Solar Panel FAQ

Yes. KiDi Solar installs battery storage and EV charging systems alongside new or existing solar installations. The battery and charger configuration is selected according to your electricity consumption, solar production and vehicle charging requirements. Tesla, Growatt, Huawei, Wallbox chargers.

Yes. KiDi Solar provides a complete turnkey service, including the required permits, technical documentation, certificates, legalisation and grid connection paperwork for your solar installation.

The installation time depends on the size and complexity of the system. After the site survey and system design, KiDi Solar provides a clear project schedule covering installation, commissioning and legalisation.

Solar installation prices depend on system size, electricity consumption, roof type, equipment and whether battery storage is included. Small residential systems typically start from around €5,000–€7,000, with the final price determined after assessing the property and energy requirements.

We provide free on-site solar surveys across the Costa del Sol and Málaga Province. Availability depends on your location and our installation schedule. Contact KiDi Solar and we will arrange the earliest convenient appointment.

Yes, if you choose a hybrid or battery-ready inverter. Compatibility is specific: the battery must be on the manufacturer’s approved list, match the inverter’s voltage range, communicate with it through its battery management system and run compatible firmware, sometimes with an extra accessory. That is why we plan battery compatibility from day one, even if you install the battery a few years later.

Yes. Huawei uses the FusionSolar app, Growatt uses ShinePhone, Deye systems are usually monitored with Solarman, and Victron Energy uses the VRM portal. You can see solar production, home consumption, battery level and grid export in real time. With your permission we can also monitor the system remotely and spot problems early.

Usually, yes, without replacing your panels. If your current inverter has failed, is out of warranty or you want to add a battery, we can replace it with a hybrid model sized to your existing array. First we check your panel strings, voltages and grid connection, and we handle the paperwork if the change affects your registered installation.

Usually, yes, if it is planned from the start. The inverter size, your contracted power and your supply (an 11 kW charger needs three-phase) all need to allow for it, and dynamic load balancing stops the charger from overloading your home. Some manufacturers, including Growatt, also make EV chargers that integrate with their monitoring app. Tell us if an electric car is in your plans and we will size the system accordingly.

A quality inverter typically lasts 10 to 15 years. Manufacturer warranties depend on the product family, model and region, and some require product registration. As a guide, Huawei and Growatt residential hybrid inverters commonly come with around 10 years, Victron Energy products with 5 years, and Deye between 5 and 10 years depending on model and distributor. We confirm the exact terms in your quote. Separately, KiDi Solar gives a 5-year warranty on our installation work.

Often, yes. Bifacial dual-glass panels also capture light reflected onto their rear side, so on flat roofs with a light surface, pergolas and carports they can produce several percent more energy. On a standard tiled pitched roof the panel sits close to the tiles and the rear gain is small, so a monofacial panel is usually the better value there.

Yes, if you choose the right equipment. Close to the coast we use panels certified to IEC 61701 (the salt mist corrosion test), prefer dual-glass panels, and use corrosion-resistant aluminium and stainless steel mounting. We check the certificates on each datasheet before recommending a panel for a seafront property.

You can usually add panels later if your inverter has spare capacity. It is best to match the new panels to the existing ones on the same string (similar power, voltage and current); otherwise we put them on a separate MPPT input or add a second inverter. We plan for future expansion from the start, so tell us if you expect an EV, a heat pump or a pool in the coming years.

A light clean once or twice a year is usually enough, plus an extra one after a calima, when Saharan dust settles on everything. Rain removes most normal dust, but a heavy dust layer can cut production noticeably. Never use high-pressure water or abrasive products. We offer a maintenance and cleaning service.

Yes, slightly. Every panel loses a small amount of output for each degree its cells heat up above 25 °C, which is the temperature coefficient on the datasheet (around -0.26 to -0.30% per °C for modern N-type panels). On a hot July afternoon that can mean a 5–10% dip. We reduce this by choosing panels with a low temperature coefficient and leaving ventilation space under the panels. The long sunny season more than compensates, which is why solar pays back so well here.

The national MOVES III programme closed to new applications at the end of 2025, and there is currently no direct state grant for home charging points. In 2026 you can still deduct 15% of the installation cost of a charging point in your income tax return (IRPF), on a maximum base of €4,000. Check the current conditions with your tax adviser.

It is possible, but rarely the best use of a home battery: a car can empty a typical 5–15 kWh battery in an hour or two, leaving nothing for the house in the evening. We usually set up the system so the car charges from daytime solar surplus and the battery is kept for the home at night.

Yes. With a smart charger and an energy meter, the car charges from the solar power your home is not using. It works best when the car is parked at home during the day. You can choose solar-only charging, or solar topped up from the grid to keep a minimum charging speed.

Yes. Under article 17.5 of Spain’s Horizontal Property Law, a charger for private use in your own parking space needs only prior written notice to the community, not a vote. You pay for the charger, the installation and the electricity, and the work must comply with the electrical regulations (ITC-BT-52).

Most homes on the Costa del Sol have a single-phase supply, which allows up to 7.4 kW, enough to add about 40 km of range per hour and fully charge most cars overnight. An 11 kW charger needs a three-phase supply and a car that accepts 11 kW AC. We check both before recommending a charger.

Solar installations in Andalusia may qualify for subsidies, tax incentives or local tax reductions, depending on the property, municipality and programmes available at the time of installation. KiDi Solar helps clients identify applicable incentives and prepares the required technical certificates and documentation where the project meets the relevant requirements.
