10 kW 3-Phase System
10 kW 3‑phase solar kit for farmhouses, rural homes and agritourism. 20× Tensite 500W panels and Growatt MOD 10000TL3-XH for very high self‑sufficiency. Installed for you — not a DIY-only kit.
Ideal for a consumption of ~350–933 kWh/month.
Payback assumes ~40% self-consumption; the surplus is compensated at the export price, with 3% annual electricity price growth.

10 kW solar kit: production, savings and payback
A 10 kW solar kit produces about 16,500 kWh of electricity a year and saves roughly €1,590–2,150 on your bill. Installed turnkey from €8,233 with legalisation included, it pays for itself in around 4.2 years and keeps producing for 25+ years.
At today's electricity prices a 10 kW system covers a large share of a typical home's consumption, for a saving of about €1,590–2,150 per year in direct self-consumption. On a turnkey price of €8,233 that is a payback of roughly 4.2 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 10 kW kit suits a home using roughly 350–933 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
10 kW three‑phase solar kit for maximum self‑sufficiency
The 10 kW three‑phase solar kit is designed for large homes, farmhouses and rural tourism properties that want to get as close as possible to energy self‑sufficiency.
With 20 panels rated at 500 W and a 10 kW three‑phase inverter, it delivers very high production and is ideal for sites with many appliances, HVAC systems and potentially professional uses.
Why this system?
For target consumption between about 350 and 933 kWh per month, the 10 kW kit can cover the vast majority of yearly usage, especially when loads are optimised for solar hours.
It is particularly well suited to rural houses with several guests, agricultural properties with a residential part and agritourism businesses that see high occupancy.
Combined with batteries, this size makes it possible to bring the electricity bill very close to zero by using a mix of direct self‑consumption, storage and export compensation.
Estimated production and savings
Estimated annual production for this 10 kW system is about 16,500 kWh, making it one of the most powerful options in the residential and light commercial range.
Components included
The kit includes 20 Tensite 500W TOPCon N‑Type modules, providing 10 kW of peak PV power. This configuration is suitable for large roofs on farmhouses, rural homes or small commercial buildings.
The inverter is a Growatt MOD 10000TL3-XH 10 kW three‑phase unit, capable of handling large energy flows and acting as the core of a system with storage and three‑phase loads.
The package also includes mounting structure for 20 panels, wiring and basic protections; Enera Solar can complement this package with additional protection devices and batteries for a more advanced solution.

Frequently Asked Questions
How much does a 10 kW solar kit cost installed?
From €8,233, 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 10 kW kit save per year?
About €1,590–2,150 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 4.2 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 10 kW system produce?
About 16,500 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.
Which installations benefit most from the 10 kW 3‑phase solar kit?
Large homes, farmhouses, rural houses and agritourism businesses with monthly consumption between about 350 and 933 kWh and sufficient roof space.
How much energy does a 10 kW solar kit produce annually?
Estimated annual production is around 16,500 kWh (10 kWp × ~1,650 kWh/kWp), with good orientation, tilt and typical Spanish solar conditions.
Can a 10 kW solar system bring my bill close to zero?
In many cases, by combining direct self‑consumption, surplus compensation and suitable battery storage, the variable part of the bill can be reduced almost to zero.
Do I need three‑phase supply for this kit?
Yes, this kit is designed for three‑phase connections. Large properties with high contracted power commonly use three phases to balance loads.
Can I add batteries to the 10 kW three‑phase kit?
Yes, the Growatt three‑phase inverter is prepared to work with compatible storage solutions, increasing self‑sufficiency and making better use of surplus.
