Home energy planning usually goes wrong when the shopping starts before the load list.
A portable power station, home battery, EV charger, solar array, heat pump, or induction range can all be the right upgrade. They can also be expensive distractions if they solve the wrong problem. The first step is not a product. It is a short map of what your home needs to run.
The 30-minute first pass
Write down five groups:
- Critical loads: refrigerator, modem, phone charging, medical devices, sump pump, heat needed for safety
- Comfort loads: lights, fans, microwave, small appliances, TV, work setup
- Large electric loads: heat pump, water heater, dryer, range, EV charger
- Outage duration: a few hours, overnight, one day, or several days
- Upgrade intent: resilience, lower energy use, electrification, comfort, or all of them
That list is enough to stop most bad buying decisions.
Choose the first path
| If your main problem is… | Start with… |
|---|---|
| Short outages | Outage Priority List |
| Confusing numbers | Watts, kWh, and Loads |
| Backup shopping | Backup Power Sizing |
| Solar curiosity | Solar Panel Sizing |
| Heating and cooling | Heat Pump Buying Guide |
| Kitchen electrification | Induction Cooktop Buying Guide |
The order that usually works
First, reduce waste. Air sealing, insulation, efficient lighting, and better controls shrink the system you need. The Department of Energy makes the same point for renewables: efficiency comes before sizing a renewable system.
Second, plan resilience. Decide what must run during an outage before you compare backup devices.
Third, electrify thoughtfully. Heat pumps, induction cooking, and EV charging can be excellent upgrades, but they may require panel capacity, new circuits, load management, or professional work.
Fourth, maintain what you install. Filters, firmware, battery state of charge, panel cleaning, and test runs matter more than the brochure suggests.

Your next move
Make a one-page home energy note with:
- the loads you care about
- the outage duration you want
- the upgrades you are considering
- the electrical work that may need a pro
- the questions you need answered before buying
Then use the rest of this library to fill in the numbers.
