Off Grid Possibility

Off-Grid (Self-Sufficient)

This is an available upgrade. Your Mila villa creates and manages its own resources, independent of any main connections.

  • How it works: The mila villa uses systems like solar panels (for power), water tanks (to collect rain), and contained waste treatment systems. It gathers and manages everything it needs by itself.
  • Who sets it up: Mila Villa designs and installs the complete system (solar roof, battery and inverter) as part of the off-grid package.
  • Best for: Remote properties, nature spots, or anyone who wants complete energy independence.


Solar & battery package (2-bedroom unit):

  • Integrated solar roof: Midsummer SLIM thin-film panels (CIGS), bonded directly onto the Lysaght steel roof. No frames, rails or roof penetrations; 2 mm thin and 2.8 kg/m²
  • Approx. 6 kWp on approx. 55 m² of roof
  • 15.3 kWh LiFePO4 battery storage (6,000-cycle rated)
  • Approx. 9,000–10,000 kWh per year, depending on roof orientation and pitch
  • Hybrid inverter with a remote monitoring app to track your energy production and savings
  • Panels: 25-year product warranty, 80% power guarantee after 25 years; IEC 61215 / IEC 61730 certified, fire class BROOF(t2)
  • Saves approximately 7,500 kg of CO2 emissions per year

Made in Indonesia: the SLIM panels are planned to be produced in Indonesia from 2027 by PT Metalogika, in a joint venture with Midsummer (Sweden).

Insulation: Fully insulated walls and roof.

Frequently asked questions

Which Mila models can run off-grid?

All of them: Mila Resort, Mila Modular and Mila Eco.

How much power does the system produce?

For a 2-bedroom villa, about 6 kWp of thin-film solar on the roof gives roughly 9,000–10,000 kWh per year, depending on orientation and roof pitch. A 15.3 kWh battery stores power for the evening and night.

Why thin-film panels instead of standard solar panels?

The Midsummer SLIM panels are 2 mm thin and bonded directly onto the steel roof: no frames, rails or roof penetrations, and they weigh 2.8 kg/m².

What about water and waste?

Rainwater collection with storage tanks and a contained waste-treatment system can be added, so the villa needs no mains connections.

Who installs and maintains the system?

Mila Villa designs and installs the complete system: solar roof, battery and inverter. The hybrid inverter comes with an app to monitor production.
