With so many solar panels on the market, what’s the best choice for your home? Do you decide based on performance, warranty, or cost? — or all of the above?
The experts at ReVision Energy aim to make the decision easy for you. We carry a range of solar panel options for your home (as well as associated inverter technology) to meet your solar electricity goals.
We’ve been installing solar electric (also, photovoltaic, or PV) arrays in Maine, New Hampshire, and Massachusetts since the early 2000s, when solar panel sizes were very modest and systems were only suited for remote locations where grid connections were not possible. Since solar panels have gotten much more efficient – and have dropped in cost by over 75% – you can power your entire home with solar panels.
Long story short, a solar panel works by generating electricity when particles of sunlight, or photons, knock electrons free from atoms, setting them in motion. This flow of electrons is electricity, and solar panels are designed to capture this flow, turning it into a usable electric current. This process is called the photovoltaic effect and is the foundational chemical and physical process behind the vast majority of solar technology.
The photovoltaic process works through the following simplified steps:
While solar technology continues to improve, the core components have not changed much, and, while the finer points are quite detailed, the basic concept is simple. Grid-tied solar arrays need solar panels and one or more inverters.
This stuff is important! We think our customers should be able to learn all about the technology we're installing on their homes. Solar energy products continue to improve as we innovate and refine the technology. At ReVision we can guarantee quality and continued service for our customers, no matter what kind of solar panels we're installing for you.
Nearly all solar panels sold in the United States are crystalline silicon modules (cSi), a form of solar panel that consists of rigid silicon wafers (which may be ‘poly’ or ‘mono’ crystalline – referring to the process by which they are manufactured and grade of silicon from which they are cut) housed in a weatherproof enclosure (tempered glass and aluminum).
All electronics are soldered to a backing board and have positive and negative electrical outputs that allow the solar panel to be connected to others in a string. This is the same basic design of solar collector that has been used since the 1970s.
We frequently hear about upcoming future generations of PV (everything from thin film to Elon Musk’s solar tiles) however we strongly feel that cSi solar panels remain the right choice for the New England market. Solar modules in our region need to endure decades of abuse from wind, snow, and hail, and we know that cSi solar panels can do that. With over 100,000 solar panels in the field, we can say that roof leaks and module failures are nearly unheard of.
Lest you think that a 30+ year old technology is stale and dusty, recall that loudspeaker technology is essentially the same as it’s been since the 1920s!
The advancements in cSi technology have mainly focused on reducing the cost of module production and improvements in performance. For example, in 2009 a typical 3′ x 5′ collector would be rated to produce around 230 watts of electricity. These days, the same size panel may produce more than 400 watts!
Residential solar installations across the globe utilize 66 cell solar panels whereas 72 cell panels are more common in large commercial ground mounted systems. We have experience with both panel types and have found that smaller panels are superior for rooftop solar installations in our region for these important reasons:
The standard size solar panel is the clear winner for our residential systems to stand up to our winters and keep our installers safe, without sacrificing solar production.
Absolutely! Nearly all reputable manufacturers will offer a 25-year power production warranty (guaranteeing output of 80% over 25 years, though people have found collectors from the 1970s that still produce 100% of their rated power today). The better manufacturers will also offer at least a 10-year aesthetic warranty, which covers defects in the look of the collector that do not affect performance. With REC panels, we have a ProTrust Installer Rating, which gives us one of the strongest equipment warranties in the business – a 25-year product, labor, and performance warranty.
Know that any proposal received from ReVision Energy includes modules that any employee-owner of our company would be proud to install on their own roof.
The best solar panels for you will depend on where you live, how much power your home needs, and other factors. Our skilled solar design specialists will help you figure out those details and find the best solar option for you and your home.
Currently, our most common solar panel choices are Q CELLS and REC. We have developed long-standing, mutually-beneficial relationships with both companies, whose quality products and exceptional customer service make them stand out in the industry.
Our high-efficiency solar panel option comes from Q CELLS, a German engineered solar technology innovator with assembly plants right here in America. Their high-efficiency DUO BLK ML-G10 module is the first 400W panel offered for residential solar customers, and ReVision is thrilled to bring this module into our lineup.
There are many benefits to using high-efficiency solar panels over standard-efficiency ones. Roof space is at a premium on every solar project–there is only so much physical space we can work with! A solar array with high-efficiency panels allows us to set up a system that will generate more power per square foot than a system using standard-efficiency panels. A high-efficiency module like the Q CELLS DUO BLK will produce more electricity than a standard panel on the same roof. Furthermore, a high-efficiency panel has the same reliability, durability, and long-lived warranty as its standard-efficiency counterpart, and are our go-to when trying to maximize the electricity we can generate on a roof that may have limited exposure or other shortcomings.
Q CELLS is an award-winning solar manufacturer with record-breaking design and engineering teams that are constantly developing new, high-efficiency solar tech. With R&D locations across the globe, they are committed to making cutting edge solar energy options affordable and sustainable to homeowners and businesses in the USA. Q CELLS’s module assembly plant, located in Dalton, Georgia, is the largest in the Western Hemisphere, and marks the significant growth of the US solar industry and our collective transition to clean, solar energy.
REC Group offers a variety of solar panels, each as powerful and durable as they are sleek and stylish. A long-time forerunner in the solar energy industry, REC combines rigorous testing and advanced technology to produce a line of high-quality residential solar panels that we’ve come to love. Plus, thanks to our ProTrust Installer rating, every REC solar panel we install comes with their 25-year ProTrust Warranty.
REC’s resilient solar panels are the perfect option for homes in New England, where harsh weather and frequent outages plague us all winter long. They are tested specifically for strong wind, snow, hail, and other unpredictable variables, and are leaders in avoiding power outages, making them our best option for households in the Northeast. We’ve partnered with REC to purchase a large volume of their solar panels for our commercial solar projects. Because of this, we have secured significant volume discount pricing which we can extend to our residential customers.
REC is a vertically integrated manufacturer, meaning they are less vulnerable to supply chain disruption than some manufacturers. This also means they have excellent quality control and consistency. We’re grateful that, like us, REC is committed to solving environmental problems by making home solar products more sustainable and more cost efficient than ever.
Our relationships with REC and Q CELLS, two innovative companies committed to quality and performance, enable us to offer our customers the best prices, regardless of which solar panels you end up getting. In our journey as a B-Corp, we’ve learned that doing the right thing for people and the planet often ends up being a good financial decision, too. Taking the time to foster supportive, mutually beneficial partnerships with our solar panel providers means more opportunity for us, and lower prices for you.
One of the most common (and most challenging) questions we get is — what do solar panels cost? To answer this, it’s important not to look at the cost of a solar installation solely at the cost of the solar panels themselves.
So much more goes into it – design and engineering on the front-end, permitting/rebates and interconnection paperwork, and a team that is able to efficiently and safely install the solar panels on your roof (or yard) and connect it with a solar inverter which may be in your basement, garage, or even mounted outside. Pricing is affected by the site-specific details of your home; such as how many stories tall your home is, how complex the electrical work will be, and other site specifics.
ReVision offers the most competitive pricing we can possibly offer, while also running a company of the highest caliber. Some things that differentiate us from the competition:
