A Photovoltaic offer for companies today not only includes solar panels but a complete Energy system with battery energy storage systems (BESS), energy management systems (EMS), and, if applicable, charging infrastructure. This allows companies to maximize self-consumption, reduce grid fees, and secure long-term stable electricity costs.
This post shows what belongs in a modern solar offer, what data is needed, and how companies can get started as quickly as possible.
What belongs in a photovoltaic offer 2026?
Modern PV offers Consider the entire corporate energy system:
- Complete PV system
- Large-scale battery storage (BESS)
- Energy management system (EMS)
- Consumers (production, heating, e-mobility incl. Charging infrastructure)
Only through thorough data analysis can the loads be optimally coordinated to reduce costs. The core competencies should focus on:
- PhotovoltaicsModule, Inverter, Mounting System
- Battery storage: Self-consumption optimization, Peak clipping
- EMSIntelligent control of all energy flows
- Charging infrastructureElectric vehicle fleets
- MonitoringReal-time transparency
Why PV + BESS + EMS is economically superior
PV systems generate electricity when the sun is shining. If the company does not use the electricity it generates, it is fed into the grid at a rate of about 8 cents per kWh. This often happens on weekends or during the early or late hours of summer days. With BESS and EMS, the self-consumption rate typically rises to 95% or even 100%. For a 1,000-kWp system, this can quickly result in annual savings of €200,000. Optimizing self-consumption for a PV system is just one application of a BESS.
What data do we need for your quote?
1. Consumption data (most important)
- Annual load profile (quarter-hourly intervals) → from the energy provider
- Identify peak and base loads
- Consumption time window (daytime/nighttime)
2. Technical Data
- Available areas (roof, open space, carport)
- Static (Roof Load Capacity)
- Grid connection (Capacity – Low voltage/Medium voltage)
- Existing facilities (high-performance?)
3. Economic Framework
- Current electricity rate (price per kWh + base fee)
- Network fees and charges
- Funding programs (KfW, regional programs)
- Financing preferences (Purchase/Contracting)
Typical photovoltaic offers for businesses
CUBE CONCEPTS implements complete energy projects or PV systems starting from approximately 200 kWp. Typical photovoltaic offerings or complete packages for Purchase plants could be, for example:
Medium-sized facility
- Roof/Open space + BESS (500–2,000 kWh)
- EMS Profile (Load Management, Forecasts)
- ROI: 3-5 years
- Investment: €250,000 – €1 million
Larger facility
- Hybrid System (Roof + Open Space) + Large Storage
- Full-EMS (Market Integration, FCR)
- ROI: 3 – 4 years
- Investment: €1-5 million

Frequently Asked Questions
How long does it take to create a quote?
For PV only: Initial consultation + analysis = 2–5 business days. For PV / BESS systems: After all data is provided, 10–14 business days.
What is the cost of a solar quote?
Free and without obligation. Consultation fee may apply only for detailed planning.
Do I need load data?
Yes – Quarter-hourly load profile is essential for precise calculation.
Are there subsidies?
Conditional: For pure PV systems or complete systems, the respective funding landscape must be examined. For systems with BESS, innovation funding programs are possible.
Does Contracting make it possible without equity?
Yes, with Contracting, planning, construction, and operation are fully funded.
