I guess you haven't heard of Hinkly C?

Being built by French EDF.

EDF had to be bought and subsided by the French government

Because it stuffed up building nukes and nearly caused Toshiba to also collapse.

I was doing a bit of research on balcony #solar and suddenly remembered I have two very small panels and a portable power pack and now I'm thinking I should do a little experiment.

Grid batteries are making a killing. A few years ago they almost did not exist (because of the price). Now they are taking over other sources of energy for peak supply. This means PV+battery just became a 24h/day energy source. With this replacement dynamics #dunkelflaute will not be a scary thing in a few years.

Every month when I get my power bill I'm thankful the previous owner of this house installed a rooftop photovoltaic system. Last month was finally sunny after many cloudy months and the panels were zipping. Electricity is 40 cents per kWh here so every free watt is a gift. My system is fairly small and has needed maintenance and repairs but it's saving me at least $100 a month.

Coal pollution is cutting solar power output worldwide, study finds

New research led by the University of Oxford and University College London (UCL) has revealed that pollution from coal-fired power plants is significantly reducing the energy output of solar photovoltaic (solar PV) installations, particularly where these are expanding side by side. The findings have been published in Nature Sustainability.

It's 7am local time here and the panels are producing 270Ws even though the sun has only just cleared our neighbours house, it means that we are already running on solar and charging the little battery.
We aren't in a position to move our heating to electric yet (lots of reasons) so our electricity consumption is fairly low.

The good news is that the panels have not fallen off overnight!

Nuclear is the answer, if you ask what is the very slowest to build and most expensive by far electricity.

Renewables and batteries are the cheapest

@brianb

Use proper solar connectors, from reputable firm. Use proper crimp tool for that connector.

Use proper solar cables. Same as the panels EN50618, 60228

Here in Australia, land of rooftop solar.

You need to be both a electrician and do a special course to add grid connected systems. Need special course just to design them.

Research solar system failures and bad installs. See Solar good, bad ugly.

So one thing to keep in mind is you are dealing with DC voltage.

DC voltage does not like to be connected and disconnected.
It will ionize the air and create and sustain big arcs.

DC switches have really heavy duty contacts and much bigger distances between poles, compared to ac switches.

AC goes through zero 50 times a second, so less arcs.

Do not disconnect connectors under load.

With high voltages from combining panels, high currents, it is like welding. Will melt metal.

Coal pollution is significantly reducing the output of solar panels, major study finds

Study by University of Oxford and University College London finds that coal pollution is significantly reducing the energy output of solar PV installations.
