Is Solar Worth It? Part 1

- We have, in the past, looked into getting solar panels on our house but were told we couldn't get enough panels on our roof as we would need 9 or 10 panels to make it worthwhile. Inspired by an advert for a cheap 4 panel setup I have decided to look into whether it is actually worth us getting just a few panels.
Looking deeper into solar panels I started to question whether solar panels are worth having at all! In this video I investigate the economics of having just solar panels. In the next one I'll see if it is worth adding a battery to the system.

Hi, I had Solar installed back in 2022 (6KW), just before the energy prices exploded, and you do export in winter, because as you said, when your not at home, its just pumped out to the grid, I then had a battery installed 6 months later, and the self consumption rate (winter) went from 60% to 98%, as the battery is charged during the day, and even in winter, on a bad day, will still charge it to about 50%. One thing to consider when working out payback, is also treat your self as an energy supplier to yourself, so the electric you use, calculate how much that would cost, and include vat too, I have worked out my break even point at about 5.5 years for my system, not the 10+ years you have suggested. my solar array is a SE/NW orientation system, both sides of roof is covered.
I'm with Octopus and they are currently paying 15p/KWh exported. From the last 2 years data I have, the payback for the 4.2Kwh peek system I have looks to be in the region of about 5.5 to 6.5 years.
I currently do not have a battery, so I sell as much over production as possible back to Octopus, and then use any heavy appliances during off-peak (E7) as we are currently paying less for off-peak (13.31p/KWh inc. VAT) than Octopus pays us to export (15p/KWh).
And.. You defiantly export in winter, between November 22 and April last year I got paid almost £65 for electricity I exported. Plus, (as already pointed out) you also have to take into consideration the cost (including the vat) saving of your self-consumption as if you had purchased it.
The reason we would get such a poor rate for exporting solar energy to the grid is that we have an EV tariff which allows us to charge our car for 7.5p per kWh during the night. The down side of this is that we would only get 8p per kWh for exported energy.
As for exporting energy in the winter - maybe I got my calculations wrong. I will check them again when I come to do part 2.
@@TripplikitElectronics No problem, I realized after I posted you wouldn't get 15p export due to being on the Go tariff and meant to edit my post but forgot!!
you explain it like shares on the stockmarket and companys go also out of business
and then youchart is useless.
are they wort it yes with the taxpayers money , from your own money and making it compleet
that it runs your home complete no it is useless to dat it can be good but tomorow
it is a waste of money nothing is forever.
I don't think the taxpayer is offering any money to install Solar panels in my part of the world.
