Nowadays, looking for efficient and sustainable alternatives to reduce your electricity bill is no longer a luxury, it is a necessity. And if we talk about the best way to generate your own clean energy, the answer is clear: photovoltaic solar energy.
But, how exactly does a solar installation work and what should you take into account? We give you the keys in a simple and structured way.
Connection to the grid or isolated: what's the difference?
Not all homes have the same needs. For this reason, there are two main types of systems:
- Non-isolated systems (connected to the grid): These are the most common. Your home consumes the energy produced by the panels and, if at a given time you need more (for example, at night), you automatically take it from the conventional electricity grid. If you have excess energy, you can feed it into the grid in exchange for compensation or store it in batteries for later use.
- Isolated systems: Designed for country houses or rural areas where electrical wiring does not reach. The house depends exclusively on its panels and batteries to function.
And if there is a general blackout, what happens with the non-isolated systems that we can install?
Many people think that if the street light goes out, their panels will continue to work. In standard connected installations (non-isolated), the system stops for safety. But with our systems you don't have to suffer: backup systems exist. These are special configurations that allow you to continue having electricity at home even if the general electrical network has gone down.
The role of batteries and orientation:
To get the most out of your installation, there are two key factors:
- The orientation of the panels: The orientation directly influences the amount of energy you will produce. A good inclination and orientation (ideally towards the south or with east-west combinations depending on your habits) will make a difference in your savings.
- Batteries: The sun shines during the day, but what happens when it sets or if the day is very cloudy? If your main consumption is at night, batteries are your great allies. They store the energy that is left over during the hours of sunshine so that you can use it when you really need it, ensuring that you do not lose a single kilowatt.
Electric vehicle chargers:
The energy ecosystem at home can be completed with electric vehicle chargers.
If you have or are thinking about buying an electric or plug-in hybrid car, your roof can be your own "gas station". At vull.cat we also take care of the installation of the electric vehicle charger, synchronizing it with your panels so that you can charge your car directly with the energy of the Sun. A round saving.
However, depending on the kilometers you have to do daily and the number of panels you install along with your home consumption, you may not finish charging your car completely.
In any case, the savings are considerable if you opt for an electric vehicle charger.
What is the installation process like?
We know that doing work at home can be a bit of a hassle, but the reality is that it is a very clean and fast process:
- Where are the solar panels placed? The installation is usually done directly on the roof of the house, taking advantage of a space that you do not normally use and where they receive the maximum possible radiation. We also install panels on the ground if the client has enough space and if the roof cannot accommodate the panels.
- How long does it take to assemble this type of system? The assembly is quick. In a standard single-family home, it takes between 1 and 3 days to have everything ready and working.
Starting to generate your own energy is easier than it seems. At vull.cat we help you design the ideal system for your home. Do you want to install a solar-photovoltaic system? Let's talk.
