NABCEP (North American Board of Certified Energy Practitioners) certification is the solar industry’s principal competency credential, earned through exams covering system design, electrical code, and safety. NEDES holds this certification among many others. We applied it to residential and commercial installations across the Mid-Atlantic to design each system around the net metering rules and SREC market specific to its state.

Here’s What We Install

Solar Services NEDES Handles In-House

A completed Virginia Solar Panel Installation on a two-story home with a garage, powering a sustainable suburban lifestyle.

Residential Solar Panel Installation

Systems are sized to a home's roof orientation, shading pattern, and utility rate, then interconnected to the local net metering program so exported power earns a credit at the full retail electricity rate in Virginia and Pennsylvania.

Commercial Solar Installation

Commercial arrays can access the Section 48E federal investment tax credit at 30% through 2027 when structured under third-party ownership. NEDES designs commercial-scale systems with production monitoring and scheduled maintenance.

System Add-On Panels & Inverter Installation

Adding panels or upgrading an inverter raises system output without a full replacement. NEDES checks the existing equipment's warranty terms and interconnection limit before integrating new hardware, so coverage stays intact.

EV Charger Installation

Per NEC Article 625, a Level 2 charger requires a dedicated branch circuit sized at 125% of its continuous load. NEDES's 60-amp hardwired circuits support a 48-amp draw, delivering a sustained 11.5kW charging stream on 240V THHN wiring.

Solar Panel Unmount, Remount & Roof Repair

Before a roof replacement, NEDES unmounts the array, then remounts it once repairs finish, preserving the original racking warranty and re-sealing every penetration point to manufacturer spec.

Lightning Rod & Grounding Installation

NFPA 780 added a dedicated chapter covering solar array grounding and bonding in its 2017 edition. NEDES installs lightning rod and grounding hardware on every system to that chapter's strike-termination and bonding requirements.

Portfolio With Proof

Panels, Critter Guards & Battery Equipment We’ve Installed

A critter guard is a PVC-coated wire mesh barrier that keeps squirrels and birds from nesting beneath rooftop panels. Rodents chew exposed DC wiring insulation, and a single affected wiring run typically costs $200-$500 to repair; a properly installed guard prevents most of that damage before it happens.

Three Reasons Homeowners Pick US Over Other Mid-Atlantic Installer

NEDES pairs certified installation crews with manufacturer- and insurance-backed protection. Three factual, verifiable reasons homeowners across Maryland, Pennsylvania, Virginia, Delaware, and DC choose NEDES:

1. A $1,000 Referral Credit

When a current NEDES customer refers you, you receive $1,000 off your completed installation. Comparable Mid-Atlantic installers typically offer a $500 referral credit, half of what NEDES pays out.

2. Insurance-Backed Lifetime Warranty

Align Solar Protection is a third-party, insurance-backed warranty administrator, not a manufacturer’s warranty. Coverage is backed by an AM Best A+-rated insurance carrier and includes panels, inverters, racking, and roof-penetration resealing, with no-deductible claims for as long as you own your home, well beyond the 10- to 25-year terms most manufacturer warranties offer.

3. Tesla Powerwall Certified Installer

The Tesla Powerwall 3 stores 13.5 kWh and delivers 11.5 kW of continuous output, roughly double the 5-7 kW ceiling of most competing home batteries. As a certified installer, NEDES configures Powerwall systems for time-of-use optimization and whole-home outage backup, sized to your essential circuits.

How Much Power Does A Tesla Powerwall Actually Store?

A single Tesla Powerwall 3 holds 13.5 kWh of usable capacity at 97.5% round-trip efficiency, enough to cover a typical Mid-Atlantic household’s overnight and evening use. Its 11.5 kW continuous output can run central air conditioning and other high-draw appliances simultaneously during an outage, without load shedding.

As a Tesla-certified installer, NEDES configures every Powerwall for time-of-use optimization, shifting stored solar power to the hours when utility rates peak, with outage protection sized to your home’s essential circuits during your free consultation.

How Fast Is A NEDES EV Charger Installation?

NEDES's hardwired 60-amp circuits deliver a constant 11.5kW charging stream, roughly 25-35 miles of range per hour, on dedicated NEC 625-compliant, thermal-safe wiring that avoids the nuisance tripping common on shared outlets. Plug-in installs use a NEMA 14-50 outlet instead, so you can move the charger or swap vehicles without losing Level 2 speed.

What You Get As A NEDES Customer, Beyond Installation Day

Every NEDES customer qualifies for the $1,000 Referral Program and lifetime, no-deductible Align Solar Protection coverage, plus 24/7 support. These are just three benefits that continue for as long as you own your system, not just through the installation date.

FAQs

Frequently Asked Questions

How Long Does Solar Panel Installation Take In 2026?

Most NEDES residential systems install in 1-5 days on site. The full process, from consultation to activation, takes 1-3 months, depending on utility interconnection review and local permitting timelines.

Will Solar Panels Still Produce Power On Cloudy Days?

Solar panels continue generating electricity on cloudy days, typically at 10-25% of clear-day output. Panels convert diffused daylight, not direct sunlight alone, into electricity, which is why production drops but doesn’t stop.

How Much Output Do Solar Panels Lose Over 25 Years?

Modern Tier 1 panels degrade at roughly 0.5% per year, per NREL fleet data, retaining about 87-90% of original output at year 25. Panels keep producing well past the 25-year warranty mark; they simply generate a little less each year.

How Much Can I Save With Net Metering In Virginia Or Pennsylvania?

Net metering credits exported solar power at the full retail electricity rate in both Virginia (Dominion Energy, Appalachian Power) and Pennsylvania (PUC-protected, all investor-owned utilities). A correctly sized system can offset most or all of a monthly electric bill, depending on household usage and roof orientation.

Are There Still Solar Incentives In Virginia, Pennsylvania, Maryland, Delaware & DC In 2026?

The 30% federal residential tax credit (Section 25D) expired December 31, 2025 under the One Big Beautiful Bill Act, so cash and loan purchases no longer receive it. Virginia and Pennsylvania homeowners can still access full retail net metering, sellable SRECs (currently trading near $25-$45 per credit in Pennsylvania and $27-$33 in Virginia) and Virginia’s local property tax exemption on solar equipment. Commercial and third-party-owned (lease/PPA) systems can still access the 30% federal Section 48E credit through 2027.
