Weird to contact you about a fit. Most of the reputable solar panel installers around here had been booked up for months. I know that my parents when they were looking for one, came across a really dodgy company who had a name similar to the company we used but the dodgy company had dreadful reviews (unlike the one we used).
In terms of whether you can save money, it will probably take us about 5 or 6 years to recoup the cost of the panels based on our usage, what we currently pay, what we generate and how much we are being paid for our surplus. My understanding is this is particularly good. My parents aren't generating as much as us and our friends who live 50m away on a different street are generating half what we do. Our set up is directly south facing at top of hill in a bright spot. My parents have two separate sets of panels on different roofs a south facing bungalow and our friends have an East West alignment with panels on both sides. The set up clearly makes a big difference. All of us are NW England.
You might also need to consider whether you want batteries. We decided against as we didn't think we could recoup the cost during the life span of the battery and we don't think the tech is quite there. We were having a wobble over whether we'd made the right choice when there was talk of rolling black outs this winter but I think we've made the right call. At least for now.
I think for us one of the big things is it's given us piece of mind with uncertain energy prices - we don't feel as exposed. We pay for electricity at night but over the course of a year we get most of that back in what we generate. It's a hefty initial investment for medium term security.
For us it's worth it. If we were like our friends who are generating half what we do, Im not so convinced.
The key is to get an assessment on how much you'd generate, compare suppliers (don't just go with the people who knock on your door without checking them out and seeing how they compare to others).
We'd been considering panels for a while but hadn't thought it financially viable until last March (because we missed out on all the early really good deals which we know people on). That really changed with the spike in energy prices which we can't see getting better for at least 2 or 3 years - which was sufficient for us to go for it.
We have been told by a friend in house sales/rentals it can be problematic to sell if you get on a deal where you don't own the panels outright (we do) because you are locked into a contract. If you own outright, it's now being considered as part of the house price which wasn't the case 12 months ago - which highlights that they something people are looking for when buying (so effectively the investment is now locked into our home and we have already technically covered for the cost).
I think the biggest thing is to properly do your homework. There's a million and one options on this so know what you are talking about and don't go into a meeting with a salesman without knowing your stuff first.
