EPC stands for Engineering, Procurement and Construction. It means EPC companies have the necessary licenses, experience, financial and logistic capabilities to deliver a project from start to finish. They have strong relationships with the following entities to deliver a complete project:

  1. Solar Financing Companies to offer financing options (solar loans, solar lease and solar PPA).
  2. Solar parts distributors to deliver solar panels, solar inverters, wire, cable, breaker boxes, etc.
  3. Their bank to give them credit lines to deliver the projects until they get paid from the customer (in cash purchases) or from the financing company (in case of solar financing).

Moreover, they have the following teams in-house or outsourced to deliver your solar installation:

  1. Site Audit/Survey team to conduct a survey to measure your sqft of suitable roof space for solar panels, measure your sun exposure, check your roof age, check compatibility of your Main Electric Panel with the solar power system installation. This can be done by an in-house team, but a lot of EPC Solar Companies outsource this to independent contractors.
  2. Design team to draw an accurate solar site layout of your house showing all the panels on the roof. This can be done by an in-house team, but a lot of EPC Solar Companies outsource this to independent contractors.
  3. Engineering team to sign off the solar site layout for permit process. This can be done by an in-house team, but a lot of EPC Solar Companies outsource this to independent contractors.
  4. Procurement team to maintain relationships with the solar distributors and place orders.
  5. Solar installation team to install your solar power system in compliance with the approved site layout. This can be done by an in-house team, but a lot of EPC Solar Companies outsource this to independent contractors. These independent contractors are called Solar Subcontractors.

In addition to the above items, they must have enough experience to deliver the projects.

Now, let’s find out who is a solar subcontractor.

A solar subcontractor is an individual or a legal entity who is licensed to install solar power systems. They must have the required experience and the necessary licenses (C10 or C46) to install the systems. Usually, they don’t have the financial capability to deliver a project from start to finish, so the only take care of one part of the whole process, which is installing the solar power system. They are usually small local solar installers.

If you are looking for a solar installer, you should get advice from an independent energy advisor who is experienced, licensed and unbiased towards installers. This energy advisor will be your advocate throughout the installation as your representative.
