Best for: Smart Home Planners & Tech Enthusiasts.
Most calculators treat solar, batteries, and EVs as separate silos. This "Master Simulator" integrates them all. It models the synergy between your assets—for example, calculating how much solar excess is required to charge your EV daily without drawing from the grid. It visualizes your entire energy ecosystem in one flow diagram.

Start Simulation

Best for: Homeowners Considering Solar Panels.
The first step in going green. Don't rely on a salesman's promise; use the math. This tool uses your location's peak sun hours and your monthly bill to calculate:

• 25-Year Lifetime Savings.

It accounts for panel degradation and local electricity rate inflation. Calculate ROI

Best for: Resilience Planning & Off-Grid Living.
When the grid fails, how long will your lights stay on? This isn't a simple capacity calculator; it's a survival simulator. You select specific appliances (e.g., "Fridge + WiFi + 4 LED Lights") and the tool determines exactly how many hours your battery bank will last based on the specific wattage draw of those devices. Essential for sizing systems like Tesla Powerwall or customized LiFePO4 banks.

Simulate Outage

Not every roof is suitable for solar. For those in open/coastal areas, micro-wind turbines are a viable alternative. This tool estimates the annual kWh production of a turbine based on your average local wind speed and the turbine's swept area diameter

Estimate Wind Power

Best for: Budgeting & Avoiding Tiered Rate Penalties.
Utility bills are often confusing, especially with tiered pricing (where the rate increases as you consume more). This calculator allows you to input your current meter reading and predict your month-end bill. It helps you understand exactly when you cross into a more expensive consumption tier so you can throttle usage before it's too late.

Estimate Bill

Best for: Residents in Hot Climates.
Air conditioning often accounts for 60-70% of a summer electricity bill. Buying the wrong size is a costly mistake:

• Undersized: Runs continuously, never cools, high cost.
• Oversized: Cycles on/off frequently, reducing lifespan and increasing humidity.

This tool calculates the exact BTU/Ton needed for your room dimensions and insulation level. It also calculates the ROI of upgrading to "Inverter" technology versus standard units. Size My AC

EVs often have a higher sticker price, but a much lower Total Cost of Ownership (TCO). This tool compares the long-term economics of two vehicles. It factors in:

• Fuel costs (Gasoline Price vs. kWh Electricity Rate).
• Annual mileage.
• Maintenance savings (No oil changes, fewer moving parts).
