Still have an empty roof in a country with 300+ days of sunshine?
How many panels do I need?
This of course depends on your consumption and is different for everyone. When you send us your energy bill, we can view your consumption of the last 12 months and make you an offer based on your consumption. Despite the fact that you are reimbursed for the injected electricity, a system based on your consumption is the best investment. A panel of 400W aimed to the south (100×200 cm) will generate approx. 700 kWh per year. Please note that the panels generate a lot more in the summer than in the winter and that you cannot absorb your night-time consumption with solar energy (unless a battery is used).
What if there is shade on one or more panels?
Shade can negatively affect production. When shade can fall on one or more panels, optimisers are to be used. Optimisers ensure that the panels in the shade cannot negatively influence the panels in the sun.
Can I expand the system later?
In most cases you can expand the system with one, two or three panels of, for example, 400W. If you plan to expand with more panels in the future, we can offer a stronger inverter. Especially if you plan to heat your swimming pool electrically in the future or to switch to a heat pump, we recommend a future-proof inverter.
Which solar panels do you use?
We usually use solar panels from Jinko Solar or Sunpower. We only work with panels from tier 1 brands and when choosing, we mainly look at the available space. Our panels are monocrystalline, HC (half-cut) PERC panels with an efficiency of 20% or higher.
Which inverters do you use?
We usually use inverters from Fronius, Huawei, SMA or Victron. We only use inverters that are certified in Spain and we look at the wishes of our customers when choosing. There are normal grid-connected inverters, hybrid inverters (with battery storage option) and inverters with UPS function (can provide your house with energy in the event of a failure of the main power grid).
What happens if the main power grid fails?
A grid-connected system cannot supply your home with energy when the main power grid is lost, unless a UPS system or inverter with UPS function is used, such as the Fronius GEN24.
What about batteries?
Energy that you do not use can be stored in one or more batteries. Instead of returning the electricity, you can use this electricity at times when the panels generate little or no energy.
Do you also supply and install off-grid systems?
Yes. If you do not want to be connected to the main power grid or if you have a house without an energy connection (campo), an off-grid / standalone solar panel system with a battery bank can offer a solution.
Does the system need maintenance?
No, the system does not require maintenance, but cleaning the panels will improve production. From 2021 we will offer a cleaning service.
Do you lease, finance or rent systems?
No, at this moment we don’t.
How are the panels installed on the roofs?
With a diamond drill we drill a hole through the roof tile and the “bardo” (red stones used in roofing suits in Spain). Here we insert a threaded end and then the hole is sealed all around with a special waterproof glue so that there is no chance of leakage. Rails are mounted on the threaded end on which the panels are placed. There is a small space between the roof and the panels, so that cool air can flow under the panels.
How are the panels installed on flat surfaces?
For flat surfaces we use two types of prefab concrete foundations (fixed and adjustable in inclination) or aluminum constructions. The main focus is on the possible wind pressure and the aesthetic impact of the system. In most cases you will receive a wind pressure report from us regarding the mounting system.
Where do you install?
We install on the Marina Alta from Denia to Benidorm. If you live just outside of this area, please contact us.
What languages do the installers speak?
Our solar panel installation teams speak Dutch, German, English and Spanish.
Who installs the systems?
Our own team of FEMPA certified installers and electricians with a lot of experience on all roof types and surfaces.
What is the delivery time for installation?
On average 7 to 14 days.
How long does the installation take?
Installation usually takes a day (up to 12 panels). After installation, we come by for the paperwork and to explain the system and the accompanying app.
Do the systems have an app?
Yes. All our systems have an app. With this app you can view the production of the panels, the (live) consumption of your home, how much energy you feed back and how much energy you still get from the main power grid. The app can be used on Android and IOS devices and is also available in any internet browser (laptops / PCs).
How are the cables concealed?
The cables that go from the panels to the inverter are neatly concealed in cable ducts. The cables on the roof, which are not visible, are also placed in flexpipe. At the inverter, the cables are neatly hidden so that the whole will look ecstatically pleasing. A neat finish of the system is very important to us.
Are solar panels now legal in Spain?
Yes. Where you previously had to pay a tax on the returned energy (untill April 2019 – Impuesto del sol) you will now receive a compensation for the returned energy (real decree 244/2019).
What is the switch service?
The switch service is free for our customers. We look at which energy supplier can provide the best rates and lowest fixed costs in your situation and we transfer you. We do all the paperwork and communication and cancel your old energy contract.
What are the reimbursements?
You will receive a compensation of approx. 5 cents per kWh per kWh that is returned. The returned energy is stated on your monthly energy bill. The value of this energy is deducted from the energy you still have to pay. You continue to pay the fixed part of the bill (electricity connection and taxes) and the number of kWhs may not be negative.
What about the paperwork?
To receive reimbursements for returned energy, the solar panel system must be registered and the grid injection must be legalised at the Ministry of Industry. When this is done, we receive a certificate, with which we can go to the energy supplier to apply for the reimbursements. These administrative activities come included with our systems. We do not register and legalise third party systems.
