Solar PV for business: sized to your consumption profile and site conditions.
We design, build and maintain commercial and industrial solar PV systems in Poland, from 50 kWp to 10 MWp, for manufacturing, logistics, retail and services. Capacity and configuration follow your 15-minute load profile (interval data from your meter), self-consumption, roof or ground conditions, grid connection and operating constraints.

Solar PV 50 kWp–10 MWp
Sized to the 15-minute load profile
Rooftop, ground-mounted, carport
In brief
A PV system makes sense for a business when its output matches actual consumption, the site allows safe installation and the economics still work once the full scope of the investment is included. .KWARTZ designs, builds and maintains systems from 50 kWp to 10 MWp. Before recommending anything, we look at the 15-minute load profile, self-consumption and grid connection, compare roof, ground and carport options, and check variants with battery energy storage (BESS) and reactive power compensation. The model also covers the Polish capacity charge (applied 07:00–22:00 on working days), the contracted capacity agreed with the distribution system operator (DSO) and excess capacity charges. If the initial option has constraints, we assess BESS, alternative installation locations, phasing and financing, checking the delivery conditions for your site.
Who it is for
Manufacturing, logistics, retail, services and larger organisations
Manufacturing
Food, chemicals, printing, pharmaceuticals: high consumption and critical circuits.
Logistics and warehouses
Large roofs. We check load capacity, documentation, DAFA guidelines (DAFA is the Polish association of flat roof and façade contractors), cable routes and access for later operations and maintenance (O&M).
Retail, services and multi-site chains
Single-site and multi-site organisations: we compare consumption profiles and build one technical standard.
Data for the decision
What we check before recommending system size
The 15-minute load profile, invoices and tariff, grid connection conditions, roof or ground documentation, planned changes in consumption, operating constraints and your financial assumptions.
The technology follows your profile, not a ready-made package
01
PV system
Sized to current consumption and achievable self-consumption, taking into account the roof, ground or car park, the grid connection and future maintenance.
Engineering, procurement and construction (EPC): design, approvals, supply, installation, commissioning, documentation and ongoing maintenance, with clearly defined responsibilities.
Commercial solar PV: from your load profile to project options
We explore your needs
We establish your goals and site conditions
We discuss your business needs and budget. We assess the load profile, available roof, ground or parking area and grid connection conditions. These inputs define the options to compare.
We assess alternative options
We adapt the technology and scope
For low self-consumption, we assess BESS; for roof or ground constraints, we explore another installation location. We compare grid connection configurations, phasing and financing. The analysis establishes the conditions for feasibility.

Neuca, Zielona Góra
147 kWp · 2024
The PV system is integrated with the site’s backup supply. The scope also includes annual inspections.
We check which work can run alongside operations and which needs a planned shutdown, a switchover or a test in an agreed window.
01
Analysis and design
Based on data (15-minute load profile, documentation), without going onto the shop floor.
02
Off-site prefabrication
Structures and switchboards are prepared before we arrive on site.
03
Installation with a risk plan
Planned around health and safety, access, weather, production and other trades.
04
Critical connections in an agreed window
A planned shutdown or a weekend, agreed with your maintenance team.
05
Commissioning and acceptance
Tests, as-built documentation, handover.
EPC delivery: design, procurement and construction under one contract
We combine design, approvals, procurement and installation. The next stages are commissioning and acceptance documentation. Before work starts, we agree the scope and responsibilities; after commissioning, we can provide ongoing maintenance and monitoring.
If you already have design documentation, we review it before pricing the works. If the project starts with an assessment of consumption, we first review the site data and project feasibility.
Carports for business
Solar carports: the car park as an energy source
A carport combines a supporting structure, a PV system and car park infrastructure in one project. It can complement a rooftop or ground-mounted system, replace roof space that is not available or form part of a new car park. We act as designer and EPC contractor on the client’s side, not tied to one manufacturer’s catalogue.
01
Foundations follow the design
Reinforced concrete or precast footings, or screw piles. The choice follows the ground investigation, structural calculations, groundwater level, underground utilities and how the works are organised on a car park that stays in use.
02
One energy model
PV output is modelled with site consumption and future EV charging. EV chargers, an energy management system (EMS) and battery storage are added only when the data justify them.
Completed carport · medical sector
Clinico Medical · 100 kWp
Clinico Medical Sp. z o.o., part of the Fresenius Kabi group, needed a renewable energy source to meet the targets of the group’s global ESG strategy, but the roof was ruled out by the process equipment installed on it, insufficient load capacity and strict fire safety requirements. We delivered two systems with a combined capacity of 100 kWp on a carport over a row of 24 parking spaces, with EV charging stations. The structures were designed for heavy traffic, so the car park remains fully usable, including by the lorries serving the plant. The roof was left untouched, and fire separation distances and compliance with the local zoning plan (MPZP) were maintained.
We completed a ground-mounted PV system at Neuca’s headquarters. A new carport project of approximately 671 kWp is under construction. The photograph shows the site and its existing infrastructure.

Are grants or financing available for businesses in Poland?
Eligibility depends on the company, region, project and the current programme rules. We assess Polish and EU funding options as part of the investment case and check current official sources before recommending an application. We do not assume that funding is available to every business.
How should we choose a solar PV contractor?
Look for projects at comparable sites, an in-house design team, qualified site managers and a clear service scope. Compare assumptions, responsibilities, acceptance criteria and maintenance plans as well as the price per kWp. A supplier ranking cannot assess your site for you.
Do you install PV on production and warehouse buildings?
Yes. Our projects range from 50 kWp to more than 1 MWp, including a 604 kWp installation on a warehouse with a cold store in Niepruszewo. We assess roof load capacity, covering and warranty conditions before design, and coordinate installation with the maintenance team.
What PV capacity is right for our company?
We size the system to your actual consumption profile, not to the roof area or the energy bill alone. When a large system would give low self-consumption, we first look at adding battery storage and only then at a smaller system. With battery storage, or with capacity matched to the profile, self-consumption can reach 70–90%, but we confirm this against your site’s 15-minute load profile.
How do you take the building insurer’s requirements into account?
Before design work starts, we check the requirements for fire protection, equipment location, inspections and the documentation needed to discuss the policy, and agree technical solutions for the site. The insurer sets the final terms of cover and the premium.
How can we be sure the production and savings forecast is not overstated?
The forecast has to follow from the 15-minute load profile, actual self-consumption, the tariff, technical conditions, grid connection limits and stated assumptions. After commissioning, results should be monitored and any deviations discussed on the basis of data, not claims.
How long does a commercial PV project take?
For systems above 50 kWp, the full process (installation, grid connection and commissioning) usually takes approx. 6–12 months. The schedule depends on the site, grid connection, approvals and scope; projects with battery energy storage (BESS) may need more time.
What happens after commissioning?
We agree the O&M scope for each installation. It can include monitoring, inspections, thermal imaging, electrical testing and rules for responding to performance deviations. We can also maintain systems built by other companies after a condition audit, a documentation review and the necessary electrical tests.
Can the investment be financed without using our own capital?
We work with financing partners and help you compare six models: a power purchase agreement (PPA), a virtual PPA (vPPA), PV as a service (PVaaS), an energy service company (ESCO) contract, subscription and leasing. The choice depends on your balance sheet, debt policy, the scope of the investment and the financing partner’s terms.
What does EPC delivery mean?
EPC brings design, procurement and construction together under one contract. The scope covers approvals, installation, commissioning and acceptance documentation. We agree responsibilities for each stage and the terms of ongoing maintenance before work starts.
