Path-Q Solar
Will solar save money if most of my electricity use happens after sunset?
Answer
It can, but the savings may be lower than for a home that uses more electricity while solar is producing. The outcome depends on how surplus daytime energy is credited or valued, whether loads can be shifted to daytime, and whether storage is justified by the additional cost.
Key points
- Solar first serves simultaneous on-site loads; unused production may be exported or otherwise treated under the applicable arrangement.
- Laundry, water heating, vehicle charging, or other flexible loads may be shifted if practical.
- A battery can move some solar energy into evening hours but adds cost, losses, capacity limits, and replacement considerations.
- Savings should be modeled using hourly or interval consumption when timing is important.
What it depends on
- Hourly electricity-use profile
- Export compensation and bill structure
- Ability to shift flexible loads
- Battery cost, usable capacity, and operating objective
- Solar production timing and system size
Risks and trade-offs
- Annual kWh offset does not necessarily equal bill savings.
- A battery may improve self-use but still fail to provide attractive financial value.
- Oversizing solar for nighttime use can increase cost if exported energy is not valued similarly.
Information you may need
- Hourly or interval usage data
- Current bill structure and export treatment
- Flexible-load schedule
- Solar-only and storage scenario estimates
