Pros and cons
✓ Pros
- A Philippine brand with local service, so support does not depend on an overseas seller
- 120W folding design with carry handles at both ends
- Monocrystalline cells, the same cell type as the imported panels here
- Firefly is a long-established lighting and electrical name in the Philippines
✗ Cons
- Firefly publishes no full data sheet for this model, so efficiency, weight, and weather rating are all unstated
- 18V output needs a charge controller before it can safely charge a 12V battery
- No stated IP rating, where every EcoFlow panel here documents one
- 120W for more than the 125W Bifacial panel here asks, with less documentation behind it
The Firefly FSP120/18 is our Best Local Brand pick: a 120W folding monocrystalline panel from a Philippine company, for around ₱13,500. You buy it for the local service, not for the spec sheet.
Why choose a local brand?
Because a warranty is only as good as the person you can reach. Firefly Electric & Lighting is a Philippine company with decades in lighting and electrical goods and shops that stock it nationwide. If a panel fails in year two, that is a local conversation rather than a claim routed through an overseas seller.
For a lot of Filipino buyers that is worth more than a couple of efficiency points, and it is a fair reason to pick this over a cheaper import.
What do you actually get?
120W at 18V, from monocrystalline cells, in a four-panel folding design with carry handles at both ends. That form factor is the practical one: unfold it, aim it, fold it back into a slab you can carry.
That is also, honestly, most of what is documented.
What is not documented?
This is the part to go in with your eyes open. Firefly publishes no full data sheet for this model. There is:
- no stated efficiency, so you cannot compare it against the 23% and 25% figures the EcoFlow panels publish
- no stated weight
- no stated IP rating, where every EcoFlow panel here documents one
None of that means the panel is bad. It means you are trusting the brand rather than checking the numbers, which is a different kind of purchase. We would rather say that plainly than repeat listing claims as specs.
The other practical note: at 18V it needs a charge controller before it can charge a 12V battery, and that is an extra purchase.
Is it sulit?
Around ₱13,500 as of August 2, 2026. Check the latest price on Shopee. That is roughly ₱113 per watt, which is mid-pack here and more than the 125W Bifacial asks for slightly more output and a full published spec sheet.
So the value case is not the watts. It is the local brand, the local service, and a company you can actually find. Whether that is worth the difference is a genuine judgment call, not a number we can settle for you.
Who should buy it
Buy this if local support and a familiar Philippine brand matter more to you than a published efficiency figure. It is the right choice for a buyer who wants someone nearby to talk to if something goes wrong. If you compare on documented specs, the imported panels here win. See how it ranks in our best solar panels in the Philippines roundup, or browse more on our Home Improvement page. Our solar panel buying guide explains which specs are worth insisting on.
Alternatives to consider
If documented specs matter more than local branding, the EcoFlow 125W Bifacial is our Best Overall at around ₱9,000, with 25% cells, IP68, and a full published sheet. For the longest stated warranty in this group, the EcoFlow 110W Portable Solar Panel Kit states 5 years at around ₱15,000.

Frequently Asked Questions
Is Firefly a Philippine brand?
Yes. Firefly Electric & Lighting Corporation is a Philippine company, long established in lighting and electrical products and widely stocked here. That is the main reason to choose this panel over an imported one: service and replacement happen locally.
What does FSP120/18 mean?
It is the model code. The 120 is the rated wattage and the 18 is the panel's voltage, so it is a 120W, 18V panel. Firefly sells the same monocrystalline line in smaller sizes too.
Can it charge a car battery directly?
Not safely on its own. An 18V panel needs a charge controller between it and a 12V battery, otherwise you risk overcharging. Budget for one if that is your plan.
What specs does Firefly not publish?
Quite a few, and it is the main drawback. There is no published efficiency figure, no weight, and no IP weather rating for this model, where every EcoFlow panel in this roundup documents all three. What we can confirm from the product photos is that it folds into four panels with carry handles.
