Solar Power System Designer

Enter the daily load and the sun hours and Solar Power System Designer computes the system size directly on the page, so you can adjust assumptions and watch the result follow.

1. 1

   Step 1

   Enter the electrical values: voltage, current, resistance.

2. 2

   Step 2

   After entering the values, click "Calculate" to view the output.

3. 3

   Step 3

   Save or share the result as needed.

• 1

  Labels first: Solar Power System Designer applies its computation to the daily load and the sun hours exactly as typed, so a wrong unit or a comma read as a decimal mark shifts the system size silently.

• 2

  Test scenarios one at a time: change the daily load while the rest stay fixed and the movement in the system size is attributable to that single change, which turns Solar Power System Designer into a comparison tool, not a one-shot answer.

• 3

  Save the input set beside each result before closing the page: when your numbers change, Solar Power System Designer only needs the moved fields re-entered, and the documented assumptions keep the old and new outputs comparable.

• Swapped inputs: Solar Power System Designer cannot tell the daily load from the sun hours, and the system size still looks plausible; re-read every labeled field before you quote the result.

• Copying the output and discarding the inputs: a bare result cannot be audited later, because the page has no memory of yesterday's entries — the assumptions travel with the number or the number is worthless in a month.
