Your Guide to Finding Great Sustainable Energy 

After hearing a persistent knock on your door, you peer out your window and see another door-to-door solar salesperson.

You're interested in solar, but the companies' offers are starting to blur together. Choosing a solar company is a serious decision, so this top four list will help you narrow down your options of the best solar companies in america.

Why Solar?

Solar energy has become increasingly popular, so it's important for consumers to research and evaluate solar companies.This list takes into account the following factors:

●       Price per watt

●       Transparency

●       Equipment

●       Warranties

Some solar options may appear to be a steal, but without considering these important factors, you may find yourself paying more than necessary.

How the Ranking was Determined

Price Per Watt

Anyone who has spent time researching solar panels knows that it can be difficult to find and compare prices. What needs to be considered? What is a good price?

Price per watt (PPW) is a system's cost divided by its wattage. This is an important metric for comparing solar because you can analyze the value of systems built with different equipment.

With several of the companies listed, it was difficult and sometimes even impossible to find an average PPW. This is a telltale sign that a company's salespeople determine their prices on a case-by-case basis.


A company's level of transparency contributed to each ranking since vague pricing information complicates the process and unsettles potential customers.

Inevitably, price variability occurs in the solar industry because of different locations' permit fees and labor costs. However, many solar companies offer the same products and services for inflated prices, based not on equipment and labor costs, but on the related cost per kWhr of the local utility provider.

Choosing solar energy is an investment, and you deserve to feel comfortable and well-informed throughout the process.

Inverters Offered

Whether you're new to solar or an energy sage, it is important to compare products. Inverters, for example, are essential to your system.

Inverters convert the sunlight energy into usable energy for a home. The two most common types are string and microinverters.

A string inverter hooks up all panels to a single point of control, so if there is a single problem with one of the system's parts, it will affect the performance of the whole system.

String inverters typically only come with 10-12 year warranties which can leave buyers out of luck less than halfway through their panels' warranty.

Microinverters, on the other hand, are generally preferred. Many find microinverters worth their higher price because they last longer and are more efficient.


With today's great panel options, you shouldn't settle for anything less than 25-year product and performance warranties on your panels. Solid warranties help ensure that you'll receive a proper return on your solar investment 10 year workmanship .
