solar pv

Dear Learned colleagues, my dad's 10 years old solar PV array has started playing up. It comprises 14 panels of 250Wp each fed in two strings to a Solis (?) So;arRiver 3600 inverter. Here's the chronology: 30th December 2023: Noticed no output for the previous 2 days. Weather had been awful...

Hi, I have been thinking about getting small Solar PV under 1KW peak. I recently came up on so basically I want to keep costs down as much as possible, produce enough solar for base load and may be add small cheap batter later. Does the kind of system in the video require any approvals or...

Hi, Only my 2nd post, but you were all so helpful with the first post I thought I'd have another go. I was talking previously about how I have a fairly new combi boiler (Vaillant Ecotec Plus 832) and also some solar PV and had the notion of fitting a HW cylinder as well. Since then, I've seen...

Hi, I'm hoping from some sage advice, from you lovely people. I have a Valiant Ecotherm 832 Combi boiler that was put in about 4 years ago. I'd just moved in, and the place had an old oil boiler that sounded like a jet engine, and an uninsulated hot water tank that was taking up tons of room...

I've had solar PV on my roof for 6 years now; very pleased with it, but had to repair it last week by replacing one of the 16 micro-inverters, one under each solar panel. I had bought 2 of these as spares and, after having the defective inverter replaced, now have 2 spare again. This got me...

Hello everyone, (it's my first post but I was reading posts here for a while now) The situation: My wife and I just bough a 3 bedroom semi-detached house. The house has an old back boiler in the living room behind the fire place, cold water tank in the loft and a hot water cylinder in the...

Hi, I had my system installed 3 years ago with Sunpower panels, I wanted decent quality up there on the roof. Fronius inverter is throwing up error state 447 which I read in the PDF manual as: Solar module ground, insulation error (connection between solar module and ground) It's three levels...

Hi everyone, I work for a company called Solar Plants, a Solar PV installer based in Port Talbot, South Wales. We are looking to get into contact with somebody who is in the process of building their own house, with planning permission and building plans, but that has not yet started the...

Hi All, I've been studying this and other forums for months off and on and putting all the ideas into a do it all system. I am posting my plans for fitting a heat bank to a combi boiler using a converted 300L unvented cylinder for comments / suggestions and probably ridicule. First a bit of...
