Most EV charger installation businesses face a critical choice: sell chargers themselves, offer installation labor, or do both. Getting this mix right directly impacts your margins, customer acquisition costs, and how much you can scale without hiring a full warehouse team.
The Product-Only Approach: Lower Commitment, Thin Margins
Selling chargers as standalone products means you handle procurement, inventory, shipping, and customer support—but customers install them themselves or hire someone else. You're competing on price and selection, not expertise.
Realistic margins run 15–25% on Level 2 home chargers ($500–$2,500 retail) and 10–18% on DC fast chargers (which can exceed $50,000). You'll need storage space, capital tied up in stock, and logistics infrastructure. Payment processing and returns become operational headaches, especially for bulky equipment.
This works if you have existing traffic (website, local reputation, contractor relationships) and can move inventory fast. Otherwise, you're eating carrying costs while competing against Amazon and specialty distributors.
Installation Services: Where Real Revenue Lives
Installation is where the money is. You charge labor ($1,500–$5,000 for residential Level 2, $3,000–$15,000+ for commercial setups), material markup (20–40%), and you control the customer relationship from start to finish.
Typical job workflow:
- Site assessment and electrical load calculations
- Permitting and inspection coordination (2–8 weeks)
- Trenching, conduit runs, electrical panel upgrades
- Charger mounting and final testing
- Customer handoff and warranty support
This model scales with your team's capacity. A two-person crew can handle 3–5 residential installs monthly; add electricians and you multiply revenue without massive capital outlay. Margins stay fat because customers value done-for-you solutions, not just the hardware.
The Hybrid Model: Products + Services
Most successful installation businesses eventually blend both. You sell chargers to customers who want them installed and to other contractors who handle the labor themselves. You become a trusted supplier and installer simultaneously.
How to structure it:
- Retail your chargers to DIY customers (lower support burden, quick shipping)
- Offer installation packages bundling charger + labor + permits at premium pricing
- Wholesale or distribute to other contractors in your area (5–15% margin, but volume play)
- Bundle financing options (many customers want payment plans for $8,000+ projects)
The key is separating operations. Your retail storefront (physical or digital) handles product orders; your installation crew focuses on labor-only and bundled service jobs. You can list both products and services on platforms like Mercoly to reach homeowners and contractors searching for EV charger installation in your area, capturing leads across both segments.
Critical Decision: Inventory vs. Fulfillment
If you stock chargers, your cash gets locked in inventory. A 50-unit Level 2 charger stockpile at $1,200 wholesale = $60,000 sitting in a warehouse. Turnover matters—if you move 2 units weekly, that's acceptable; if it's 1 per month, you're underwater.
Better alternative for most installers:
- Partner with one or two reputable suppliers (Tesla, Chargepoint, Eaton, JuiceBox)
- Drop-ship to customers or stock only best-sellers
- Keep your capital focused on tools, truck, crew training, and permits
- Maintain 10–15% of your annual service revenue in charger inventory for quick bundled installs
Scaling Toward Product + Service Revenue
Start with what you do best: installations. Build a referral network and reputation. As demand grows and customers ask "Can you just sell me the charger?"—that's when you test retail.
Launch with three popular Level 2 models and one commercial option. Track sell-through monthly. If you're moving 5+ units monthly, expand. If it's 1–2, stick to service bundles and let customers source their own equipment.
Pay attention to seasonal demand. EV incentives, tax credits, and new home construction cycles create spikes. A June–September surge might justify staffing up; plan accordingly rather than reactively.
Frequently Asked Questions
Q: What permits and inspections do I need for EV charger installation? Permitting varies by jurisdiction—some require electrical permits only, others add separate EV charger permits. Typical lead time is 2–8 weeks. Always check your local building department and utility company requirements before quoting jobs.
Q: How much should I charge for installation labor on a Level 2 charger? Residential Level 2 installation labor ranges $1,500–$5,000 depending on panel distance, trenching needs, and local electrician rates. Panel upgrades and concrete work add $1,000–$3,000+. Charge hourly labor (usually $85–$150/hour for licensed electricians) plus material markup rather than flat-rate if the job scope is unclear.
Q: Should I finance charger purchases for customers? Offering financing (via Affirm, Sunlight, or local lenders) increases your close rate by 30–40% since many customers see $3,000–$8,000 charger + installation as a major expense. You get paid upfront and push collection risk to the lender—smart move as you scale.
