How do grid-connected solar panels work?
Solar panels harness the energy from sunlight to generate electricity that is used to power all of the systems and devices inside your home. If the solar panels do not generate enough electricity to meet the demand of your home, such as during the night, additional electricity will be drawn from the main power grid. If the solar panels generate more electricity than your home requires, the excess energy will be returned to the main power grid.

What are the main components of a solar panel system?
Solar panels
Our systems come with high-quality photovoltaic panels to capture sunlight and generate electricity. We have over 30 years of experience on the Costa Blanca and carefully select our panels for optimal performance. We only use top-quality panels with an efficiency of 22% or higher, produced by leading tier 1 manufacturers such as Sunpower, Hyundai and Jinko solar.
Inverter(s)
Solar panels generate DC electricity which is then converted into AC electricity, the type of electricity used in homes, by an inverter. The inverter we use depends on the specific situation. We may use a string inverter, which consists of one single unit placed inside the house, or micro-inverters, which are installed on the back of each individual panel. In most cases, we use string inverters, only opting for micro-inverters in special cases. We only use premium inverters from global market leaders such as SolarEdge, Huawei, and Enphase.
Optimisers (when necessary)
If a string inverter is used, panels that may be prone to shading must be equipped with an optimizer. This ensures that a panel in the shade does not negatively impact the performance of panels in full sunlight. Optimizers also help to mitigate mismatches when panels are installed with multiple inclinations or orientations.
Battery-storage (optional)
Surplus electricity can be stored inside one or more lithium-ion batteries to be used during times of low or no sunlight. Battery-storage can be interesting when you charge the battery every day and discharge the battery every night. If you do not live in Spain all year we do not advise battery-storage, due to the relatively high cost.
We often advise to live with the solar panel system one winter and one summer, to then look at your consumption together, sow we can better advise you wether battery-storage is a good investment for you. A solar panel system in Spain is always a good investment, but wether battery-storage is a good investment for you, depends on your specific situation.
Battery storage is available from approx. 4.900 euros including IVA (base module, one 5kWh module and installation) and is expandable per 5 kWh (max 30 kWh).
Because we use hybrid inverters, you always have and keep the option to extend the system with battery storage, immediately or at a late point in time.
Mounting system
Inclined roofs with roof tiles: When installing solar panels on inclined roofs with roof tiles, we use a storm and leakage-proof mounting system with materials from Würth. We drill a hole through the upper roof tile and the bardo (the layer beneath the roof tiles) using a diamond drill and insert a threaded end, which is sealed with a waterproof adhesive. A profile is attached to the threaded end and the solar panels are mounted onto the profile.
Flat roofs: For flat roofs, we use either aluminium structures with wind skirts or prefab concrete foundations.
Pergolas and carports: On pergolas and carports, we typically use aluminium structures.
On the ground: When installing on the ground, we usually use prefab concrete foundations.
Vertical walls: Solar panels can also be installed on vertical walls using aluminium structures.
The system we choose depends on various factors, with wind forces and the aesthetic impact of the system being the most important considerations.

