How can we help?

What Can You Ask Us About?

You do not need to know the technical language. Tell us what the system is doing, include any warning code you can see and we will help point you in the right direction.

01

Solar Performance

“Why is my solar generating less than usual?”

02

Inverter Fault Codes

“What does this red light or error code mean?”

03

No Generation

“My solar has completely stopped producing electricity.”

04

Battery Storage

“Why is my battery charging or discharging differently?”

05

FIT & Export

“Will this change affect my Feed-in Tariff or export payments?”

When online advice is not enough

Some Solar Faults Need Proper On-Site Testing

Some questions can be answered from the information you provide, but no remote assessment can electrically test your system, inspect hidden wiring or confirm that an installation is safe.

Remote advice is general guidance only and does not replace professional testing or inspection where an electrical or equipment fault is suspected.

Contact us directly if:

  • The solar system has stopped generating completely
  • Fuses or circuit breakers repeatedly trip
  • A persistent inverter fault code will not clear
  • You smell burning or see visible heat damage
  • You suspect an electrical or fire-safety risk
  • There is damaged DC cabling or connectors
  • The panels or inverter have suffered physical damage

    Frequently asked questions

    Ask Mr Solar FAQ

    Can you diagnose my solar system from a message?

    We can often narrow down the likely cause from the symptoms, fault code, monitoring screenshots and equipment details, but some faults require electrical testing or an engineer on site before a diagnosis can be confirmed.

    Should I reset my inverter?

    Only follow the manufacturer’s published user restart procedure. Do not open the inverter or disconnect solar DC connectors.

    Can I ask about a system Mr Solar did not install?

    Yes. Yes. We provide professional repair and Rescue support for suitable systems installed by other companies as well as our own installations.

    Can I ask about Feed-in Tariff or export payments?

    Yes. We can explain general FIT, generation-meter and export issues. Specific metering or compliance questions may require us to review your system paperwork.

    What information should I provide?

    The inverter or battery make/model, exact fault code, postcode, when the issue started and what the monitoring app is showing are all helpful.

    There are a few reasons why your solar inverter might not be working. Here are some of the most common causes:

    If you think your solar inverter might not be working, there are a few things you can do to troubleshoot the problem. First, check to see if there is a power outage. If there is, you will need to wait for the power to come back on before you can troubleshoot the inverter.

    Solar Home

    If there is no power outage, you can check the wiring between your solar panels and your inverter. Make sure that all of the connections are tight and that there are no damaged wires. You can also try resetting the inverter by turning it off and then back on again.

    If you have checked the wiring and reset the inverter and it is still not working, you may need to call a solar technician to diagnose the problem. The technician will be able to check the inverter for any faults and make repairs if necessary.

    Here are some tips to help you prevent your solar inverter from not working:

    By following these tips, you can help to keep your solar inverter working properly and avoid any problems, If for some reason you may need our help as we are the best solar panel installers in Norwich please use the contact form below and some will be in touch about how we can help you.

      Solar Photovoltaic cells are often advertised as an investment that saves you money in the medium/ long run. Let’s consider a a house in East Anglia, The average home electricity power use is;

       2,900 kWh per year, priced at 28.34p Per KWH, £822 Per year electricity charge for metered electricity. (According to OFGEM) 

      Now, the house has a standard concrete roof, tiled, facing South, no Shading, standard 

      4.0kw (11 Solar Panels) generating 3,600kwh Electric per year; 

      2,900 kwh (we will use electricity per year )x 28.34p = £821 Per Year 

      4.kw Solar PV cost £4,995, pay back 6 years + Added re-sale value to the property + added protection of future increases in electricity costs. 

      If you have fixed your tariff until 2023 in favour of potential future savings as energy sky rockets in price, the maths looks like this, 

      2,900 kwh per year x 40.0p = £1,160 cost of 4.kw Solar PV £4,995 pay back 4.3 years pay back + Added re-sale value to the property + added protection of future increases in electricity costs. 

      we can add electricity storage systems, divert solar energy to the hot water emersion if you have a tank for hot water. The above is a simple example and reflects good conditions, so tell us about your situation and we will do the maths for you to check.

      Solar panels work by converting sunlight into electricity. They are made up of photovoltaic cells, which are made of semiconductor materials like silicon. When light hits a photovoltaic cell, it knocks electrons loose from their atoms. These electrons then flow through the cell, creating an electric current.

      The amount of electricity that a solar panel produces depends on the amount of light it receives. Solar panels work best in direct sunlight, but they can also produce some good electricity on cloudy days.

      Solar panels are a clean and renewable source of energy. They do not produce any emissions, so they are good for the environment. Solar panels are also a relatively affordable way to generate electricity.

      Here is a more detailed explanation of how solar panels work:

      1. Sunlight hits a photovoltaic cell.
      2. The sunlight knocks electrons loose from their atoms.
      3. These electrons flow through the cell, creating an electric current.
      4. The electric current is then collected by wires and carried away to be used.

      Solar panels are made up of many photovoltaic cells. These cells are connected together in series, which means that the current from each cell flows into the next cell. This creates a larger current that can be used to power appliances or to feed into the electricity grid.

      Solar panels are a great way to reduce your reliance on fossil fuels and to help the environment. If you are considering installing solar panels, there are a few things you should keep in mind:

      • The amount of electricity that a solar panel produces depends on the size of the panel and the amount of light it receives.
      • Solar panels can be affordable to purchase and install, but they can save you money on your electricity bills in the long run.
      • Solar panels require very little maintenance.

      If you are interested in learning more about solar panels, there are many resources available online and at your local library. You can also talk to a solar installer to get more information about your specific needs.
