The four steps at CUBE Buying a photovoltaic system

Design when purchasing a PV system
- Planning a PV system and design based on the current and future electricity demand as well as the local conditions, e.g. size and nature of the roof surface(s)
- For Germany: Planning in accordance with VDE 0100 Part 712, clarification of e.g. necessary disconnections, feed-in management in accordance with TAB and VDE 4105 NS and 4110 MS
- Application for the grid compatibility test with the grid operator, or in accordance with country-specific requirements
- Investigation of grid compatibility with evaluation of additional costs, e.g. for medium-voltage systems, maintenance of existing protection, switch-off specifications and associated certification
- Control and clarification of local conditions, e.g. glare effects near airports, increased pollution from nearby exhaust/particle/dust-producing industries
- Use of PV SOL as bank-accepted planning and simulation software
- Analysis and delimitation of third-party consumers/meter management
- Clarification with internal plant interfaces, e.g. fire protection, plant fire department, environmental protection, occupational health and safety, etc.
- Assistance with checking the structural analysis, system structural analysis is provided
- Planning the necessary future charging infrastructure with a GHG concept
- Tender for the system in the CUBE-Solateur network in accordance with standardized or country-specific specifications
Calculation when purchasing a PV system
- Clarification and implementation of the individual investment strategy (operator model)
- All calculations are based on real current or realistic future electricity purchase prices from the grid
- CUBE-internal, scalable calculation tool, which was also co-developed by banks for financing PV systems, among others
- The calculations are bank-compliant and take into account business and tax aspects
- Each PV system is considered economically in such a way that CUBE CONCEPTS would also invest in the system with financial partners
- Checking the funding options and applying for funding for charging infrastructure and peak load management. If funding is approved, preparation of the complete documentation and process support until the funding is received
- In Germany: Implementation of the operator model to save 60% of the EEG surcharge, if necessary
- Preparation of all corresponding EEG-compliant contracts
Construction of a solar system for commercial use
- Presentation and evaluation of solar contractor offers, taking into account all qualitative, technical, commercial and local aspects (CUBE internal scoring model)
- Organization and ordering of telecontrol technology, commissioning of system certificate/protection technology
- Coordination with direct marketers, interface specifications, hardware ordering
- Possible division of solar power (DC/AC): Taking over the general contractor negotiations, interface definition and contract preparation
- Preparation of purchase and construction contract with optimized payment terms to exclude construction risks
- Coordination of delivery and construction dates
- Documentation of the location of WR/cabinets and cable routes to minimize queries from tradesmen
- First drone flight before the start of construction/photo documentation
- Execution of a roof handover protocol
- Second drone flight during the construction phase/photo documentation
- Invoice control solar installer and release recommendation
- Ongoing construction management
- For Germany: EEG commissioning logging
- Third drone flight after commissioning/photo documentation
- Registration of the installation in the market master data register or national register requirements
- Coordination of appointments and clarification of any details with the grid operator regarding grid access
- Monitoring/logging of network performance
- Instruction on system operation/fault analysis etc. via Ampere Cloud
- Onboarding the system
- Mounting the hardware (monitor) incl. Raspberry (optional)
- Integration in CUBE VISION
Energy monitoring for a solar system
- Insurance: Adjustment/inclusion in the comprehensive CUBE insurance package, incl. business interruption insurance (additional costs due to external power supply, loss of income from the feed-in tariff, dismantling and reassembly costs)
- Notification of the system to the grid operator, the Federal Network Agency and, if applicable, the transmission grid operator (EEG levy), customs (electricity tax) and other authorities
- Conclusion of a direct marketing contract or corresponding national regulations
- Submission of all necessary notifications or the preparation, information or statements ready for signature that are required by law in each case
- Processing and checking all invoices
- CUBE VISION as Photovoltaic monitoringIndividual widget arrangement, "Count Down" programming (optional), alternatively free access to the API interface
