An inverter is a type of electrical device that converts a solar panel's direct current (DC) into alternating current (AC). Most household appliances run on AC power. Even devices that use DC power (laptops, cell phones, batteries, etc.) have a built-in converter to convert AC power to DC power. Harold offers Sungrow, Sofar Solar, Fronius and Solaredge inverters for their safety, reliability and arc flame detection capability.

The solar panels offered by Harold last for at least 25 years, after which 80% of the initial productivity is guaranteed.

In our experience, the payback period is usually 6-10 years. As electricity prices continue to rise, payback periods will shorten further. One of the most important aspects is self-consumption - the more solar energy you consume, the shorter the payback period.

Solar panels can use direct or indirect sunlight to produce energy, but they don't work as well on cloudy days as they do on bright sunny days. Although estimates vary, solar panels produce about 10-25% of their normal power on a cloudy day.

Inverters allow the user to analyze electricity generation and identify installation problems and errors online and through apps.

If your inverter is capable of receiving more energy, it is possible. Contact our team for more information.

2-year installation, 10-year product and 25-year productivity guarantee. Read more about the warranty conditions here.

Batteries are a great way to store solar energy for later use. Using electricity stored in the battery may be cheaper than buying it online.
