Villas and holiday homes
Pool, air conditioning and guests. Your own energy by day, battery at night and backup if the power goes out.
Solar + battery self-consumption · Villas and hotels
Solar power for villas and hotels.
Lower bills. No more blackouts.
We design and install solar panels with batteries for villas, hotels and holiday rentals. Produce your own energy, cut your bill from the first month and keep everything running even when the grid fails.

Who it's for
For places that can't afford to go dark
Wherever there is sun, expensive electricity or an unreliable grid, a solar system with a battery pays for itself.
Hotels and boutique resorts
A hotel uses the most energy just when the sun shines brightest: cooling, kitchen, laundry and pool. Every solar kWh is a kWh you don't buy.
Holiday rentals and glamping
Bungalows, guesthouses and small complexes, with every unit's energy managed from your phone.
What you get
Lower bills, zero blackouts and happier guests
Lower bills
You produce your own energy and buy less from the grid, especially at expensive hours. You'll see it from the first month.
No blackouts
If the grid goes down, the battery keeps what matters running: cooling, fridges, wifi, water pumps and security. Your guests won't even notice.
Silent, no diesel
Fewer generator hours: no noise, no fumes and no waiting for fuel to arrive.
More value, better reviews
A sustainable property rents better, improves its energy rating and scores points in green certifications.
Our systems
A system sized for every property
Solar panels, hybrid inverter, LFP lithium battery and monitoring on your phone. From a two-bedroom villa to a hundred-room hotel.

How we work
From your bill to a working system, in four steps
- 01
Send us your bill
An electricity bill, a few photos of the roof and the number of rooms are enough to get started.
- 02
Free study
We simulate a full year, hour by hour, and give you clear numbers: investment, annual savings and payback.
- 03
Turnkey installation
We supply the equipment and coordinate installation with certified installers, permits and grid connection.
- 04
Follow-up
Monitoring on your phone and technical support after commissioning.
We also do
Energy consulting for businesses and investors
Behind every villa is the same engineering we apply to utility-scale solar and battery projects across Europe.
Studies for commercial & industrial clients (C&I)
Consumption analysis, PV and battery sizing, peak shaving and return on investment.
Grid-scale PV and BESS projects
Development, engineering, RFPs, manufacturer evaluation and EPC and LTSA contracts for developers and investors.
Publications
Thoughts on the energy transition
Articles on energy, electricity markets, storage and other topics we find interesting.
Energy transitionSelf-consumption
Fuel crisis: what if the answer is on the roof?
The Saudi crude cut to Europe has sent diesel and petrol prices soaring. A delivery-van example shows how much oil dependence costs and what role solar, batteries and electrification can play.
Villas & hotelsSelf-consumption
Bali runs dry: lessons from an island that depends on a ship
Eight-hour queues, odd-even rationing and closed schools. Bali's October 2026 fuel crisis shows what happens when all energy arrives on a tanker, and what a villa with solar and storage can do about it.
Electricity marketStorage
What are the main challenges of the energy transition?
Spain produces more and more renewable energy, but producing a lot is not enough. Prices that collapse at midday, wasted energy and a grid that has to adapt: the challenges of the next phase.
About Ingrenov
Utility-scale engineering, working for your property
Ingrenov was founded on European expertise in solar energy and battery storage. Based in Spain, we have worked on projects in Spain, Portugal, France, Italy and Germany, from industrial plants to grid-scale batteries.
We bring the same rigour to villas and hotels: every system is sized with your real consumption and our own hour-by-hour simulation tools, and built with tier-1 equipment.
One point of contact, clear answers and every number on the table. Your property, on its own energy.
