Let us be honest about something first. A Power Purchase Agreement is not always the wrong choice. For a company that genuinely cannot or doesn’t want to raise capital, or one that would rather focus entirely on its core business and hand the whole energy question to someone else, a PPA from a credible provider can make sense. There are very legitimate reasons the model exists.
But most of the companies we speak to who are considering a PPA are not in that position. They have access to financing. They have a balance sheet that could carry a solar asset. What they have been sold is the idea that a PPA is simpler, safer, and smarter. And in most cases, for a Philippine commercial operator in 2026, it is none of those things.
Top 5 Mistakes When Choosing PPA Over Ownership
These are the five most common mistakes companies make when choosing a PPA, mistakes that rarely show up in the proposal, but always show up in the numbers.
1. Treating “No Capex” as the Same Thing as “No Cost”
This is the central illusion of the PPA model and it works because it is partly true. You do not write a cheque on day one. The system goes on someone else’s balance sheet. The finance director does not need to find the capital and the board does not need to approve a capital expenditure. It appears to be a free lunch.
It is not. A PPA converts a one-time capital decision into a recurring expense that runs for ten or maybe fifteen to twenty years. And because the developer needs to recover their investment and deliver a return to their investors, the total amount you pay over the life of the contract is always higher than the cost of owning the same system outright, even when financed through a bank loan.
The white paper Solaren has published on this is worth reading in full. The comparison is not subtle. Factory A signs a PPA at PHP 5.50 per kilowatt-hour with a four percent annual escalator. Factory B buys an identical system through bank financing. After ten years, Factory B is PHP 36 million ahead. After the loan is paid off, Factory B generates electricity at roughly PHP 1.35 per kilowatt-hour for the next fifteen years. Factory A is still paying the developer, and the rate has now climbed to PHP 8.10 per kilowatt-hour. The True Cost of Free Solar sets out the full comparison.
The only solar power that is truly free is the power you own.
2. Not Reading the Escalator Clause
Most PPA proposals lead with the headline rate. PHP 5.50 per kilowatt-hour. Twenty percent below your current utility tariff. The savings look real on the first page.
What matters more is what happens to that rate over time. Almost every PPA in the Philippine market includes an annual escalation clause. It is framed as an inflation adjustment or an index-linked revision. What it actually guarantees is a growing return for the developer while your savings erode year after year.
At four percent annual escalation, a rate that starts at PHP 5.50 reaches PHP 6.60 by year five, PHP 8.10 by year ten, and nearly PHP 9.90 by year fifteen. The original discount disappears well before the midpoint of the contract. By the final years, you are paying more than the current grid rate for power produced on your own roof.
And this is before you account for what is happening on the other side of the equation. The Philippine energy market is liberalising. A Retail Electricity Supply contract can already reduce power costs significantly for eligible consumers. From June 2026, businesses with loads as low as 100kW will be able to seek alternative suppliers under the expanded retail competition rules. The DOE’s emergency powers have already created additional options. A PPA signed today locks you into a fixed structure at precisely the moment the broader market is offering more flexibility. That, in our opinion, is the wrong direction to be moving.
3. Assuming the Developer Will Still Be There in Year Ten
We have said this before in the context of choosing solar contractors generally. It is even more important in a PPA context because the stakes are higher.
With a purchased system, if the contractor who built it closes down, you still own the asset. You still have the manufacturer’s warranties. You find another company to service it. Life goes on.
With a PPA, the developer owns the equipment. Your energy supply, your metering arrangements, your compliance documentation, and your savings are all tied to the continued operation of that company. If the developer closes, is acquired, or sells its portfolio to an investment fund (which happens regularly in mature solar markets) your contract changes hands. You continue paying, but now to a company you have never met, possibly not based in the Philippines, and focused entirely on extracting cash flow from the portfolio they just bought.
In Singapore, which is the most mature solar policy market in Southeast Asia, commercial operators have largely shifted toward treating solar as core infrastructure rather than a leased service. That shift happened because the early PPA market produced exactly the kind of portfolio transfers and contractual complexity that Philippine businesses are now being exposed to for the first time. The lesson from more mature markets is consistent. Ownership is the destination. PPAs are a transitional structure that made sense when capital was unavailable and financing was inaccessible. Neither of those conditions applies to most Philippine commercial operators in 2026.
