How to Install Lensun Solar Panels

Step-by-step installation guides for hood solar panels, flexible panels and portable systems — with real video tutorials from Lensun and independent creators.

Step 1 — Surface Preparation (5 min)

• Wash hood surface with isopropyl alcohol (IPA 70%+) — remove all wax and grease
• Let dry completely — 10 minutes minimum in warm weather
• Measure panel dimensions against hood and mark edges with masking tape
• Pro Tip: Use a clean microfiber cloth with IPA. Avoid paper towels — they leave lint that ruins adhesion.

Step 2 — Panel Placement (10 min)

• Dry-fit the panel (no adhesive) — confirm it lies flat with no gaps larger than 3mm
• Center the panel left-right using masking tape guidelines
• Ensure panel does not overhang hood edges — leave 15mm margin minimum
• Mark final position with masking tape corners before removing panel

Step 3 — Adhesive Mounting (15 min)

• Apply VHB tape strips to the back of the panel (included in kit)
• Peel backing halfway on each tape strip before positioning
• Align panel to masking tape marks and press firmly — start from center outward
• Apply pressure along full surface for 60 seconds minimum
• Allow 24-hour full cure before driving — 72 hours recommended
• Pro Tip: Ideal mounting temperature: 15°C–38°C. Below 10°C the adhesive will not bond properly.

Step 4 — Cable Routing (20 min)

• Route cable along hood crease to minimize visibility
• Use included cable clips or self-adhesive cable tie bases
• Pass cable through firewall using existing grommets (no drilling required)
• Leave 100mm of slack at hood-body junction for hinge movement
• Seal all cable entry points with self-amalgamating tape or silicone

Step 5 — MPPT Controller Wiring (30 min)

• Connect panel cable to MPPT controller PV input (check polarity first)
• Connect MPPT output to battery — positive first, negative second
• Set battery type on MPPT (AGM/LiFePO4/Gel) before first connect
• Add inline fuse between MPPT and battery (within 150mm of battery)
• Pro Tip: Never connect/disconnect battery while panel is in sunlight — disconnect panel first.

Step 6 — System Test (10 min)

• Check MPPT display shows panel wattage in direct sunlight
• Verify battery charging current on controller display
• Perform a hood flex test — open and close hood 10 times, check cable slack
• Register your warranty at lensunsolar.com
• Expected output: In full sun, a 100W panel should show 70–90W on MPPT display.
