Why Is Solar Pricing So Elusive?

How much is this going to cost me? 
Can someone at least give me a ballpark price range?
Why can’t I find a published price for a solar system?  

These are some of the most frequently-asked questions by individuals researching solar. Sometimes, the perceived lack of transparency in pricing is used as a knock against the solar industry.  Is it really so hard to reveal the price of a system? 

Unlike purchasing a one-size fits all consumer product, even something like a car, the customization required for each solar system makes it difficult to price without performing a custom estimate. Any solar investor should receive an “all-in” price before they begin a job. This article outlines some important questions to ask and reasons why prices are best tailored to each individual situation.

Rough estimate pricing can almost always be provided with a cursory glance at a site, but both the investor and the solar company should demand precise and fixed pricing in advance.  Some variables that require job-specific investigation before pricing are:

  1. Risk profile of the site:
    1. Does the roof have an extreme pitch?  Is it of an age that requires additional work prior to solar installation?  Does roof height require equipment such as lifts?
    2. Where can the system tie into the power of the home and does this electrical service require additional work prior to solar installation?
  2. Local regulations:
    1. Certain utilities and municipalities have very specific solar processes which can add time and cost to an overall job.  Some examples include:
      1. Electrical grounding requirements
      2. Wind rating requirements
      3. Permit processing fees and timelines
      4. HOA regulations
  3. Warranty and service options:
    1. Does the owner desire power production tracking?
    2. How long of a warranty does the owner prefer for peace of mind?
    3. Does the owner desire pro-active service and site visits?

Most solar prices are offered in a per kW format, which adds up to a lump sum contract.  Those investing in a solar system for their home or business are usually best protected by a lump sum (stipulated sum) contract for services and goods.
