Solar panels
Solar panels convert solar energy into electricity, which is then used to power all the systems and devices in your home. When the solar panels do not generate enough electricity to meet your home’s demand, such as at night, additional electricity is drawn from the main power grid. If the solar panels generate more electricity than your home needs, the surplus electricity is fed back into the main power grid.

Components in a solar panel system:
Solar panels
Solar panels convert sunlight into electricity through photovoltaic cells. When selecting our solar panels, we take into account various essential factors, including:
- Technology
- Efficiency
- Temperature coefficient
- Sustainability
- Reliability
- Warranty
We have our own testing setup at our shop in Calpe, where we test solar panels for extended periods and in different seasons under Spanish weather conditions. Additionally, we utilize production data from our over 2,000 installed systems on the Costa Blanca. In this way, we ensure that our customers benefit from optimal returns and reliable performance for many decades.
With our 30 years of experience on the Costa Blanca and data from our systems, we prefer Longi Hi-Mo Explorer X6 – 435W solar panels of the “full-black” type due to their high test results regarding temperatures. This is particularly relevant due to the high summer temperatures in Spain. Additionally, these panels boast an impressive efficiency of 22.5%, offering a 25-year production guarantee and a 25-year performance guarantee. “Full black” means that both the frame and the surface of the panel have a deep black color, not to be confused with panels that only have a black frame.
*Longi Hi-Mo Explorer X6 – full-black – 435W
We sometimes receive the question why we work with “full-black” 435W panels instead of 500W+ panels. There are several important reasons for this:
- Wattage is not the only factor determining production. In addition to wattage, factors such as panel type, utilized technology, efficiency, durability, and temperature coefficient play significant roles. For instance, a 400W solar panels with a high temperature coefficient can produce more electricity in summer than a 500W solar panel with a low temperature coefficient.
- Roofs are not always 100% flat, especially with older roofs. Most older roofs are slightly lower in de middle and slightly higher on the the sides and/or the top/bottom of the roof. Placing long and large panels on such roofs can result in visible irregularities.
- Smaller panels are available in full-black models, which provide an attractive and modern appearance because these panels have a deep black color. This applies to both the frames and the surface of the panel. 500W+ panels are not available in full-black models and result in a less aesthetically appealing system, with grey frames, a purple hue, and white lines on the panels.
- Warranty periods. The full black panels we work with, as well as nearly all other full black panels, typically offer a 25-year product warranty and a 25-year performance warranty, while the larger, non-full black panels often only have a product warranty of 10 to 12 years. After the installation of tens of thousands of panels, we have not encountered a single full-black panel that has decreased in performance, while this has occurred several times with the 500W+ panels, confirming the higher quality of the full-black panels.
Our advice is always to choose the best full-black panels for their high production, high aesthetic appeal, and longer warranty period, rather than panels with the highest possible wattage at the lowest possible price. After all, you are buying the system for the coming decades, you will be looking at the panels in the coming decades, and you should be able to rely on them in the coming decades.
Mounting systems
Pitched roofs with roof tiles: When installing solar panels on pitched roofs with roof tiles, we use a storm-proof and leak-proof mounting system with materials from Würth. We drill a hole with a diamond drill through the top roof tile and the bardo (the layer under the roof tiles) and insert a threaded rod, which is then sealed with a waterproof substance. A profile is attached to the threaded rod, on which the solar panels are mounted.
Please be aware that in the municipality of Benissa, it is no longer permitted to install solar panels on rooftops if your house is situated within a “zona rustica” (rural area / countryside / campo). In Benissa campo, solar panels may now only be installed on the ground.
