FAQ's

AstroEnergi ApS is a 100% Danish-owned energy company founded in 2023 and based in Hvidovre. We design, source and deliver tailored solar, battery, EV charging and energy solutions in close partnership with leading manufacturers, handling the technical and administrative complexity so you get a transparent, hassle-free experience.

We work with homeowners, businesses and facilities, property developers, installers and EPCs, resellers, utilities and grid operators, data centre and AI operators, and the public sector. Every solution is sized to the customer's consumption, site and budget.

Our services cover six areas: Solar Systems, Battery Solutions & BESS, Energy Advisory, Data Centre / AI / Mining power, EV Charging Solutions, and Wholesale & Distribution. We can manage the full project lifecycle, from sourcing and engineering to installation and long-term service.

We are based in Denmark and design our systems for Danish conditions, grid codes and building standards. Our wholesale stock is held in Denmark and Central Europe for fast delivery across the Nordics and Central Europe. If your project is outside Denmark, contact us and we will tell you how we can help.

We handle every phase from energy simulation to grid connection. A project typically includes a PVsol report with energy simulation, shadow analysis and economic forecast, AutoCAD layouts and one-line diagrams, mounting system calculations, and professional installation and grid registration by certified electricians. All drawings, calculations and reports are included.

PVsol calculates your system's expected annual production based on local weather data, roof inclination, shading and panel type. It gives you a reliable estimate of production, savings and payback, and a clear, shareable report that is ideal for banks, investors and authority submissions.

We design for fibre cement, tile, felt and metal roofs, both flat and pitched, as well as ground-mounted arrays. Static calculations ensure the mounting system withstands Danish wind and snow loads, using proven brands such as Nordmount, K2, Weland, Van der Valk and FixNordic.

Yes. For complex or visually sensitive projects we create photorealistic 3D visualisations in SketchUp showing the panels on your roof or property, including shadow and sunlight simulation throughout the year.

Every system is priced to your roof, consumption and chosen components, so we provide a tailored quote after reviewing your project. As a reference, inverter installation with grid registration starts from 9,000 kr. Contact us for a non-binding offer.

Yes. We analyse your consumption, solar production and tariff structure to size the right battery, and verify compatibility with your existing or planned inverter so the system integrates seamlessly with monitoring.

For homeowners with solar, a correctly sized battery can increase self-consumption from around 30% to over 80%, storing surplus daytime production for use in the evening and during peak-price hours. It can also keep power on during outages with a backup solution.

We are vendor-neutral and work with tier-1 manufacturers such as Huawei, BYD and Sungrow. The LFP (lithium iron phosphate) batteries we use are rated for 6,000+ cycles and typically come with 10–15 year performance warranties.

Yes. Our systems are engineered for operating temperatures from -25 °C to +35 °C, with thermal management, ventilation and fire safety designed to meet local building codes and insurance requirements for both indoor and outdoor installations.

Yes. For businesses and developers we design scalable storage that cuts peak demand charges. For utilities and grid operators we deliver grid-scale BESS for frequency regulation, peak shaving and renewable firming, with smart charge and discharge scheduling around Danish time-of-use tariffs.

We supply and install AC chargers from 7–22 kW for workplaces, housing and overnight fleet charging, and DC fast chargers from 50–350 kW from tier-1 brands such as ABB, Kempower and EVBox, all with Nordic service networks.

Our grid-smart designs use dynamic load management to distribute power in real time, preventing overload and peak demand charges, often without costly transformer upgrades. We assess your grid capacity before any equipment is ordered.

Yes. Charging infrastructure can be paired with on-site solar canopies and battery buffers and integrated with your building's energy management system to lower charging costs.

Yes. We plan depot charging for fleets of 20–500+ vehicles, destination charging for workplaces and retail, and future-proof charging for new developments, including smart scheduling, RFID and app access control, maintenance and modular expansion.

Our advisory covers energy audits and site analysis, feasibility and ROI studies, PPA and procurement strategy, grid connection and DSO coordination, and decarbonisation roadmaps. Every analysis includes documented assumptions for audit and stakeholder review.

Yes. We are 100% vendor-neutral. Our recommendations are based on performance data, not manufacturer relationships, and we offer follow-up consultations as markets, regulations and technology evolve.

Yes. We prepare DSO applications, negotiate grid capacity allocation, estimate connection costs for transformers, cabling and metering, and coordinate grid milestones with your construction schedule, from initial inquiry to final energisation.

Yes. We design solar and battery storage solutions for small AI hubs, GPU clusters, server rooms and edge facilities. This includes load assessment and growth planning, complete power architecture and sizing, battery backup for uptime, and power designs ready for liquid cooling and waste heat recovery.

Yes. Co-located solar and battery systems reduce exposure to volatile grid prices. Our hybrid control systems intelligently dispatch between solar, battery, grid and backup generators, and battery storage can be used for peak shaving and backup extension.

Our wholesale programme serves installers and EPCs, resellers and retailers, and project developers. We supply solar modules, inverters, LFP batteries, EV chargers and balance-of-system components from tier-1 manufacturers with verified IEC certification and warranty terms.

We maintain regional stock in Denmark and Central Europe with predictable replenishment and advance reservation. Our online portal shows real-time stock levels, incoming shipments and backorder status so you can plan your projects with confidence.

Every partner gets a dedicated account manager, competitive volume pricing, project kitting with pre-configured inverters and labelled components, rapid spare part dispatch, product training, and marketing materials. Flexible credit terms are available for established partners.

Send us an inquiry through our contact page and select "Distribution or wholesale" as the inquiry type. Our wholesale team will contact you to discuss your volumes, pricing and partnership terms.

Fill out the inquiry form on our contact page, choose the inquiry type that matches your project and tell us a little about your needs. Our team responds within two business days with next steps and a non-binding offer.

Yes. We handle the necessary analyses, documentation and approval processes for you, including grid registration. Our documentation package also simplifies insurance, authority approvals and any future sale of the property.

Installations are carried out by certified Danish electricians. All work is registered and tested before handover, and we provide functional testing, system setup and user training so you know exactly how your system works.
