6 kW solar kit: production, savings and payback
A 6 kW solar kit produces about 9,900 kWh of electricity a year and saves roughly €950–1,290 on your bill. Installed turnkey from €5,528 with legalisation included, it pays for itself in around 4.7 years and keeps producing for 25+ years.
At today's electricity prices a 6 kW system covers a large share of a typical home's consumption, for a saving of about €950–1,290 per year in direct self-consumption. On a turnkey price of €5,528 that is a payback of roughly 4.7 years; adding a battery raises self-consumption further and shortens it. After payback you keep more than two decades of near-free electricity.
The turnkey price has no hidden extras: it covers the solar panels, inverter, mounting structure and installation, the technical documentation, and the legalisation with the town hall and the electricity company — including the switch to a self-consumption contract. We hand it over working and registered, with no paperwork for you to chase.
A 6 kW kit suits a home using roughly 210–560 kWh per month. If your supply is three-phase, ask about the three-phase version; if your goal is full independence from the grid, look at the off-grid kits. The system can be expanded later with lithium battery storage.
About this product
6 kW three‑phase solar kit for villas and rural homes
This 6 kW three‑phase solar kit is designed for properties with three‑phase supply, such as villas, rural homes and small farms with higher contracted power. It delivers the same production as the 6 kW single‑phase kit but distributes it across three phases.
It is a strong option for sites with pumps, motors or other three‑phase loads, while keeping a robust PV power level for self‑consumption.
Why this system?
If you already have a three‑phase connection and monthly usage between about 210 and 560 kWh, this kit lets you make full use of the existing meter and wiring without converting back to single‑phase.
Compared with the 6 kW single‑phase kit, the main advantage is compatibility with three‑phase infrastructure, which is common in villas, large rural houses and properties with pumps or machinery.
Three‑phase configuration also makes future power increases easier, whether by adding more panels or moving to a larger inverter in the same family.
Estimated production and savings
The estimated annual production of this 6 kW three‑phase kit is also about 9,900 kWh, identical to the single‑phase version because they share the same number of panels and peak power. The difference lies in how that energy is delivered across the three phases.
Components included
The kit includes 12 Tensite 500W TOPCon N‑Type panels, providing 6 kW of peak power, with the same efficiency and durability characteristics as the single‑phase version.
The inverter is a Growatt MOD 6000TL3-XH three‑phase 6 kW model, purpose‑built for three‑phase self‑consumption installations. It can monitor production per phase and is well suited to homes and small farms with three‑phase loads.
The package includes mounting structure for 12 panels, wiring and basic protections so Enera Solar can build, legalise and commission the system according to local regulations.

Frequently Asked Questions
How much does a 6 kW solar kit cost installed?
From €5,528, turnkey — panels, inverter, mounting, installation and the legalisation and contract change are all included. You get a closed price up front, with no surprises on the day of installation.
How much does a 6 kW kit save per year?
About €950–1,290 a year in direct self-consumption at current electricity prices. Adding a battery increases the saving because you also use your own solar energy at night.
How long until it pays for itself?
Around 4.7 years at the current price and electricity tariff, after which the system keeps producing for 25+ years. Available subsidies and the IRPF deduction can shorten the payback further.
How much electricity does a 6 kW system produce?
About 9,900 kWh per year in Spain, depending on roof orientation, tilt and shading. That is the figure used for the production and savings shown on this page.
When should I choose a 6 kW three‑phase solar kit instead of a single‑phase one?
If your property already has three‑phase supply or uses three‑phase pumps and motors, the 6 kW three‑phase kit integrates better and spreads production across all phases.
Does the 6 kW three‑phase kit produce the same as the single‑phase version?
Estimated annual production is around 9,900 kWh (6 kWp × ~1,650 kWh/kWp), with good orientation, tilt and typical Spanish solar conditions.
What type of property is the 6 kW 3‑phase solar kit suitable for?
It is ideal for villas, rural houses and small farms with three‑phase supply and monthly consumption between about 210 and 560 kWh.
What savings can I expect from the 6 kW three‑phase kit?
At ~€0.19/kWh including VAT, annual savings range from ~€1,123 with average self-consumption to ~€1,917 if you use almost all the energy, paying back in ~2.8–4.7 years. Use the configurator for the exact figure for your consumption and battery choice.
Can the 6 kW three‑phase kit be expanded later?
Yes, three‑phase topology makes expansions easier, either by adding more panels if the inverter allows it or by upgrading to a larger three‑phase inverter.
