    Electrek green energy brief: More quotes means better solar pricing, ‘carbon tax’ Cohn, more


    Big installers charge more, some people are ok with that, the solution is to get multiple quotes – Using Residential Solar PV Quote Data to Analyze the Relationship between Installer Pricing and Firm Size – The numbers roughly say;

    Large installer quotes are $0.33/W (about 10%) higher, on average, than non-large installer quotes offered to the same customer (Figure ES-1). The difference falls to $0.21/W after controlling for systematic differences between large and nonlarge installer quotes.

    $0.21/W for install price for installs that cost between $2.75-4.50 is a 4-7% difference in pricing. The report suggests that some people simply want to buy from larger, more well known name brands – and that they will simply pay more. Other within the research group would ave benefited from connecting with local installers. Using tools like EnergySage was shown to lower costs $.30/W – for an average system that’s $2k that could be put toward a battery system.
