Warranties are to be kept to ensure that your solar electric system is covered for repairs if something should go wrong with it during the warranty period. Most solar systems are eligible for some solar rebate under the Gov funded program they must carry a full (But not "limited") 2 year warranty, in addition to any manufacturer warranty on specific components. This warranty will cover all parts and labor, and the cost of removing any not working component, plus also shipping it to the manufacturer or repair shop, this also covers the reinstalling of the component after it is repaired or replaced.
The Solar rebate program's 2 year warranty requirement supercedes any other warranty limitations. Yes even if the manufacturers own warranty on a particular component is less than 2 years, the system vendor must still provide you with a 2 year warranty. Similarly, even if the manufacturer warranty is only a limited warranty that does not include the cost of shipping, removing and reinstalling defective components, the store vendor must cover these costs if the retailer also added the system. Be sure you know who is responsible for honoring the various warranties associated with your system - the dealer, the installer or the shop manufacturer.
The vendor should disclose the warranty responsibility of each party. Know the financial arrangements, such as contractor's bonds, that assure the warranty will be honored. Remember that a warranty does not guarantee that the company will remain in business. Get a clear understanding of whom you should contact if there is a problem. Under some solar rebate programs, vendors must provide documentation that specifies information on system and component warranty coverage and claims procedures.
To avoid any later misunderstandings, be sure to read the warranty carefully and review the terms and conditions with your retailer
Your electric company will most times state you to enter into an interconnection agreement with them. Most times, these agreements set out the minimum insurance requirements that you must keep. If you are looking at buying a solar electric system for your home, the cover you have under your standard homeowner's insurance policy usually meet's the utility's company requirements.
