Solar Together experiences?

thriftytracey

I got a quote recently £10,500 for 16 panels and a 2.3 kwh battery, includes installation etc.  I am in the process of getting more quotes which, so far, prove Solar Together aren't any cheaper.  Also, I was put off having to pay £150 in advance for a survey, although they say it is refundable if you don't proceed.  I know nothing about solar, since then I realise that 2.3 kwh isn't great capacity.
