Comprehensive Guide to NWTC Solar Project: Design, Costs, and Energy Solutions

Explore the NWTC Solar Project's advanced system design options, including flat roof, pole mounts, and tracking systems. With an annual electrical consumption of 63,000 kWh, a 52 kW system is required for total offset. Estimated costs range from $210,000 to $410,000 based on mounting types. A 6 kW ballasted roof system can meet conservative household needs within a $30,000 budget, offsetting over 10% of energy. Focus on energy efficiency strategies and the environmental benefits of solar energy for a sustainable future.

  1. Mauthe Center Solar Project NWTC Solar Advanced System Design Class

  2. Possible Mounting Options • Flat roof • Portrait • Landscape • Pole Mount • With Tracking • With Out Tracking

  3. Possible Array Locations

  4. Energy Consumption • Annual electrical consumption: 63,000 kWh/ yr • To completely offset consumption a 52 kW system would be needed • Estimated cost for a 52 kW system (roof mount): $210,000 - $300,000* • Estimated cost for a 52 kW system (pole mount): $312,000 - $410,000* • * cost may vary depending on actual infrastructure requirements

  5. Your Budget • An approximate 6 KW ballasted roof mount PV system would be in line with your $30,000 budget. • This PV system would offset a little over 10% of your present electrical consumption. • A 6 KW PV system would meet the electrical needs for a conservative household. (8 KW would be for the typical household) • A 6 KW PV system would produce approximately 7200 KWH/ year.

  6. Energy Efficiency • Concentrate on energy efficient methods • Ex. Turn off lights, close doors, sectional heating/cooling, occupancy sensors, use natural lighting, power strips, etc. • Replace inefficient components of building • Ex. Furnace, air supply, lighting, windows, insulation, etc.

  7. Flat Roof Design • 6 kW system • Ballasted Racking = No moving parts & easy to maintain • Landscape modules to minimize wind load • Minimal shading for maximum production • Estimated annual production: 7,200 kWh/ yr • Estimated cost: $24,000 - $36,000

  8. Pole Mount Front of Building • 3kW • Minimal shading to maximize output • Increased cost of pole mount = less solar modules • Great visibility/ public awareness • Estimated annual production: 3,600 kWh/ yr • Estimated cost: $18,000 - $24,000

  9. Pole Mount Behind Building (exceeds budget) • 6kW • Minimal shading to maximize output • Tucked away/ less visible • Estimated annual production: 7,200 kWh/ yr • Estimated cost: $36,000 - $48,000

  10. SOLAR ENERGY • PROVIDING A BRIGHT FUTURE • ENVIRONMENTALLY SOUND ENERGY • DISTRIBUTED ENERGY BENEFITS / LOCAL JOBS / LOCAL ENERGY / KEEPS OUR ENERGY DOLLARS IN OUR COMMUNITY. • OFFSETTING FOSSIL FUEL CONSUMPTION • SIMPLE / RELIABLE / DURABLE / LONG LIFE
