Why you should ask these questions? All of this information should be included in both your bid and on the contract you sign. Check these details carefully, then compare to other bids you obtain. (Get at least 3 bids, all in writing.) Be wary of any really low bids. If the contractor can’t supply the information, ask why not. After checking any contract to be sure this information is included, have a contract expert or lawyer review the contract before signing it.
- Is this bid an estimate or a fixed price? What is the process you will follow if you find unexpected problems with this installation and want to charge extra to fix the problems?
- Does the bid include the total cost of the project, including components, materials and labor?
- Does the bid include a breakdown of each of the components (make and model number, size/kWh per year, as well as price of each) so I can see what each portion will cost?
- Does the bid include details about permits?
- Does the bid include the time frame for beginning and ending the installation?
- Does the bid include warranty information, as well as how to place a claim?
- Does the bid include expected operation and maintenance costs; projected monthly, annual and lifetime costs and savings; and projected energy production?
- Does the bid include payment options, as well as financing details?
- Does the bid include details about who will file paperwork for tax credits, rebates and other incentives?
- What documentation will I receive when the project is done? (This may include lien releases and other contract-related paperwork, as well as warranties, operating manuals and more.)
