North Carolina Homes Case Study
12 kW Solara Power: Backup Battery + Solar for North Carolina Homes
System Overview
Solar Panels: 12 kW PV array (~30 high-efficiency panels)
Inverter: 12 kW Solara Hybrid Inverter
Battery Storage: Two Solara Power Batteries, 14.3 kWh each (28.6 kWh total, ~25.7 kWh usable)
Average Home Size: 3,000 sq ft, all-electric or hybrid
Backup Coverage: Refrigerator, Wi-Fi, lighting, HVAC fan, washer/dryer, kitchen outlets
Power Flow: Solar → Inverter → Home Loads + Battery → Grid Export
How the System Supports the Day
AM: Solar panels power home and charge both Solara batteries.
PM: Solar runs home, fills batteries, and sends extra power to the grid.
Evening: Battery energy powers essentials like lights, fridge, HVAC, and outlets.
Night: Reserve energy lasts ~23–32 hours depending on usage.
Next Morning: Solar recharges batteries automatically.
System Math and Runtime
PV Production: 12 kW array ≈ 36–54 kWh/day (depending on season and shading).
Battery Runtime: 25.7 kWh ÷ 1.1 kW load ≈ 23 hours.
Light Use Mode: ~0.8 kW load ≈ 32 hours of autonomy.
Inverter Power: 12 kW continuous, supports most home loads simultaneously.
Cost & Incentive Summary (North Carolina 2025)
By integrating the Solara Power hybrid inverter and battery system, homeowners in North Carolina can expect:
- Up to 35 % lower upfront cost compared with other major brands.
- Faster ROI (approx. 6–8 years typical).
- Longer runtime (28.6 kWh total storage ≈ 25.7 kWh usable).
- Full eligibility for Duke Energy PowerPair and the 30 % Federal ITC
Florida Homes Case Study
Balancing Generator and Solar: A Florida Home Backup Power Consultation
Overview
In this case study, we showcase how Solara Power provided a customized backup power solution for a 2,500 square foot Florida home with a swimming pool, averaging about 38 kWh per day. The client initially wanted a generator-only solution to avoid the cost of solar panels.
Our Process
- Needs Assessment:
We assessed the client’s energy usage and explained that while a generator could provide backup power, it might not be the most cost-effective or sustainable long-term solution. Generators rely on fuel and have ongoing maintenance costs. In contrast, integrating solar panels could reduce operational costs over time. - Proposal Development:
We provided a detailed cost breakdown. The generator and battery system met the client’s initial budget, but adding solar panels increased the overall investment. We emphasized that a solar-plus-generator solution would provide more reliable and cost-efficient backup power over time. - Client Education:
We explained why a generator alone might not be ideal. Relying solely on a generator means dealing with fuel costs and potential supply issues during extended outages. By contrast, solar panels could lower those costs and provide a greener, more sustainable option.
Outcome
The client decided to wait until they could budget for the combined solution. They appreciated our transparency and the insight into why a generator alone might not fully meet their long-term goals. This case study shows how Solara Power tailors Florida home backup power solutions to ensure clients understand all their options.
