FAQs
How well does solar power perform in Rockford’s climate, which includes cold winters and varying sunlight levels?
Solar panels generate electricity from light, not heat, so they remain effective even on cold days. In fact, solar cells operate more efficiently at lower temperatures. Rockford averages about 4.2 peak sun hours per day over the year, which is enough to make a properly sized system cost-effective. Snow typically slides off the glass surface as panels warm in the sun, and any brief production loss in winter is offset by strong summer output. Our design team uses historical weather data and shade analysis to size your array for reliable, year-round performance.
What federal, state, or local incentives are available for solar installations in Rockford?
Homeowners can claim the 30 % Federal Investment Tax Credit (ITC) on the total system cost through 2032. Illinois residents also benefit from the state’s Adjustable Block Program (ABP), which issues Solar Renewable Energy Certificates (SRECs) that can cover roughly 15–20 % of project cost, paid out quarterly for 15 years. ComEd’s net metering policy credits surplus energy sent back to the grid at the full retail rate, further shortening payback. Additionally, Rockford offers streamlined permitting and, for some neighborhoods, modest property-tax abatements for renewable energy upgrades.
What is the typical return on investment (ROI) and payback period for a residential solar installation in Rockford?
For a 7 kW rooftop system—the most common size—installed cost after incentives is roughly $13,000–$15,000. With average annual utility savings of $1,300 and SREC revenue of about $300 per year, payback is typically 7–9 years. Over a 25-year panel warranty period, homeowners can realize $35,000–$45,000 in net savings, representing an internal rate of return (IRR) near 9–11 %. Commercial systems tend to pay back in 4–6 years due to economies of scale and accelerated depreciation (MACRS) benefits.
Can my solar array be paired with battery storage, and what size battery do I need?
Yes. We offer lithium-iron-phosphate batteries from leading brands that integrate seamlessly with our inverters. Sizing depends on your goals: • Backup Power: Covering essential loads (fridge, lights, Wi-Fi, sump pump) typically requires 10–15 kWh. • Peak-Shaving/Time-of-Use: 13–20 kWh lets you draw stored energy during peak-rate hours. • Whole-Home Backup: 25–40 kWh, often achieved by stacking multiple battery modules. All systems include smart-energy management software, mobile monitoring, and automatic islanding during grid outages. We conduct a load assessment to recommend the most economical configuration.
What is the installation process and timeline from contract to power-on?
1. Site Assessment & Proposal (1 week): We perform roof/ground measurements, shade studies, and present a fixed-price quote. 2. Design & Engineering (1–2 weeks): CAD layout, structural review, and electrical single-line diagrams are created. 3. Permitting & Utility Interconnection (2–4 weeks): We submit all paperwork to the City of Rockford and ComEd; approval times vary but are usually under a month. 4. Installation (1–3 days for residential, up to 2 weeks for commercial): Our NABCEP-certified crew mounts panels, wiring, inverter, and (if selected) batteries. 5. Inspection & PTO (Permission to Operate) (1–2 weeks): City and utility inspectors sign off, then ComEd installs a bi-directional meter and issues PTO. Total timeline: approximately 6–10 weeks, weather and permitting dependent.
How much maintenance do solar panels and related equipment require, and what warranties are included?
Solar PV systems are largely maintenance-free. Panels have no moving parts and are self-cleaning with normal rainfall; an annual visual inspection is usually sufficient. We include: • 25-year manufacturer performance warranty (guarantees at least 85 % output in year 25). • 12-year product warranty on panels, extendable to 25 years. • 10-12-year inverter warranty, upgradeable to 20–25 years. • 10-year workmanship warranty covering roof penetrations, wiring, and labor. Optional monitoring service alerts us to any performance drops so we can schedule prompt repairs. Costs after warranty are minimal—typically replacing the inverter once in 20–25 years.
