The cost of 1 solar panel depends on several factors, such as the type, quality, size, and location of the panel, as well as the installation and maintenance costs. Generally, monocrystalline panels are more expensive but more efficient than polycrystalline panels. The price of a solar panel also varies by the wattage, which is the amount of power it can produce. A typical 400-watt monocrystalline panel can cost between 320 and 480 euros, while a 400-watt polycrystalline panel can cost around 240 euros.
The cost of a solar panel system for your home or business will depend on how many panels you need, the size of your roof, the local incentives and rebates available, and the financing options you choose. According to a web search, the average cost of a residential solar system in Spain is about 6,000 euros for a 6kW system, or about 1 euro per watt, after applying the 26% federal tax credit. However, the cost can vary significantly by region and installer, so it is important to compare multiple quotes from local installers to find the best deal for your situation.
