Solar PV Health Check

Solar PV is the most cost effective way of generating power and has become a popular investment for PV plant owners small or large wanting to reduce their energy bills.

Solar PV is the most cost effective way of generating power and has become a popular investment for PV plant owners small or large wanting to reduce their energy bills.

As the popularity has increased year on year we have experienced a large volume of calls from owners wanting a health check on their panels to ensure that they are maximizing return on their investment.

We have experienced firsthand inverters that were not effective and not producing, therefore resulting in a complete loss of revenue for the Plant/PV owner.

Once your solar PV has been installed and is effectively producing electricity, it’s vital that you keep your investment serviced to ensure that all components are functioning. This will not only ensure that you are capitalising on your investment but will also help to diagnose issues quickly and efficiently.

Our experienced and knowledgeable engineers have access to state of the art measurement and communication equipment which enable them to check the IV curve of the panels, in addition to carrying out insulation resistance tests of the DC cabling connecting your panels to the inverter.

This specialist equipment enables our engineers to diagnose and rectify problems the owner may be unaware of.

We have our own state of the art thermal imaging cameras which will highlight issues with the solar panel diodes before they become detrimental to the efficiency of the installation.

This equipment is also used to examine the cabling and the inverter to detect if there are any hotspots within installation which will require attention to enable the system to perform efficiently.

This is the most crucial element of the installation where the DC power form the panels is transformed to usable and exportable power.

Here at HIT Energy Services we are on hand to offer advice on how best to diagnose any issues you may be having with you installation, be that at your PV plant or on your rooftop.

We offer a short term solution for your long term investment and not only help to protect your panels but also help to protect the future of your investment.

Once we know the your system is performing well we can then look at installing our bespoke PV monitoring system called the SHES Guard.

Our engineers have the experience and state of the art equipment at our disposal, we work to ensure that all service levels are met no matter the deadline.
