Washington, DC - If you own a solar energy system, it’s very likely that the SunShot Initiative has impacted at least one of the steps that helped you get there. Since SunShot launched in 2011, the program has funded hundreds of projects at national labs, universities, and private companies that have added clarity, speed, and cost savings to each step of the “going solar” process.

Deciding to go solar is the first step in the process and often the most challenging one. A lot of variables come into play: Should I make the leap to solar energy? Is my home suitable for solar? Does it make financial sense to go solar? Who should I go with for installation? SunShot awardees are addressing all of these questions.

The National Renewable Energy Laboratory (NREL) uses SunShot funding to research market barriers that prevent solar adoption, fostering competition within the industry to develop a more streamlined process. Awardees such as Sun Number and EnergySage have developed tools that help consumers find personalized information needed to assess the suitability of their homes for solar and to find the best installers. These companies are also driving down solar costs by providing consumers with new tools to help them make informed decisions on how to get started.

Calculating Finances

Just how much can one save by switching to solar? It depends on a complex mix of your home, local laws, and daily energy usage. Algorithms and remote sensing, however, have made it easier to determine your cost savings.

SunShot-funded small businesses use the latest technologies to make this process easier and faster. Aurora Solar developed a remote design tool that creates custom 3D solar system designs, making it easier to determine accurate financing options and potential savings. Another awardee, Genability, created a third-party savings calculator known as Switch, which instantly generates savings estimates that have been found to be more than 99.5% accurate. And, when it comes to obtaining financing to pay for going solar, SunShot awardees are developing solutions to enable loans, master limited partnerships, and new streams of capital for solar finance.

Rooftop Reality

Once a solar installer is selected and financing is obtained, the installation process begins—much more efficient and affordable thanks to early-stage funding from SunShot. Zep Solar’s rooftop mounting equipment shaves $0.28 per watt off of the total installed price thanks to reduced hardware and labor costs. This savings led to their acquisition by SolarCity, one of the country’s largest solar companies. SolarBridge developed a microinverter that can be integrated into solar panels, eliminating the need to set up modules to a single string inverter. Finally, NREL research is used to establish evaluation systems for solar module durability, as well as inspection guidelines, so that industry can offer uniform quality to every customer.

Talking to the Grid

After installation, solar arrays must be connected to the grid. This step is important because utilities need to plan for increases in solar energy on the grid. Since there are many different utility jurisdictions across the country, the process is rarely standardized, and red tape can create lengthy interconnection times.

GridUnity, formerly Qado Energy, developed a cloud-connected tool that uses algorithms to determine what impact a solar installation will have on the grid. It identifies which circuit a solar project will join, calculates its hosting capacity, and provides an instant response on whether the circuit can handle more solar. This can speed up the impact study process in some utility territories from 55 days to just 60 minutes. In addition, to minimize potential negative grid impacts of PV systems, several smart inverters are under development that will allow grid operators to better control solar energy’s local impacts on the electric grid.

Reaping the Benefits

Going solar can help save homeowners money on monthly utility bills, but only if the system is operating correctly. Some awardees have tools that allow you to monitor your energy usage to ensure things are running smoothly. Should the time come to sell your home, a study at Lawrence Berkeley National Laboratory determined buyers are willing to pay a premium of $15,000 for a home with an average-sized, resident-owned solar array. The team is also making home sales easier for real estate agents. They created five standard data fields for solar properties that can be used by the more than 700 multiple listing services around the country to ensure real estate transactions remain secure and efficient.

A Full Solar Circle

Research from Yale University has shown that, if your neighbor notices your new solar panels and you tell them about the cost savings you’re experiencing, the cycle often starts anew as someone else considers going solar. Once a costly process, making the switch to solar is now easier and more affordable thanks to the research and development funded by the SunShot Initiative.

From start to finish, the “going solar” process is powered by SunShot.
