long-sleeve base layer in 25-45 degree starts.

The wrong choice is a pure 100% cotton hoodie. Cotton soaks up sweat, dries slowly, and chills the installer when the temperature drops. The cotton hoodie has its place (off-shift, casual wear, customer-facing merch) but not as the on-roof workhorse.

Hoodie vs Quarter-Zip vs Crewneck: Which One Wins

Three garment styles compete for the cold-weather slot. The right choice depends on the role and the working conditions.

Pullover hoodie.

• Pros: hood for added head and neck warmth, kangaroo pocket, casual aesthetic.
• Cons: hood can get caught in harness or equipment, must be pulled off over the head when overheating.
• Best for: apprentices and installers who work in less hood-restricted environments.

Quarter-zip pullover.

• Pros: easy temperature regulation via zipping down, professional appearance, no hood to catch.
• Cons: no hood, slightly less warm at the neck.
• Best for: crew leads, customer-facing roles, and any installer who values quick temperature adjustment without removing the garment.

Crewneck sweatshirt.

• Pros: clean appearance, low harness-rub, doubles as casual wear off-shift.
• Cons: no hood, no zipper to vent.
• Best for: shoulder-season wear, customer-facing meetings, and as a layer under a hard shell.

Most crews issue 1 hoodie and 1 quarter-zip per installer per year. The hoodie handles deep cold; the quarter-zip handles the daily temperature variation.

The Cold-Weather Layering System

A single hoodie is not the answer to a 38-degree morning. A layering system is. The four-layer setup for roof work in cold weather:

1. Base layer: Performance long-sleeve tee. UPF rated, moisture-wicking, fitted.
2. Insulation layer: Hoodie, crewneck, or quarter-zip. Heavyweight cotton-poly or performance fleece.
3. Wind layer: Optional hard shell or wind vest for windy roof starts. Removed once the day warms.
4. Hi-vis layer: Class 2 hi-vis vest worn over the insulation layer when required.

The installer starts the shift in all four layers, peels off the wind layer by 9 AM, peels off the insulation layer by 11 AM, and works in the base layer plus hi-vis through the afternoon. The reverse sequence applies as the temperature drops at end of day.

Cold-Weather Kit Cost Per Installer

Per-installer cold-weather kit cost:

Item	Cost
Branded heavyweight hoodie	$36.88
Branded quarter-zip pullover	$34.88
Branded performance fleece pullover (optional)	$36.88
Hi-vis hoodie (commercial work)	$48
Total cold-weather kit per installer	$72-$157

Most solar companies issue the hoodie + quarter-zip combo ($72) and add the hi-vis hoodie ($48) for commercial-focused installers. For the broader uniform program math, see our solar crew uniform program guide.

Hoodies as the Highest-Margin Customer Merch Item

The branded company hoodie is also the highest-margin item in a solar company's customer-facing merch shop. The same garment that crews wear on the roof, customers buy at retail markup.

The economics:

• Base cost: $36.88 (heavyweight cotton hoodie with logo).
• Customer retail: $58-$72 in green-leaning markets where customers are willing to pay for branded apparel.
• Profit per hoodie sold: $21-$35.

A solar company that sells 60 hoodies per year through its merch shop earns $1,260-$2,100 in profit from this single SKU. Often the bestselling item in the customer-facing catalog. For more on the merch-shop side, see our how to start a solar company merch shop.

Frequently Asked Questions

What fabric is best for a solar installer hoodie?

Heavyweight cotton-poly blend (50/50 or 60/40 cotton-poly) for cold weather, or performance fleece (100% polyester) for milder temperatures. Pure cotton hoodies hold sweat and chill the installer when temperatures drop.

Should solar installers wear quarter-zips instead of hoodies?

Yes, often. The quarter-zip allows mid-shift temperature regulation via zipping down without removing the garment. Crew leads and customer-facing roles especially prefer the quarter-zip for the professional appearance.

How many hoodies and sweatshirts does an installer need per year?

1 hoodie and 1 quarter-zip is the standard kit. Optional add: a performance fleece pullover for shoulder seasons (October, March). Hi-vis hoodie added if the installer works commercial sites.

Are branded hoodies a good item to sell to customers?

Yes. Branded hoodies are typically the bestselling item in a solar company merch shop. Customer retail $58-$72 with $21-$35 profit per item. The same garment serves as crew uniform and customer merch.
