More than solar panels

Kilowat designs, installs and maintains complete energy solutions, not just panels. Our teams size and build solar systems for homes, businesses and industrial sites, using Tier-1 equipment and established engineering standards.

We operate in Romania, Spain, Germany and, since 2026, Tanzania. Tanzania is a long-term market for us, where we are building a local presence backed by the methods and equipment we use across Europe.

Why we are in Tanzania

Tanzania receives some of the highest levels of solar radiation in the world, while electricity prices keep rising and many sites still depend on diesel. We see this as a market ready for solar, and we are building our operation here for the long term.

Our Tanzania team combines local staff with the equipment and engineering standards we use in our other markets, sourced from the same Tier-1 manufacturers.

Local team, established standards

Installers trained on the same methods we apply across our other markets.

Same equipment

JinkoSolar, LONGi, Huawei and Growatt — the same brands we install in Europe.

Long-term presence

We are building service infrastructure and support in Tanzania, not running a short-term project.
