Welcome to Mod Solar - Panel Project, featuring our exclusive Solar Smash technologyβ€”the definitive tool for optimizing solar energy systems before the first panel is even installed. Our app simplifies the complex process of designing rooftop solar arrays by combining advanced geospatial data with intuitive engineering tools to smash through inefficiency and maximize your energy yield. What we do: Solar Mapping & Projects allows users to create high-precision layouts for solar panels directly on digital roof models. By integrating real-time sunlight trajectory and local weather data, the app calculates the exact energy potential of any surface. Key Features: Intelligent Solar Tracking: We analyze the sun’s path throughout the year to identify the "sweet spots" on any roof, ensuring maximum exposure. The "Solar Smash" Advantage: Smash through high utility bills and energy waste. Our Solar Smash algorithm identifies and eliminates design inefficiencies, ensuring your project delivers the highest possible output for your investment. Efficiency Analytics: Get instant calculations on projected energy yield, performance ratios, and potential ROI based on specific panel models and tilt angles. Custom Project Design: Drag, drop, and rotate panels to fit unique architectural constraints while automatically avoiding shaded areas. Automated Reporting: Generate comprehensive PDF proposals for clients, including 3D visualizations, material lists, and estimated carbon savings. Whether you are a professional installer looking to streamline your workflow or a homeowner planning your transition to clean energy, Solar Mapping & Projects provides the data-driven confidence you need to go solar. Empower your roof. Maximize your energy. Build the future.

Group measured test bars by clay, firing and direction, then compare observed shrinkage and size a target from your own range. HOW IT WORKS 1. Open Test Series and name the clay, firing and measurement direction. 2. Record wet, dry and fired lengths for each test bar using consistent units. 3. Review the mean and observed range, calculate a target-size range and share the measurements. Existing shrinkage and studio planning tools remain available. WHAT TO KNOW Results describe the bars you entered; they do not predict every future firing. Lengths must be positive and nonincreasing from wet to dry to fired. Keep clay, firing and direction consistent when comparing. iPhone and iPad.
