Electricity production by solar panels works by capturing the sun’s energy to turn it into electricity for your home or business.
Solar panels can easily be integrated into any home or business. They are silent, produce no emissions, have no moving parts and require no fuel other than free sunlight. They are modular, relatively easy to transport and install and have very low maintenance requirements.
Solar Power Systems was the pioneer of these systems on the Costa Blanca and has been supplying and installing them since 1994.
There are many reasons why homeowners go solar, but improving the environment and cutting energy costs are the most common. Many people are aware that solar panels are a great home efficiency upgrade and are eager to reduce their carbon footprint while also improving property value and lowering their electricity bills.
Simply put, solar panels work by allowing photons (particles of light), to knock electrons free from atoms, generating DC electricity. A solar inverter is used to convert this DC electricity into AC electricity, the type of electricity we use in our homes.
Grid-connected systems are connected to the main power grid. The electricity generated by the solar panels is first used for your home and the electricity that is not used by hour home is exported onto the main power grid.
Grid-connected systems will only supply electricity during the day when there is sunlight. When there is no sunlight, your home will use electricity taken from the main power grid. Most grid-connected systems work without the use of battery storage, however this is very much possible with our expandable and modular inverters. With batteries, you will also use your self-generated electricity at times without sunlight.
Off-grid systems are not connected to the main power grid and will have to generate enough electricity to power your home at all times. They are a perfect and often the only solution for homes without a power grid/Iberdrola connection. During the day, the solar panels will generate electricity and supply your home with power. Besides supplying your home with power, they will also charge a battery bank. When the sun goes down, and the solar panels stop generating electricity, your home will use the electricity stored inside the batteries.
Off-grid systems must be designed properly so that it will generate enough electricity to meet your home’s requirements. This includes supplying the house with electricity during multiple days with little sunlight. All of our off-grid systems are designed with 3 days of autonomy. This means that your home will have enough electricity stored inside it’s batteries, to power the house for at least 3 days without sunlight.
Hybrid systems are a mix between grid-connected and off-grid systems. Hybrid systems are connected to the main power grid, but also make use of battery storage.
A hybrid system will supply the house with electricity during the day, and will also charge a battery bank. When the sun goes down, the house will start using the electricity stored inside the batteries. When the electricity in the batteries is depleted, electricity will be taken from the main power grid. With hybrid systems it is also possible to charge the batteries at night using electricity taken from the main power grid. Because this happens at night, this electricity will only cost you the night tariff, in stead of the more expensive day tariff.
In order to choose the right size of your solar system, we must first find out what your average electricity use is. To do this, you can check your energy bill. When the energy bill is not clear or does not show your average use properly, we can install a temporary electricity meter. This device will measure the electricity used in order to give a clear indication of your average use.
The average use of a Spanish home without swimming pool is about 8 kWh per day (24 hours). A swimming pool filter-pump is not calculated in this example. We always advice to let this filter-pump run at night during the night tariff, or we advise a separate solar pool filter pump.
To give you an idea of how much electricity is used by an average home per 24 hours, we give you a small example of what 4 kWh entails. 4 kWh is about half of what the average Spanish home uses per 24 hours.
10 Light bulbs 5-12W – 3 hours per day – 215Wh
42-inch TV – 4 hours per day – 480Wh
Cold washing machine – 0.5 hours per day – 250Wh
Refrigerator A++ – 24 hours – 720Wh
Microwave oven – 0.2 hours per day – 140Wh
Oven – 0.5 hours per day – 900Wh
Washer dryer – 0.5 hours per day – 900Wh
Laptop – 2 hours per day – 150Wh
When you know what type of system you would like to have and what your average electricity use is, we would gladly make you a obligation free quotation. Enquire a quotation via our website, phone, whatsapp or email, and you receive a detailed quotation within 1-2 business days.
