Plumb it into the MVHR.

Except the MCS rules. Some suppliers may push the limits a bit, but not that much.

Then they have not charged you for anything else. That is not a bad quote/price paid.

Geting back to the size of housing, almost. Rather than cram people into smaller and smaller places, why don't we cram workers into a smaller footprint. Why don't we build high rise, combined, hospitals, shopping centres, offices, schools, resturants, cinemas, car parking, all the daily stuff. Could surround them with nice fields, woods, lakes, seaside views etc. Then put the houses in a ring around them. Would make for easy transport, not chris crossing town to see a mate in hospital, after picking the kids up, before a night out. It is all in one place. Maybe some heavy industry would have to be pushed out to one side, but that is no worse than today. And just think, if a resturant/food court was on the top floor, how good the view would be. Then, on the roof of that, could be a sports field. Great fun when someone hits a six. Javelin would be interesting, as would archery.

@JSHarris is the one for working out the latent heat of evaporation.

Hunt around and see how much a battery pack and invert/charger for it is, then see if your quote still makes sense. I would think, though not been involved in this for a few years that a 6 kW system would be around £10,000. Maybe a bit more, or less depending on how hard the install was. Scaffolding is not free remember.

So not the old trout then.

What fish would you put in it?

What make and model is your inverter? Or do you have micro-inverters on the back of each module, or two.

That could be used for a wind turbine, or a solar farm. Or even as a carbon sink, if you like growing trees.

That is because the land down here is pretty dire, grade 3 and below. What I do find odd, is that we grow flowers on a lot of it. Give people some gardens and they may grow their own.

I am a lot more optimistic about it all. There will be huge changes, and a lot of suffering (ranges from a few higher taxes, though less choice on lifestyle, to premature death), but we can, if we choose, and we will have no choice, to easily live on this one planet. Food production is now enough to feed 9 billion people, just got to sort out equitable distribution of it. We know how to, where to, and how much renewable generation we need, so that is just a case of doing it, not quick, but faster than most would have believed just 5 years ago. Personal transport is sorting itself out. I really don't think things are as bad as some people claim. If we 'give' each person 1000 m2 for housing and the associated infrastructure, then that would be 70,000 km2, the UK, as it stands at the moment, has 248,532 km2, so that is 28% of the land area. Just to put that into perspective, it is 17% more than we have already developed.

Kind of. They can, by taking advantage of the light distribution over a year, produce more by keeping the actual power from the modules, rather that the maximum at a certain radiation levels, say 1000 W/m², which is a rare event. It really depends on the efficiency curve if the inverter.

Or allow more rural development to distribute things better. One problem with cities is that you get urban island heat buildup, not a good thing for the residence. Same goes for all the waste and energy generation. These all have to be dealt with.

Like a car engine, they are not at their most efficient at full rated power. Some of the energy is coming out as thermal, rather than electrical, energy. During the odd times the modules produce way over the inverters rating, the maximum power is 'clipped'. Or basically thrown out as thermal energy. Shows the inverter was made by them, rather than someone else. The question from @Home Farm was if he had been supplied a Victron inverter.

Simple, in the UK we could easily release 2% of our total land area to housing. That would double what we currently have. With careful design, just half a percent could house 20 million people. The problem is political will and nothing more.

Do you have a box that says Victron on it. That is the usual giveaway. Why did they swap out a 5 kW inverter for a 6 kW one. Seems a bit odd as it is normal to undersize inverters to improve low light level performance.

What have you actually got there that you know of. So what make and model of inverter, number of modules, total capacity of modules. Can then try and work backwards to see if you got ripped off, which is, I think, what you really want to know.

Hard to calculate without some hard numbers, but I don't think payback is really the best way to look at it. I don't sit in a cold house all year so that I can go on 2 weeks holiday, or worry about the depreciation of my car so I can drive to work, to save some money, to not heat a house so I can go on holiday. You are not much older than me, and we all probably worry about our own mortality from time to time. I think it is normal, only when it starts to cloud judgments that it is a real problem, how I ended up staying in Cornwall I think (not complaining about that though).

500W modules are usually used on large solar farms. They are about 2 metres by 1.3 meters, and weigh around 35 kg.

Common practice for the industry sad to say. Been a few years since I worked in it, but the sales tactics was typical for a double glazing company, which a lot of PV companies where. They relied a lot on people's ignorance, which seems strange to me when they were, at the time, paying £12-£16k for a 4 kWp system.

That is 2 m2 larger than my 2 bedroom house.

A blower, a proper one, would be a useful bit of kit to lend out. How much does one cost second hand? Could join the MVHR kit.

Occasionally, a neighbour, about 100 metres from me, blocks the main sewer. This causes a back up to the 6th house where I am. The smell is very noticeable inside my house. So do you have had neighbours that are causing the problem. If so, report it to the water company, they fine the bend blocking culprits. Failing that, I find it is a hummus supper.

@Home Farm Does your solar array actually have a shading issue?
