Photovoltaic System Inspections
All manufacturers recommend a complete inspection of photovoltaic or solar  power systems before they are put into service, unfortunately most installing companies do not have the experience or knowledge to perform a comprehensive exam of your entire system.

We can perform the following services during an inspection of your photovoltaic system

Load Analysis in order to make
sure your array and equipment is large enough for the loads which will be attached to the system.

Electrical System Inspection in order to make sure there are no hazards or additional resistance which could increase operational cost and cut efficiency.

Solar Array and Equipment Inspections in order to make sure your systems is delivering what you expect.  Loss of efficiency will cost you money and will add up to a large amount over the life of your system.

Solar Array Shade Analysis in order to make sure you are maximizing the peak sun isolation each day which in return will deliver the best bang for your buck.

Structure Conditions as related to the solar power system installation to make sure no roof leaks exist.  Systems designed by companies with extensive experience in the installation of the many different power source systems will always deliver product with increased longevity.

Operational Testing  observing different conditions and operating specifications:

  • Array temperatures checking for proper clearances which effect efficiency.
  • Current being delivered thru system devices insuring ratings of installed equipment is large enough.
  • Voltage levels, both DC and AC sources
  • Temperatures at all wiring terminations

We leave nothing to chance!

Photovoltaic or solar power systems can be installed to both save and sometimes make you money as well as reduce carbon emissions.  However conservation as well as the efficiency of your system will determine the success of your investment.  Employ a seasoned electrical contractor with a complete understanding of electrical theory.
