1. What is an RV Solar Power System Calculator?

Definition: This calculator estimates the size of solar power system needed for an RV based on daily energy consumption and available sunlight hours.

Purpose: It helps RV owners determine the appropriate solar panel capacity to meet their energy needs while off-grid.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( \text{Size} \) — Solar system size (kilowatts)
• \( \text{RV Load} \) — Daily energy consumption (kilowatt-hours)
• \( \text{Hours} \) — Peak sunlight hours available (hours)

Explanation: The daily energy requirement is divided by the available sunlight hours to determine the required solar panel capacity.

3. Importance of Proper Solar Sizing

Details: Correct sizing ensures reliable power supply, prevents battery damage from over-discharge, and optimizes system cost.

4. Using the Calculator

Tips: Enter your RV's daily energy consumption in kWh and average peak sunlight hours (default 4). All values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: How do I determine my RV's energy load?
A: Calculate by adding up the wattage of all appliances multiplied by their daily usage hours, then divide by 1000 to get kWh.

Q2: What's a typical sun hour value?
A: Most locations average 4-6 peak sun hours daily, but this varies by season and location.

Q3: Should I include a safety factor?
A: Yes, consider adding 20-30% to the calculated size for cloudy days and system inefficiencies.

Q4: Does this include battery storage?
A: No, this calculates panel size only. Battery capacity should be sized separately based on your needs.

Q5: How does temperature affect the system?
A: Solar panels lose efficiency in high heat. In hot climates, you may need 10-25% more capacity.
