Solar Rooftop in Chonburi for Factories and Warehouses
Commercial rooftop solar for Chonburi's manufacturing and logistics base — designed around your roof, load, and PEA tariff.
Chonburi anchors the western edge of the Eastern Economic Corridor, with Amata City Chonburi, Pinthong, and the Laem Chabang logistics belt driving heavy power demand. With large warehouse roofs and daytime-running operations, commercial solar here often pays back faster than most owners expect. We design each system from your real bill.
PPA vs EPC: choosing the right structure
A PPA lets you go solar with no capital outlay — Bustan Energy invests in the rooftop system and you buy the electricity below grid price. EPC means you own the array and capture the full long-term saving. For Chonburi's mix of manufacturers and logistics operators, the right answer depends on your balance sheet and horizon, so we model both clearly.
- PPA: no upfront cost, discounted power, we handle O&M
- EPC: full asset ownership and maximum lifetime return
- Transparent payback and IRR comparison per site
- Battery add-ons for warehouses with evening load
Designed for your PEA tariff
Chonburi commercial and industrial sites typically buy from the Provincial Electricity Authority (PEA) on time-of-use or demand tariffs. How well solar performs depends on aligning generation with your peak-rate hours. We start from your actual bill — peak, off-peak, and demand charges — then size the rooftop to lift self-consumption where it cuts the most cost.
- Modeled on your specific PEA TOU and demand rates
- Generation aligned to your daytime peak hours
- Support with metering and connection documentation
- Honest view of what solar can and cannot offset
Roof and load review
Chonburi has some of the largest warehouse and distribution roofs in the EEC, alongside older factory structures near Laem Chabang. Big roofs are an opportunity, but only with sound structure and the right load match. We review roof condition, span, shading, and your consumption curve before sizing, so the system earns its return across decades.
- Structural check on large warehouse and factory roofs
- Shading, orientation, and span analysis
- System sized to your true daytime load curve
- Realistic 25-year yield and maintenance plan
Industrial estates we serve
We deliver across Chonburi's commercial and industrial zones, including Amata City Chonburi, Pinthong Industrial Estate, WHA Chonburi, and operations around Laem Chabang Port. Each zone differs in utility setup, roof type, and tenancy, so we tailor both the engineering and the grid-connection process to your exact location in the corridor.
- Amata City Chonburi tenants and owners
- Pinthong and WHA Chonburi industrial plots
- Laem Chabang logistics and warehouse operators
- Multi-site and distribution-center portfolios
Frequently asked questions
How much can a Chonburi business save with solar?
It depends on your roof size, daytime load, and PEA tariff. We avoid generic figures — send your bill and we'll model the real offset and payback for your Chonburi warehouse or factory before any commitment.
Can I install solar without upfront capital?
Yes, through a PPA we fund and build the system and you buy the power at a discount. With EPC you own it for maximum lifetime savings. We compare both so the decision is purely financial.
Is a large warehouse roof good for solar?
Often it is ideal, given the area and daytime operations common in Chonburi logistics. Structure and condition still decide feasibility, so we assess the roof before designing the system.
How long does payback take in Chonburi?
It varies by tariff, load, and structure, so we don't promise a fixed period. Many daytime-heavy commercial sites see attractive returns — we model yours specifically from your bill.
What's involved in connecting to PEA?
Commercial rooftop solar needs metering and grid-connection approval from the Provincial Electricity Authority. We prepare the technical documents and walk you through each step for your Chonburi site.
