How many solar panels do I need? We end all your doubts

Currently installing energy efficiency improvements in the home is something that is fashionable. In fact, it is a highly recommended action for users looking to save energy and achieve greater comfort in their home. In addition, there are a large number of incentives for renewable energy installations in self-consumption such as photovoltaic panels. And this leads us directly to talk about solar energy.

A few weeks ago we told you everything you need to know about the maintenance and cleaning of solar panels. But today we are going to go further and answer the million dollar question: How many solar panels do you need for your home? It is the question that users ask us the most, so to solve the doubts we are going to tell you everything that you should take into account.

How do I know how many plates I need?

To correctly answer the key question of this publication, many factors must be taken into account. But possibly the most important of all has to do with the annual electricity consumption that we make at home. As a general rule, between 4 and 18 modules of photovoltaic panels are usually installed, both for homes and businesses. A fairly high fork.

However, it is possible to adjust them to the energy needs of each case to have a clearer answer. Below we offer a table of consumption and number of plates recommended for each case:

• Below 2000 kWh of annual consumption: between 2 and 4 plates, since the consumption profile is low.

• Between 2,000 and 4,000 kWh: a medium-low consumption profile that requires between 4 and 6 panels.

• Between 4,000 and 6,000 kWh: medium-high consumption that requires up to 10 solar panels.

• Between 8,000 and 10,000 kWh: high consumption that requires 15 to 20 photovoltaic panels.

How many solar panels are usually installed in a house?

The previous table is quite good to make an estimate based on your needs. However, other factors must be taken into account such as the type of solar panel from which it is brought. In addition to its performance, the orientation of the roof and the place where the home or business is located.

As a general rule,For a house inhabited by a family of 4 or 5 members, an installation of between 5 and 7 panels is usually sufficient. With these plates it is possible to generate around 5 kW. However it is not always so. For this reason, it is essential to contact experienced professionals who can carry out an inspection and determine exactly how many you would need to cover your needs.

Important aspects to keep in mind

In addition to everything we have discussed so far, other aspects must be taken into account. One of the most important has to do with the orientation of the plates, which should be located to the south if possible. Besides, the geographic location You can also make the number of solar panels needed to install vary. For example, in a city in the south of Spain fewer plates will be needed to generate the same energy as in one in the north.
