Question 1

How do I choose the right solar panel for my home in Spain?

Accepted Answer

The choice depends on several factors: the available roof space, your average electricity consumption, and the orientation of the roof. At Innovadoras, we work with high-efficiency monocrystalline solar panels, ideal for maximizing production even on limited surfaces. We recommend requesting a personalized assessment to determine the optimal power rating based on your location on the Costa Blanca, Valencia or Murcia.

Question 2

What is the difference between a string inverter and a microinverter?

Accepted Answer

A string inverter converts the energy from all the panels at a single central point, which is efficient when the panels have the same orientation and are not affected by shading. A microinverter, on the other hand, is installed on each individual panel, optimizing production panel by panel. At Innovadoras we offer both solutions — including Solis inverters — and we advise you based on the characteristics of your roof and your installation.

Question 3

What solar battery do I need and what capacity is recommended?

Accepted Answer

The battery capacity depends on your nighttime consumption and the level of autonomy you want. For an average home in Spain that consumes between 8 and 12 kWh per day, a 10 kWh lithium battery is usually enough to cover the hours without sun. In our catalog you will find LithTech batteries from 5 kWh up to modular systems of more than 20 kWh, adaptable to any installation.

Question 4

What are mounting structures used for and which one do I need?

Accepted Answer

Mounting structures securely fix solar panels to the roof or the ground. There are different types depending on the roof type: coplanar systems for pitched roofs with tiles or metal sheets, and tilted structures for flat roofs or ground mounting. At Innovadoras, we offer approved supports that guarantee wind resistance and the durability of your installation.

Question 5

What electrical protections does a photovoltaic installation need?

Accepted Answer

Every solar installation must include protections on both the direct current (DC) side and the alternating current (AC) side. This includes fuses, isolator switches, surge protectors and residual current devices. These protections safeguard the equipment and the safety of your home. In our store you will find all the necessary protection components, selected to comply with the current regulations in Spain.

Question 6

Do I need permits or licences to install solar panels at my home?

Accepted Answer

In Spain, residential self-consumption installations require a series of procedures that vary depending on the autonomous community and the installed power. In general, minor works permits, authorization from the electricity distributor, and the legalization of the installation by an authorized installer are required. At Innovadoras, we guide you throughout the entire process so you don’t have to worry about the paperwork.

Question 7

Are Solis inverters compatible with LithTech batteries?

Accepted Answer

Yes, LithTech high-voltage batteries are compatible with the hybrid Solis inverters in our range. This combination makes it possible to manage energy storage efficiently, prioritising self-consumption and reducing dependence on the power grid. If you have any questions about component compatibility, our technical team will advise you with no obligation.

Question 8

Can I expand my solar installation in the future?

Accepted Answer

Of course. A well-designed photovoltaic system is scalable. You can add more panels, incorporate a battery, or expand the existing storage capacity. The important thing is that the inverter has enough capacity, or that this expansion is planned from the initial design. At Innovadoras, we plan each project with your future growth in mind.

Question 9

What type of solar cabling is used and why is it important?

Accepted Answer

Solar cabling must be specifically designed for photovoltaic installations, with certification for direct current and resistance to weathering and UV rays. We use H1Z2Z2-K solar cable in 4 mm² and 6 mm², which complies with European standards and ensures the safety and efficiency of the installation over the long term. Inadequate cabling can lead to energy losses and electrical risks.

Question 10

What regulations apply to solar installations in the Valencian Community and Murcia?

Accepted Answer

Photovoltaic installations must comply with the Low Voltage Electrotechnical Regulations (REBT) and the self-consumption regulations governed by Royal Decree 244/2019. In addition, depending on the municipality, urban planning permits and tax incentives such as a reduction in IBI may be required. At Innovadoras, we are familiar with local legislation and help you take advantage of all available benefits.

Question 11

How much can I save with a solar installation in Eastern Spain?

Accepted Answer

Savings depend on the size of the installation, your consumption and the amount of sunshine in your area. On the Costa Blanca, in Valencia and Murcia, we enjoy more than 2,800 hours of sunshine a year, which allows a typical 3-5 kWp installation to cover between 50 % and 70 % of annual electricity consumption. Many of our customers reduce their electricity bill by between 600 € and 1.200 € per year.

Question 12

What maintenance does a photovoltaic installation require?

Accepted Answer

Maintenance is minimal. It is recommended to clean the panels once or twice a year to remove dust and dirt, especially in dry climates. In addition, it is advisable to carry out an annual technical inspection of the connections, the inverter, and the protections. At Innovadoras, we offer preventive maintenance services so that your installation operates at full performance for more than 25 years.

Question 13

What warranty do the products sold by Innovadoras include?

Accepted Answer

All our products come with the official manufacturer’s warranty. Solar panels usually have a product warranty of 12 to 25 years and a performance warranty of up to 30 years. Solis inverters offer a warranty of up to 10 years. LithTech batteries come with warranties of up to 10 years or a specified number of charge cycles. In addition, as an authorized distributor, we handle any issue directly with the manufacturer.

