I'm due to have a new roof in the next month or so, and the roofer has told me
he can install some solar panels 'while he's up there'. I'd imagine there'd be
an installation cost, but it'd likely be considerably less than a heat pump
installer has quoted (about £14,000 including a 6kW battery).

My question is - would it be worth me buying the 8 panels (about £1000
https://midsummerwholesale.co.uk/buy/longi-solar/longi-lr554hih-410) and
getting the connection sorted out later?

Part of my reason for asking is I'd much prefer a roofer installing the panels

Solar pv now makes sense if you can get it all done cheaply, and have a way to use the power. Can you?

Well, it might be reasonably cheap - I'm thinking <£5000 for 8 reasonably
located panels and storage. Based very loosely on
http://wiki.diyfaq.org.uk/index.php/Solar_PV_example:_single_garage - but
unless it's not obvious, I'm fairly clueless about the whole thing.

The financial return isn't a huge consideration if I can get it installed for
that sort of figure.

I could certainly use the power (when less is available, of course) in the
winter. But not so much in the summer. So I'd need to look into a FiT for a
decent financial return. An electric car is on my horizon, but not for a
while.

I suggest that it depends on the quality of the panels and the company
doing the work. the company I used had good people working on the roof.

Also, if you had a complete installation done you wouldn't pay VAT, butif
your roofing man just puts up panels then you could end up paying VAT on
them. His price for panels seems quite cheap. I had a system installed 4
months ago, and 8 panels would have worked out at £6700. Mind you that
price probably includes installation and wiring.

Just looking at the spec for my panels, they are wired up from the back, so
they'd need to be taken off to wire them up.

You would get more return right now installing an oil boiler and oil
tank and filling it up.

It used to be that the inverter cost quite a bit, plus the gubbins to
safely feed into the grid.

This can significantly increase the installation cost.

I would but have you an electrician to connect the lot up? The DNO must
be notified prior to connection to the grid but they will require a
qualified electrician (not necessarily MCS certified) and they are bound
to allow you 3.68kW connected. More than that and you have to get
agreement in advance of connection but it is worth having more than 4kW
of panels if they can fit and faces anywhere from East to Wet facing.

Unless you use less than 3MWh of electricity a year that battery is
probably too small. Last March we fitted 6kW PV, a 5kW inverter, a car
charger and 10kWh of storage to my daughter's roof, she has not needed
to buy electricity other than off peak at 11p/kWh since and then only
November to now. Since then panel prices have dropped.

As scaffolding is a fair chunk of the installation cost it will probably
be worth absorbing the VAT on the panels but your roofer could do this
bit as a sub contract to the electrician then the electrician would not
charge VAT on the whole installation.

If the DNO is happy with the installation then at least one energy
company will pay you for the excess power you export, the rate is high
currently (8-15p/kWh) but I don't think that will last as wholesale
electricity prices fall over the coming months.

In theory, they are just mounted on brackets that go through to the main
roof construction underneath. I'd have thought if they were that bad there
would have been a lot of complaints by now.

You need to decide on your end use for the power.
If you want fits (equivalent), you'll need a whole approved system, which this won't fit.
If you're heating hot water, 2 panels is enough for most folk.
If you're charging a car, it might make sense if you're home most of the day & don't get storage & can use the power the panels produce. But the popularity of EVs is likely to evaporate due to people realising how problematic they are.

2 panels feeding a HW cylinder is an easy win if the price is right, 5k is way too much for that.

If being done as part of a new roof, consider in-roof panels where the
panels are the roof, rather than mounting them on top of the roof. That
will save buying the tiles to go under them, bird-proofing around them,
cutting brackets through the tiles, etc.

My estimate based on the DIY wiki page. Panels seem to have gone down in price
recently - but supply looks to be very patchy.

I've thrown the whole thing over to the roofer - so I'll see what he says.

Good to know, thanks. How incidentally does the wire(s) find its way into the
roof void?

It's not just economic return. It's also about reducing waste and consumption,
and comfort. Personally, I wouldn't be relaxed using an oil burner at full
tilt just to save a few quid.

At this stage, I'm thinking of insulating as much as possible (my home is
already pretty good for a 1920s semi), abandoning the ASHP and factoring in a
new gas boiler in the next 5 years, and solar as a reasonable cost/return
option while I'm having the roof done (and I can afford it).

Thanks - I'll tot all that up as the idea develops. Right now looking at 8
panels, so below the 3.68kW

Indeed. But this proliferation of installers is quite recent. Maybe earlier
installs were done by more able contractors?

Not sure TBH.

Apart from maybe Octopus, export tariffs require an MCS certified
installation evidenced with an MCS certificate.
Some MCS certified installers may refuse to work on a part install
performed by someone else.

The cowboys have moved from double glazing, conservatories and
insulation to solar panels and heat pumps.

That may limit repair options if a panel or two fails.

It doesn't. My battery and inverter are mounted on a outside wall. Wiring

110kg - not something easy to carry into a loft. The inverter is 'only'
32kg!
