1. What is a Solar Generator to Power House Calculator?

Definition: This calculator estimates the required solar generator power (in kW) needed to power household appliances based on total load, safety factor, and solar efficiency.

Purpose: It helps homeowners and solar installers determine the appropriate solar generator size for residential power needs.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( P_{kW} \) — Required solar generator power (kilowatts)
• \( \Sigma(P_{load}) \) — Total power of all connected loads (watts)
• \( SF \) — Safety factor (typically 1.2-1.5)
• \( \eta_{solar} \) — Solar system efficiency (typically 0.15-0.20)

Explanation: The total load is converted to kW, then adjusted by the safety factor and divided by solar efficiency to account for real-world conditions.

3. Importance of Proper Solar Sizing

Details: Correct solar generator sizing ensures reliable power supply, prevents system overload, and optimizes energy production and cost.

4. Using the Calculator

Tips: Enter the total wattage of all appliances, safety factor (default 1.25), and solar efficiency (default 0.18). All values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: What is a safety factor in solar calculations?
A: The safety factor accounts for unexpected load increases, system losses, and future expansion needs.

Q2: Why is solar efficiency typically low (15-20%)?
A: Solar panels have conversion losses, and the system has wiring, inverter, and battery efficiency losses.

Q3: How do I find my total load power?
A: Add up the wattage of all appliances you plan to run simultaneously, or use our Load Calculator tool.

Q4: Should I include all my home's appliances?
A: Only include appliances that will run at the same time or that the solar system must support.

Q5: Does this include battery storage requirements?
A: No, this calculates continuous power needs. Battery capacity depends on desired backup time.
