Tell us about your site.
The quickest route to a real answer is twelve months of billing data — that is enough for us to model your load and tell you whether storage earns its capital. If you would rather ask a question first, this page is for that.
Write in Thai or English — either is fine.
One address, read by the people who build the models.

Useful things to include: your tariff class, your rough monthly bill, whether you already have solar, and where the plant is. Any one of them moves the conversation forward; all four and we can usually tell you something concrete in the first reply.

Leave your details and we will come back to arrange the billing data. You will get the same feasibility report we would build for a paying engagement: sizing, load analysis and the full financial case.
Prefer to write a proper message? Email us directly — it reaches the same place and you can say as much as you like.
Four steps, and you can stop after any of them.
An email or the form above. Nothing is committed and nobody calls you unannounced.
Your billing data, and telemetry from your inverters if you have solar. This is the part that takes you real effort.
Load analysis, sizing, tariff and the full financial case, with the assumptions stated so you can argue with them.
Including deciding against it. We tell you when the numbers do not work — that is the report doing its job.
PJJ Solutions Co., Ltd.
Founded in 2024 out of the Chulalongkorn School of Integrated Innovation, and backed by a 1M THB NIA × Chula grant. We build CESS, the control-intelligence layer that forecasts a factory's load, dispatches its battery against its tariff, and recovers curtailed solar.
You fund and own the hardware. We are paid a share of the savings CESS actually produces, measured against an agreed baseline — which means a system that underperforms costs us before it costs you. Built and supported in Thailand.
