Professional Site Evaluation

It includes an electronic compass and inclinometer enabled to measure roof pitch and azimuth

We will come to your home or office to prepare an assessment of the PV capabilities at your site. A detailed report will be provided showing estimated annual performance.

 


Solmetric PV Designer Software

PV Designer software enables you to quickly and easily: draw a roof outline, specify set-backs and keep-out regions, incorporate SunEye shade measurements at specific locations on the roof, drag-and-drop modules, size strings, check inverter limits, and calculate the AC energy production for your system. It includes extensive world-wide databases of modules, inverters, and historical weather. You can easily try different design scenarios and compare their AC kW-hr outputs side-by-side to identify the best design. Results can be exported in a PDF format and printed or emailed to clients. The software is designed for residential and small commercial systems.
