AES will not provide a quote thru EnergySage. You need to work with them directly.
All Energy Solar is a good vendor. The people we dealt with were all good, all professional and AES has a strong reputation with the inspectors and others that work with them. We got a quality system (15 panels, 5kw) that meets our needs and had a relatively smooth process. Be aware the process with design, approvals, etc. may easily take four months or more.
The three solar vendors we talked to were all very professional, knowledgeable and enthusiastic about the field. Not your usual sales experience.
In spite of the huge cost reductions in solar in the last 10 years, realize that those savings do not all come down to us consumers. Government subsidies have been reduced. And vendors need to make money. We paid $3.85 per watt for our installation, which is above the national median price for residential solar ($3.5 in 2018), but not wildly so. When I asked for an estimate for another 10 panels, the response was the cost would go up proportionately. Without any gains recognized from the relatively fixed costs of project management, approvals, engineering, site visits, purchasing, etc. One may wonder whether the price is partly based on providing a 10-year payback for the homeowner, but no better.
We did identify to the sales rep that we wanted to leave room on the roof for future expansion, more panels. We reiterated that to the site engineer when they came out, news to him. Once when we got our engineering drawings, they likewise did not reflect our desired, more compact layout which would allow for the addition of more panels. So, if you have particular requirements, make sure to follow those through the entire process.
