If you buy everything you need for a grid-tied solar set up, can you install it yourself or is it required that a professional installs it?
For safety purposes and liability, I do suggest that you should hire a professional solar panel installer. The solar panels has a lot of engineered like work, So better hire someone who has a fully aware for this work.
By an utility approved qualified individual. The utilities really hate it if their maintenance people working on the power lines gets electrocuted because some solar powered inverter didn't shut off when they shut the line off.
Solar panels have to be installed by a professional in order to get the government rebates. Also the systems must meet state and local electrical codes. Most modern inverters will not turn on unless there is live power from the MAINS, so a ultility company is NOT required for any installation anywhere. There are plenty of electrical contractors and speciality solar contractors out there to help you to make sure that the system is properly designed with the correct components, properly installed, and legally certified. Also many states require a permit that may have a large fee before any installation and may not allow the homeowner, especially for city homes, so it is best to check first. You might be able to get away with it if you live in the country, but consider the safety as well. See if you can work with your contractor to get the materials that you both agree upon as well. They can help guide you based upon their experience. Also shop around for pricing as the panels are now going below $ per watt !
