Solar Lamp Posts and Pole Lights for HOAs: Decorative Community Lighting Without Trenching

Yes, an HOA can light its entrance, private roads, mail kiosks and common areas with solar lamp posts and never dig a trench. A commercial solar pole light is a self-contained fixture: a solar panel charges a battery during the day, and an LED head runs from that battery at night, switching on at dusk by itself. It mounts on a standard 3 inch round pole, so each light needs only a pole foundation, not a trench back to a power source. That takes the biggest costs out of community lighting: digging, conduit, wire, an electrician's time and a utility connection, plus the electricity bill for those lights afterward. This guide shows the board what trenching really costs, how much light each part of the community needs, which fixtures fit where, and the trade-offs to plan for.

Solar lamp post vs. commercial solar pole light

Search for "solar lamp post" and most results are lantern-style posts sold for a front yard, often with a planter base. They are pleasant accent lights for a garden bed. They are not built to light a community entrance or a private road. When you compare, look for three numbers on the product page:

• Rated lumens. This is how much light the head produces. Entrance and road fixtures should be rated in the thousands.
• Battery and panel size. Bigger panels and batteries carry the light through long winter nights and cloudy spells.
• Mounting height and pole size. Commercial heads mount on 10 to 12 foot poles and spread light over a much wider area than a 5 foot yard post.

Our lead fixture for communities is the 20W solar powered LED pole light: 3,000 lumens, a 12.5 W monocrystalline panel, a choice of 2700K warm white or 5000K bright white, and a fit for 2 3/8 to 3 inch poles. It is $499.99 each, or $449.99 each for 10 or more, as of October 2026.

It has three night modes, set with a button on the fixture:

• 30 percent all night, rising to full brightness when motion is detected.
• 100 percent for the first 5 hours, then 25 percent (full brightness on motion).
• 70 percent all night.

The product page rates it for up to 4 to 7 nights on a full charge and 5 to 6 hours of bright sun to recharge.

What trenching costs, and what solar takes off the table

The expensive part of wired community lighting is rarely the fixture. It is getting power to it. HomeAdvisor's 2026 cost guide puts professional trenching at $5 to $12 per linear foot including equipment and labor, and $13 to $40 per foot for extra-large or difficult digs. Trenching through finished landscaping, under sidewalks or across a paved road costs more again, and the board still has to pay for conduit, wire, an electrician, permits and a utility connection on top.

Worked example: entrance, mail kiosk and four road lights

• Six lights spread along about 600 feet of entrance drive and private road.
• Wired: 600 ft of trench x $5 to $12 per foot = $3,000 to $7,200 for digging alone. In rocky or hard ground at $13 to $40 per foot, the same run is $7,800 to $24,000.
• Solar: six 20W solar pole lights at $499.99 each = $2,999.94 for the fixtures, with no trench. Each light still needs a pole and a foundation, which a wired light needs too.

Trenching rates from HomeAdvisor's trenching cost guide (updated June 2026). Wire, conduit, labor, permits and utility charges for the wired option are not included, so the true gap is wider. Poles are quoted on request.

The electricity saving is real but smaller, and boards should hear the honest number. A wired 25 W LED fixture running 12 hours a night uses about 110 kWh a year. At the U.S. average commercial rate of 14.19 cents per kWh, that is about $16 a year per light, or about $93 a year for six. The big saving with solar is up front: no trench through the landscaping, no new meter, and no electrician on site.

25 W x 12 hours x 365 nights = 109.5 kWh a year. Rate: U.S. Energy Information Administration, Electric Power Monthly, Table 5.6.A, commercial sector, June 2026. Your utility's rate will differ.

How much light does each part of the community need?

There is no single legal light level for a private HOA, so borrow from public standards. The City of San Diego's Street Design Manual, which follows the Illuminating Engineering Society's roadway lighting practice (RP-8), sets pedestrian-scale lighting at an average of at least 0.4 foot-candles on residential sidewalks, 0.6 in mixed-use areas and 0.9 in commercial areas.

A foot-candle is one lumen per square foot. Not every lumen from a pole light lands on the ground you care about, so a simple planning assumption is that about half does. That gives a quick estimate:

Area lit (sq ft) = rated lumens x 0.5 / target foot-candles

So a 3,000 lumen pole light covers about 3,000 x 0.5 / 0.4 = 3,750 square feet at a residential 0.4 foot-candles, or about 1,670 square feet at a brighter 0.9 foot-candles.

Which light goes where

Planning estimates only: area = lumens x 0.5 / 0.4 foot-candles. Real coverage depends on mounting height, optics and surroundings. Specifications from our product pages, checked 14 October 2026.

Area math gives the minimum number of lights, not the spacing. On a private road, lights 150 feet apart give pools of light with darker gaps between them, which is how many communities light roads: at the entrance, intersections, curves and the mail kiosk. If the board wants continuous, even light along a road or path, place fixtures closer together and ask us for the fixture's photometric file before you finalize the plan.

For the clubhouse or amenity lot, our solar parking lot lighting guide sizes fixtures by lot size, and the parking lot signs guide covers the signs the lot needs.

Making it look like part of the neighborhood

Board members usually care as much about how the lights look by day as how they work at night. Three pieces dress up a solar pole:

• Black round aluminum poles. Our 10 ft and 12 ft aluminum 3 inch round poles come in matte or glossy black (quoted on request).
• A decorative base cover. The base cover for 3 inch poles hides the anchor bolts with a two-piece black powder-coated shroud ($299.99).
• A dual-head arm. The decorative dual-head arm bracket ($699.99) carries two fixtures on one pole for a formal entrance. The second light head is sold separately.

Color temperature matters too. Warm white (2700K on the 20W pole light, 3000K on the bollard) reads as residential and inviting, the way most neighborhood porch lights look. Bright white (5000K) looks crisper and suits parking, gates and security areas. Many communities use warm white at the entrance and along homes, and bright white at the amenity lot.

The trade-offs to plan for

• Sun exposure. Each panel needs open sky. Mature trees, tall buildings and the north side of structures cut charging. Pick pole locations with the panel in mind.
• Winter nights. Long nights and short days drain batteries faster. The dimming and motion modes exist for this; a light that runs at 30 percent and jumps to full on motion goes much further than one at 100 percent all night.
• Batteries are a wear item. The 20W pole light's page lists battery life at 3 to 5 years and the warranty at 1 year; the 15W bollard carries 2 years and the 30W post top 3 years. Budget for battery replacement in the reserve study.
• Light output per pole. A solar pole light is not a 150 W street light. It is right for entrances, kiosks, paths and pools of light along a road, not for floodlighting a large field.
