If you are thinking about betting on green energy and reducing your electricity bill, installing solar panels may be the best way for you. As David Alonso, CEO of Isla Solar, a company dedicated to the installation of solar panels with more than 18 years of experience in the sector, highlights: “We are in one of the best times for solar self-consumption, since installations have become cheaper after the fever experienced in recent years.” Thus, quality and sustainability are two of the firm commitments of this company, who by installing solar panels will help you contribute to caring for the environment and save on your next bills. Next, in Evidence Network, we explain how to install solar panels, how much it costs and its profitability to benefit from them, whether it is in your home, your business or another space.
How to install solar panels
Betting on self-consumption means investing in installing photovoltaic panels and, for this, both planning and execution through specialized companies are necessary. But how is this process carried out? This is the step by step:
- Study: In a first phase, the location, orientation and characteristics of the installation space are evaluated. The study is essential to know the consumption, the customer’s needs and size the assembly.
- Technical design and budget: The number of solar panels and other elements, such as batteries, are defined to present a budget.
- Legal procedures and permits: Municipal permits, building licenses or subsidy applications are managed.
- Installation of solar panels: With all permits approved, solar panel installers can now proceed.
- Operation verification: By connecting the panels to the inverter and the home’s electrical system, their correct operation will be verified.
- Maintenance: After installation, it is recommended to carry out periodic maintenance to guarantee maximum and optimal performance of the installation.
In the case of Isla Solar, the process can be done “turnkey”, that is, the company takes care of everything: from the initial study to assembly, technical assistance or the subsequent control, monitoring and maintenance of the installation. Likewise, the company offers multiple financing facilities, which makes it a perfect and accessible option for all customers.
Where can solar panels be installed
Installing solar panels is simple and very convenient, but what is the most appropriate place to enjoy the benefits of solar self-consumption? The ideal place to install solar panels is in the roof and facing southin this way the sunlight is better used. Apart from the roof, photovoltaic panels can also be placed on walls, gardens, floors or masts; The ideal is for it to be a clear place where the sun reaches well and which is high.
In addition, you should know that photovoltaic panels can be placed in a wide variety of spaces and places. These are the most common:
- Single-family homes, on roofs or flat.
- Neighboring communities, the installation is carried out on the roof of the building and everyone benefits from shared self-consumption.
- Companies and industrial warehouses.
- Public spaces: schools, hospitals, government buildings…
Although all these spaces can have panels, the solar panel installation company will be in charge of verifying the location, orientation and dimension of the installation, depending on the availability and energy needs that will be verified in the preliminary study.
How much does the installation of solar panels cost, is it profitable?
Is it profitable to install solar panels? If you have ever thought about betting on solar self-consumption, this question has probably arisen and we have the answer: yes. The photovoltaic installation not only It is a profitable investmentbut also sustainable and accessible. However, it must be taken into account that the cost of installing solar panels may vary depending on both the size of the project and all those components necessary for the installation. In this sense, the 2024 data tells us that the average cost of a 3kW installation is around €5,000 and €7,000while for a larger installation, of 6kW, the price is between €9,000 and €12,000. Although these prices may vary depending on the installation of photovoltaic panels required, there are certain economic aspects to take into account.
Currently, any client has within their reach the possibility of reducing the cost of installing solar panels thanks to the following economic facilities:
- Personal income tax deduction: The deduction for installing AEAT solar panels will vary in percentage depending on the community.
- Local and regional subsidies: some grants cover between 20% and 50% of the initial cost.
- Reduced VAT: If it is a residential installation you can benefit from this aspect.
In addition to these benefits on the price of installing solar panels, it is important that we talk about the profitability of the self-consumption system. In this sense, the installation of basic photovoltaic panels can be amortized over a period of 6 to 10 years, always depending on both energy consumption and the aid received. Furthermore, taking into account that solar panels are designed to have a useful life of about 25 years, the long-term savings can be very significant, in addition to having the option of generating extra income by managing the surplus energy generated.
At Isla Solar they work with sustainability, quality and profitability, therefore, if you are thinking about taking the step towards solar self-consumption, this is the best time.