Paperwork, certificates, permits, reimbursements, IBI discount and subsidies
Solar panel systems in Spain require a significant amount of paperwork, more than in other parts of Europe. All of our systems come with the necessary paperwork, permits, and certificates included. We handle all of the communication and work for you, so you don’t have to do anything yourself
Registration via the Generalitat Valenciana (GVA)
Any grid-connected solar panel system must be registered with the Generalitat Valenciana. The paperwork and costs for this process are included in our prices.
Building permits (obra menor) via the municipality
Our systems come with the required building permits included. Building permits are mandatory, and the work and costs for obtaining them are included in our prices.
Legalisation via the grid-operator (I-DE)
The injection of surplus electricity must be legalised through the grid operator in order for your electricity supplier to reimburse you for the surplus. The paperwork, communication, and costs for this process are included in our prices.
Switch between the digital meter and main power grid
There are several regulations that solar panel installers must follow to comply with legislation. One of these is the requirement for a physical switch to be installed between the main power grid and the digital meter of the grid operator. If this switch is not installed, your electricity supplier will not reimburse your surplus electricity. The grid operator will check the placement of this switch in the weeks following installation. You don’t have to be at home when the grid operator come to check the switch, as it is located in the cabinet of the digital meter. The switch installation is included in our prices.
Reimbursements for surplus electricity
Your electricity supplier pays you for your surplus electricity. The amount you receive per kWh can range from 10 to 20 cents + IVA per kWh. These reimbursements will be taken of the amount you still have to pay for electricity used at night. This is done monthly. You continue to pay for the fixed part of the invoice which may include fees for taxes, grid maintenance, and other services.
An example: If you consume 100 kWh of electricity and sell 50 kWh back to the grid, your electricity supplier will reimburse you for the 50 kWh of surplus electricity. If you consume 50 kWh and sell 100 kWh, you will only receive a reimbursement for 50 kWh. The excess 50 kWh will not be compensated. A solution to not ‘’loose’’ this electricity is a physical or ‘’virtual’’ battery. For more information and prices about battery-storage and virtual batteries, contact us or visit our shop.

Frequently Asked Questions
Where do you install?
Effective January 1, 2023, we will be reducing our service area in order to make sure waiting list do not go over 3 months and uphold the high-quality service that our customers have come to expect over the last 30 years. We will continue to serve Calpe, Benissa, Moraira, Teulada, Altea, Jalon, Benitatchell, and Javea.
Do the panels need to be cleaned?
Proper cleaning of your panels can increase their production. We recommend cleaning your panels at least once per year. You can clean the panels yourself using a soft brush or cloth (do not use a pressure washer) or you can hire one of our partners to do it for you. The cost is 5 euros per panel for easy-to-reach panels and 8 euros per panel for those that are difficult to access. If your panels are easy to reach, we suggest rinsing them with water after sand/dust rains to maintain optimal performance.
Does the system work during a power outage?
During a power outage, the system will stop functioning. Once power is restored, the system will resume operation automatically. It is possible to have the system work during power outages using a backup box or UPS solution. Because power outages do not appear often and usually only last for a couple of seconds, we usually do not advise UPS solutions, due to the relatively high costs.
What happens when roof tiles break during installation?
We will replace any roof tiles that may be damaged during the installation process. If we anticipate that a significant number of roof tiles may need to be replaced, we will inform you before installation. If more than 50 roof tiles need to be replaced, we charge a very low and flat rate of 25 euros per square meter, including IVA, for the replacement tiles and installation.
Do you register / legalise / inquire permits for third parties?
No, as we take full responsibility for our installations, we only install installations with all materials, services, and administrative work included.
Can I get a discount on my IBI?
In most municipalities, you can receive a discount on your property tax (IBI). These discounts can be as much as 50%, with a maximum of 400 euros per year for a period of three years, and 25% with a maximum of 200 euros per year for a period of two years. The specific rules for these discounts can vary by municipality. To be eligible for the IBI discount, you need to provide the necessary documentation to your local SUMA office. This documentation will be provided to you by us after the installation is complete.
Beware that there is a possibility that the discount may be discontinued due to political changes and that it is often the case that the discount is not granted in the first year after applying.
Do you install materials I bought myself?
No, we only install installations with all materials, services, and administrative work included.
Do you sell materials seperately?
Yes, we sell inverters, optimisers, batteries and solar panels in our shop in Calpe.
Do you lease or finance systems?
No, we are not currently offering lease or finance options.
Pricing (all-in-one packages)
Approximate prices for our most popular residential all-in-one packages, including all materials, services, installation, and paperwork. These prices are based on an inclined roof with roof tiles (south oriented south / 25 degree inclination) and do not include optimisers (optional) or battery storage (optional). Systems installed on flat surfaces are slightly more expensive due to additional materials costs (25 euros + IVA per panel and 150 euros + IVA for use of a solar elevator or crane)
