FAQs
What solar incentives and rebates are available to Jefferson City homeowners?
Missouri offers a state tax credit for solar equipment, Jefferson City residents qualify for a 26-30 % federal Investment Tax Credit (ITC), and Ameren Missouri currently pays a one-time solar rebate of up to $0.25 per watt (rebate levels change as capacity blocks fill). In addition, net metering lets you earn full retail credit for every excess kilowatt-hour sent back to the grid, lowering future bills.
How much sunlight does Jefferson City receive and how does that affect system sizing and savings?
Jefferson City averages 4.5–5.0 peak sun-hours per day over the year—enough to generate roughly 1,300–1,450 kWh per kW of installed DC capacity. A typical 7 kW residential system will therefore produce about 9,000–10,000 kWh annually, covering 80–110 % of an average home’s usage and saving $1,100–$1,400 a year at current Ameren Missouri rates.
Will my existing electrical service need upgrades before going solar?
Most homes with a 200-amp service panel can accept up to a 10-kW array without upgrades. If your panel is 100 amps or older, we may recommend a new 200-amp main panel or a load-side tap to meet code and utility interconnection rules. Our site assessment includes a full inspection of conductors, grounding, and available breaker space so any necessary upgrades are priced into your proposal upfront.
How long does a solar installation take from contract to energization?
Permitting with Jefferson City Building & Code Enforcement typically takes 1–2 weeks. Utility interconnection approval adds another 1–2 weeks. After permits are issued, on-site installation is usually completed in 1–3 days for most homes. Final inspection and utility meter swap can add 7–10 days. From signed contract to permission to operate (PTO), plan on 4–8 weeks, though larger or more complex projects can take up to 10 weeks.
How will my solar system perform during Missouri winters and severe weather?
Panels still generate power on cloudy days, though output drops 20–60 %. Jefferson City’s winter snow usually slides off the glass within a day or two due to the panels’ dark surface and south-facing tilt. Systems are engineered for 140 mph wind loads and 30 psf snow loads—exceeding local code. During grid outages, a battery backup or hybrid inverter is required for power; standard grid-tied systems shut off for line-worker safety.
What warranties and maintenance services do you provide?
Our Tier-1 panels carry a 25-year power-production warranty (at least 84–86 % output in year 25) and a 25-year product warranty. Inverters come with a 12-25-year warranty depending on model, extendable to 25 years. We provide a 10-year workmanship warranty covering roof penetrations and electrical labor. After installation, we offer optional annual inspections, real-time monitoring, and a 5-year free preventive maintenance plan that includes one onsite checkup per year.
