Meet David Jimenez: The GDF Leader Driving Solar Project Financing and Supporting Nonprofits

For David Jimenez, vice president of sales for Greenday Finance (GDF), his job is about much more than simply making a sale.

“For me, it’s about doing good deeds on a daily basis. You not only help the client but a whole ecosystem. It will generate an environmental impact for a generation,” says Jimenez, who, in addition to his passion for the environment, counts among his interests animal welfare, poverty alleviation and solar services.

As a father of two, he’s especially interested in improving the environment. For his wife and kids, he often equates a successful solar project financing deal to planting a given number of trees that reduce carbon emissions.

Helping nonprofits serve their communities

But the impact of his solar finance job isn’t just environmental. He often works with nonprofit organizations looking to cut their energy bills. When he helps them do this, he’s aiding their efforts to serve more people. 

Jimenez is excited that he’s helped install more than 800 solar projects over the last 10 years. Last year alone, he financed 91 solar projects. He has achieved this success by saying “yes” to his clients and offering out-of-the-box solutions, he says.

More traditional solar financiers will make a standard offer to all clients. But at Greenday Finance, Jimenez looks for custom solutions.

“We look for ways to say yes,” he says. If customers believe it’s not possible to finance a project, his job is to make the project happen.

Customized finance deals help solar projects move forward

Greenday Finance’s solar power purchase agreements (PPA) offer clients flexibility, no upfront payments and immediate savings. To customize a deal, Jimenez might offer more energy cost savings in the beginning of a contract or offer a longer term contract.

Finding solutions also means collaborating. Jimenez works closely with engineering and finance teams, and he recognizes that pooling team members’ experiences and expertise helps overcome obstacles.

“Collaboration not only sparks creativity but also ensures we get things done right,” he says. “At GDF, this team spirit is what sets us apart. With a diverse mix of backgrounds and plenty of know-how, I know I can count on my colleagues to handle any challenge.”

Moving solar financing along quickly

Jimenez is proud of his ability to meet an important challenge: financing solar projects quickly.

For example, recently an engineering, construction and procurement (EPC) firm and developer couldn’t find financing for a $1.5 million solar project in California, where projects are often hung up by financing.

Jimenez and his team developed a solution that allowed the project to be installed in 2024. This success began with a 15-minute call to Jimenez. The EPC firm and developer signed a nondisclosure agreement the next day and began reviewing the project that week. “In just five days, we delivered a prequalified PPA and helped them present it to the customer a couple of days later,” he says. “In less than three weeks, we went from perfect strangers to industry partners, providing day-one savings to the building owner.”

And of course this project, like all solar projects, yields environmental benefits. 

 “I’m proud of the impact I’ve had,” says Jimenez.

Designing Commercial Solar Systems for Bill Savings and a Win-Win-Win

When David Jimenez works with clients interested in financing commercial solar projects, he seeks a win-win-win scenario, says the vice president of sales for Greenday Finance.

Reaping benefits with or without storage

That means ensuring solar systems are designed, first and foremost, to save commercial property owners money on their electric bills. This will reap benefits for the customer, the installer and solar finance provider Greenday Finance. 

That also means adding energy storage to solar systems only when it makes sense. Some states are implementing changes to net energy metering (NEM)–a solar compensation method–and incentivizing adding energy storage. But it’s important to take a hard look at the numbers before investing in batteries, said Jimenez.

Focusing first on saving customers money

“We make a difference in having a different point of view: not as many panels as possible, but what are the best ways to save the customer money,” he said.

Jimenez sometimes is invited into a solar project after the initial design phase, and works with Greenday’s consulting engineers to ensure the project is properly sized. It’s important to do this before exploring solar power purchase agreements (PPA).

Too often, projects are oversized, he said. The goal may be to generate as much solar as possible, but designers may not look hard enough at whether this strategy is cost-effective.

Taking a hard look at energy storage

Another potential pitfall: Designers may suggest adding energy storage even though the cost of storage undermines the economic benefits of a project.

For example, a commercial property owner may use electricity mostly at night.  This may create an incentive to install energy storage to deploy solar stored during the day when the sun sets.  But that may not be the least expensive option; it involves purchasing expensive batteries.

Instead, it makes more sense to first crunch the numbers to compare different scenarios: solar systems with storage, without storage and with different numbers of panels, he said.

In this case, even if using solar only during the day means the customer will be hit with utility demand charges at night, it still may make the most economic sense to install a small system rather than oversizing the solar and adding storage. When adding storage, designers often oversize solar to ensure there’s enough available to run storage through the night.

The importance of understanding solar compensation tariffs

Greenday Finance also helps its solar finance customers better understand how to respond to changes in NEM, especially in California, where the latest version of NEM no longer compensates solar owners with 1 KWh of electricity for each KWh of solar exported to the grid.

Instead, the utility might pay the customer 4 cents/kWh for solar exported to the grid, then charge the customer 17 cents/KWh for electricity the customer purchases, said Jimenez.

“It’s important to understand how NEM rules will be applied and use engineering to think of how to get the best benefit,” he said.

When sizing a PV system, it’s also a good idea to look into local zoning regulations and potential development nearby, according to the National Renewable Energy Laboratory.  Zoning and permitting requirements can have a negative impact on PV system performance. And new development can shade a roof, impacting the system output.

Gaining solar project financing quickly

Once the solar system design has been re-configured or completed, Greenday Finance can provide financing to qualifying projects in 30 days or less, said Jimenez. Greenday Finance offers solar PPAs that require no up-front investment and that lock in rates that are lower than the local utility’s rates. Customers can start cutting energy bills right away.

“Once the customer agrees, we can move fast and get the system up and running, saving the customer money,” Jimenez said.
