📡 The 16ft Detachable Panel — Why It Changes Everything

🌟 The Feature Barn & Shed Owners Have Been Waiting For

Most solar flood lights lock the panel directly to the light head. If your barn wall faces north, your workshop is shaded, or you need the light inside the stall — you're forced to choose between coverage and charging. Not here.

The Solaraluma Flex 1664 connects the panel to the light with a 16.4-foot (5-meter) weatherproof DC cable. Mount the panel in full sun on the south face of your barn roof. Run the cable around the corner or through a small drilled hole. Mount the light exactly where you need it — inside the barn, on a shaded north wall, above the workshop door, or in a horse stall. No compromise. That's a fundamental design difference that makes this light work where others don't.

⚠️ Before You Start — Read This First

⚡ Safety & Warranty — Important

Never connect this unit to 220V AC or any household current. It will permanently damage the light and may cause electric shock or fire.
Mount only on solid, permanent surfaces — walls, timber posts, steel poles. The bracket must not flex or shift in wind.
Do not open or disassemble the light housing or solar panel frame (unless replacing the battery yourself). Doing so voids the 2-year warranty immediately.
Clean the solar panel regularly. Dust, pollen, and bird droppings reduce charging efficiency by up to 30% — especially in dry ranch and desert environments.

☀️ First Use — Full Pre-Charge Required

The LiFePO4 battery ships at a partial charge for transport safety. Before the first night of use, place the panel in direct sunlight for one full day (6–8 hours). This pre-charges the 24Ah battery to full capacity and guarantees all-night brightness from night one. Skipping this step is the most common reason the light goes out early on its first night.

What You'll Need (Not in the Box)

Drill with appropriate bit for your surface (masonry, wood, or metal)
Phillips head screwdriver
Pencil or marker (for marking hole positions)
Ladder suited for 10–16ft working height
Tape measure or level (optional — helps with alignment)

🔧 Step-by-Step Installation

Follow these steps in order. Most property owners finish in under 20 minutes. You'll need your drill and the included hardware — nothing else.

Unbox and Identify All 6 Parts

Lay everything out on a flat surface. Confirm you have: solar panel, flood light head, DC cable, wall bracket, hardware pack, and remote. Check that the DC cable connector matches the port on the flood light — the connectors are keyed and only fit one way. Do not force the connection.

Connect the DC Cable (Panel → Flood Light)

Align the waterproof connector from the solar panel cable to the port on the flood light. Match the flat orientation guides before pushing in, then twist clockwise to lock. A secure connection shows no gap at the collar. This is the only "wiring" in the entire install — and it's completely tool-free.

💡 Quick Test Before Mounting: Connect the cable, then take the panel outside into sunlight. The charging indicator light on the unit will flash — this confirms the connection is solid and power is flowing correctly.

Choose Your Mounting Locations

Flood Light Location: Select the wall, barn door frame, post, or interior surface where you need light coverage. Recommended mounting height: 10–16 feet (3–5 meters). Higher = wider coverage radius. Lower = more concentrated brightness on a smaller zone.

Solar Panel Location: The panel needs unobstructed direct sunlight — no overhangs, tree branches, or structures casting shade. South-facing at a 35° tilt is optimal for most U.S. locations. You have 16.4 feet of cable to work with — the panel doesn't need to be on the same wall or even the same side of the building.

💡 Barn Tip: Run the DC cable through a ½-inch hole drilled through the barn wall — panel on the south exterior face, flood light inside the stall. This is the most popular installation among Solaraluma barn owners.

Mark and Drill Mounting Holes

Hold the mounting bracket against the wall at your target height. Use the bracket holes as a template and mark your drill points with a pencil. Drill tip by surface type:

Concrete or masonry: Use a masonry bit and the included anchors
Wood post or timber: Drive screws directly — no anchor needed
Metal surface: Pre-drill with a metal bit, then use the included screws

Attach the Mounting Bracket

Drive the included screws through the bracket into your drilled holes. Once mounted, pull firmly — it should not flex, shift, or wiggle at all. This bracket carries the flood light through wind, rain, and ice loads. Pre-adjust the bracket angle before attaching the light so it points toward your target coverage zone.

Hang the Flood Light Head

Slide the flood light head onto the mounted bracket and secure with the included bolts. Aim the beam toward your coverage area — a 30–45° downward tilt from vertical works well for most driveway and gate applications. Tighten all bolts fully. The IP66 housing handles any weather condition once locked.

Mount and Angle the Solar Panel

Mount the solar panel bracket at your sun-facing location. Important: the solar panel must be positioned above or at the same height as the flood light — this prevents water from pooling at the cable connection point. Route the DC cable along the wall edge using cable clips for a clean, wind-resistant run. Refer to the Panel Angle Guide in Part 2 for optimal tilt by U.S. region.

First-Time Activation — Press AUTO

With the panel connected and in sunlight, point the remote at the flood light and press the AUTO button. This activates optical/dusk-to-dawn mode — the recommended setting for daily use. The light will turn on automatically every evening at dusk and off at sunrise, every single night, with no further action needed.

