Sussex County utility rates range from 15 to 19 cents per kWh depending on your provider, with increases projected through 2026. Delaware’s incentive stack strengthens the case: Green Energy Program rebates or DEC solar grants reduce upfront cost, SRECs, full retail net metering, and Delaware charges no state sales tax on equipment. Unlike neighboring Pennsylvania, which charges 6% sales tax on solar equipment and offers no property tax exemption, Delaware’s zero-sales-tax advantage makes Sussex County one of the most cost-effective markets for going solar.
From Rehoboth beach homes to Georgetown subdivisions to western Sussex farmsteads, Sunwise designs systems for Sussex County’s built environment.
Sussex County’s housing ranges from coastal homes and 55+ communities near the beaches to ranches, colonials, and farmhouses in Georgetown, Seaford, and the western part of the county. Sunwise uses premium panels and microinverters, and we handle permitting across every Sussex County jurisdiction.
Sussex County’s commercial and agricultural landscape includes poultry processing facilities, Route 1 hospitality and retail buildings, distribution warehouses, and large-footprint farm operations. The 30% federal ITC (available through July 4, 2026), accelerated depreciation, and Delaware SRECs make commercial solar a strong investment.
Coastal storms and summer weather create outage risk across Sussex County, and a grid-tied solar system shuts down by default. A battery keeps critical systems running during outages. For homes needing a new roof, Sunwise bundles both into a single project.
A Sunwise Energy Specialist assesses your roof, reviews your utility usage, and models projected production and savings based on your actual energy consumption.
Sussex County permitting varies by jurisdiction. Incorporated towns like Rehoboth Beach, Lewes, Georgetown, and Seaford handle their own permits, while Sussex County Council governs unincorporated areas. Sunwise manages the full application regardless of location.
Our in-house crews install your system in under a day. Every project uses premium panels and microinverters, installed to Delaware building and electrical code.
Sunwise coordinates your utility interconnection and meter setup with DEC, Delmarva Power, or your municipal utility. Once your provider grants Permission to Operate, your system goes live.

A consultation is free, pressure-free, and designed to help you understand whether solar makes sense for your home.
Sunwise Energy installs solar across all of Sussex County, Delaware's largest county by area. Whether you're on the coast, in a 55+ community, or on agricultural land in western Sussex, our team knows the local permitting, utilities, and housing stock.
Delaware's most popular beach resort communities. Rehoboth's mix of year-round homes, vacation properties, and condos creates diverse solar opportunities. Beach homes often have strong sun exposure and high summer cooling costs, making solar particularly effective. Note: Rehoboth has its own municipal permitting process.
Historic Lewes sits at the mouth of Delaware Bay, with a mix of older homes and newer coastal development. Milton has seen rapid residential growth with newer subdivisions well suited for solar. Lewes operates a municipal electric utility through DEMEC, which has its own incentive programs.
The county seat, centrally located with a mix of established neighborhoods, newer subdivisions, and rural properties surrounding the town. Georgetown's housing stock includes ranches, colonials, and manufactured homes, most with favorable solar exposure.
Western Sussex communities with a mix of small-town residential neighborhoods and surrounding agricultural land. Larger lots, fewer trees, and higher energy usage from electric heating make many homes in this area strong solar candidates. Seaford operates a municipal electric utility.
Inland communities between the coast and western Sussex, with growing residential development, 55+ communities, and commercial activity along Route 113. Housing is predominantly single-family with good roof exposure.
Sussex County has one of the highest concentrations of active-adult and retirement communities in the Mid-Atlantic. These homes are typically newer construction with consistent roof angles, minimal shading, and predictable energy usage patterns that make solar sizing straightforward and savings reliable.
