Solar panels for your home: price, installation and real savings
Install solar panels for self-consumption and reduce your bill from day one. We calculate the price, the payback period and the optimal configuration (with or without battery) depending on your energy consumption and the type of roof.
From sunlight to your home: how solar panels work
The panels capture sunlight and convert it into electricity. A solar inverter adapts it so that any appliance in your house can use it directly. What you don't consume at the moment you can store in a battery or dump it on the grid. That's how simple solar self-consumption works.
High quality panels
We install the best panels on the market: high performance, long lifespan.
They work even if it's cloudy
The panels continue to generate on cloudy days or with low temperatures. Designed for the Spanish climate.
Optimized for your space
More production per square meter, with a compact and efficient design adapted to your roof.
30-year warranty on panels
The longest warranty in the industry, both in terms of product and energy production. The competition offers 3 years.
Why install solar panels in your house?
Lower your electricity bill from the first month
The energy you produce is energy you don't pay for. With a well-sized installation, the estimated savings are very high.
Protection against blackouts and price increases
With a battery, your home continues to work when the network fails. And when electricity prices rise, you no longer depend on them.
Increase the value of your home
A house with solar panels installed is worth more. It is a permanent improvement that stays in the property and attracts buyers.
An investment that pays for itself
The average amortization period in Spain is 6 to 9 years. The panels last 30. The rest is pure savings.
Trusted by industry leaders
A battery multiplies what solar panels can do, but it's not always essential
You consume most of your energy in the afternoon or at night
Do you want to reduce your dependence on the electricity grid
You want protection against rising electricity prices
You need security against blackouts (with the right system)
You already consume a lot of energy during the hours of sunshine
You want to minimize your initial investment
Your total consumption is low
The return of the battery would be slower for your consumption profile
To maintain power during a power outage, panels and battery alone are not enough. Most grid-connected systems also need a backup switch (ATS) and a critical load circuit. We value it in your free study.
Ways to lower your electricity bill forever.
And what you recover.
The price of a solar installation depends on much more than the number of plates. A realistic budget takes into account your consumption, roof conditions and component quality. The most useful approach is a turnkey budget: a complete solution, from panels to electrical protections, ready to operate safely from day one.
Energy consumption and household habits
A single-family home that consumes mainly during the day has a very different optimal configuration than one with high consumption at night.
Roof orientation and inclination
A favorable orientation and an appropriate inclination improve production.
Shadows and Obstacles
Fireplaces, trees or nearby buildings can reduce production if not properly designed.
Type and condition of the roof
The structure, materials and access all influence the complexity of the assembly.
Quality of the components
Panels, inverter, structure and electrical protections make differences in performance, durability and guarantees.
Solar battery (if applicable)
Incorporating storage increases the use of your energy, but it also increases your initial investment.
How much can you save per year with solar panels
Actual savings depend on how much energy you produce and how much of that energy you consume directly. The greater the self-consumption, the greater the return. If you generate more than you use, the excess can be offset on your bill through the simplified compensation system.
Grants and tax benefits for solar panels
Depending on your autonomous community, municipal grants and rebates from the IBI can significantly reduce the initial cost. The conditions vary by region and are updated frequently. We advise you on the grants available in your area as part of your free study.
Monitor everything, from anywhere
24/7 monitoring
Monitor your installation at all times and follow its performance constantly, wherever you are.
Battery Management
Decide how you want to use your battery, depending on what you need at any given time.
All in one app
Manage inverter and battery from a single platform, compatible with Android and iOS and easy to use.

Questions?
We have the answers.
The lifespan of the solar panels we work with is more than 30 years, but Eltex offers a triple warranty of 35 years.
The answer is yes. Current solar panels do not need direct radiation to produce energy; they work perfectly with diffuse radiation, that is, when there are clouds or bad weather.
Maintenance of solar panels is easy and requires very little intervention. They are designed to withstand normal weather conditions, so occasional cleaning and checking for visible damage or performance loss is enough. In most cases, you can handle the basic care yourself without complications.
The sun's rays on the photovoltaic cells that make up a solar panel produce an exchange of electrons between the different layers of the photovoltaic cells. This movement is what generates direct current, which must be converted to alternating current to be used in homes.
Installing solar panels allows households to save up to 70% on their electricity bill, which has led thousands of families in Spain to opt for self-consumption. This type of energy not only provides energy independence, but also increases the value of the home, helps reduce polluting emissions and gives access to subsidies and tax benefits to make adoption easier.
