Performance Update - June 30th
MENU

Surface Power solar thermal systems demonstrate their outstanding performance over existing solar hot water technology on a daily basis.

In this performance update, we will discuss the following:

  • A comparison of 2 solar vacuum systems in cloudy weather.
  • A list of working energy centres around Ireland.

(NOTE: WE DID NOT INCLUDE A SOLAR FLAT PLATE COMPARISON AS THE DAY WAS CLOUDY AND THIS WOULD BE AN UNFAIR COMPARISON, WE ONLY INCLUDE FLAT PLATE SYSTEMS WHEN THE WEATHER IS BRIGHT SO THEY CAN PRODUCE AN ENERGY COMPARISON)

TODAY'S WEATHER

Today's solar factor: Average: 25%. What does this mean ? The solar factor is a measurement of the PERCENTAGE of solar energy delivered as being recorded by a reference grid connected photovoltaic system at the same location. i.e. (a clear sunny blue sky day will deliver a maximum value of 100% at noon).

TODAY: SOLAR FACTOR: AVERAGE 25%. (CLOUDY but no rain)
PERFORMANCE COMPARISON EXAMPLE FROM TODAY

SYSTEM 1 - (EU manufacturers name withheld)

 System 2 - Surface Power SP501

This is a comparison of 2 solar vacuum systems, you can clearly see the difference with the unnamed system unable to get above the cylinders working tank temp. It is clear the Surface Power system is capable of significant power even in poor weather. This is why our long life professional solar systems work exceptionally well in winter and with solar central heating systems.

SUMMARY: this (unnamed) solar vacuum system has been unable to raise the working temperature of the cylinder due to cloud. It has produced little performance today (by 2pm) SUMMARY: this Surface Power SP501 system has performed strongly with an average delta T of 8C recorded. The working temperature of 37C was raised to 64C by 2pm and the system is still heating at 2.2kw of solar.
* Weather - cloudy and rain due in the afternoon, (all systems data logged)
