Do you want solar energy in your home? Learn how to install solar panels yourself

Installing solar panels in single-family homes has become one of the most effective solutions to reduce energy consumption and embrace a renewable and sustainable source. In this step-by-step guide, we explain everything you need to know to install solar panels in your home, from initial planning to system commissioning.

Step 1: Energy Consumption Assessment
Before installing solar panels, it is essential to know how much energy your home consumes. You can review your electricity bills to calculate monthly and annual consumption. This will allow you to properly size the photovoltaic system.

Step 2: Feasibility Study and Orientation
Analyze your home’s location, roof orientation, and tilt. Solar panels must receive the maximum amount of direct sunlight, so a south-facing orientation and a tilt between 30° and 40° are usually ideal in Spain.

Step 3: Component Selection
Choose the right solar panels according to efficiency, warranty, and price. You will also need an inverter, mounting structures, wiring, and possibly batteries if you want energy storage. At Tienda Solar, you can find a wide range of certified products.

Step 4: Legal Procedures and Permits
Check with your local council and electricity distributor about the necessary permits. In many cases, a minor construction license and registration of the installation with the Energy Industry are required. You can also benefit from state subsidies and grants.

Step 5: Physical Installation
The installation must be carried out by certified professionals. This includes mounting the panels on the roof, connecting them to the inverter, and wiring to the electrical panel. It is important to follow electrical safety regulations.

Step 6: Connection and Commissioning
Once installed, the system must be inspected and connected to the grid if you want surplus compensation. The system is activated and starts generating clean energy for your home.

Technical Tips

  • Verify compatibility between panels and inverters.
  • Ensure the roof can support the installation weight.
  • Consider installing a monitoring system to track energy production.
  • Perform regular maintenance to ensure optimal performance.
