SOLAR PV OPERATION
& MAINTENANCE
Routine solar operation and maintenance, like examining your system regularly, can help prevent issues that may arise down the road. Smaller problems can easily become larger ones if not detected on time.
We provide PV system maintenance and service programs for all manufacturers — no matter who installed it.
With a comprehensive checkup plan, you can keep your panels working at maximum efficiency.
24 / 7 SERVICE

SERVICE
Our professional and licensed service team is available 24/7 to repair, inspect, upgrade, or provide operation and maintenance for any utility and commercial solar asset.
Solar panels are designed to perform for up to 25 years or more. However, a well-maintained Solar Photovoltaics (PV) installation can perform 10 to 30% better than one that is not.
Regular repair, inspection, and planned preventive maintenance of your PV system maximizes output and ROI, by minimizing downtime and system inefficiencies caused by age and the elements.
Repairs at an Affordable rate
Pinpointing and fixing problems right away enables optimum solar system output and a higher return on investment. At Pfister Energy, we select equipment with excellent product warranties so that we can often conduct repairs at an affordable rate.

SYSTEM DIAGNOSTICS & TESTING
Health checks should be performed annually to assess any changes, faults, or damage to your PV system.
Low power production impacts ROI and effective strategies for identifying and correcting problems quickly are needed.
Pfister Energy’s skilled O&M experts can help identify the cause(s) of power deficiencies and provide the necessary recommendations for PV repair.
SOLAR PANEL WASHING
A National Renewable Energy Laboratory (NREL) study found that dirty panels produce 25% less electricity than clean ones.
Factors can vary but some include air pollution, agriculture, construction, pollen, and sea salt accumulating on the panels. Most importantly, solar panels heavily soiled with bird droppings should be cleaned.
Cleaning the panels can optimize energy production — by up to 35%.
LOOSE MOUNTING BRACKET CHECK
Solar panels are mounted to your roof using a metal structure called a rack. The rack carries the weight of the panels and holds them to the roof using several sturdy bolt penetrations.
Bolts can loosen in their mounts or become missing over time from natural elements. Loosened or missing bolts can cause rack failure.
Pfister Energy’s certified electricians will inspect and make any necessary repairs to the rack to ensure your solar panels are running at peak performance levels.
DAMAGED ARRAY ANALYSIS
Heavy snow loads, strong winds, and hailstorms can cause major cracks on the surface of the PV modules.
These cracks may lead to the disconnection of cell parts which can cause a loss in the total power being generated by the PV modules.
Our licensed electricians and professional engineers utilize the latest techniques and equipment to inspect and collect data to determine the best option to repair the solar cell.
INVERTER MANUFACTURING SERVICE
Lower operational costs and achieve greater efficiency in PV plant maintenance.
Our in-house PV Operations & Maintenance (O&M) team provides field support and can operate the warranty service.
THERMAL IMAGING
Thermographic inspection of photovoltaic systems drastically improves the operating company’s return on investment.
This allows for the fast localization of potential defects at the cell and module level as well as the detection of possible electrical interconnection problems.
We will inspect under normal conditions and shutdown is not required.
