Solar Energy Companies Today

Top Solar Manufacturers and Installers

Solar energy is today the main source of power for almost 1 million U.S. homes that are using solar panels to produce clean electricity instead of relying only on the electricity received from their utility company.

If you plan to use solar energy and reduce your energy bills you need to know what are the major solar energy companies in the world today and how can you benefit from their products and services.

Types of Solar Energy Companies

The solar energy sector involves today several types of solar companies involved in manufacturing or assembling panels, solar installers, financing companies for solar, and wholesale companies for solar panels.

1. Solar Panel Manufacturers

These are solar companies that are manufacturing solar cells and solar panels, some of them being involved in R&D (research and development), while others being only assemblers of solar panels.

2. Solar Installers

These are the solar companies that install solar panels on your rooftop.

We can include here the companies that cover the entire country and also small contractors that are offering their services only locally.

3. Financing Companies for Solar

These companies are helping homeowners to install solar PV system and lower their energy bills.

A solar PV system that can produce enough power to cover most of your energy needs is not cheap, but due to these financial companies, homeowners can get a loan to buy the PV system, can lease the system or can sign power purchase agreements.

4. Wholesale Companies for Solar Panels

From the manufacturer that could be located on the other side of the planet, the solar panels get through a pretty complicated distribution network before being installed on your rooftop.

The solar panel manufacturers are sending the solar panels to wholesale companies, which will then distribute the PV panels to the installation companies, and these are the companies that will put the panels on your rooftop.

The financial companies will be involved if a loan, a solar lease or a power purchase agreement is signed.
