THE SHORT ANSWER
Keep all twelve months in the comparison and mark when the home is occupied. An annual total without the occupancy pattern can hide the months that drive purchases, exports and the remaining bill.
Make the calendar before choosing a system size
Create twelve rows, one for each billing period. Add columns for kWh bought, billing days, whether the home was occupied, and any unusual equipment or household changes. Where available, add interval or daily usage records. A Sarasota mailing address is not enough to identify the electricity provider; use the bill’s utility and service address.
Mark uncertain inputs instead of silently filling them with an average. If a new owner plans a different schedule, keep the previous owner’s records as a historical case and create a separate proposed-occupancy case. This makes the limits of an early estimate visible.
See what a single-month shortcut misses
Suppose six occupied months each used 900 kWh and six away months each used 300 kWh. The annual total would be 7,200 kWh. Multiplying the 900 kWh occupied month by twelve instead gives 10,800 kWh, a 3,600 kWh overstatement. These are invented worksheet numbers, not a typical Sarasota home or a solar production forecast.
Now change the future plan to nine occupied months and three away months at those same illustrative levels. The result becomes 9,000 kWh. That difference belongs in a clearly labeled scenario. It should not be blended into the measured year or presented as a guaranteed future bill.
Ask how unused energy is treated over the year
For an FPL account, its FAQ distinguishes credits carried through the year from the settlement of an unused reserve in December. [1] Ask the proposal reviewer to explain the applicable current treatment alongside the month-by-month model. Do not assume a large year-end energy surplus has the same dollar value as avoiding purchases throughout the year.
Have the reviewer show expected self-use, exports, purchases and continuing charges where the available data supports that breakdown. If the proposal only has an annual savings total, request the assumptions behind it. Keep rates, weather assumptions and future occupancy changes distinct so each can be revised without losing the baseline.
Include the practical away-from-home handoff
Decide who can receive monitoring alerts and whom the household will contact for service while away. Ask how access for an accepted service visit is arranged. Save the equipment record and support details somewhere both the homeowner and authorized contact can find them.
When comparing Origin Direct with another proposal, use the same occupancy calendar and separate the installation price from payment terms. Ask which parts of the estimate are property-verified and which remain provisional. The useful result is an appropriately explained project, not the biggest array that fits the roof.
Before your next conversation
- Gather twelve billing periods, including away months.
- Separate historic occupancy from future plans.
- Ask for monthly energy and continuing-charge assumptions.
- Confirm the utility’s current annual reserve treatment.
