Commercial parking lots require consistent illumination meeting IES RP-8 standards, with uniformity ratios below 4:1 and minimum maintained footcandles between 1 and 3 across every bay. Traditional grid-tied parking lot lighting forces trenching through asphalt, utility service drops, electrical permits, and decades of monthly energy billing. A typical 20-fixture retrofit runs 6 to 12 weeks and $80,000 to $150,000 in trenching and electrical work before a single fixture mounts.
SolarPath Sun Solutions eliminates every trenching step. Each fixture runs on a lithium iron phosphate (LiFePO4) battery, MPPT charge controller, and high-efficiency photovoltaic (PV) panel mounted on the pole. A 20-fixture parking lot installs in 5 to 10 crew days at 40 to 60 percent of the total installed cost of a grid-tied equivalent. IP66 ingress protection, -40 F to 140 F operating range, and DLC listing make SolarPath fixtures rebate-eligible and procurement-ready for retail, healthcare, institutional, and municipal parking projects.
Browse our all-in-two street lights, all-in-one fixtures, and canopy lights for parking lot deployments.
SolarPath all-in-two fixtures are the flagship specification for mid-to-large commercial parking lots. Mounted at 25 to 30 foot pole heights, they deliver 6,000 to 12,000 lumens per fixture with Type III distribution and 2 to 3 footcandles average maintained.
All-in-one fixtures suit small lots, residential community parking, and quick retrofit projects at 15 to 25 foot pole heights with 3,000 to 6,000 lumen output. Solar canopy lights cover gas station islands, retail drive-through lanes, and parking deck retrofits with low-profile under-canopy mounting.

A regional retail chain needed to retrofit 48 parking bays across three store locations without closing any lot for more than one night per site. Existing high-pressure sodium fixtures drew 2.4 kWh per fixture-night, and the conduit replacement required for a grid-tied LED retrofit would have demanded three weeks of parking closure per store plus an electrical permit and utility coordination window.
SolarPath all-in-two fixtures at 25-foot pole heights delivered 8,000 lumens per fixture with Type III distribution and 2.5 footcandles average maintained. Installation completed in two crew days per store with no trenching, no utility coordination, and no fixture downtime during daylight hours. Monthly energy cost dropped from $1,440 to zero across all 48 fixtures, and the five-year warranty covers panel, battery, controller, and LED array for every unit on the project.
Every SolarPath parking lot project is photometrically engineered to the site. Our team delivers a stamped IES RP-8 compliant photometric study, an autonomy calculation tied to site peak sun hours, and a commissioning checklist our field team completes on handover.
Every project ships with a stamped photometric study confirming lux targets, uniformity ratios, and fixture placement before procurement.
3000K and 4000K CCT with full-cutoff optics meet International Dark-Sky Association ordinances and county regulations.
Standard coverage on the photovoltaic panel, LiFePO4 battery, MPPT charge controller, and LED array across every SolarPath fixture.
Off-grid parking lot lighting reshapes commercial project economics. Eliminating trenching means construction proceeds without waiting for underground utility coordination. Eliminating utility billing means no monthly energy cost, no demand charges, and no exposure to rate increases over the fixture lifetime. Low maintenance requirements mean service visits occur on a multi-year cadence rather than monthly or quarterly. DLC and UL listings open federal, state, municipal, and corporate procurement contracts with rebate eligibility in most states. Quick installation finishes a 10-fixture parking lot in under one week including photometric commissioning and handover documentation.

IES RP-20 and RP-8 specify 1 to 3 footcandles average maintained with uniformity ratios below 4:1. Retail and institutional lots target the higher end. Employee and long-stay lots target the lower end. SolarPath photometric studies confirm targets per site.
20 to 30 feet is the standard range. Small lots and low-speed areas use 20 feet. Standard commercial lots use 25 feet. Large lots and higher-mounting-height codes use 30 feet. Pole height depends on target lux, fixture distribution type, and spacing.
5 to 10 crew days for a 20-fixture lot including foundation pour, pole erection, fixture mounting, and photometric commissioning. No trenching, no utility coordination, no electrical permits in most jurisdictions.
A typical 100-space retail parking lot uses 8 to 12 fixtures at 25-foot pole heights. A 200-space lot uses 15 to 20 fixtures. SolarPath photometric studies calculate the exact fixture count and placement based on your site dimensions and target lux.
Yes. Every SolarPath parking lot fixture ships DLC listed and UL listed, unlocking utility rebate eligibility and meeting federal, state, and municipal procurement specifications nationwide.
Four nights standard. Sites in the Sun Belt may ship with three-night autonomy. Northern and Pacific Northwest sites ship with five to seven-night autonomy to cover extended overcast winter conditions.
Yes. Programmable dimming, PIR motion sensors, and scheduled shutoffs meet California Title 24 Part 6 outdoor lighting controls. 3000K CCT with full-cutoff optics meets IDA dark-sky ordinances in Arizona, Colorado, Florida, and other jurisdictions.
