8 kW solar kit: production, savings and payback

A 8 kW solar kit produces about 13,200 kWh of electricity a year and saves roughly €1,270–1,720 on your bill. Installed turnkey from €6,919 with legalisation included, it pays for itself in around 4.4 years and keeps producing for 25+ years.

At today's electricity prices a 8 kW system covers a large share of a typical home's consumption, for a saving of about €1,270–1,720 per year in direct self-consumption. On a turnkey price of €6,919 that is a payback of roughly 4.4 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 8 kW kit suits a home using roughly 280–746 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

8 kW three‑phase solar kit for large villas and small businesses

The 8 kW three‑phase solar kit is aimed at large villas, high‑consumption homes and small businesses that want to get very close to full coverage of their electricity demand.

With 16 panels rated at 500 W and an 8 kW three‑phase inverter, it delivers very high production and a balanced distribution across phases, ideal for installations with many loads.

Why this system?

For target consumption between roughly 280 and 746 kWh per month, the 8 kW three‑phase kit can cover a very high share of yearly usage, often generating surplus that can be stored or compensated.

It is a strong choice for large homes with pool, extensive air conditioning and many appliances, as well as for small businesses that want to cut the variable part of their bill almost to zero.

Thanks to its three‑phase design, it integrates well with complex electrical boards and makes it easy to add batteries or expand the system later.

Estimated production and savings

Estimated annual production for this 8 kW solar kit is about 13,200 kWh, which in many scenarios allows the installation to approach 100 % coverage when major loads are scheduled in solar hours.

Components included

The kit includes 16 Tensite 500W TOPCon N‑Type modules, totalling 8 kW of peak power. Their high efficiency and reliability make them suitable for large residential arrays and small commercial rooftops.

The inverter is a Growatt MOD 8000TL3-XH 8 kW three‑phase unit that manages this generator and distributes power across the three phases efficiently. It offers monitoring and is ready to integrate with storage solutions.

The package includes mounting structure for 16 panels, wiring and basic protections so Enera Solar can build, legalise and commission the system according to Spanish regulations.

Frequently Asked Questions

How much does a 8 kW solar kit cost installed?

From €6,919, 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 8 kW kit save per year?

About €1,270–1,720 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 4.4 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 8 kW system produce?

About 13,200 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.

What type of installation is the 8 kW 3‑phase solar kit suitable for?

It is suitable for large villas, high‑consumption homes and small businesses with monthly usage between about 280 and 746 kWh.

How much energy does an 8 kW solar kit produce per year?

Estimated annual production is around 13,200 kWh (8 kWp × ~1,650 kWh/kWp), with good orientation, tilt and typical Spanish solar conditions.

Can an 8 kW solar kit cover nearly 100 % of my consumption?

In many cases it can get very close to full coverage, especially when large loads are shifted to solar hours and storage or surplus compensation is used effectively.

Can I combine the 8 kW kit with batteries?

Yes, the three‑phase Growatt inverter is designed to work with compatible storage solutions so you can store surplus and increase self‑sufficiency.

Do I need three‑phase supply for this kit?

Yes, this kit is intended for three‑phase connections. If your supply is single‑phase, a different configuration or a grid upgrade would be needed.
