By 00

1. SolarCity

energy grid

All about the energy savings, SolarCity has a 5% higher than average efficiency percentage on their slim panels. Their best features are in installation and monitoring, with a real-time app to follow your production and savings, as well as your own personalized energy consultant who works with you from initial questions to final inspection. Although you can’t move the panels if you move home, they guarantee savings for families who have an electricity bill of $100+ per month.

2. Wholesale Solar

wholesale products

Wholesale Solar Wholesale Solar offers bulk discounts and cost pricing for PV solar panels as well as any individual components you need for your energy system. A 100% family-owned company, they often have flash sales, and are one of the cheapest ways to buy your solar panels online. However, they do not come with installation included, which makes them less suitable for residential homes and more for larger businesses. The brand comparison table on the website makes it really easy to make a smart choice for your company.

3. Sunpower

black panels

Sunpower Sunpower has an international presence in the solar energy market, and offers its unique all black cell panels, which are far easier on the eye than the silver panels you may be used to seeing. This makes them a more aesthetically friendly choice for rooftops. They have 30 years of experience developing their own solar panel structure, and have achieved a hard to beat 21.5% level of efficiency. You can lease, loan or purchase your system, and although the installation is outsourced, they only employ Sunpower certified companies.

4. Sunrun

custom design

Sunrun Sunrun sells government funded and approved products, and is the largest energy provider for residential solar systems. They have a unique BrightPath system which allows your installation to be custom designed for your home, and lets you pay for your choice in the most affordable and hassle-free way for your financial situation. They were even the pioneers in the PPA agreement which allows leasing of solar panels. Transparent from the outset, your engineers will create a savings forecast for you based on your home, and then refund the difference if the predictions fall short.

5. SolarWorld

solar guarantee

SolarWorld SolarWorld stands out because of its 25-year performance guarantee. They promise that your system will reduce in efficiency by a maximum of 0.7% every year. They are tested to an extremely high standard and are made of the highest quality monocrystalline materials with almost 22% efficiency-industry leading standards. The panels are also made to be weather and climate resistant which makes them great for areas of the States with extreme temperatures. They outsource installation and have tricky customer service options, which makes them best for commercial businesses rather than residential needs.

6. Baker Electric Solar

environmental benefits

Baker Electric Solar The environmental benefits of solar are clearly of utmost importance for Baker Electric Solar.

Based in San Diego which is one of 25 Solar Cities in the USA, there are plenty of incentives to make going solar affordable and work for your home.

7. Standard Solar


Standard Solar Standard Solar is great for businesses. They have a slightly longer timeline for your project as they are used to working on large scale commercial installations. They are flexible on the location of your panels, for example roof ground or carport and are known for their innovative and flexible designs when space is an issue. They employ only NABCEP certified engineers, and take care of everything from initial quote and permitting to monitoring- a true end-to-end service.

8. Milestone Solar

installation panels

Milestone Solar Customer service is everything for Bill Anderson from Milestone Solar in Maryland. The company actively looks to take on fewer clients from their small four state covered area, and create a better customer experience for them instead. The CEO might even complete your installation himself! Focused on customer satisfaction, you will receive a free on-site inspection, in-depth monitoring after installation and a multi-certified technician and contractor. For those who want bespoke rather than speedy service.

9. Sullivan Solar
