Interested in solar? One of the top questions on your mind when you start to research will most likely be: How much will a solar panel system cost me?

Solar panel system installation is taking off in many countries, including Spain, where soaring electricity bills are a major concern. The good news is solar panel system installation costs have fallen significantly. 

What impacts the cost of your solar panel system?

Just as your home’s features are unique to your preferences, each solar panel system should be customized to suit your own needs, such as electricity use and property. Here are six main factors that impact the cost of your solar energy system:

  • System Size: The size of your solar panel system will depend on your electricity use. The bigger the system, the pricier it will be.
  • Battery Storage or Not: There are various reasons why people choose to include batteries in their solar panel systems. If you add batteries, note that these can add some cost to your solar panel system upfront.
  • Location: Installation cost varies by country or region.
  • Your roof’s solar potential: If your roof receives fewer hours of sunlight, your system will need more solar panels.
  • Equipment: The type and quality of your equipment, such as solar panels, inverters, and batteries, will impact the total cost of the system.
  • Labor: Solar companies charge different installation rates.

Should you lease or own?

The installation costs depend on whether you own your solar panels or sign a lease or Power Purchasing Agreement (PPA).

In both cases of solar lease and PPA, your upfront cost will be lower. As discussed in this article, with a solar lease, you agree to a fixed monthly payment determined by your installation company. With a PPA, you pay a set price per kilowatt hour (kWh). If you signed a lease or PPA, moving to a new location or selling your home can be tricky. Make sure you discuss these policies with your installer.

Owning your solar panels does have its upsides. While it initially comes with a higher installation cost, you are eligible for local incentives and may save more in the long term. In addition, homes with eco-friendly features, such as solar panel systems can sell for higher values according to this real estate research.

Do you qualify for government incentives?

If you own your solar panel system, you might be eligible for federal and local government financial incentives! Search what your government offers or ask your installer for available incentives in your area.
