I saw that this website (https://solarbright.energy) has very good deals, but I suspect they are a scam.
Why:
They have a UK phone number that nobody answers, I got a very defensive response when I asked too many questions, seems "too good to be true", says they support Paypal, but checkout system doesn't forward to Paypal, no social media, no verified TrusPilot company info, etc
But maybe I am wrong?
Would advise against. The domain has only existed for 203 days according to whois (created 5/19/2023), and is registered in California USA even though the site claims to be based in Taiwan while their prices seem to be in Euro, and BitDefender records multiple threats when the site is open, including mismatched security certificates from some totally different domain that doesn't have a website but that's registered in Reykjavik. That's a lot of stuff not adding up.
Suggest you stick to authorised dealers. Justin has done an excellent analysis. Two UK ones I've used are energy monkey and 12 volt planet. There are many others. See here:
