How many solar panels do you need at home to save?

Have you ever considered using solar energy to save electricity at home? If so, how many solar panels do you need to do so? The answer depends on several factors, including the size of your home, the amount of light you need and the amount the sun can provide. In this post we will help you find out how many solar panels you need at home to save energy and answer all your questions.
How many solar panels do you need at home?
The first thing you need to know is that you will need a solar inverter and a battery to store the energy you have collected or are going to collect. This is known as a solar power system.
- The size of the battery depends on the amount of solar energy you can collect during a day and the amount of energy you need to provide light to your home. And in order to put numbers to all this, you first need to determine the size of your home and how much light you need.
- You also need to take into account the climate and location of your home.
A house of 80 meters on one floor is not the same as an isolated country house, or a triplex in the heights. Neither is a house where the air conditioning system is through hot/cold split air conditioners, or a house where you have gas for heating and cooking, and only use electricity for appliances.
The easiest way to calculate the amount of solar panels your house needs to start saving as soon as possible is to use an online solar energy calculator.

These calculators are an effective tool that will help you determine the amount of solar energy that the sun can provide in the location where you decide to put it (orientation, climate) taking into account the size and characteristics of your home (location, size, average daily energy consumption, habits, peak power that is reached and even the rate we have contracted).
- Examples of solar calculators that may come in handy: the OCU solar calculator is quite reliable, but is reserved only for its members. Or use the one from IKEA in collaboration with a company called Contigo Energía.
Putting solar panels at home whether they are roof or balcony solar panels is an investment that to be profitable must be calculated well, because if you do not take into account all the factors mentioned above you may be buying too many panels for your consumption needs (and those of your family), or you’re falling short.
As you know right now, saving electricity at home with solar energy is an excellent way to save money in the medium term, but not everything goes. Therefore, determining the amount of solar panels you need is the first step to start using solar energy in an efficient way for both your economy and the planet.
With the rise of these systems, situations as disparate as finding complete systems of solar panels with a large investment for houses with low consumption where elderly people live, or there is a low energy consumption by having heating and hot water with other systems are also detected. Therefore, it is not all about putting a plate and start saving. Before buying a lot and hanging it on the balcony or asking a company to install the “full equip” you should stop and make numbers.

Ways to install photovoltaic systems at home
From a complete PV system to a small solar panel unit, there are a variety of PV installation options for your home that you should be aware of.
- One of the most common (and also expensive) ways to install solar power at home is through a complete photovoltaic system. This would consist of solar panels, an inverter, a battery and other additional components. As you can imagine, these systems require a significant investment, but in return they offer a large amount of free energy for your home.
- Another way to install solar power is through individual solar panel units. These units consist of a solar panel, an inverter and very rarely a battery storage. These units are less expensive than complete systems, but also offer a limited amount of power. A good option for all households that do not need a large amount of energy or that due to the characteristics of their house, or a question of budget, cannot put a complete system.

Can I install solar panels myself and do I need professional help?
Ideally, once you have decided on the type of installation you are going to use, you should contact a qualified professional to install your system. However, many people choose to install their photovoltaic system on their own. For example, the famous solar panels for balconies. If it is advisable to have the help of a professional to ensure that the entire installation remains safe.
If it has been a long time since you have had a check-up, if it is a second-hand house, or if you have doubts that things are all right, don’t gamble with it. Before calculating how many panels are needed, where you would put them and all the cost, check the installation.
Conclusions and frequent doubts:
In conclusion, nowadays we have more and more ways to install solar energy in any home. From a complete photovoltaic system to be completely independent, to an individual unit of solar panels that you can hang from the railing of your balcony and plug into any nearby light point to help a little with consumption.