Industry estimates suggest around ninety percent of solar installers in the Philippines will not be operating in their current form within five years. For an owned system that is an inconvenience. For a PPA, it is a potential crisis.
4. Thinking the Performance Guarantee Protects You
PPA contracts typically include a performance guarantee. The developer promises that the system will generate a defined minimum amount of electricity. This sounds like protection. It is more limited than it appears.
Performance guarantees are almost always based on ultra-conservative generation assumptions. If the system underperforms by a few percent, the client receives little or no compensation because the shortfall falls within the tolerance band. If a significant failure occurs, the downtime provisions typically allow the developer to repair the issue without refunding the lost savings during the repair period.
More importantly, you have no say in what equipment was installed. The developer makes those choices to fit their financial model. Entry-level inverters, thinner cabling, and lightweight mounting. None of it is visible to you, and none of it affects their performance guarantee calculation in a meaningful way. The system performs adequately in years one and two. By years five to eight the shortcuts begin showing up in the generation data, and the client absorbs the loss because the contract is still running and the guarantee threshold is still technically being met.
When you own the system, you specify the equipment. You choose the inverter. You demand the commissioning reports. Every improvement in performance benefits you directly. Under a PPA, every improvement benefits the developer.
5. Missing What Ownership Would Actually Have Done for the Business
This is the mistake nobody talks about because it is basically invisible. It is the value of what did not happen.
A company that owns its solar system is building an asset. It appears on the balance sheet. It depreciates in a way that benefits the P&L. The energy savings flow directly to the business and compound over time. After payback, the system generates electricity at a cost that no developer can match through any PPA structure.
A company that signs a PPA has none of that. The recurring payments are an operating expense, no different in character from the utility bill they were trying to replace. There is no asset. There is no balance sheet benefit. There is no compounding return. There is just a discounted electricity bill that gets less discounted every year.
For Philippine businesses thinking seriously about energy strategy in 2026, the question is not really PPA versus ownership. It is whether you want to keep paying for electricity forever, or whether you want to own the means to produce it.
The energy market in the Philippines is changing quickly. Retail competition is expanding. Alternative supply options are multiplying. The fixed structure of a long-term PPA is becoming less attractive precisely as the market offers more flexibility to buyers who are not locked in.
Ownership is not complicated. Philippine banks fully understand solar assets. Financing is available. Payback periods on correctly specified commercial systems run to three to four years. After that, the electricity is essentially free for the life of the system.
For the full financial analysis of what that looks like in practice, The Ultimate Guide to Commercial Solar ROI in the Philippines sets out the numbers in detail. And if you are currently evaluating a PPA proposal alongside an ownership quote, comparing solar quotes in the Philippines covers how to make that comparison on a like-for-like basis.
FAQs (Solar Ownership vs PPA)
-
Is a solar PPA worth it in the Philippines in 2026?
For most commercial operators with access to financing, no. The economics of ownership have shifted decisively. Philippine banks now understand solar assets and offer clean energy financing at competitive rates. Payback periods on correctly specified commercial systems run to three to four years. After that, the electricity is essentially free. A PPA that starts cheaper than the grid will cost more than the grid within ten years due to annual escalation clauses. The one exception is a company that genuinely cannot raise capital or prefers not to manage infrastructure assets. For everyone else, ownership produces a significantly better financial outcome over the life of the system.

What happens to my PPA if the solar company closes or sells the contract?
Your contract transfers to whoever buys the portfolio. You continue paying, but now to a company you did not choose, that may not be based in the Philippines, and that has no relationship with you beyond the payment obligation. Service levels, warranty claims, and compliance matters all become more complicated. This is not a theoretical risk. Solar developers in more mature markets regularly package PPA contracts and sell them to investment funds. It has already happened in the Philippines. The contract you signed with a local solar company can end up owned by an offshore investment vehicle with no local presence. There is usually nothing in the PPA that prevents this.
-
Can I buy out a solar PPA early if I change my mind?
Usually yes, but rarely on favourable terms. Most PPA contracts include a buyout clause that allows the client to purchase the system at its remaining book value. In practice, this means you pay most of the depreciation cost twice — once through your electricity payments and again through the buyout price. By the time you reach the midpoint of a fifteen or twenty-year contract, you have already paid far more than the system’s original cost, yet you pay again to take ownership of ageing equipment with limited warranty life remaining. Read the buyout clause before signing. The terms tell you a great deal about how the contract was written and whose interests it was designed to protect.
