| Scenario | Usage Profile | Estimated Runtime | Notes |
|---|---|---|---|
| 2) Anker E10 Backup Only | High Usage: AC & Hot Tub ON (~50 kWh/day) | 5 - 6 Hours | Battery depletes quickly under heavy load. Once empty, use the Firman generator to recharge the system. |
| Essentials Only: AC & Hot Tub OFF (~12 kWh/day) | 20 - 24 Hours | Powering only fridges, freezer, lights, and internet. Firman can top off battery periodically. | |
| 3) Anker E10 + 10kW Solar | High Usage: AC & Hot Tub ON | Overnight (with risks) | Solar runs the house by day and recharges the battery, but heavy nighttime AC may drain it before morning. Firman provides backup. |
| Essentials Only: AC & Hot Tub OFF | Indefinite (Infinite) | Solar easily outpaces the 12 kWh daily essential load, recharging the battery every day, even in winter/clouds. | |
| 4) Anker E10 + 8.8kW DIY Solar | High Usage: AC & Hot Tub ON | 5 - 7 Hours | The 8.8kW array massively helps extend runtime during sunny days, but heavy AC/Hot Tub loads will still overpower the system and drain the battery. |
| Essentials Only: AC & Hot Tub OFF | Indefinite (Infinite) | The 8.8kW array produces enough power to easily run the essentials (~12 kWh/day) and recharge the battery, even with minor cloud cover. |
You do not need to manually flip breakers if you upgrade to a smart system (like the Anker SOLIX Home Power Panel or a SPAN Smart Panel). A smart panel replaces your standard "dumb" breakers with internet-connected relays, allowing you to set software rules in the app:
If you choose to save money and stick with your existing electrical panel (using the $1,150 interlock/inlet setup), you must manage the loads yourself:
The baseline cost of doing nothing (paying DTE for all power) over 15 years varies based on annual rate hikes. The tables below show the cumulative out-of-pocket costs (Net Upfront + 15 Years of Electric Bills) for each scenario.
| Utility Rate Increase (YoY) | Baseline (No Action) | 1) DTE Surge Plus | 2) Anker E10 Only | 3) E10 + 10kW Turnkey | 4) E10 + DIY Kit |
|---|---|---|---|---|---|
| 0% (Stagnant Rates) | $49,950 | $54,088 | $53,014 | $47,404 (Saves $2.5k) | $33,263 (Saves $16.6k) |
| 3% (Historical Avg) | $61,934 | $66,072 | $64,113 | $51,396 (Saves $10.5k) | $38,227 (Saves $23.7k) |
| 5% (High Inflation) | $71,866 | $76,004 | $73,270 | $54,890 (Saves $16.9k) | $42,504 (Saves $29.3k) |
Option 3 crosses the baseline at Year ~11. Option 4 crosses the baseline much earlier at Year ~5 because of the ultra-low upfront cost, and eventually saves the most overall money.
After running the numbers across all scenarios, Option 4 (Anker E10 + 8.8kW DIY Solar) is the clear winner and our official recommendation.
While Option 3 (Turnkey Solar) provides excellent long-term energy independence, it is severely weighed down by the $12,000+ markup associated with professional rooftop installation. By opting for Option 4, you secure an incredibly capable 8.8kW system that generates nearly the same amount of power, but you bypass the egregious labor costs by utilizing a ground-mount DIY approach. This drops your payback period from 11 years down to an incredible 5 years, making it the smartest financial and functional choice for your home.
