Solar PV Upgrades or Replacement Inverters

There are many Solar PV systems that are coming up for 5 years old that were installed at the early high FiT rates. Those systems’ inverters are nearing the end of their warranty & some are beginning to fail. 

The obvious option is to replace the  inverter with another string inverter, however we recommend installing a SolarEdge Inverter with Power Optimisers as this will provide the following benefits:

  • Increase in Revenue – SolarEdge Power Optimiser technology has been tested & proven to increase generation.
  • Live Monitoring – Access to individual panel monitoring via your computer, tablet or phone allowing full visibility of the performance of your system including Solar generation, energy consumption & export data.
  • 20 Year Warranty – SolarEdge Inverters come with a 12 year warranty as standard but as part of the upgrade we extend it to 20 years and SolarEdge Power Optimisers come with a 25 year warranty. 
  • Future Proof – along with our 10 year workmanship warranty, the core item of the system is guaranteed for the rest of the FiT scheme.
  • Battery Ready – with the addition of  SolarEdge’s StorEdge interface the system can be further enhanced with the ability to add a TESLA PowerWall. 
  • Firefighter Safety – SolarEdge is one of the very few inverter technologies that have been passed as Firefighter safe.
  • Panels – as part of the upgrade whilst adding the optimisers, the panels will be cleaned & all connections checked
  • Full Health Check – we will also check all electrical wiring & isolators. 

Stratford Energy Solutions are both SolarEdge & Tesla certified so even if your system appears to be working let us upgrade it & start increasing your revenue from your Feed-In Tariff.

Solar Panel Maintenance

Although Solar PV systems are extremely reliable they still require maintenance. Residential or commercial systems are no different, although down time of larger systems will have greater financial implications.

Regular maintenance can be client led with monitoring of the system, visually checking & potentially annual cleaning of the panels.

We are able to offer a full range of solutions to help maintain and keep your Solar PV system working & producing energy at the optimum level.

If you do not have a current maintenance package in place, your system is out of its workmanship warranty  or was installed by A N Other installer we are able to assist. Please call for details – 01789 262411.

Annual Maintenance Package – every system and client has different requirements. Service can include:

  • Annual cleaning to keep efficiency maximised, especially where bird soiling or atmospheric pollution has degraded the surface of the panel.
  • Visual inspection of all panels.
  • Remote monitoring with pro-active alerts.
  • Module string tests.
  • Inverter system checks.
  • Electrical inspection to include cabling, isolator & distribution board.
  • Generation Meter check.
  • Energy geberation analysis.
  • Voltage and current check.

Any faults or potential issues will be highlighted & repaired or corrected if required.

SunPower Solar PV Hospital with SMA Inverters out performs expectations, Leamington Spa, Warwickshire

Installed in June 2014 for Community Energy Warwickshire the Solar PV system at the Rehabilitation Hospital in Leamington Spa has out performed expectations. 

It had been estimated that the system would generate 43,000kWh of electricity per annum – 865kWh/kWp. However, with less than 2 years since installation the system has generated over 100,000kWh of FREE, Green electricity – over 1,006kWh/kWp.

The system comprises 152 high efficiency SunPower E20 327w panels with 3 x SMA TriPower inverters all monitored via an SMA Webbox.
