Solar inverters - where does the energy go when clipping?

@transparent 

 

Thank you for the information and advice. Maybe we could collect the panels when we go to Cambridge! 

 

Our property is in a suburban area in SE England, at the base of a hill. So unlike the typically isolated properties (that I get the sense were first movers on PV). 

It is a three story house (as we converted the loft).

@Judith Potentially our scaffolding requirement is just a small one built on the back extension. But this being H&S, the installer will have insurance and know the type of workers they use, etc. Ultimately their call. 


8kW Solis S6-EH1P8K-L-PLUS hybrid inverter; G99: 8kw export; 16kWh Seplos Fogstar battery; Ohme Home Pro EV charger; 100Amp head, HA lab on mini PC

You will, of course, check the dimensions and weight before attempting that with your van/lorry!

Most PV panels are around 1.6 x 1.0 metres, and between 20Kg - 25Kg.
They must be transported flat.

They are made to those specifications in order to be classed as a "one man lift" under Health and Safety regulations.

You can't just saw off a bit of a solar panel if the wheel-arch of your vehicle is in the way!

Our property is in a suburban area in SE England, at the base of a hill.

The difference in elevation between the top and bottom of a hill isn't significant in comparison with the height of thunder-clouds.

I can assure you that all houses with vertical wires connected to solar panels on the roof will be subject to the same physics of electro-magnetism.

I would agree that houses at the top of a hill are preferentially more likely to actually suffer a direct lightning strike.

However, all houses in the area would still be affected by the ground-wave of course.

The advice to readers here is this...

Unless you do actually understand the physics sufficiently well to make calculated choices in the selection of anti-surge devices,
buy the best you can afford in order to protect your investment in solar power.

 


Save energy... recycle electrons!
