Proactive maintenance

We’re on-call every day of the year, including weekends when we have people on stand-by. Our proactive maintenance packages include regular inspections and annual services.

We offer regular inspections for solar and will work with you to decide the most suitable maintenance programme be it every month, 3, 6 or 12 months.

During inspections we’ll check everything on site including;
  • panels
  • security fence
  • inverters, including a visual inspection of the AC/DC cabling
  • on-site buildings
  • medium and high voltage facilities
  • mounting structures
  • grounds
  • site cleanliness

Annual service plans

Full annual inspections. Each year we’ll send a team of O&M technicians to your solar installation to perform a full service. We’ll check everything and record details of the service in your log book … and we’ll email you a report as soon as we’ve finished on site using our special reporting app. 

 You’ll be able to see before and after pictures along with a summary of the visit. If our team find anything that we think will increase the performance of your solar farm we’ll make recommendations, we’ll always have an eye out for things that might help you maximise generation.

A full service will include (but is not limited to);

The grounds Including your fencing, the grass and checking for any shade creeping in from over hanging vegetation
PV modules All in top working order, clean, undamaged, not in shade, checking all the electrics
Mounting structures All in good condition

Land management plans

Our commitment to protecting the environment has seen us raise staff awareness and incorporate specific measures into the daily operation of our business. Natural Generation has been accredited with the BS8555 environmental standard and performance, something we review regularly.

We ensure all equipment is maintained in good working order and fitted with the appropriate silencers, mufflers or acoustic covers where applicable and the movement of vehicles to and from site is controlled.

We aim to leave sites cleaner than we found them. We take every piece of litter away and dispose of all packaging separately – it’s all recycled and dealt with properly.

We are committed to continual improvement of our environmental performance and in order to do this we will:

Meet and, when possible, exceed all regulatory legislative requirements
Prevent pollution at all times
Set objectives and targets to reduce the impacts
Reduce unnecessary journeys through an effective management system
Seek to operate and maintain our equipment to the highest possible standards
Encourage the implementation of energy conservation measures alongside renewable energy systems
Make this policy available to all our staff, contractors and to the public
