Solar Maintenance and Aftercare

Help is at hand with E.ON Care Solar 

Do your solar panels need some care and attention?

Our experts are here to provide solar support. We’ll give you advice on the best ways to maintain your solar panels, so you can continually keep them in a good state of repair. 

How can we help?

We have a team of experts who can offer advice and support if you’re concerned about how much solar power you’re generating or if you have a problem with your solar system.

As one of the only energy companies offering all our customers renewable electricity, helping you make your difference is important to us too, whether you’re an E.ON Energy customer or not. 

Do you have a problem with your solar system?

If you are concerned about your solar system, there are a few things you can check for yourself, that may get it running again.

Is your electricity connected?

Power is needed to your property for your system to be able to work. If you have no electricity supply or if you have a prepayment meter with no credit, your system will shut down and not generate.

Has your switch tripped?

Your system will have its own trip switch (RCB) on the fuse board and should be labelled for easy identification. Check this has not tripped. It should be in the “on” position.

Are your isolators in the ‘on’ position?

Isolators are on/off switches that allow parts of your system to be disconnected for maintenance purposes. Check that all isolators are in the “on” position.

Is your system underperforming?

If you have trees or structures that cast a shadow on your panels, at any point during the day, you may be generating less electricity than you could. If you are not able to remove the cause of the shading, you may benefit by upgrading your inverter to one that works better with partially shaded systems.

How do solar panels work?

Your solar PV (photovoltaic) panels capture the sun’s energy and convert it into electricity for your home using an inverter. Your home will use this power as you generate it, then you’ll import any extra you need from the grid. Any extra you generate will go back into the grid, or some may be stored in your battery, if you have one.

How to make the most of your solar panels?

Unless you have a battery, your free solar electricity cannot be stored and used at other times. 

To make the most of your solar electricity use it at the time it is generated.

  • Use your electrical appliances during daylight hours, when the solar panels are generating free electricity.  Top Tip - set a 24-hour timer so that your washing machine and dishwasher come on even when you are out. But make sure your appliances are electrically tested and safe to leave unattended. 
  • Spread the use of your appliances throughout the day so that you maximise your free electricity supply. If they are all on at the same time you might use more energy than your solar panels can generate and so, you’ll end up paying more than you need to.

How to look after my solar panels?

Your Solar PV system is designed to work for many years with minimal maintenance.  But, it’s still a good idea to keep a close eye on your system and how much electricity it’s generating.

If you’re not sure you could make a note of your readings from your smart generation meter every week and take a note of any  weather conditions at the time. You’ll soon come to understand how much electricity you can expect to generate in different conditions and at different times of the year.

Sometimes little things like excessive bird droppings can drop your generation.  You’d be able to see this.

There are companies who specialise in this work and can arrange for a technician to come out. There will be a charge for this, but they should let you know the costs before carrying out any work.

Frequently asked questions

What is a Feed-In-Tariff?

The Feed-in Tariff (FiT) scheme, was introduced by the Government in April 2010 and finished in March 2019. It was designed to help generate more renewable energy across the UK. Under the FiT scheme, the owner of an approved solar power system will get paid for all the electricity the solar panels produce. The is managed on behalf of OFGEM by a designated FiT Administrator.

What happens if I want to move home?

If you are receiving Feed-In Tariff payments, you will be registered as the asset owner with your chosen FiT Administrator. When moving home, you can either have an agreement with the new owner so that you continue to be the asset owner (and receive the FiT payments) or you will need to contact your FiT Administrator to arrange a transfer of ownership.

Will my electricity meter work differently?

Your electricity meter will continue to record the electricity you use, but it may tick over at a slower rate when your panels are generating electricity, it may even stop for a short space of time if you're generating more than you're using.

What is a Rent-a-Roof Scheme?

This is when a company installs the system for free (or nominal fee) but retain ownership of the asset so that they can claim Feed in Tariff payments to recoup the cost of installation. The home owner will have signed a lease with the company running the scheme, which effectively rents the roof to them for a period of up to 25 years. Land Registry have a copy of the lease, as it is attached to the property.

What is an MCS Certificate?

MCS stands for 'Micro Generation Certification Scheme', it’s a certificate to confirm that your installation has been enrolled within the Micro Generation Certification Scheme and has been installed by an accredited MCS certified installer. The MCS is the independent Government backed scheme that certifies micro generation products such as solar photovoltaic panels
