Solar heating panels, yield, installations, and installers
Thermal refers to "heating-generation" plates. Learn about traditional solar known as flat-plate solar panels. These heat water and reduce immersion coil usage. Your home's heating system will operate more efficiently while extending boiler life. From March to October, your traditional boiler won't be necessary. Solar heating panels heat due to short-wave radiation converting to long-wave on impact.
"Our solar heating system heated all the hot water we could ever need in summer - plenty to fill our big double corner bath - and made a huge difference in our electric water heating bill even in winter months, it might only heat the water to tepid, but I'm seeing winter energy costs are much less."
Mr. Atkinson, Barnstaple.
The basics.
The best solar thermal technology includes a patented Low E glass. These use a unique 'low-iron' glass formula that has reduced reflective properties and increased absorption. The reason is heat retention and production at lower outdoor temperatures. Each panel is just like a thermos flask. Once the heat is in, it becomes trapped.
The science bit.
A popular solar technology before the advent of evacuated tube systems:
- A solar heating system heats up due to the sun's short-wave radiation output converting to long-wave radiation. This process creates heat.
- The variable speed controller circulates based on temperatures within the panel.
- The pump circulates a Glycol solution through the hot collector and backs down through a heat exchanger.
- The system automatically shuts down when not in use or when the collector temperature is lower than the cylinder.
What about combi boilers?
Combi boilers aren't possible in most cases. We would need to re-install a hot water tank. Most homes with Combi's won't have the space to install a hot water tank.
Can I install solar heating myself?
Yes, it is possible to self-install a DIY solar kit or work with a local tradesperson.
Is there a danger that it could get too hot?
The system may never rise above 85° Celcius. Low-E (low iron) glass prevents heat loss. Low-iron glass has less reflective and increased absorbing properties.
Can you upgrade my hot-water tank?
Older 'copper' hot water tanks run exceptionally inefficiently, especially after many years of use. Limescale will reduce performance even further. When installing a solar heating system, it's essential to establish an efficient tank to get the most out of your system.
Do I require planning permission?
Listed buildings, conservation area homes, and national parks may require permission. Please consult with your local planning officer.
How long will I be without running water?
Normally only 4-5 hours.
Do solar heating panels work on cloudy days?
This question depends on the density of the cloud. In average cloud density, solar panels use passive energy. With dense cloud cover, probably not.