Question 14

How does the purchasing and shipping process work in your online store?

Accepted Answer

You can browse our catalogue, add products to your cart and submit your order for review. Our team will check availability, add the shipping costs and send you an invoice with a secure payment link. You can also choose to pay directly by card or iDEAL. We ship throughout Spain and offer personalized advice to make sure you get exactly what you need.

Question 15

Do you offer technical advice before placing an order?

Accepted Answer

Yes, and that is what sets us apart. At Innovadoras, we do not just sell components; we also support you in planning your project. You can contact us by phone, email, or through our contact form to receive free, no-obligation advice. We help you correctly size your system and choose the most suitable components.

Question 16

I want solar panels and a home battery — how do I start?

Accepted Answer

Start with a free consumption study. Solar panels cover your daytime use, and a home battery (e.g. LithTech from 5 to 16 kWh) stores the surplus for the evening. At Innovadoras we size the whole set — panels + Solis hybrid inverter + battery — so they work together. We handle the installation and the legalisation, delivering a ready-to-use system on the Costa Blanca, Valencia or Murcia.

Question 17

How many solar panels do I need for my consumption?

Accepted Answer

As a rule of thumb, each installed kWp (about 2 modern panels) produces around 1,500-1,700 kWh per year on the Costa Blanca. A household using 4,000-5,000 kWh a year typically needs 6 to 10 panels (3-5 kWp). The exact number depends on your consumption, roof orientation and whether you add a battery. Request a free personalised study and we will give you the precise figure.

Question 18

Is a home battery worth it in Spain?

Accepted Answer

It depends on your consumption profile. If you use a lot of electricity at night, a battery raises your self-consumption from 30-40% to 70-80%, cutting your bill further and providing backup during outages. With current prices and the long life of LithTech lithium batteries (up to 6,000 cycles), the investment typically pays back within the system's lifetime. We will calculate your specific case free of charge.

Question 19

Can I install solar panels myself or do I need an installer?

Accepted Answer

You can assemble the mounting structure and place the panels yourself, and our shop stocks all the components. However, in Spain the electrical connection and the legalisation of a self-consumption system must be carried out and signed off by an authorised installer (boletín/CIE). Without that certificate you cannot legalise the installation or qualify for surplus compensation. Many customers buy the material from us and hire only the electrical work and legalisation.

Question 20

My solar installation is not yet legalised — who can arrange that?

Accepted Answer

Innovadoras legalises photovoltaic installations, including those built by another company or by yourself. A technician inspects the system, verifies it meets the REBT regulations, issues the electrical certificate (CIE) and handles the self-consumption registration with the grid operator and the regional authority. This gives you a legal installation, entitled to surplus compensation and covered by insurance. Send us your installation details and we will prepare a legalisation quote.

Question 21

What is legalisation of a solar installation and why is it required?

Accepted Answer

Legalising means officially registering your installation with the authorities and the electricity company. In Spain it is mandatory for self-consumption: it certifies the installation is safe (meets the REBT), lets you export and offset surplus energy, and avoids penalties. The process includes the electrical certificate (CIE), the technical report, the installation certificate and the self-consumption registration. Innovadoras handles all the paperwork for you.

Question 22

I'm looking for a heat pump — which one suits my home?

Accepted Answer

Aerothermal (air-source heat pump) technology draws heat from the air for heating, hot water and cooling with a single, highly efficient system. The right capacity depends on the floor area, insulation and whether you want just hot water or also climate control and pool heating. For an average home on the Costa Blanca a 6-12 kW heat pump is usually enough. We run a heat-load calculation and recommend the ideal unit, installation included.

Question 23

I want to heat my swimming pool — what is the best option?

Accepted Answer

The most efficient way to heat a pool is with a dedicated pool heat pump: for every kW of electricity it consumes it generates 5-6 kW of heat. Combined with solar panels, the cost of heating the water approaches zero. It extends your swimming season by several months — even year-round on the Costa Blanca. We size the pump to your pool volume and whether it is covered, and include the installation.

Question 24

How much does an aerothermal heat pump cost?

Accepted Answer

An aerothermal installation for an average home usually costs between €8,000 and €15,000, depending on the capacity, whether it includes underfloor heating or radiators and whether it also covers hot water and the pool. It costs more than a gas boiler but consumes far less (a COP of 4 means 4 kWh of heat per kWh of electricity) and qualifies for subsidies. Powered by solar panels, savings are maximised. We prepare a quote tailored to your case.

Question 25

What does the solar panel installation process with Innovadoras look like?

Accepted Answer

The process has 5 steps: 1) a free study of your consumption and roof; 2) a proposal and fixed quote; 3) permit handling; 4) installation by our certified team (usually 1-2 days); 5) legalisation and commissioning, including the self-consumption registration. We also support you afterwards with maintenance and service. All with a single point of contact, no surprises and full warranty.
