When you are considering going solar is important to be focused on kilowatt-hours, monthly payments, or total savings. Also, it’s important to know the type of solar panel that you are installing. Selecting the best solar panel and comparing it from hundreds of different models can be challenging. Solar panels are basically the same in terms of how they operate and it’s hard to know the difference between a good and a low-quality product. It takes years to see how they will perform and before any potential quality issues will become evident. You don’t want to end up getting a panel that is economic but won’t do the work that is supposed to do. That’s why it is important to get solar panels with a good warranty. 

Panasonic Logo

Panasonic is one of the world’s largest manufacturers and a popular choice for homeowners. It’s the best option if you are looking for a trustworthy company that has been in the market for a long time. You want to choose a company that is able to support you thought the whole life of the solar panels. Panasonic’s new model, the HIT panel, guarantees that will provide a 90.76% power output after 25 years. That’s 13% more power compared to what is offered by a traditional solar panel warranty. Panasonic panels are highly rated and reviewed in the USA.

The models that we offer from Panasonics are VBHN 330 SA17; VBHN 340 SA17.

Q Cells Logo

Hanwha in 2012 bought the German solar manufacturer Q Cell. They are the world’s largest and most recognized photovoltaic manufacturers for its high-performance, high-quality solar cells. They offer a great range of photovoltaic products, applications, and other solutions. The panels are a good option for many homeowners without any premium markup. Their 340 Watt all-black panel is their most famous panel. In 2019 the company built a facility in Atlanta, Georgia to manufacture solar panels for the US market. 

The models that we offer from Hanwha Q Cells are Q.PEAK DUO BLK-G5 320; Q.PEAK DUO BLK-G6 330; Q.PEAK DUO BLK-G6 340.

Solar Model: Panasonic 340 Watt HIT

The HIT technology has a great performance for the New England climate. The advantages of HIT technology is that heterojunction technology minimizes electron loss. Panasonic panels have a higher performance at high temperatures. This is the best solar panel if you live in a place where the sun is available all year round. Also, it has dual-sided cells that multiply the energy output, and it has smart water drainage for peak power. Lastly, the company has strict quality testing standards for long-life performance. That’s why these solar panels are a great option. The panel has a higher efficiency rating higher than Q Cells. Panasonic has a rate of 90% year 25 performance guarantee.

Solar Model: 340 Watt-all-black Panel

Peak-Duo technology separates the modules into six sections. This is very unique in the industry, as most solar panels have three diodes/sections. Before diodes, a small portion of shading from a tree or snow could knock out an entire solar panel. In recent years, panels have three diodes, meaning only a third of the panel would lose power. The panel’s design is all-black, with its silver bus bar lines that are readily apparent. The 340-watt panels have a good power output. Q Cells are an economic option compared to Panasonics.
