    Solar installations roof work

    Possibly a silly question, I would like to do solar but I really don't like being on roofs, and don't fancy cutting roof tiles and all that stuff. Is it possible to have someone else install the panels under supervision and then do the electrical connecting and setup myself? Thanks, Chris.

    After some advice please TPN supply with single phase PV install

    Hi Guys I don't much about PV being honest, we normally just leave space on DB for the PV installers to do their thing. Sometimes having to run a cable to the inverter location. Never really hear anything about it after that. Apart from recent new build which has TPN supply/ DB and PV was...

    Solar Panels: Inverter Shutdown and Static Generation Meter Reading

    Hi, I have solar panels installed on my home. The reading on my generation meter (Geo Emlite M15) hasn’t changed in several months. The meter displays a steady green “STS” light and a flashing red “NWK” light. I’ve confirmed that all breakers and isolators are switched on. The solar inverter is...

    Have I wired this solar correctly.

    This is at the mains unit end after a complete refurb. I've come from the inverter in the loft into the isolator, then into the left side of the meter and then the right side of the meter into the RCBO. The solar guys did all the loft work but had left site before I'd replaced the mains, that...

    Domestic solar and 3-phase

    A customer has just bought a property. 3 bed semi, 'normal' size, but with a fair bit of land. 60A supply. The main house will be space heated with solid fuel, but otherwise relies on electric for cooking, water heating etc. There will be a 2 bed static park home about 30m from the main...

    Tariffs, batteries, and solar. How do you select? and does it matter?

    My off-peak tariff has ended, and for a few days on a standard single tariff until I change supplier, but cost has not risen much? Changing because the supplier I have has dragged their feet for a year, and still no payment for export. But I have been charging batteries overnight, then they...

    Can Solar panels cause tripping when isolated

    Anyone know if its possible for a rooftop solar array to cause an RCD trip even when the solar circuit is isolated at its rotary isolator ? I've had no dealings with solar atall so wouldn't know . The solar circuit is in a split load RCD board. I'm assuming the solar install was bonafide as its...

    Do you think then solar boom is over for existing properties?

    I think I'm right in guessing that most of the grants have stopped long ago when it comes to adding them to your existing property? So does that mean the solar boom a decade back has fully stopped these days? Any grants and things to add them to new properties? Or would you just be buying a...

    Battery Charging 12v Battery with Solar Panel?

    I use a small 12v 1.5w Solar Panel to charge my engine battery, quite often it's not powerful enough and the battery loses charge. If I buy a bigger one say 30w, would that still trickle charge (albeit faster) it, or would it damage it? TIA

    Software for electrical / solar photovoltaic systems design

    Good Afternoon Does anyone know an UK / Brit Software for electrical / solar photovoltaic systems design? French software is starting to get small for the KWpeak that I´m designing and maybe we could have an UK alternative. If not, does anyone know an EEUU electrical design software? Regards

    which is less dangerous DC 123V/20A or 50V/50A?

    which is less dangerous DC 123V/20A or 50V/50A? or does it not matter at all? context is an 85 foot run on bedrock between solar panels and battery house. i've researched and gotten no definitive answer, just confused. i'll probably end up putting this wire in rigid bonded conduit anyway but...
