02 · Conversion

Inverters for your home

Our main inverter brands are Hinen, Deye, Solis and Solplanet. We select the model based on the grid connection, PV array power, compatible battery and required backup functions.

Fronius, Austria: a premium choice, supported locally by Nectaria's service partnership. Huawei: an established ecosystem with strong integration.

Hinen, direct imports: strong value for money and an integrated ecosystem, with battery management systems (BMS), battery packs, inverters and storage systems developed and manufactured in-house.

Victron: for off-grid systems and configurations designed for energy autonomy. Deye: hybrid inverters for solar generation and storage.

Solis: grid-connected and hybrid ranges. Solplanet: power conversion and battery integration in hybrid systems. We select the model based on the electrical connection, power requirements and panel orientation; backup functionality depends on the model, battery and electrical design.

As part of Nectaria's standard offer: a 10-year warranty on selected Hinen, Deye and Solis inverters and Hinen, Deye and Dyness batteries, per the warranty certificate of the delivered model. Installation, connection and operating conditions, together with performance limits, must be checked in the certificate.

03 · Storage

Residential batteries

We work with Hinen, Deye, Dyness, BYD, Huawei and Solplanet to store energy for use in the evening. Usable capacity, power and inverter compatibility are checked for each configuration; backup requires the appropriate equipment and circuits.

Compare models, warranties and technical conditions →Explore all panel, inverter and battery brands →

04 · DC cable runs

Premium 6 mm² solar cable

We use premium 6 mm² solar cable for direct-current (DC) runs where appropriate for the project. Cables are secured and protected according to their exposure and mechanical loads.

Final sizing is determined for each circuit, taking account of current, length, voltage drop and installation conditions.

05 · Connections

Original Stäubli MC4 connectors

We use original Stäubli MC4 connectors and mating pairs with manufacturer-documented compatibility, correctly crimped using the appropriate tools.

An “MC4-compatible” label on another brand's connector does not establish that the pairing is suitable. We check the connector pair at every connection.

06 · Mounting

Directly imported mounting structures

We import mounting structures directly and have used them in Nectaria projects for four years, across different roofs and configurations.

For roofs, we use aluminium structures manufactured in Poland; for ground installations, galvanised steel structures manufactured in Poland or Romania. Fixings and anchoring are selected for the supporting surface, wind and snow loads. Ground mounting without concrete is possible where ground conditions and the design allow it.

07 · Protection

Protection panels with components from established brands

We use identifiable, documented components from established brands. Manufacturing origin is checked for the selected product.

AC/DC protection devices, surge protective devices (SPDs) and isolators are selected to suit the project's electrical configuration.

The right configuration starts with the project, not the product.

We start with consumption, site conditions, future expansion and backup needs, then choose the right technical and financial combination.

Efficient installation · careful workmanship

Installation in one day. Care at every step.

For residential systems of 3–12 kW, on-site installation normally takes one day after technical validation and site preparation. This can reduce the time you need to set aside for the work.

≈ 6 daysindicative timing for 500 kW

For larger systems, timing depends on capacity and complexity. As a guide, on-site installation of a 500 kW system takes around six days, followed by mandatory testing and commissioning in the days immediately afterwards.

Severalsystems on the same day

Nectaria has the team capacity to install several residential PV systems on the same day and can arrange installation promptly for contracts signed in the coming period.

≈ 90%standard equipment held in stock

In approximately 90% of cases, panels, inverters, batteries and standard mounting structures are already in stock.

The right mounting structure

Designed for the roof.

If a roof requires a special mounting structure, we order it for that specific project rather than adapting a standard solution on site.

An essential detail

Original Stäubli MC4 connectors.

Connectors are a small part of the overall cost but matter to system safety and quality. We select them with the same care as the main equipment.

Preparation, stock and team capacity support fast installation. Quality depends on every technical decision.

Benefits of Solar Panels for Your Home

Solar Energy at Home

Generating electricity from sunlight can reduce your reliance on conventional electricity supplies and your home's carbon footprint.

Potential Long-Term Savings

Producing electricity at home can reduce energy bills. Where the applicable prosumer arrangements allow, surplus can be exported to the grid. Actual savings and export revenue depend on consumption, generation, tariffs and contractual terms.

Potential Property Value

Solar panels may make a home more attractive to buyers seeking renewable energy and lower running costs. The effect depends on the property and installation.

Community Benefits

Residential solar can support wider adoption of renewable energy and encourage communities to use energy more responsibly.

Installing and Integrating Residential Solar

Feasibility Assessment

Before installation, we assess the project's feasibility. Orientation, roof pitch and sunlight exposure affect system performance and must be considered in the design.

Installation and Configuration

Installation follows assessment and includes the mounting structure, panels and connection to the home's electrical system. The layout is selected for available sunlight and site constraints.

Maintenance and System Improvement

Routine Maintenance

Solar panels require relatively little maintenance. Periodic inspections and cleaning where necessary help identify problems and maintain performance.

Upgrades and Extensions

A system may be extended or upgraded as needs change. Battery storage and other compatible components can support greater self-consumption, subject to checks of the existing installation.

A well-designed residential PV system provides renewable electricity and can reduce grid dependence and energy costs. We help assess the configuration against your home, consumption and long-term plans.

FAQ

Equipment and warranty questions

Available brands, warranty conditions and choosing a battery for your home.

Which inverter and battery brands does Nectaria offer?+

Our main inverter brands are Hinen, Deye, Solis and Solplanet. We select the model based on the grid connection, PV array power, compatible battery and required backup functions. Our storage options include Hinen, Deye and Dyness. Depending on the project, our full portfolio also includes Fronius, Huawei, Victron, BYD and Solplanet batteries.

What warranty does Nectaria offer on inverters and batteries?+

What do Tier 1 and 3rd place mean for Solis?+

Solis is included in BloombergNEF's Tier 1 list, according to the manufacturer's Q1 2025 announcement. Globally, Solis ranked 3rd by PV inverter shipments in 2024, according to Wood Mackenzie's market share report. Third place refers to 2024 shipments, not a general quality ranking or all subsequent rankings.

Does the 10-year warranty automatically cover the stated battery cycle count?+

Declared technical cycle life: Hinen B8900M-HA — 8,000 cycles; Deye SE-G5.1 Pro-B — ≥6,000; Dyness PowerBrick 14.336 kWh — ≥8,000. These figures depend on the model and test conditions; they are not a cycle count guaranteed by the 10-year warranty. The performance warranty may have total energy throughput and remaining-capacity limits, as specified in the certificate. Brand, warranty and cycle count do not guarantee AFM eligibility; we assess every project.

Our approach

A good system starts with generation matched to consumption, careful installation and service that remains available.
