Services

Residential Solar Panel Installation

NEDES helps homeowners cut bills and gain energy independence. The team analyses roof orientation, shading and energy consumption to design an optimised solar panel system. Permitting and grid interconnection are handled by NEDES, managing every detail for a hassle-free experience.

Those two items - permitting and interconnection - are where most residential solar projects actually stall, since both depend on third-party timelines rather than installation capacity.

Battery and Equipment Installation

Battery storage systems provide blackout protection and allow households to shift stored energy into peak-rate periods rather than exporting it.

System Add-On Panels

For clients who have outgrown an existing setup, NEDES expands current solar arrays with high-yield add-on panels and advanced dual-MPPT inverters, boosting a home's kilowatt output without voiding warranties. New photovoltaic hardware is integrated into the original array.

EV Charger Installation

NEDES supplies Level 2 EV charger installations delivering up to 48A (11.5kW) or rapid charging power. Electricians use dedicated 60-amp THHN wiring for hardwired stations, guaranteeing NEC-compliant charging.

Critter Guards

Mesh guarding around panel arrays prevents birds and rodents nesting beneath modules - a common cause of wiring damage and lost output that is far cheaper to prevent than to remediate.

NEDES was named Virginia's top installer in 2025 and works with hardware partners including Tesla, Enphase and Pearl.

Transparent Estimating

NEDES provides all-inclusive solar estimates with no hidden fees. The team shows how available incentives, net metering and financing options - including $0-down leases and PPAs in some cases - reduce the effective cost and accelerate payback. Each free estimate provides a precise breakdown for the property, including projected savings over 25 years.

The 25-year projection matters because solar economics are driven by payback period rather than upfront cost, and that calculation shifts substantially with local incentive structures.
