Off Grid & RV Solar Calculator and System Selection Guide
Offgrid & RV Solar Calculator
1. Calculate Your Power Needs
Select appliances that may run at the same time to calculate peak load requirements for proper inverter sizing.
| Appliance | Peak Load | Daily Wh | |
|---|---|---|---|
| Total Daily Power Consumption: | 0 Wh | ||
| Total Peak AC Load: | 0 W |
2. Select Your Solar Package
Experiment with different package levels and see how your system and loads would perform in the simulated real world below. Adjust the Solar irradiance to simulate different seasons. Watch how the generator usage changes with weather and solar system size.
📊 Performance Stats Guide
How many days your batteries can power your loads without any solar input or generator. Higher is better for cloudy weather resilience.
How much excess solar capacity you have beyond daily needs. Higher scores handle cloudy days and seasonal variations better.
How well your inverter can handle realistic peak loads when multiple appliances run simultaneously. Higher scores mean lower risk of tripping breakers.
Percentage of your energy needs met by solar and batteries alone. Higher scores mean less generator runtime required.
3. System Performance Simulation
Weather Simulation
This is a randomly generated weather pattern with sunny, partly cloudy, cloudy and rainy days over 7 days to see how your system will perform.
Solar Efficiency
Solar irradiance represents the efficiency of solar energy conversion. Typical ranges vary by season and location:
- • Summer (Jun-Aug): 80-90%
- • Spring/Fall (Mar/Sep): 60-70%
- • Winter (Dec-Feb): 40-50%
Factors affecting irradiance include panel angle, location, weather, and panel cleanliness. The percentage reflects the amount of available solar energy captured and converted by your solar panels.
