More and more people are committed to the environment and the use of renewable energy is becoming increasingly relevant in homes. Installing solar panels in your home is one of the decisions that is being made the most today to save on your electricity bill and to do your part in the fight against climate change.

But before installing the panels you have to think about several aspects.

1. How much does it cost?

The price of the panels must be calculated in cost per watt. Normally, the price is between €600 and €800 per m2.

That number changes as you make installation decisions. For example, if you want to add solar batteries or some other related element. In addition, you must choose between the different types of panels, each with its individual characteristics. As a general rule, those that work best in Spain, due to the climate, are polycrystalline panels.

You will also have to decide if you want to always use the photovoltaic panels to connect the electrical appliances or if you want to heat your house. In the second option you must generate more power by installing more plates.

Speaking of numbers, the most important thing before installing solar panels in your home is to know what your minimum energy consumption is.

Let's say you spend about €200 a month on solar energy. In the end, you would be saving around €45,000 over the lifetime of the installation. It is true that the installation involves an initial cost of €11,000 on average, but in the long term the great profitability of this project can be seen.

In addition, the price of this type of renewable energy has only fallen in recent years, while the price of electricity does not stop rising.

2. Does your house meet the requirements to install the panels?

Before embarking on this adventure, you must check that your house meets all the necessary requirements to be able to install solar panels without problem.

1. It must be facing south.
2. It must be inclined 15º-45º.
3. The terrain must be regular and square.
4. The shadow-free seating area.

Meeting these requirements would be ideal for placing the installation, but some of them can be solved by adding complementary structures.

Even if your house does not meet the requirements, the investment of placing this type of energy is still profitable in the long term. In addition, it provides added value to your home.

3. Recommendations.

If you want to choose the cheapest solar panels for your home, we offer you some recommendations that you should follow:

1. Compare budgets. Do not stay with the first company that gives you a budget, look for others online and ask for information.
2. Ask other people who already have solar panels. In this way, you will be able to know what type of installation they have and what company did it.
3. Look for possible financing. In addition, you should pay special attention to the guarantee offered by the company, both before and after installation.
4. CE certificate. The panels must comply with safety regulations.

 

These are some of the recommendations that you should take into account before installing solar panels in your home. We are facing one of the great investments of the moment, since more and more people make the decision to join renewable energies.
