A solar power system is one of the biggest investments a homeowner will ever make, so make sure everything is properly installed and designed to last.
Components vary widely in electrical performance, form factor, and weight, but most modules come with a 20-25 year warranty, making solar power a long-term investment, depending on a solid foundation for high-quality installation.
The first inclination in looking for a plumber should either choose the cheapest option or believe that the one with the best price is the best and go for it. A better option is probably somewhere in the middle.
A good solar company in Los Angeles will manage all the power lines, which means they will source all the spare parts for you and manage everything from start to finish. This usually means wholesale prices and materials are provided for some savings.

The danger with the cheapest installers is that they offer a cheaper service with lesser components. Keep in mind that while solar panels can last 25-50 years because important components in energy converters are not durable.
So make sure they are of the highest quality, but the best way to ensure your entire system will work for decades.
Finding the right plumber is similar to finding a contractor or general contractor to furnish your home.
