Compare your costs for a traditional project to a solar alternative.


In the past, solar lighting was practical for remote locations with no possibility of a grid connection. But now? Today’s solar lighting is more viable for more projects than ever before, even when a grid connection is close by.

How would your costs measure up? Consider your specific project location: what does it cost to add on-grid power? Use our cost calculator below to compare traditional grid costs to solar costs and determine which is the best option.



  1. Use our Build & Price tool to get an estimate for solar lighting for your application.
  2. From the Build & Price tool, click the link “Bring my Build & Price Estimate to the Cost Comparison Worksheet” to return to this page. The numbers will automatically fill in Part 2 of the chart below.
  3. Use your own existing data and knowledge to fill in the numbers for Part 1.


All numbers in hand? Fill them in now to see your project cost comparison.