Flat roofs and in gardens: For flat roofs and in gardens, we use prefab concrete foundations with high-quality concrete or aluminum structures.
On walls: Solar panels can also be installed on walls using aluminum structures.
Pergolas and carports: For pergolas and carports, we use aluminum structures.
Important: In order to obtain a building permit for solar panels on a carport, there must be a minimum distance of 5 meters between the panels and the property boundary. Additionally, we can only apply for the permit if the carport is registered in the land registry, which we can check for you.
The system we offer depends on several factors, with wind forces, weight and the aesthetic impact of the system being the most important considerations.
If you wish to install the panels on the ground, at a location far from the house, we offer the possibility to construct a storage area for the inverter(s) and other components. This storage area, crafted in a Spanish style with roof tiles or a modern style, including a door, ventilation, plastering, and painting, has an approximate cost of € 550 including VAT.
What we do not do: We do not install solar panels on sloped tile roofs where the panels are oriented in the opposite direction. As shown in the image below, this is not only aesthetically unappealing, but it can also lead to conflicts with the municipality and neighbors. Additionally, this installation method is too vulnerable to heavy storms, and there is a high likelihood that insurers will not cover any damages.
Inverters (Smart Energy Controller)
An (grid-connected) inverter is an electronic device that converts direct current (DC) generated by solar panels into alternating current (AC), which we use in our homes. Additionally, the inverter can feed the surplus electricity produced by the solar panels and not needed for your home back into the electricity grid.
String-inverters: We use string inverters, with or without optimizers. With a string inverter, one main inverter is installed, usually in a technical room or garage, but it can also be installed outdoors. The inverter has an elegant design, and its dimensions are approximately 35 by 35 cm, so you will barely notice the system in your home. We exclusively work with premium hybrid inverters that can be expanded either immediately or later with more solar panels, battery storage, smart charging stations, backup solutions, and smart grid solutions.
We prefer Huawei inverters due to factors such as:
- Huawei has been the undisputed market leader in Spain for years
- The best app on the market
- General quality
- Compact size
- Very silent operation
- Long warranties
- Excellent price-to-quality ratio
- Excellent backend software for support and analysis
- When Huawei releases new products, they are almost always compatible with existing inverters
- Possibility of expansion with more solar panels, battery storage, optimizers, charging stations, and backup solutions, all integrated within one app
Micro-inverters: Due to the higher purchase price and the fact that micro-inverters only offer benefits in exceptional cases, we do not install micro-inverters.
Optional components:
Optimizers (Smart Module Controller)
The Huawei Smart Module Controller (optimizer) works in conjunction with the inverter to optimize the performance of individual solar panels, ensuring maximum efficiency of the solar panel system. Thanks to the optimizer, the system can deliver more power, even if some panels temporarily underperform due to shadow effects, or when the solar panels have different orientations or inclinations.
An additional advantage of an optimizer is that it allows you to monitor the individual performance of each panel through the solar panel system’s app.
Optimizers are not always necessary and will only be advised by us when they are necessary for the proper functioning of the solar panel system, or when you want to be able to see the individual performance per panel.
Optimisers kosten: € 69 inclusief BTW en installatie.
Battery storage (Smart Storage)
Huawei Smart Storage offers the ability to store electricity generated during the day in batteries for use during periods of low or no sunlight, or for when your home requires more electricity than the solar panels are generating.
- Starting at 5 kWh
- Modular expandable in increments of 5 kWh
- With a storage capacity of 5 kWh, the battery can deliver 2.5 kW (3.5 kW for 10 seconds), and with a storage capacity of 10 kWh, the battery can deliver 5 kW (7 kW for 10 seconds)
Control module + 5 kWh battery module: €4,030 including VAT and installation.
Price per additional 5 kWh battery module: €2,635 including VAT and installation.

