Off-Grid Solar Calculator
Off-grid solar array & battery storage calculator
What it does
Sizing an off-grid solar power system shouldn't feel like a complex engineering project. The Off-Grid Solar Calculator simplifies the entire process by analyzing your daily appliance loads against location-specific peak sun hours and seasonal irradiance variance. Get instant, accurate calculations for your daily watt-hour usage, required battery storage, and solar panel array capacity.
Calculate your exact off-grid solar and battery requirements based on your specific appliances and location.
• Daily Load Calculation (Wh/day): Calculated by taking the sum total of appliance operating wattages multiplied by estimated daily usage hours. • Battery Bank Sizing (kWh): Modeled around an 80% Depth of Discharge (DoD) for high-efficiency Lithium Iron Phosphate (LiFePO4) batteries to maximize lifespan and autonomy. Total storage capacity factors in your specified days of battery autonomy. • Solar Panel Array Sizing (kW): Evaluated using localized peak sun-hour data (kWh/m²/day). A 15–20% system inefficiency derating factor is automatically applied to account for real-world inverter losses, dust/shading, and cable voltage drops. • Winter & Seasonal Adjustments: Peak sun hours are…from solarblueprintcalc.framer.website

Hello HN! I found that picking out plausible but diverse skin tones for my digital art and game development projects was kind of difficult, and I got curious about if there was a way to define a color space that made it easy. I've built a color picker and procedural generation algorithm based on the space as well as a bunch of other fun js features and demos throughout the page that use the equations. If you find it interesting, I have lots of explanations of how I built it and what properties the space has. The methodology might be a bit shaky, but hopefully the result is as helpful for…

I trained a 125M-parameter transformer to autocomplete piano performances in real time (~108 notes/sec on an iPhone 15). The idea is basically GitHub Copilot or Tabnine, except instead of prompting it with code, you prompt it by playing a few notes on a MIDI piano. The model then continues what you played, entirely on-device. The app is free if anyone wants to try it. Happy to answer questions about the model, training, Core ML, or the many things that didn't work.
