15 kW Three-Phase System

15 kW three-phase solar kit for large homes and high consumption

This 15 kW three-phase solar kit is designed for large villas, high-consumption households and small businesses with an annual electricity use of roughly 9,000 to 16,000 kWh. In Spain it generates around 24,750 kWh per year — up to about 105 kWh on a clear summer day — covering a large share of your daytime demand and cutting a substantial part of your electricity bill from day one.

Growatt MID 15KTL3-XH: a three-phase hybrid inverter

The kit is built around the Growatt MID 15KTL3-XH, a three-phase hybrid inverter sized for homes and premises with a three-phase supply. It balances the load across all three phases, handles a 15 kW array comfortably and is battery-ready: you can add storage later without replacing any equipment. Production is monitored in real time from the Growatt app.

30 Tensite 500 W TOPCon N-Type panels — 15 kWp

The system mounts 30 Tensite 500 W solar panels with latest-generation TOPCon N-Type cells: higher efficiency, better performance in diffuse light and at high temperatures, and excellent long-term durability. Together they deliver 15 kWp of peak power to make the most of every hour of sunlight.

Battery-ready: add storage whenever you want

Because the MID inverter is a hybrid, this kit is fully prepared for batteries. Start with self-consumption today and add storage when it suits you — to use your surplus daytime energy at night and keep essential circuits running during a power cut. No rewiring, no inverter swap.

Professional installation, legalization and IVA included

The price is closed, with no surprises: it includes professional installation, the mounting structure and wiring, system legalization and commissioning across Spain, and IVA. We handle all the paperwork so you can simply start saving.

Is the 15 kW solar kit right for you?

It is the ideal choice if you live in a large home or villa with high consumption, run a small business on a three-phase supply, or want headroom to add an EV charger and a battery later. If your consumption is lower, take a look at our 10 kW and 12 kW kits; if it is higher, contact us for a tailored design.
