List the activities and equipment
Write down the equipment you expect to use, including lighting, charging, refrigeration, communications and anything that runs while you are away. Record the exact model where you know it. Distinguish an essential need from something you would simply like to have.
Record use, not just the label
For each item, note how long and how often you expect to use it. Gather the manufacturer’s consumption information and, where appropriate, measured energy use. Keep power ratings, energy consumption and supply requirements separate; they describe different things. Leave uncertainty in the plan instead of inventing a precise figure.
Compare a visit with an empty week
Make a second list for equipment that stays on between visits. Ask what happens if the supply runs out and which tasks can wait. Include the need to recharge before the next stay. These scenarios give a designer or qualified installer a much better starting point than a panel count alone.
Turn the list into a checked design
Save your equipment list, expected operating hours and open questions in your project. Use the exact equipment instructions and qualified help to settle installation, compatibility and protection requirements. This first guide organizes the inputs; it does not specify wiring, battery size or a guaranteed power supply.
