Solar Panels

Solar panels appear on more and more houses in Spain following recent legislative changes in the field of solar energy. When investing in a solar panel system, you can now have your money back within a few years. After that you have free electricity from your own roof. But what should you pay attention to when purchasing solar panels?

Why Solar Panels?

Lower Energy Bill

Even a small system will significantly lower your energy bill.

Renewable energy

Solar panels have no emissions and only use clean and free sunlight.

Great investment

Since 2019, solar panels have become an excellent investment in Spain.

Easy to install

Solar panels can easily be installed on any type of roof, terrace or garden.

Long warranties

10-year warranty on all inverters and solar panels and a 25-year guaranteed power generation.

No Maintenance
Solar panel systems have no moving parts making them virtually maintenance-free.
Usefull apps

All systems come with handy apps that show you a lot of information about you generation and usage.

Property value

Solar panels increase the home value and provide a higher energy rating.

Low panel prices

The prices of solar panels have never been this low, despite the huge demand.

How do grid-connected systems work?

Solar panels generate DC electricity. An inverter converts this electricity into AC electricity, the type of electricity that we use in our homes.

As soon as the sun rises and the solar panels start generating energy, your house will start using this energy. If the solar panels do not generate sufficient energy, extra energy will be taken from the electricity grid.

When the solar panels generate too much electricity, the excess energy will be injected into the electricity grid. Since 2019 you will receive a reimbursement for this from your energy company.

The energy taken and injected is measured by a smart meter. This data can be viewed on any smartphone or tablet.

Optionally, energy can be stored in one or more batteries. This energy can be used later when there is little or no sunlight. Batteries are currently relatively expensive, which means that batteries cannot be seen as a good investment, since the payback period is very long. However, the price of the batteries is falling rapidly. Solar Power Systems PV will inform all its customers when we think that batteries have become an interesting investment.

What Types of  Panels are there?

Solar panels come in different types. The most common are polycrystalline (“poly”) and monocrystalline (“mono”) solar panels. Polycrystalline panels are usually blue, slightly cheaper and slightly less efficient than the (usually) black monocrystalline panels. The quality differences between the 2 types are generally small.

At Solar Power Systems PV we mainly work with solar panels from Jinko Solar and LG. Jinko Solar panels are the best-selling solar panels in the world. Depending on the situation, we opt for panels of 200 by 100 cm (400 W – 72 cells) or 165 by 100 cm (330 W – 60 cells) of the type monocrystalline (“mono”) PERC with an efficiency of 19,88% and 19 ,68%.

How many panels do I need?

The average power consumption of a Spanish home without swimming pool is around 3000 kWh per year, which is around 8 kWh per 24 hours. This is an average of small apartments and large villas so this can vary considerably with your situation. We therefore recommend that you consult your energy bill for your average power consumption.

Also try to look at your future situation. Will you use a heat pump or one or more air conditioners in the future?

We always recommend choosing a system that does not generate more electricity than you use. If you want to be able to expand the system in the future, it is possible to purchase an inverter with a higher maximum capacity.

Average yield in Spain:

4 panels of 400W = approx. 8 kWh per day in winter and approx. 11 kWh in summer.

6 panels of 400W = approx. 12 kWh per day in winter and approx. 17 kWh in summer.

8 panels of 400W = approx. 16 kWh per day in winter and approx. 22 kWh in summer.

10 panels of 400W = approx. 20 kWh per day in winter and approx. 28 kWh in summer.

Is my roof suitable?

Almost all roofs are suitable for solar panels. The following guidelines help to determine whether your roof is suitable for solar panels:

Tilt angle: the tilt angle of the panels influences the yield. An angle of approximately 35 degrees is optimal. But the loss of efficiency with steeper or less steep placement is small (usually less than 10%). 60 degrees, or 20 degrees on a flat roof, is therefore certainly still profitable.

Direction: solar panels can best be oriented to the south. But (south) east and (south) west are certainly still profitable with an average of 5-15% lower yields.

Shadow: for roofs that are partially shaded, for example by a chimney, we recommend optimizers. The partially shaded panels therefore have no negative effect on the other panels that are in the sun.

Space: panels can be closer to each other on a sloping roof than on a flat roof. On a flat roof, it applies that more panels fit if you choose a smaller slope of the panels. Or if you have the panels installed “east-west”. One row then provides less shade on the next row. Less slanting also means less heavy ballast on the flat roof.

For sloping/inclined roofs we work with mounting rails which are attached to the layer under the roof tiles. The panels are mounted on these rails.

For flat roofs, terraces or garden we work with small concrete foundations.

High Quality Materials

At Solar Power Systems PV we constantly research the markets, looking for the best materials and always taking into account reputation, new and additional options and price / quality ratio. We mainly work with brands such as Fronius, Victron, Huawei, SMA and Jinko Solar, the world’s best selling solar panels.

Useful Apps

All our packages come with handy energy monitoring apps for your smartphone and/or tablet.

  • Check what your solar panels are generating
  • Check your energy consumption
  • Check what you deliver back to the power grid
  • Useful overviews, specifications, battery information and more

Would you like to have a demo of the app? Contact us!

Battery storage

With hybrid inverters it is possible to store energy in one or more lithium ion batteries from LG (CHEM Resu). You can use this energy later when there is little or no sunlight.

The unit has a beautiful design and is available in a 6.6 kW and a 9.2 kWh version. Via the app that you use to view information about your solar panels, you can also view data about the battery. Contact us for more information or click here.

Registration and legalization

In Spain, solar pv systems have to be registered and sending electricity back into the main power grid has to be legalized. There is a lot of uncertainty about this in Spain and this is why Solar Power Systems has invested a lot of time into this. Registering and legalising solar systems takes a lot of paperwork and a lot of time, but it comes standard with all of our solar systems.

Contact us if you have any questions about the registration and legalization.

We do not install, register or legalize systems from third parties.
