Goals
The first and most important step in a photovoltaic project is the precise definition of the client's objectives. These goals are derived directly from the individual needs, expectations, and constraints of the client. A thorough needs analysis forms the basis for successful planning and implementation.
Typical goal categories and needs
- Profitability / Economic efficiency
- Low levelized cost of electricity (LCOE)
- Short payback period (Return on Investment)
- Maximum self-consumption rate
- Subsidies (one-time payment, feed-in tariff, etc.)
- Minimization of operating costs
- Energy independence
- Reduction of electricity purchases from the utility company
- Increased self-sufficiency through storage solutions
- Backup power supply in case of grid failure
- Integration with heat pumps, e-mobility, etc.
- Maximum performance / Area utilization
- Highest possible annual energy yield (kWh/year)
- Use of all suitable roof and façade surfaces
- Future-proofing for extensions (storage, wallbox, etc.)
- Aesthetics and architectural integration
- Harmonious integration into the building (in-roof vs. on-roof)
- Color selection (e.g. black modules, frameless, custom modules)
- Consideration of heritage protection or neighborhood regulations
- Origin and sustainability of components
- Preference for domestic or European production
- Environmental standards in the supply chain (e.g. CO₂ footprint, recyclability)
- Manufacturer transparency, warranty conditions
- Digital control & monitoring
- Real-time self-consumption visualization
- Smart home integration (e.g. load optimization)
- Remote maintenance, alerts, automatic fault diagnosis
- Future-proofing & system openness
- Compatibility with future technologies
- Modularity for future extensions
- Manufacturer independence (open standards such as Modbus, SunSpec)
- Regulatory framework & grid compliance
- Compliance with local regulations (ESTI, EnDK, VSE, etc.)
- Grid connection requirements, feed-in approval
- Participation in collective self-consumption (ZEV/RCP)