✅ Confirm it's working: Cover the light sensor (the small round lens on the unit) with your hand for 3 seconds. If the flood light activates, the sensor and DC connection are both working correctly. Uncover it and it returns to standby in daylight.

☀️ Solar Panel Placement & Angle Guide

Panel angle is the #1 factor that determines all-night runtime. Getting this wrong costs you 25–50% of daily charge — meaning your light may dim or go out before dawn.

→ Always Face South in the Continental U.S.

✅

35° Tilt — South

100% charging efficiency. Ideal for most U.S. latitudes. Start here.

⚠️

10° Tilt — South

~75% efficiency. Flat-roof mounts lose significant output, especially in winter.

❌

60° Tilt — South

~50% efficiency. Too steep — especially in summer when the sun tracks high.

U.S. Regional Adjustment Tips:
• Northern Tier (MT, WY, ND, MN, ID): Increase tilt to 40–45° from December through February for better winter sun angle
• Southern Tier (TX, AZ, FL, NM): 25–30° works well year-round — sun stays high
• Pacific Northwest (OR, WA): Use 5H or 8H timer mode during Nov–Feb to stretch battery reserve through low-sun stretches
• All regions: Avoid any partial shading — even 20% shade on the panel can cut output by more than 50%

🧹 Maintenance & Long-Term Care

Clean the solar panel every 4–6 weeks with a damp cloth. In dry, dusty ranch and farm environments, a coating of dust and pollen can reduce daily charge by up to 30% — directly shortening your overnight runtime.
Inspect the DC cable connection twice a year (spring and fall) to confirm it's fully seated and sealed. Check after any severe storm or high-wind event. A partially loose connector is the most common cause of unexplained dim performance.
Adjust panel tilt angle seasonally in northern states. Re-tilting your panel to 40–45° from December through February can recover meaningful charge capacity as the sun drops lower on the horizon. Takes five minutes with a screwdriver.
Battery replacement is a DIY job when the time comes — typically 8–12 years from installation. The front-frame access panel opens without special tools. Swap the 24Ah LiFePO4 cell and you're back to full original performance. No need to replace the whole unit.
If the light starts dimming earlier in the night: clean the panel first, then check the DC cable connection. If the issue persists, contact our Wyoming team at info@solaraluma.com — we respond within 1 business day.

❓ Installation FAQ

Q Can I mount the flood light inside my barn and run the cable through the wall to the panel outside?

Yes — and this is exactly the installation this light was designed for. The 16.4ft DC cable passes cleanly through a ½-inch hole drilled in a barn wall, letting the flood light illuminate the stall interior while the panel faces south on the exterior wall or roof. This is the most common installation among Solaraluma barn and horse arena owners. The waterproof connector holds up to moisture and temperature swings even if a section of the cable is exposed at the wall penetration.

Q My available wall faces north. Can I still use this light?

Yes — mount the flood light on the north-facing wall where you need coverage, but route the DC cable around the building corner to position the panel on an east, west, or south-facing surface. The 16.4ft cable is long enough to clear most barn eave lines and corners. Do not mount the panel on a north-facing surface — in the continental U.S., a north-facing panel charges at less than 20% of its rated capacity and will not support reliable all-night operation.

Q The light didn't turn on the first night. What should I check?

Nine times out of ten, this is a pre-charge issue. The LiFePO4 battery ships at a partial charge for transport safety — place the panel in direct sunlight for a full day (6–8 hours) before first use. If that's already done, check in this order: (1) confirm the DC cable connector is fully locked — push in and twist until it clicks; (2) press the AUTO button on the remote pointed directly at the light; (3) test the sensor by briefly covering it with your hand — if the light activates, the unit is working correctly. If none of these resolve the issue, email info@solaraluma.com and we'll respond within 1 business day.

Q How many lights do I need for a full barn interior (40 × 60 ft)?

At 10ft mounting height, one Solaraluma Flex 1664 covers approximately 800 square feet at practical task-lighting brightness. For a 40 × 60 ft (2,400 sq ft) barn, 3 units positioned at the upper wall corners and center ridge give full, even coverage with no dark corners. For a single use zone — feed room, wash stall, or tack room — one unit at 8–10ft is sufficient. Using 6500K cool white mode in a barn interior closely matches natural midday light, making nighttime chore visibility noticeably easier.

Q Will this hold up through Wyoming or Montana winters?

Yes. The LiFePO4 battery maintains stable output down to -4°F (-20°C), covering the full overnight low range of even the coldest northern U.S. states. Standard lithium-ion batteries — used in most budget solar flood lights — lose 30–50% capacity below freezing, which is why cheap solar lights fail in January even though they "worked" all summer. The IP66 housing resists sleet, snow, and high-pressure ice storms. During December and January, use the 8H timer mode and half-brightness setting to stretch battery reserve through the darkest weeks without losing overnight coverage.
