Install solar panels on your home and stop paying for the electricity that the sun provides for free

At Davofrío, we approach residential photovoltaic engineering differently. Before talking about panels, we calculate. Because if your installation is not adapted to what you actually consume, you are simply adding another expense without knowing if you will ever amortize it.

Most solar panel quotes are useless to you

You've seen your electricity bill this month. And last month. And the month before. And every time you open it, you think the same thing: you have to do something.

What happens next is usually the same in almost every case. You ask for quotes. You receive three PDFs with different numbers, rows of panels, and brands you don't know. Nobody has asked you how your heating system is set up. Nobody has gone up to your roof. And you still don't know which installation actually makes sense for your home.

Most installers calculate how many panels you need by looking at your average electricity bill

The solar market trap

We understand what it means to spend weeks looking at quotes and still feel just as lost

We have spoken with many homeowners who came to us after going through that process, and the feeling is always similar. You want to take the step, your bill is practically begging you to, but you don't quite trust it because nobody has given you an explanation that makes real technical sense.

This happens because the residential solar market quickly became flooded with companies that sell panels the same way they sell household appliances, with a price, a factory warranty, and little else.

The sale of photovoltaic panels has been taken over by salespeople instead of experts in climate control and energy solutions, based on a utility bill rather than the reality of families.

But then, when something fails, or when the production isn't what was promised, there isn't an engineer behind it who understands why.

We come from the opposite side. We are climate control engineers who have incorporated photovoltaic solutions into our services because it makes technical and economic sense to do so when you already know how a home consumes energy from the inside. Not the other way around.

The problem with most solar panel quotes you will receive

Many numbers, little explanation

In recent years, every time a client talks to us about photovoltaics, they tell us the same story. Installers who send quotes, all with a different number of panels and costs, but none of them have been able to explain why that is the best solution.

Under-dimensioned installations

If you have air conditioning, a heat pump, or heating—or are thinking of adding them—your actual consumption in some months can double the average, and a deficient installation leaves you dependent on the electric company and paying when power is at its most expensive.

Over-dimensioned installations

The other extreme isn't the solution either. An over-dimensioned installation produces energy that you don't consume, which you feed back into the grid at a bargain price, and which can cause you to take 2 to 4 years longer to pay it off compared to what you were promised.

The best photovoltaic installation is the one dimensioned with your life and your family's needs in mind.

The advantages of photovoltaic energy when combined with climate control engineering

Real dimensioning based on your actual consumption, not your average bill.

Before proposing any number of panels, we analyze your consumption hour by hour and cross-reference it with the actual electrical loads of your home: climate control, hot water, and household appliances. If you have or plan to have aerothermal energy, a heat pump, or an electric vehicle charger, we incorporate it into the calculation from the very beginning.

The result is an installation that produces what you are going to consume when you need it most, not an average installation for an average house that doesn't exist.

The same company that installs the panels maintains your home's climate control.

At Davofrío, we are experts in integrating photovoltaics with your existing or planned climate control system. If you have an aerothermal system, the surplus can be diverted to domestic hot water instead of being fed back into the grid at a minimum price. If you have an energy management system, we connect it.

They aren't independent projects, it's your home. And we treat it as a single system designed so that every kilowatt produced by your roof is maximized inside your house.

Real payback, not brochure payback.

The typical payback period under current self-consumption conditions and available subsidies ranges between 5 and 7 years. However, this range is only achieved if the dimensioning is correct and the installation is integrated with the home's actual consumption.

In our preliminary technical study, we show you the estimated annual production, the projected savings, and the payback period calculated based on your data—not on a generic case, but in your home—so that you have the data needed to make the best decision.

The process that turns your home's roof into your own power plant

01 Home energy audit.

We analyze your electric bill, your hourly consumption profile, the roof's orientation and tilt, existing shadows, and the installed or planned climate control system. With this data, we calculate the estimated monthly production and compare it with your actual demand.

02 Custom installation design.

We select the number of panels, the inverter power, and the installation configuration based on the calculations, not the catalog. If there is a possibility for integration with a storage battery or with the climate control system to maximize self-consumption, we present it to you with the real numbers on the table.

03 Installation with engineering standards.

Our technicians are trained in industrial environments where there is no margin for error. We apply that culture of precision to every residential installation: mountings calculated for the wind load in your area, correct wiring, and performance tests before delivery. Nothing is improvised.

04 Legalization, grid connection, and monitoring.

We manage all procedures with the distribution company and the administration so that the system is legally registered and you can access surplus compensation from day one. After the installation, we explain how to read the production and consumption data so that you have real control over what is happening on your roof.

At Davofrío, we send a technician with calculation software and the right questions.

The electricity bill that stops being a problem—the true goal

Peace of mind doesn't come from having panels on the roof.

Beyond the savings in euros, what clients tell us after installation is very similar.

That they have stopped thinking about the electric bill. That in summer they turn on the air conditioning without looking at the clock. That in winter the heating is running and they know that a good part of that energy comes from the roof.

Having this peace of mind comes from having an installation that produces what it was calculated to produce, integrated with the home's system, and backed by a technical team that is still there if anything needs adjustment.

That is what Davofrío designs. We do not just install solar panels. We design energy independence systems based on engineering and calculations.

Do you need a photovoltaic installation for your home?

If you have or are thinking about installing aerothermal systems, a heat pump, or high-power climate control at home, and you want the photovoltaics to be designed to work with that consumption from the very beginning.

Or if you already have panels installed that are not performing as promised and you want to know why, you need a company that can respond when something does not work as calculated—without redirecting you to the panel manufacturer or the inverter installer.

If you are looking for the cheapest quote on the market, we are not the right choice. If you are looking for an installation that truly gives you back what you invest within the promised timeframe, you are in the right place.

You need a company that knows your home's entire system, not just the roof.

Official TAS: Technical warranty from the best brands

Very few climate control engineering companies are official Technical Assistance Services. Even fewer are experts at coordinating photovoltaics with the rest of your climate control systems.

At Davofrío, we are the Official Technical Assistance Service (TAS) for the market-leading brands that combine with photovoltaics.

Brands like Airzone, Daikin, Mitsubishi, and Panasonic train our technicians and engineers to achieve the maximum performance from their climate control systems in combination with photovoltaic systems.
