Electricity is one of the largest fixed costs in any commercial operation. Thailand’s grid rates sit between 4.18 and 5.50 THB per kWh — and the fuel adjustment charge is reviewed upward almost every quarter. For hotels, resorts, and retail centres, that bill is significant, predictable, and almost entirely outside your control.

Solar EaaS changes that. Kunini designs, funds, installs, owns, operates, and maintains a complete solar energy system on your property. You pay a fixed monthly service fee and focus on running your business. We handle everything else.

What Is Solar Energy as a Service?

Energy as a Service is an outcome-based model. Instead of purchasing a solar system — or even buying the electricity it produces — you pay a single, fixed monthly fee in exchange for guaranteed energy outcomes. Your cost is known from day one and does not vary with weather, season, or system output.

Under a Kunini EaaS agreement, the scope of what we manage goes well beyond a standard solar installation. Depending on your requirements, a single EaaS contract can cover:

You use the energy. You pay the agreed service fee. We manage the rest — for the full term of the contract, typically eight to ten years, after which all assets transfer to you.

How EaaS Differs from a Private PPA

At first glance, EaaS and a Power Purchase Agreement can look similar. Both require no upfront capital. Both give you access to solar energy without owning the hardware. But the differences matter — particularly for businesses with complex energy needs or ESG reporting obligations.

A PPA is a product. EaaS is a partnership.

For a hotel trying to cut electricity costs, achieve Green Hotel certification, meet ESG reporting targets, and add EV charging for guests — EaaS delivers all of that through one provider and one contract.

How the EaaS Process Works

Step 1

Free Energy Consultation and Audit

We start with your electricity bills, operating hours, consumption profile, available roof space, and your goals. For hotels, that means understanding your HVAC load, pool pumps, kitchen equipment, and guest room demand. For retail centres, it means mapping lighting, air conditioning, escalators, and anchor tenant usage. We look at the full picture before recommending anything.

Step 2

System Design and Financial Modelling

Kunini's in-house engineering team designs a system tailored to your consumption profile. We model the financial outcomes: projected savings against your current PEA or MEA tariff, the proposed service fee structure, the environmental impact, and the contract terms. You see the numbers before you sign anything.

Step 3

Agreement and Project Delivery

Once you're satisfied with the proposal, Kunini manages the entire delivery — engineering, procurement, installation, testing, commissioning, and all relevant utility compliance including Zero Export compliance where required. We work around your operations to keep disruption minimal.

Step 4

Ongoing Managed Operations

From the day the system goes live, Kunini handles everything: real-time performance monitoring, remote diagnostics, scheduled maintenance, equipment insurance, and monthly reporting. You receive a clear monthly report showing energy produced, savings delivered, and system health.

Step 5

End of Contract Asset Transfer

EaaS is a long-term partnership, not a transaction. As your business grows or your energy needs evolve — additional EV charging, rooftop expansion, or battery storage — the agreement can be adapted. At the end of the contract term, all energy assets transfer to you outright.

Who Is EaaS For?

EaaS works best where there is strong, consistent daytime electricity demand, reliable long-term occupancy of the property, and a clear desire to reduce operating costs without tying up capital.

Hotels and Resorts

A typical hotel in Thailand uses between 150 and 400 kWh per square metre per year, with air conditioning accounting for 45 to 55% of total consumption — and 65 to 80% of that demand falling during daytime hours, exactly when solar generation peaks. For a hotel spending THB 300,000 to 500,000 per month on electricity, even a 15 to 25% reduction through EaaS translates to THB 45,000 to 125,000 in monthly savings — up to THB 1.5 million per year. A solar EaaS contract also provides documented, verifiable renewable energy consumption for TAT Green Hotel certification and international ESG reporting.

Retail Centres and Commercial Properties

Shopping malls and large retail units operate during fixed daytime hours with predictable energy loads — lighting, air conditioning, escalators, refrigeration. The consistency of demand makes system sizing straightforward, and the savings are immediate and repeatable. With Thailand’s commercial electricity rates subject to quarterly Ft adjustments, a fixed-rate EaaS agreement also delivers a level of cost predictability that grid electricity alone cannot provide.

Is your business a candidate?

If your monthly electricity bill exceeds THB 80,000, you have suitable roof space, and your operation runs during daytime hours — you are likely a strong fit for a free EaaS assessment.

Why Choose Kunini as Your EaaS Partner

Kunini has been designing, installing, and maintaining solar and electrical systems in Thailand since 2002 — one of the longest-established solar EPCs in the country. We installed the first solar rooftop in Hua Hin in 2010 and have since delivered hundreds of projects for commercial, hospitality, industrial, and residential clients nationwide.

As both an EPC contractor and a solar developer, Kunini manages every stage of an EaaS engagement in-house — from initial energy audit through to long-term system management. Every project is engineered, commissioned, and maintained by our own teams. Where additional labour is required on larger installations, we work with approved contractors under the direct supervision of a Kunini engineer. All commissioning, operations, servicing, and long-term maintenance remain entirely within Kunini. You are always dealing with us, not a subcontractor.

We operate from offices in Hua Hin and Pattaya, with nationwide project experience and a thorough understanding of Thailand’s PEA and MEA regulatory environment, Zero Export compliance requirements, and the realities of operating commercial solar systems in a tropical climate.
