Poor November for Solar Power UK

November 2015 has been the worst month for solar power generation since we got our panels installed in 2011 with a paltry total of under 90kWh.


However the year as a whole is still going well with over 3100kWh generated from January to November 2015. With a reasonable December we should still hit over 3200 kWh for the year.


Fortunately we don't have the shading issues experienced by the solar panels below which probably generated virtually nothing over the month.

Replace Drive Belt Electric Plane Motor Runs Blade Not Turning

A common fault with electric planes is that the drive belt can snap meaning that the motor runs yet the cutting blade doesn't rotate or turn. The part is very cheap and is very easy to replace as this video shows. The cost was under £5 and the replacement took a few minutes, in fact it took longer to video than to actually do the belt replacement

August 2015 Worst Solar Month

After recording the numbers for August 2015 it's clear that it has been the worst summer month for our solar panel electricity generation since we had our solar PV panels installed in 2011.

The total electricity generated was only 307kWh compared to 366kWh last year and 405kWh in 2013. I think the combination of both cloudy days and rain has caused this but on the flip side July and June 2015 were very good months for electricity generation.

May 2015 Solar output

The data for May 2015 has now been loaded to the site. Another good month and 2015 has so far been very good for solar PV electricity generation.

Tesla Batteries for Home Electricity Storage

It looks like the dream of being able to store solar electricity to use overnight might be coming a step closer to reality.

Tesla have announced new battery technology that may start to make it viable.

Perfect Day for Maximum Solar Power Generation

Today has been one of those spring or summer days that is ideal for getting the maximum power from your solar panels but not for being outside.



Perfect Day for Maximum Solar Power Generation

The sun has been out all day with pure blue skies but the temperature has been fairly low with a cool breeze too. These are perfect conditions for getting the maximum power generated from solar panels as it keeps their temperature down which improves electricity generation.

When solar panels get hot their efficiency drops so they produce less electricity. On a day like today with a cooler breeze and lower temperatures we can get over 21kWh of electricity produced which equates to over 7kWh per kWp of solar panels.

No snow this year so no loss of production from panels being covered
