Solar Power & Battery |

|
Return on Investment (ROI) calculated... ...a comparison with investing the same money in a pension. |
|
|
Outside of financial Return on Investment, what is my experience of installation and the 1st 6 months of operation? Eg was it reliable? Would I have done anything different? |
|
|
Why I chose Octopus' Flux tariff? How did the sign up process work out? How did I schedule battery charge and discharge? |
|
|
Includes a couple of points that I wish I had known before signing the contract |
|
|
How did I select from the 4 quotes provided? What factors other than price did I consider. How did the numbers in the selected quote impact my ROI estimate? |
|
|
This was written before I had quotes from solar providers. Solar #7 has better data and a more developed ROI model, but, I still think, the risks listed here are about right. |
|
|
Our house does not face South... ...So I assumed was not suited to solar panels. The Energy Saving Trust website calculator put me right (in under 5 minutes) |
|
Smart Meter |
|
|
Will my smart meter ever work?... ...see what finally did the trick |
|
|
It's in the news - smart meters just don't work very well... ...my rant on how to fix the issue - no magic nor a complete technology revamp; just good engineering and practical management - read more here. |
|
|
Another rant - more focus here on how Octopus/installers could do a better job with the (limited) options that they have... ...also, what is the impact, in £s, of a smart meter not working? |
|
|
Solar system installed and working... ...now the smart meter has stopped working - 1st part of the saga |
|
Save Money & more comfort |
|
|
Turned out to be more work than I expected, but instant impact in £'s saved and comfort... ....this is what I learnt along the way. |
|
|
Smart Heating Controls - My Experience with Honeywell Evohome - Part 1 |
User perspective of 3 years living with Evohome... ...mostly good but some lessons if you are considering Evohome or another smart heating system. |
|
Smart Heating Controls - My Experience with Honeywell Evohome - Part 2: More Technical Points |
More technical perspective of 3 years living with Evohome |
|
Not a massive job, and not expensive, but a good payback. |
|
|
Easy and low cost: good for comfort, but probably only a weak financial payback. |
|
|
This is an intriguing add on to our gas boiler... ...does it save money? What is the impact on home comfort? |
