below is a really handy video explaining the principles of solar thermal hot water production, it is produced by an American company which it why it features their details at the end.
If you have ever left your car parked on a sunny day and returned to it an hour or so later, you will have experienced solar heating as the car will be considerably warmer than the outside temperature.
Solar hot water is carbon free, sustainable and good for the environment.
Solar collectors are usually fastened to the roof, so that they are out of he way and receive the full benefit if the sun. A mixture of water and glycol circulates through the collectors and it is warmed by the sun (in the same way your car was). Collectors can be as simple as an old radiator painted black or as sophisticated as evacuated tubes, the latter are more efficient collectors but more expensive.
Solar thermal systems will not provide all of your hot water throughout the year but 60% and above is a reasonable expectation. The life expectancy of solar panels is well in excess of 20 years.
Pleased to announce we will be joined by @RichardBlyth7 of @RTPIPlanners and @Dom_Hogg of @Eunomia_RandC at our next #COVIDー19 webinar, exploring how the planning system could be flexed to accommodate #solar projects at risk of overrunning.
In our next #COVID19 webinar we will explore emerging challenges, including the continuation of critical maintenance on #solar sites, how DNO work on new connections will be impacted and to what extent knock-on effects on future projects can be mitigated.
