He did indeed David!, only excuse i can muster was a was severely

Quite, you're never going to get a kW of power out of a 350W panel, but for 
about 7 months of the year, you'll get over a kWh of energy.

It was something like 340 kWh in 365 days, you'll get more of it in longer days 
of summer and very little of it in winter.

> Or is it just the daylight hours whatever they might be?..

clearly none of it will be outside daylight hours!  but the lower/weaker summer 
sun means even less that just the shorter day length.

e.g. in each of december and january you'd expect 12kWh per month so 0.4 kWh per day

but in may, june and july you'd get 41 kWh per month, so 1.3 kWh per day

He said kilo Watt hour per day, not kilo Watt.

A kilo Watt hour per day is on average (1 kilo Watt * (1 hour / 24 
hours)), so on average 1/24th of a kilo Watt, averaged over 24*365.24... 
continuous hours.

That "just under" 1 kW over the year average is that in a 24 hour period 

Or is it just the daylight hours whatever they might be?..

Over the course of a year (don't know where charlie is based, so assume 
midlands) a 350W panel will average under 1 kWh per day throughout the year, can 
offset what you'd buy at 52p, rather than expect to sell it for 5p since you'd 
need a certified installation for SEG tariffs.

A G98 compliant micro-inverter is the minimum you can fit, doesn't need to be a 
certified installation (get a sparky in, or look into it and DIY) you don't need 
to ask permission from the DNO to install one, just need to notify them you 
will/have done so.

&pound;200 for the panel, &pound;150 for a micro inverter, plus some cables and isolators, 
to save &pound;170 off the electricity bill?  You decide ...

It's only complicated if you want to sell AC back to the grid. Take a 
look at "inverter chargers" with built-in transfer switches.  Grid up
charges the battery, grid down transfers local load to inverter using
the battery as backup. Grid not connected then, so no need to sync 
and no backfeed problem.

When you do this you'll _really_ notice the standby loads on the battery.

Not bad thinking but the inverter could not be very simple - it would
need to sync perfectly to the mains already running..  shut down in a
power cut, restart etc. Then there are always "the regulations" ! C+

I knew somebody who did that annually.  He had a standing arrangement 
with a villa owner in the Algarve to live there from December to March. 
The villa owner was happy to let him and his family live there cheaply 
because he could show his insurance company that the villa wasn't 
unoccupied and able to be burgled, and that gave big discount on the 
premium to be paid.

Unfortunately he died 2 years ago so it no longer happens, but before 
that he had 6 years of very cheap winter holidays with water and gas and 
electricity all turned off in his own house.

Do you know of any talking ones or ones that work with a smart phone?
 I do have a talking smart meter display of course, but its hard to  be sure 
everything is isolated to measure stuff, even the meter itself uses power.
