As solar energy grows more popular among companies, many are confronted with a difficult decision: should they pursue a Solar Power Purchase Agreement (PPA) or self-invest in their own solar power system? Both alternatives offer advantages and disadvantages, and determining which is the best match might seem like an impossible task.
At Constant Energy, we are often asked about this issue, and the fact is that there is no one-size-fits-all solution. It relies on your company’s objectives, financial status, and risk tolerance. So, let’s compare them side by side to help you determine which solar method will provide the most energy while also saving your company expenses.
What’s the Difference Between a Solar PPA and Self-Investment?
Before we go into the finer specifics, let’s be sure we understand the fundamental distinctions.
Solar PPA: A PPA allows us to build, own, and operate the solar system on your property. You do not pay for the system itself. Instead, you pay a fixed amount for the power it creates, which is typically less than the rate charged by your utility company.
Self-Investment: Here, you buy the solar system outright. That is, you pay the initial expenses of equipment, installation, and continuing maintenance. However, after the system is paid off, you will get all of the power it creates at no further expense, with the notable exception of regular upkeep and repair.
Now that we’ve covered the fundamentals, let’s go further into the different approaches.
Upfront Costs: Pay Now or Later?
The fact is that solar panels are not inexpensive. When you invest in your own system, you are looking at a significant upfront cost. Equipment, installation, permits, and grid connections may all add up. However, there is a possible advantage here: you are practically creating free power for decades. That’s a strong motivation.
If you don’t want to take the risk of the upfront cost, a Solar PPA is a more affordable option. A PPA requires no payments in advance. We fund the system, arrange the installation, and cover the recurring expenditures. You just pay for the power it produces. It’s similar to leasing the system in that your organization will not have to make a large initial investment.
So, if cash flow is limited or you’d rather deploy your resources elsewhere, a PPA is definitely your best option. If you have the financial resources and a long-term perspective, self-investment may result in substantial long-term savings.
The Issue of Maintenance
Maintaining a solar power system is no easy undertaking. There’s cleaning, monitoring, maintenance, and keeping up with technology improvements. With a self-invested system, you carry full accountability. While solar panels are generally low maintenance, issues may emerge, and repairs are not always inexpensive.
When you choose a PPA, maintenance is our responsibility. We own the system, consequently it is in our best interest to keep it working smoothly. We manage monitoring, maintenance, and updates, so you can concentrate on operating your company.
The essential takeaway here is that if you don’t want to deal with system maintenance, a PPA may be a better option. Conversely, if you don’t mind doing the maintenance yourself or getting a professional to do it for you, a self-investment might be ideal.
Energy Savings, Both Short and Long-Term
This is often a primary consideration in the decision-making process, since solar power may drastically cut your energy expenses. With a PPA, you can start saving immediately. We typically provide more affordable rates for solar-generated power than your utility rate, so you’ll save on expenses right away. Furthermore, your rate is locked in or accurately indexed, providing security from the erratic fluctuations of utility costs.
Self-investment yields potential long-term energy savings. Once your system is paid for (typically in 5 to 10 years), you will be producing free power. You will not be charged for the electricity your panels generate, and as grid rates climb, your savings will only grow.
Essentially, a PPA gives immediate savings with no upfront expenditures, while self-investment ensures long-term energy independence after the system is paid off.
Who Owns the System?
When you self-invest, you own the system. That means you receive all of the financial advantages, including tax credits, incentives, and depreciation. However, it also means you are accountable for everything. Ownership provides total control and long-term financial rewards, but it does not come without risks and obligations.
With a PPA, we own the system. You still gain from solar energy, but we assume the risk. You won’t have to worry about the system becoming obsolete or dysfunctional.
In summary, if you want to optimize financial returns and are willing to manage the system, ownership is the way to go. If you wish to reduce risks and stay hands-off, a PPA is a better option.
Keep Your Options Open
When you sign a PPA, the contract normally lasts 10 to 25 years. This is a long-term commitment, but it is also flexible in the sense that we may adjust the agreement to your specific energy requirements. If you want to remain in your present location for the foreseeable future, this might be an excellent alternative. However, if your organization is likely to move, you should also consider how to transfer or withdraw the arrangement.
Self-investment provides a little more independence. You own the system, so if you move, you can sell it or take it with you. Key point here is that relocating a solar system is neither inexpensive nor straightforward.
So, if you want to remain in your current location for an extended period of time, both solutions are suitable. If your company is more transitory, ownership could offer greater freedom, provided that you are aware of the relocation costs.
Making the Right Decision for Your Business
Going back to the question, should you use a solar PPA or invest in your own solar power system? The best option is determined by your financial circumstances, long-term goals, and desired level of control over your energy system.
At Constant Energy, we’re here to help you consider your alternatives. Whether you’re choosing a PPA for its low upfront expenses and hands-off approach, or self-investment for long-term financial rewards, we have the knowledge to help you every step of the way.
