Solar energy: advantages, types and how to install it at home

Solar energy is an excellent option for those looking to reduce their environmental impact and save on their energy bills. With an accurate calculation on the type and amount of panels you need, you can make the most of this renewable energy source in your home. Although the initial investment can be considerable, the long-term benefits in terms of economic savings and sustainability make it worthwhile.

In this blog you will learn about all the advantages and steps you will have to follow to install solar energy in your home or business.

Advantages of solar energy

The sun has become one of the most popular energy sources due to its numerous advantages:

Renewable energy:

Solar energy is inexhaustible and sustainable. It reduces our dependence on fossil fuels such as coal, natural gas, oil, etc.

Reduces carbon footprint

By not emitting greenhouse gases, solar energy helps combat climate change.

Economic savings:

Once installed, solar energy significantly reduces electricity bills and can even cost zero. The average payback period for installation is between 4 and 8 years.

Low maintenance:

Solar systems require minimal maintenance and have a long lifespan.

Grants and subsidies:

Many countries and states offer tax incentives that can reduce the total cost of installation by 10% to 30%.

Make money by selling your surplus.

You can transfer the photovoltaic surplus to your electric company so that it can be returned to you in the form of a discount.

Types of solar energy

Photovoltaic

Function: convert sunlight into electricity.
Applications: Ideal for generating electricity in homes and businesses.

Thermal solar

Function: They use solar energy to heat water or air.
Applications: Domestic hot water or space heating.

Hybrid

Function: Combination of photovoltaic and thermal panel for DHW and electricity. (See prototype here).
Aplications: Ideal for large installations such as hotels as it increases their efficiency.

How to install solar energy at home?

1. Preliminary study

Before installing solar, consider the following steps:

Assess feasibility: Check if your home receives enough sunlight throughout the year.

Energy consumption analysis: Calculate your energy consumption to size the appropriate system.
Budget and Financing: Consider initial cost and explore financing options and incentives.

2. Component selection

Los componentes básicos para una instalar energía solar incluyen:

Solar panels

The amount and type will depend on your energy needs.

Inverters

They will convert the direct current (DC) generated by the panels into alternating current (AC) usable in the home.

Batteries

To store excess energy and use it when there is no sun.

Framing

To secure panels to the roof or other surface. Framing may be inclined or coplanar.

3. Installation

Installation must be carried out by professionals to ensure efficiency and safety:

Permits and regulations: Obtain the necessary permits according to local regulations. The installation company is usually responsible for the paperwork.

Panel installation: Optimal placement on the roof or on the ground. Depending on where the home or business is located, the use of cranes will be necessary to facilitate installation.
System connection: Integration with the home’s electrical system.
Testing and commissioning: Verification of the correct and efficient operation of the system. If the installation exceeds 15 kW and discharges excess electricity, access and connection permits to the electrical grid must be requested.

4. Maintenance

Proper maintenance will ensure optimal performance of the installation and a much longer lifespan. It is recommended that this type of maintenance is always carried out by a professional.

Regular cleaning: Clean the panels to prevent dust and debris from accumulating. They are usually cleaned directly by rain. However, in areas with a lot of wind, high pollution, dust or dirt, it is advisable to clean them once a year to prevent their performance from decreasing.
Periodic Inspections: Check the condition of the system and electrical components.
Upgrades: Consider technological improvements that can increase system efficiency.

5. Increase savings even more

Heat pumps can work in conjunction with solar energy systems to maximize energy savings and increase overall home efficiency:

Zero production cost: Solar panels can power heat pumps to generate hot water for sanitary use, further reducing operating costs. A clear example of this type of heat pump is Efitherma’s “AQ-FV”. (More information here).
Simultaneous production of DHW and electricity: It is also possible to obtain domestic hot water and electricity by installing a single system and saving space, as for example offered by 2Water Hybrid. An ideal hybrid system for installations that require a high demand for DHW and electricity.
