Currently, it’s not easy to find specialized companies for solar energy. Many are simply at capacity and can’t take on more work. But what can you do if you don’t want or can’t wait forever? This is where comparison portals come into play.

Overview
What should you do before starting a PV comparison?

There are now a variety of online PV portals. Here are five portals that have many positive reviews and are trustworthy.
1. Zolar
Here’s how it works: To start a free and non-binding project calculation, you first specify at Zolar what type of house it is and how many people live in it. The energy consumption is automatically calculated. However, you can also specify your own electricity consumption. Then further information is requested, as is common on other portals (roof type, size, address, etc.). Zolar also offers flexible installment payments under certain circumstances.
2. Solarwatt
Solarwatt impresses with so-called “glass-glass solar modules,” which are said to be extremely powerful and robust according to Google reviews. Offers can be quickly and easily obtained on the website. First, it is asked whether it is for private or commercial use, then you select the preferred components. You can choose between solar modules, storage, or energy managers. Then you must indicate whether you want to use the system for heat generation or need an additional charging station for the electric car. After that, the usual questions about roof size, structures like chimneys or dormers, and annual electricity consumption are asked.
3. Enpal
Enpal offers fast, smooth, and professional handling from consultation to installation of the solar system. Additionally, the online configurator is very comprehensive. The fast delivery times, which are usually four to six weeks, make Enpal one of the fastest suppliers of solar systems among solar providers.
