Reliant Solar is a privately held Engineer · Procure · Construct contractor for commercial buildings, residential homes, construction scopes, and ground-up development across the tri-state and nationwide. Established 2023 in South Plainfield, NJ.
Established 2023 in South Plainfield, NJ. Privately held — engineering, procurement, and construction under one roof, on one warranty.
Every joint, conduit, and connection — backed by the crew that did the work.
Output guaranteed. If your system underperforms its model, we make you whole.
Tier-1 panels & inverters. Manufacturer warranty passed straight to you.
Most solar companies sell you a panel and call a subcontractor. We engineer your system, procure the equipment, and construct it ourselves — three disciplines, one company, zero finger-pointing when something needs to be made right.
In-house engineering team. Structural analysis, energy modeling, interconnection studies, and system design tuned to your facility's load profile — not a one-size-fits-all template.
Direct relationships with leading panel and inverter manufacturers. We specify what we install, and what we install is what's on the contract — backed by 25-year product warranties.
We don't subcontract installation to whoever bid the lowest. Our certified crews build every array, and our 10-year workmanship warranty stands behind every joint, conduit, and connection.
Commercial buyers — go deeper

Full Engineer · Procure · Construct for businesses, multifamily, warehouses, schools, manufacturing, and agricultural facilities. 25-year warranties, in-house crews, fixed-price proposals.
Same engineering rigor we bring to commercial buildings, scaled for your home. Tier-1 panels, real warranties, NJ SuSI + state incentives stacked, lifetime monitoring.
Rooftop, ground-mount, carport, and battery enclosure construction across the tri-state. Licensed electricians, certified racking installers, OSHA-30 crews. Re-roof + PV combined warranties.
Site sourcing, feasibility, interconnection, permitting, off-taker structuring, and capital coordination. Handed off to our own EPC team at NTP — or to a partner EPC if the owner prefers.
Commercial solar is not residential at a bigger scale. Different roofs, different loads, different incentives, different decision-makers. Here's where we've put steel in the ground.
Lower the operating cost of your building portfolio. Sustainability that shows up on the P&L and the ESG report.
Re-allocate utility spend toward classrooms. Outdoor classroom & STEM-curriculum opportunities included.
Big roofs are big assets. Convert vacant rooftop square footage into the cheapest kWh you'll ever buy.
Reduce common-area utility burden, qualify for state incentives, and deliver bill credits to residents.
Lock in long-term electricity costs. Hedge against grid volatility while meeting customer ESG requirements.
Power irrigation, refrigeration, and processing. Ground-mount and barn rooftop arrays with grazing-compatible designs.

Headquartered in South Plainfield, NJ since 2023. Our engineers and field crews mobilize daily across the NJ · NY · PA tri-state corridor — from Long Island to the Lehigh Valley, every county of New Jersey, and the Philadelphia metro. National multi-site capable for portfolios that extend beyond.
From the first phone call to year 25 of monitoring, you'll work with the same team. Here's exactly how a commercial project moves from "interested" to "powered up."
A 20-minute conversation. Tell us about your building, your utility bills, your goals. We tell you whether commercial solar makes sense — honestly. If it doesn't, we'll say so.
Our engineers run the numbers: structural capacity, energy modeling, interconnection feasibility, financing scenarios. You get a fixed proposal — not a placeholder.
We handle the paperwork (permits, utility, incentive applications) while we procure your hardware. Our crews mobilize, build, and commission. Most commercial systems: 8–14 weeks on site.
PTO from your utility, system goes live, monitoring portal in your hand. We watch every kWh for the next 25 years and call you before you call us if anything drifts.
Most commercial systems fail because cheap installs cut corners. We don't compete on cheap. We compete on still-working-in-2050 — and back it with the longest warranty stack in the industry.
No outsourced design. Structural, electrical, and energy modeling done by Reliant engineers before you sign anything.
No subcontracted labor. Licensed electricians, certified racking installers, and OSHA-30 crews — on every job.
What's on the contract is what gets installed. No bait-and-switch on panels or inverters.
We watch every kWh for 25 years and call you before you call us if anything drifts from the production model.
No private-equity rollups, no 1-800 queue. The leadership team that signs your contract is the same team here when something needs to be made right.
Local presence in NJ · NY · PA. National capability for multi-site commercial portfolios.
Quick takes on the questions we hear most. Twelve more answers — including financing structures, install timelines, and how we differ from a broker — live on the FAQ page.
For systems in the 500 kW – 2 MW range, expect 5 to 9 months total — from contract signature to PTO from the utility. Construction itself is the fastest piece (4–14 weeks on site). Most of the calendar is permits and the utility witness test.
For NJ commercial projects with the federal ITC + accelerated depreciation + state SREC stack, payback typically lands at 4–7 years on equipment with a 25-year+ production warranty. We model your specific facility during the proposal phase.
Yes — for both commercial and residential. Commercial: PPA (we own and operate, you pay only for kWh produced at 20–40% below utility rates) or C-PACE in eligible states. Residential: solar loans typically cash-flow-positive from month one.
Three independent warranties stack on every install: 10-year workmanship, 25-year production guarantee, and 25-year manufacturer product warranty. Longest commercial coverage in the industry.
Yes. Same engineering rigor we bring to commercial, scaled for your home. New Jersey's Successor Solar Incentive (SuSI) plus net metering and the state property-tax exemption stack to keep residential paybacks competitive. Most NJ homes see 8–12-year paybacks on equipment with 25-year warranties.

Honest takes on commercial solar economics — payback math, financing structures, demand-charge management, and the incentive stacks most buyers leave on the table.
Permits, capacity studies, witness tests, and PTO. Why interconnection is the longest single step in any solar project — and what slows it down in NJ vs. NY vs. PA.
Asphalt shingle vs. metal vs. TPO vs. EPDM vs. tile vs. slate — every roof type ranked for solar compatibility, with the structural and warranty considerations that actually matter.
Modern monocrystalline panels degrade about 0.5% per year. After 25 years they still produce roughly 87% of nameplate. Here's what that means for your project's lifetime production.
