What To Know About Going Solar

From charging your phone to heating your home, energy powers your life. Unfortunately, not every energy resource is sustainable. Currently, many people rely on fossil fuels for most of their energy needs. Fossil fuels are finite resources—such as coal, oil, and natural gas—found in the earth and release excess greenhouse gases into the atmosphere – the root of climate change.  

Solar energy, on the other hand, is cleaner and limitless. If you are interested in going green, solar panels may be a great addition to your home. Here are the basics you need to know.

How do solar panels work? 

As you drive through your town, you may see solar panels on the roof of someone’s home. These solar panels, or photovoltaic cells, rely on sunlight to create a microscopic reaction that separates electrons from the atom. This separation results in an electrical current that we can harness and use. Even when the sun isn’t shining, power is generated by an electric grid connected to the module.

What to consider before getting solar panels 

There are a couple of factors you need to consider before installing any solar panels on your home, including location and orientation to the sun. Solar panels should be placed in a location with plenty of direct sunlight and free of any trees or buildings that could block the sun’s rays. For houses in the Northern Hemisphere, it is optimal for solar panels to face south.  

Once you confirm that your home is suitable for solar panels, you must decide what type and number of panels to install. A solar photovoltaic (PV) module can be installed on your roof or mounted on the ground.

Buying versus leasing solar panels 

While both buying and renting solar panels are cost-effective green solutions to powering your home, there are different advantages to both options. When you buy solar panels, they can increase your home’s value and save you more in your monthly energy costs. On the other hand, upfront costs for solar panels are much less when leasing, and you are not in charge of future maintenance.  

No matter what you decide, there are several statewide and third-party programs to help you finance solar panel installation. If you choose to use a third-party program, there are typically two types of agreements. The first is a lease that allows you to only pay for the solar system rather than the electricity generated. The second option is a power purchase agreement (PPA) in which the provider installs the PV array and then sells the electricity generated back to you at a rate that is usually lower than the local utility price. 

If leasing or buying isn’t feasible for you, a community solar program where you receive energy from a shared solar system, may be a perfect solution.

Solar at Mass Audubon

Here at Mass Audubon, we strongly support responsibly-sited solar power, and improved access to it, as highlighted in our Action Agenda goals. Through careful site selection and consideration, 20 Mass Audubon wildlife sanctuaries are powered in part or in full by solar PV arrays. Our teams meticulously choose solar installation sites to minimize the loss and fragmentation of existing ecosystems and support resilient landscapes, so our first choice is to always install solar panels on an available roof. 

Mass Audubon’s largest array, with 119 PV roof panels, powers the Environmental Learning Center (ELC) at Drumlin Farm in Lincoln, and even has excess power for nearby buildings to use. In addition to the ELC, the Nature Center, Farm Life Center, and Green Barn are all equipped and powered in part by separate solar arrays.  

Unlike the panels at Drumlin Farm that are fixed in one direction, the PV array at the Arcadia Wildlife Sanctuary in Easthampton tilts and rotates to follow the sun. Throughout the day, the panel adjusts to track the sun’s location and generates as much solar energy as possible. Compared to a fixed array, adjustable arrays can harness 45% more power. 

In April of 2022, the Boston Nature Center in Mattapan announced it’s accomplishment of reaching a net-zero energy status, or becoming carbon neutral, through the installation of solar panels on the George Robert White Environmental Conservation Center, and a nearby ground-mounted array. By becoming carbon-neutral, the Boston Nature Center is eliminating the emission of more than 136,000 pounds of heat-trapping carbon dioxide annually.

Green Your Transportation

In recent years, the transportation sector has surpassed power plants as the largest source of carbon dioxide emissions in the US. The low cost of fuel, American’s desire for bigger vehicles, and continued sprawling development that requires more individuals rely on automobiles to move around has driven a steady uptick in vehicle emissions.

This makes the transition to an electric or hybrid vehicle one of the more effective things you can do to reduce your carbon footprint. If you’re among the 83% of Americans who drive regularly, it’s now easier than ever to switch to electric and hybrid vehicles that emit roughly a quarter as much CO2 as gasoline powered vehicles.

Why make the change?

Unlike traditional vehicles, electric vehicles do not release any exhaust emissions when driven. This means that they not only reduce greenhouse gases in the atmosphere, they also eliminate dangerous air pollution that causes smog and other health and ecological risks.

Even better, drivers can cut their emissions down to zero by charging electric or hybrid vehicles through renewable energy such as solar, wind, or hydropower. That’s why Mass Audubon now provides electric vehicle charging stations at many of our sanctuaries across the state, all powered by renewable sources. It’s also why we support An Act to Secure a Clean Energy Future, which sets zero-emissions standards for state-owned or leased vehicles.

Beyond helping save the planet, a greener vehicle can save your wallet as well. On average in the US, the cost of fueling your car with electricity is less than half the cost of fueling your car with gasoline. (You can even charge your car for free at the Habitat Education Center & Wildlife Sanctuary or Wachusett Meadow Wildlife Sanctuary.)

Electric vehicles are also more reliable and cheaper to maintain than traditional vehicles. If that’s not reason enough, when you purchase a new electric vehicle you can receive up to a $7,500 tax credit from the federal government, and for those purchasing before September 30, 2019,  an additional $1,500 rebate from the state of Massachusetts.

How else can I help?

Not everyone can switch to an electric or hybrid vehicle today, but fortunately there is still much you can do to fight climate change during your daily travels. Carpooling or taking public transit instead of driving even a few times a month can reduce your carbon footprint. Walking or biking shorter distances when possible can help to eliminate it entirely.

Working from home once or twice a week can also go a long way towards a greener future, with telecommuters in 2017 preventing 3 million tons of greenhouse gas emissions from entering the atmosphere. If you do use a traditional car, properly inflating your tires, driving slower, and avoiding idling can save on both emissions and expenditure at the gas pump.
