Self-consumption is here to stay. In terms of energy, we’re talking about individual and personal electricity production, either for domestic or business use, thanks to systems such as photovoltaic panels, which, when placed on roofs or terraces, transform the sun’s energy into electricity.
Experts in the sector confirm that photovoltaic self-consumption offers you all the guarantees you could wish for. In fact, companies such as MyGreenHouse carry out feasibility studies that confirm that installing solar panels on homes, buildings and industrial warehouses is an excellent idea, as the savings are practically immediate right from day one and the return on investment occurs in a surprisingly reasonable time.
In addition to this, solar energy is our future. Unlike fossil fuels or conventional natural resources, the sun’s energy is 100% renewable, as it comes from an infinite energy source. Moreover, it is free and clean, as it doesn’t pollute with CO₂ and doesn’t produce waste. And, finally, it’s easily accessible, since we don’t have to produce, extract or transport materials from one place to another.
Even so, despite all these benefits, it’s still important to assess the advantages and disadvantages of solar energy if you are considering investing in self-consumption in your home or business.
Advantages and disadvantages of solar energy: the key issues
Some of the main advantages of solar energy are the following:
In some regions, self-consumption with photovoltaic energy can meet 100% of a household’s energy needs, including lighting, heating and air conditioning, water heating etc.
In cold areas, this may fall to 50%, but there are still considerable savings.
- An abundant energy source
One of Spain’s most defining features is the sun. Indeed, one of the advantages in our country is that we have the “raw material” to generate solar energy practically everywhere.
Even so, when planning a self-consumption installation and assessing the advantages and disadvantages of solar energy, we must take into account our location, as the hours of sunshine in Cadiz are not the same as in Santander, for example.
- Much more affordable systems
In recent years, the high demand for photovoltaic system components has led to lower costs. Self-consumption photovoltaic systems used to be extremely expensive, but now they are much more affordable.
Photovoltaic system maintenance is minimal and this is another significant benefit. We simply need to keep the panels clean and get a specialist to check that the insulating rubbers and components are in good condition (no cracks or breaks, etc.).
- Increases property value
Houses with self-consumption systems are considered more efficient and sustainable and this increases their market value, both for renting and selling.
As regards disadvantages of solar energy, we can highlight the following:
- Energy storage problems
One of the disadvantages of self-consumption solar energy is how to make use of the surplus energy produced during the hottest hours when your energy needs are not so great, or when you need more energy than you produce. Because of this, the best solution is to opt for batteries for solar panels.
- The complexity of installation in urban areas
Almost 80% of the Spanish population lives in densely populated urban areas, where it often isn’t easy to install self-consumption solar panels on buildings, both because of the lack of available space and the layout of the building. However, if you follow all the necessary procedures, it is possible to install them.
- Changing legislation
Even though progress has certainly been made in this area, the legislation on energy self-consumption is different in each country and even in each Autonomous Community. For this reason, we would always advise that you seek advice from professionals in the sector who can inform you about the different administrative procedures in your particular case. Here at MyGreenHouse, you can have peace of mind, as we will take care of all the paperwork.
- A high initial investment
In a discussion about the advantages and disadvantages of solar energy, the financial aspect always comes up. Even though long-term profitability is assured, it’s true that buying photovoltaic panels and batteries involves a considerable initial outlay. However, having said that, here at MyGreenHouse, we’ll make it easy for you and you can finance your system in up to 132 months without having to make any initial outlay.
Do you need any more information?
Installing solar panels is an important decision that will bring you many future benefits. We recommend that you seek expert advice in order to design the most suitable installation for your home according to its orientation, geographical location, and the area you have available on the roof or the terrace.
