Chapter 01
What is solar energy?
Solar energy is generated from sunlight, converted into electricity through photovoltaic panels. This electricity can be used immediately or stored in batteries for later use.
Chapter 02
Benefits of solar energy
Savings on your electricity bill
The reduction can reach 95% of the monthly amount.
Sustainability
Lower carbon emissions and less reliance on non-renewable sources.
Increased property value
Homes with solar systems are more attractive on the property market.
Low maintenance
Photovoltaic systems are long-lasting and require little maintenance.
Chapter 03
Types of solar energy systems
On-Grid
Connected to the grid, it lets you sell surplus energy.
Off-Grid
Independent of the grid, ideal for remote locations, requiring batteries for storage.
Hybrid
Combines both systems, offering more flexibility.
Chapter 04
How installation works
1
Feasibility analysis
Assessment of electricity consumption and available space. Higher-power panels generate more energy in less space — ideally choose 550W models or above, preferably monocrystalline.
2
Design and quote
Defining the power required and the costs involved.
3
Purchasing the equipment
Panels, inverters, batteries (if needed) and support structure. A central hybrid inverter can be an excellent choice, as it already includes a battery input.
4
Installation and connection
A specialised team handles the assembly and connection to the grid.
5
Certification
Approval from the energy distributor to formalise the system.
Chapter 05
Costs and return on investment
The initial investment can vary depending on the size of the system, but the return usually falls within the range below, depending on consumption and the local electricity tariff.
11 months – 7 years
average payback period on the investment
Chapter 06
Care and maintenance
Periodic cleaning
Cleaning the panels to prevent dirt build-up.
Monitoring
Tracking the system to ensure maximum efficiency.
Annual inspection
A professional inspection to verify proper operation.
Chapter 07
How to choose a trustworthy supplier
Reputation
Look for certified companies with good recommendations.
Quality
Check the quality of the equipment offered.
Warranties
Review the warranties and technical support.
