We have trained over 1,000 solar contractors that are starting solar companies or working in some of the largest solar integrators on the east coast.

Module selection is a huge part of the process when building a company and completing projects and we want to understand what your companies are purchasing for modules and why.

We will be creating a huge database of resources among many industries (solar pv, geothermal, solar thermal, and energy efficiency) and through many categories of equipment (modules, racking, heatpumps, grout, collectors, etc) for all of the installers, engineers and sales people working in these industries.

We want this information to be created by feedback from the community of installers using the product not the distributors or manufacturers.┬áVoting will only be allowed by installers, no distributors or manufacturers can vote. The reasoning is simple, we want to make the list useful for contractors and not a sales presentation. We’ll maintain quality by requiring a valid company name, website, and email address.

The results will be published and made available to everyone for free.

NOTE: We will not publish your name, company or any personal information. We will only publish information about solar modules.

Here’s how the survey works:

  1. Vote for one module, your favorite.
  2. Select the reasons why from a survey
  3. Provide an anecdote as to why you selected the specific module
  4. HeatSpring will compile all data and make it available to the public
