HeatTime

Turn sunlight hours into a playful oven-energy comparison — learn power of sun!

HeatTime — See how much solar energy your day gives

HeatTime turns everyday sunlight into an approachable energy comparison: enter how many hours of sunlight a surface receives, and HeatTime estimates the energy collected (in kWh) and the equivalent time an oven would run using the same energy.

This app is great for students, curious minds, and anyone who likes simple science-based insights. All calculations are approximate — HeatTime shows the assumptions and lets you tweak irradiance, exposed area, and oven power for a more tailored comparison.

Features
• Convert sunlight hours → energy (kWh)
• Compare that energy to oven/heater running time at a chosen wattage
• Tweak assumptions (irradiance, exposed area, oven power) for realism
• Share results with friends

Note: This is an approximate, educational tool — results depend heavily on sunlight intensity, angle, and real-world losses.