Back-up (Smart Guard)
With the Huawei Smart Guard, your home switches to power from the batteries within 20 milliseconds after a power outage from the main power grid, ensuring uninterrupted power supply.
The Huawei Smart Guard distinguishes itself from a standard backup box by providing power to the entire home instead of just a specific group. As a result, no major modifications to the distribution board are required.
Expected in the fourth quarter of 2024.
The Huawei Smart Guard is compatible with virtually all Huawei inverters installed by us and can always be added to existing systems later.

4G Dongle (Smart Dongle)
When you do not have internet or when the inverter is located on a location without a Wi-Fi signal, but you still want to be able to use the solar panel system app, we can install a 4G dongle. With a 4G dongle, the inverter can be connected to the internet through the 4G network.

Possible additional (material) costs
Solar panels installed on flat roofs, carports, pergolas, or vertical walls are approximately. €18 including VAT per panel, more expensive due to additional materials and transport costs.
Possible additional (administrative) costs
In almost all municipalities, an additional certificate is required, prepared by a certified engineer or architect, when the panels are placed on a flat surface, such as on the ground, on a flat roof, on a pergola, or carport (certificado de solidez). In a small number of municipalities, this certificate is always required, regardless of where the panels are installed. In a small number of municipalities, additional documentation is required (estudio de seguridad y salud en estudio de residuos). When these additional administrative tasks are required, we will include them in the quotation.
Always includes all necessary paperwork
Due to the extensive paperwork load that varies from municipality to municipality, we adhere strictly to all applicable laws and regulations in each municipality. Our quotations are therefore carefully compiled per municipality and without exception include all required administrative documents and building permits, which are mandatory at all times and in every municipality.
Systems with an inverter capacity greater than 10 kW
If you wish an inverter with a capacity of more than 10 kW, a project plan needs to be prepared. The costs for this vary between 750 and 1250 euros, depending on the municipality.
Compensation for surplus electricity
When you generate more electricity than you need, the surplus is fed back into the main power grid. Your electricity supplier compensates you for this surplus electricity. These reimbursements are deducted monthly from the remaining amount you still owe. Most suppliers also offset these fees with the fixed connection costs. Additionally, some suppliers offer extras such as “virtual batteries,” options where you can save for discounts on gas or gasoline, or options to share electricity with other homes.
The average tariff for surplus solar electricity is approximately 8 cents + VAT.
Electricity suppliers: Tailored advice
Finding the right electricity contract can be a challenge for many, especially due to language barriers, the large number of suppliers, complex electricity bills, and frequently changing rates. We closely monitor the major Spanish electricity suppliers and provide tailored advice after installation. This is often beneficial, as many suppliers have attractive offers for people with solar panels.
If you live permanently in Spain, we generally recommend a contract with the lowest rates for electricity and the highest rates for surplus solar energy. If you don’t stay in Spain year-round, we usually suggest a contract with a virtual battery. Additionally, we always advise choosing a supplier that offsets the compensation for surplus solar electricity against both the consumed electricity and the fixed connection costs.
Administrative tasks that are (obligatory) included in our solar panel installations:
Registration trough the Generalitat Valenciana
To ensure that your system is known to the Generalitat Valenciana (GVA), it is necessary and mandatory to register the installation through the Generalitat Valenciana.
Registration through the grid operator
It is essential to follow the legalization process established by the grid operator (I-DE). This process ensures the official authorization and recognition of feeding surplus electricity back into the grid, allowing you to receive compensation for your surplus electricity.
Building permit
For solar panel systems, a ‘licencia de obras’ (building permit) must be applied for, paid, and approved by the municipality.
Certificado de solidez
In almost all municipalities, an additional certificate is required, prepared by a certified engineer or architect, when the panels are placed on a flat surface, such as on the ground, on a flat roof, on a pergola, or carport. In a small number of municipalities, this certificate is always required, regardless of where the panels are installed.
Certificado de seguridad y salud
In some municipalities, a “certificado de seguridad y salud” is required to apply for a building permit.
Certificado de residuos
In some municipalities, a “certificado de residuos” is required to apply for a building permit.
Project plan
If you wish an inverter with a capacity of more than 10 kW, a project plan must be prepared by a certified engineer.
Discount on property tax (IBI)
In almost all municipalities, homeowners have the possibility of benefiting from a discount on property tax (IBI).
Each municipality may determine and change the duration, amount, and conditions themselves. In the municipalities of Calpe and Benissa, the discount is 50% per year for 3 years (up to a maximum of 400 euros discount per year), followed by 25% discount for 2 years (up to a maximum of 200 euros per year). Most people pay more than 800 euros per year, so for them, this arrangement means a total discount of 1600 euros on the IBI over 5 years.
You do not need to be a resident of Spain to be eligible for this discount. You only need an NIE number.
We provide all the necessary documentation to obtain the discount, including:
Required administrative documents:

FAQ – Frequently Asked Questions
Where do you install?
As of January 1, 2023, we have reduced our service area in order to continue meeting the high demand and maintain the top-notch service that our customers have come to expect from us over the past 30 years. We are active in the Marina Baja and Marina Alta, from Denia to Villajoyosa, in cities and towns such as Javea, Benitatchell, Teulada, Moraira, Benissa, Jalon, Lliber, Alcalali, Calpe, Altea, Alfaz, Albir, and Benidorm.
Do the panels have to be cleaned?
Cleaning the panels when they are dirty increases their production. We recommend cleaning your panels at least once a year. You can clean the panels yourself with a soft brush or cloth, or you can hire a company or one of our partners to do this for you. The cost for this service is on average 5 euros per panel.
Do solar panel systems need maintenance?
Besides cleaning the panels, solar panel systems do not require any maintenance.
Does the system working during a power outage?
During a power outage, the system will stop functioning. Once the power outage is resolved, the system will automatically resume operation.
It is possible to have the system operate during power outages using battery storage (Huawei Smart Storage) and the Huawei Smart Guard.
What if roof tiles break during the installation?
We replace any roof tiles that get damaged during the installation process.
What makes your prices so competitive?
Our prices are set at a highly competitive level, made possible by the large volume of systems we install. This allows us to maintain an efficient cost structure and pass the savings on to our customers.
In addition, we handle all the paperwork in-house, without the use of third parties. For building permits, we do not work with administrative offices, but instead maintain direct contact with the relevant municipalities.
Do you install systems I bought myself?
No, we only install systems that include all materials, services, administrative tasks, and building permits.
Do you do paperwork for third-party systems?
No, we only install systems that include all materials, services, administrative tasks, and building permits.
I have purchased solar panels from another company and do not have the correct paperwork, or the company that installed my solar panels no longer exists. What now?
Whether we can assist you depends on several factors, the most important being that there are no outstanding fines from the municipality due to unrequested building permits for the solar panel system. Visit our shop in Calpe for more information, and please bring all documentation you have regarding the system during your visit.
Hooray! We are celebrating our 30th anniversary!
