Feasibility Study Components
Our studies cover every aspect your community needs to understand before making a solar decision. Each component is tailored to your specific building and situation.
Building & Rooftop Assessment
We evaluate your building's physical characteristics: roof dimensions, orientation, structural capacity, shading from nearby structures, and access considerations. This determines realistic panel placement and expected performance throughout the year.
Solar Production Calculation
Using your building's specific data and local solar radiation patterns, we calculate expected monthly and annual electricity generation. These projections account for seasonal variations, weather patterns, and system efficiency losses.
Distribution Model Design
We develop multiple fair allocation systems for sharing generated electricity among community members. Models can be based on apartment size, consumption patterns, investment contribution, or hybrid approaches. Each option is explained with advantages and trade-offs.
Individual Savings Analysis
For each apartment type in your building, we calculate estimated monthly and annual cost reductions based on typical consumption patterns and current electricity rates. This shows residents what solar would mean for their personal bills.
Administrative Procedures Guide
We outline every required step: distribution company applications, technical permits, community voting requirements, legal documentation. You'll understand the complete administrative path before committing to the project.
Community Meeting Presentation
We can attend your community meeting to present study findings and answer resident questions. This ensures everyone understands the information and can discuss concerns before voting.
Technical Assessment Process
Our rooftop evaluation goes beyond simple measurements. We assess:
- Available roof area and optimal panel layout configurations
- Structural load capacity and any reinforcement requirements
- Orientation angles and their impact on energy production
- Shading patterns from nearby buildings, trees, or roof structures
- Access routes for installation and future maintenance
- Electrical infrastructure and connection points
This comprehensive assessment ensures production estimates reflect your building's actual conditions, not idealized scenarios.
Distribution Model Options
There's no single "correct" way to allocate solar electricity among community members. We present multiple models so your community can choose the approach that matches your values.
Size-Based Allocation
Electricity distributed proportionally to apartment size. Larger units receive more solar power, smaller units receive less. Simple and intuitive, but may not match actual consumption patterns.
Consumption-Based Allocation
Distribution follows actual electricity usage patterns. Higher-consuming units receive proportionally more solar power. Reflects real needs but requires consumption data tracking.
Investment-Based Allocation
Solar power allocated according to each unit's financial contribution to installation costs. Units that invest more receive more benefit. Flexible but requires careful financial planning.
Equal Distribution
All participating units receive equal shares regardless of size or consumption. Simplest approach but may feel unfair if apartments vary significantly in size or usage.
Hybrid Models
Combinations of the above approaches. For example, base allocation on size but allow additional investment for increased share. We can design custom models for your community's specific needs.
Opt-Out Provisions
Mechanisms for units that don't wish to participate. How is their roof space handled? Do they have future opt-in rights? These details matter and need clear definition.
Savings Projection Methodology
Our savings calculations are based on realistic assumptions and current market conditions:
- Current electricity rates from your distribution company
- Typical consumption patterns for different apartment sizes
- Expected solar production based on your building's assessment
- Self-consumption versus grid export scenarios
- Seasonal variations in production and consumption
- System efficiency and performance degradation over time
We provide both optimistic and conservative scenarios so your community understands the range of potential outcomes. Real savings depend on actual consumption behavior and future electricity rate changes.
Administrative Roadmap
Understanding required procedures helps communities plan timelines and responsibilities.
Community Approval
Legal requirements for community voting under Spanish property law. What percentage of owners must approve? How should the vote be documented? What information must be provided to all owners before voting?
Distribution Company Application
Required documentation and procedures for connecting a collective self-consumption system. Technical specifications, connection agreements, and timeline expectations for approval process.
Technical Permits
Municipal building permits, structural engineering certifications if needed, electrical installation approvals. We outline what permits your specific project will require based on building characteristics.
Legal Documentation
Agreements between community members regarding distribution, maintenance responsibilities, cost sharing, and dispute resolution. These documents protect all parties and clarify expectations.
Installation Coordination
If the community decides to proceed, how to select an installation company, what to include in contracts, and how to verify work quality. We provide guidance even though we don't perform installations.
