# Solar Panels Manage your solar panel inventory with specifications, documentation, and media. ## Adding Panels ### From Powerlily Database 1. **Equipment** → **Panels** → **"Add from Powerlily List"** 2. Browse and select panels 3. Customize as needed Pre-configured panels include complete specs and save data entry time. ### Creating Custom Panels 1. **Equipment** → **Panels** → **"New Panel"** 2. Fill in specifications 3. Upload documentation 4. Save ## Basic Specifications **Name:** Display name shown in quotes and catalog - Example: "REC Alpha Pure-R 405W" **Model:** Manufacturer model number - Example: "REC-405-AA-PURE-R" **Brand:** Select from brand list or enter custom **DC Watts:** Nameplate power rating - Standard Test Conditions (STC) - Critical for system sizing - Residential typical: 350W-450W **Description:** Rich text product information, key features, technology highlights ## Performance Specifications **Efficiency:** Conversion efficiency percentage (e.g., 21.5%) - Optional but recommended - Standard: 17-19%, Premium: 21%+ **Degradation Rate:** Annual power loss percentage - **Critical for 30-year projections** - Standard: 0.5-0.7%, Premium: 0.25-0.5% - Dropdown selector: 0.01% to 1.00% - Affects all production estimates and ROI calculations **Bifaciality:** Rear-side gain for bifacial panels - Value: 0 to 0.99 (0% to 99%) - Typical bifacial: 0.70-0.75 - Leave blank/0 for monofacial panels - Only relevant for ground mount or white roofs ## Physical Dimensions **Height & Width:** Panel dimensions in inches - **Required for 3D design tool** - Standard 60-cell: ~65" × 39" - Standard 72-cell: ~78" × 39" - Check manufacturer spec sheet **Without dimensions, panels can't be drawn in design tool** ## Advanced Fields (Optional) **Family:** Module type (Monocrystalline/Polycrystalline) **Nameplate Specifications:** - **Isc:** Short-circuit current (A) - **Voc:** Open-circuit voltage (V) - **Ipmax:** Current at max power (A) - **Vpmax:** Voltage at max power (V) - **NOCT:** Nominal operating cell temperature (°C) **Temperature Coefficients:** - **Temp Coeff Voc:** Voltage temperature coefficient (%/°C) - **Temp Coeff Pmax:** Power temperature coefficient (%/°C) **Low Temperature & NOCT Values:** - **IPmax Low/VPmax Low:** Performance at low temperature - **IPmax NOCT/VPmax NOCT:** Performance at NOCT *These advanced fields are for detailed modeling and usually not required* ## Warranties **Product Warranty:** Equipment/workmanship coverage (years) - Typical: 10-15 years, Premium: 25 years **Power Warranty:** Output guarantee (years) - Typical: 25-30 years ## Pricing **Value:** Your wholesale cost per panel - Quoted totals calculated automatically from BOM - Update when costs change - Typical range: $150-$400 **Recommended Inverter:** Optional pairing suggestion ## Visibility & Media **Visible:** Toggle to show/hide from new quotes - Disable for discontinued products or out of stock - Existing quotes unaffected **Draw Ready:** Automatic validation - Requires: valid width, height, and watts - Panels without dimensions can still be used in quotes, just not drawn **Images:** Upload multiple product photos (JPG, PNG, HEIC) **Spec Sheet:** PDF datasheet for customers **Additional Documents:** Installation guides, warranties, certifications **Video:** YouTube video ID or URL ## QR Codes Auto-generated QR code for each panel linking to its public equipment page - Available as SVG or PNG - Use on brochures, boxes, materials ## Management **Editing:** Changes affect new quotes only; existing quotes unchanged **Deleting:** - Can delete: Unused panels - Cannot delete: Used in any quote - Alternative: Set Visible = False **Cloning:** Duplicate to create variants with different pricing or specs ## Best Practices - Always verify specifications from manufacturer datasheets - Degradation rate affects 30-year projections - don't guess - Wrong dimensions break design tool drawings - Include spec sheets and images for professional presentation - Update pricing regularly --- **Related:** [[Inverters|Inverters]] | [[Equipment|Equipment Overview]] | [[Equipment Catalogue|Equipment Catalogue]]
