Step 5: FAQ's

  • Q. How Many Panels Will I Need?
  • A. As a general rule of thumb, one solar panel will provide enough energy to heat a 100 litre hot water cylinder. When sizing on persons a normal rule is 50 litres of hot water per person. Take our Solar Suitability test and we will work out how many panels you need for you!
  • Q. Will The System Work At Night?
  • A. No, the system only works in daylight. At some times of the year there is insufficient daylight and that is why your system has a fossil fuel back up that will cover your needs at these times.
  • Q. Should I Clean My Panels If They Get Dirty?
  • A. There is no need to especially if you have taken out our Solar Health Check. Within the Solar Health Check we have included a full panel inspection and system check. The Solar Health Check is intended to keep your system in optimum condition and allowing you to maximise your saving.
  • Q. Surely Energy Was Used In Order To Make The Collectors?
  • A. Yes it was but the energy used in manufacturing the system will be recovered after only two years use in this country
  • Q. What Shall I Do Is Something Goes Wrong?
  • A. Turn off the electricity supply to the digital controller and the pump and then call Miller Pattison on the telephone number located in your Logbook, on page 16. Remember you are safe in the knowledge that you have the solar panel with the longest guarantee on the market today ~ 20 Years.
  • Q. Do Miller Pattison Solar Hot Water Heating Systems Cause Harmful Emissions?
  • A. I have heard that global warming is caused by carbon dioxide and other greenhouse gases. How much of these gases does my Solar Hot Water System produce?

    Your Solar Hot Water Heating System produces no emissions whatsoever. It is entirely without any discharge of greenhouse gases or other pollution.
  • Q. It Is Not Very Sunny Today. Will The Solar System Work?
  • A. Although they work best in direct sunlight, very good performance will be given in the indirect light (or diffuse radiation) of a cloudy day.
  • Q. I Am Worried About The Glycol Solution In The Heat Transfer Pipe.
  • A. Glycol has to be used to prevent the pipe freezing in very cold weather. It is not dangerous ? it is a type of anti freeze, but unlike normal anti-freeze it is classified in Europe and the USA as ?edible? and is safe for use in food. The Glycol is in a well engineered sealed system and will not leak into the domestic water supply.
  • Q. How Much Carbon Dioxide Does My System Save?
  • A. We estimate that your system will save one ton of carbon dioxide a year which is equivalent to about a large sack of soot each year. Over the life of the system each system will save dozens of tons or imagine a truck load of soot being dropped on your drive!
  • Q. Can I Improve The Performance By Adjusting The Solar Panel?
  • A. No, it would be very dangerous to attempt to do this. The panel is situated on the roof and there are no user serviceable parts inside. The heat transfer pipe is filled with a glycol solution and reaches a maximum working pressure of 600kPa. The heat transfer pipe reaches temperatures in excess of boiling point so, for example touching it, will cause severe burns. Treat it with the same caution as you would treat a pan of boiling water.
  • Q. Can I Service The System Myself And If So What Do I Need?
  • A. We do not recommend that you service the system yourself due to the high operating temperatures and technical knowledge required. It is recommended that you do some basic monitoring to ensure that there are no problems with your system. Should the monitoring not be as recommended please ring us and we will some out and resolve the problem. Basic monitoring should include monthly checks on the pressure gauge on the pumping station it should be between 3-5 bar. If no pressure reading contact us straight away our number is located on page 16 of your customer hand book also every month check visually the outside condition of the panels and see if there are any signs of leakage.

    Miller Pattison offers maintenance and servicing package that will keep your system in tip top condition.
  • Q. What Should I Do If It Snows?
  • A. Nothing. If snow collects on the glass surface of the collector it will rapidly melt. In fact the design is such that it will melt more rapidly from the collector surface than it will melt from other parts of your roof.
  • Q. Shall I Switch Off The Solar System When I Go Away On Holiday?
  • A. No - it is better to keep it on.
