It is a reasonable instinct. Solar has got cheaper over the years, technology keeps improving, so surely waiting another year or two lands you a better deal? It feels smart. But run the numbers and waiting usually costs you more than it saves. Here is the honest version.
Panels are cheap already, and falling slowly
Solar panels have dropped dramatically in price over the long run, a trend so consistent it has a name, Swanson’s law, which you can read about on the Wikipedia Swanson’s law page. But two things matter for your decision. The fall has slowed, so the big drops are behind us, not ahead. And the panels are only one part of a system’s cost. The inverter, the mounting, the wiring and the labour to install it all cost money too, and those are not getting cheaper. So even if panel prices dropped another 10 percent next year, the price of a finished system would barely move.
Meanwhile, the meter keeps running
Here is the part the “wait for cheaper” logic ignores. Every month you do not have solar, you keep paying JPS the full retail rate for your power, and that money is gone for good. Wait a year and you have handed over a whole year of bills you could have avoided. Set that against a small possible saving on equipment a year from now, and it is no contest: the bills you skip by going solar now almost always dwarf the modest discount you might get by waiting. And since grid power tends to get more expensive, not less, waiting can cost even more than it looks.
The cheapest quote is not the cheapest system
There is another trap in chasing the lowest price, whether now or later. The companies offering rock-bottom prices are often the ones cutting corners on equipment or unlikely to be around to honour a warranty, as we get into in tier 1 vs cheaper solar panels: does the brand matter. A system that fails early or loses its warranty support is not a bargain at any sticker price. Value matters more than the headline number, which is the point of how to compare two solar quotes fairly.
The one good reason to wait
To be fair, there is a sound reason to hold off, and it is not about price. If you cannot yet size or afford the system properly, or your roof needs work first, it is better to wait and do it right than to rush a compromise. Waiting to get the system correct is wise. Waiting purely for a lower sticker price usually is not. We lay out the payback maths in solar payback period in Jamaica: a realistic estimate.
The takeaway
Solar will keep getting a little cheaper, slowly, but the savings from waiting are small and the cost of waiting is real: a stack of JPS bills you never get back. For most homes, the best time to go solar is when you can do it properly, not when some perfect price finally arrives, because that price never quite does. Get the system right, and start saving now rather than paying the grid while you wait.

Will solar get cheaper if I wait?
A little, and slowly. Panel prices have fallen dramatically over the long run, but the big drops are behind us and the decline has slowed. Panels are also only one part of the cost; the inverter, mounting, wiring and labour are not getting cheaper. So a finished system’s price barely moves even if panels drop another 10 percent.
Does waiting for cheaper solar actually save money?
Usually not. Every month without solar, you keep paying JPS the full retail rate, and that money is gone for good. A year of avoided bills almost always outweighs the small discount you might get by waiting. Since grid power tends to rise in price, waiting can cost even more than it first appears.
Why not just buy the cheapest system available?
Because the cheapest quote is often not the cheapest system. Rock-bottom prices frequently mean corners cut on equipment, or a company unlikely to be around to honour a warranty. A system that fails early or loses warranty support is no bargain. Value over the system’s life matters far more than the lowest sticker price.
Is there any good reason to wait?
Yes, but it is not about price. If you cannot yet size or afford the system properly, or your roof needs work first, it is better to wait and do it right than rush a compromise. Waiting to get the system correct is sensible. Waiting purely for a lower sticker price usually is not.
Do electricity prices really keep rising?
Grid power tends to get more expensive over time rather than cheaper. That means the bills you avoid by going solar now are likely to be even larger in future, which strengthens the case for acting sooner rather than waiting for a hardware discount that may never amount to much.
When is the best time to go solar?
When you can do it properly: the system sized to your usage, the roof sound, and a reputable installer chosen. That is a better trigger than waiting for a perfect price, which never quite arrives. Getting the system right and starting to save now beats paying the grid while you hold out.
