Including permitting, grid connection approval, and equipment lead times, the full project timeline is usually 6-12 weeks. Commercial and utility-scale projects take significantly longer due to land use, environmental, and grid impact assessments.

Local installers in Austria typically offer faster response times, better familiarity with regional permitting, and stronger after-sales support. National companies may offer scale advantages, broader equipment options, and standardized warranty terms. For most residential and small commercial projects, verified local installers deliver the best overall value.
