Enerray UAC Thailand was created in 2016 as a joint venture between the Italian company Enerray S.p.A., a sub-holding of the Maccaferri Industrial Group, and UAC Global Public Company Limited, a Thai listed company. The purpose of this subholding is to apply to the Asian market the outstanding technologies, procedures and services developed in the solar EPC and O&M sector by Enerray.


Since its foundation in 2007, Enerray’s priority has always been to provide a 360° turnkey service, putting its experience at the client service in order to maximize the investment profitability and minimizing any technical risk related to the solar plant installation. Thanks to the experience acquired in Italy and abroad as a result of the internationalization process started in 2011, the company has strongly increased its order portfolio, establishing itself as a leader in the market both as an EPC and as O&M Contractor.

Advantages of Solar Energy
PV systems
Clean technology with multiple advantages

PV technology looks set to be the one to offer the most promising long-term and large-scale use of renewable sources, especially in countries such as Thailand that enjoy plenty of sunshine.



Photovoltaic systems last a long time (25-30 years) and require lower maintenance, given to the limited use of moving mechanical parts.



The architecture of photovoltaic systems is modular, and they can be sized up or down as required – panels can be placed on areas of various sizes and dimensions



A photovoltaic module produces from 6 to 18 times more energy than is used to produce it, meaning that after about one year it begins to produce energy with zero impact.

Photovoltaic system makes no noise

No impact

A photovoltaic system makes no noise and has a low visual impact.

Invest safely and reduce your energy costs
with Enerray UAC

A solar power plant is a low risk investment with good returns, especially for industrial and commercial users that can install it on the roof of their factories/commercial buildings.

Photovoltaic system reduce or even eliminate the costs

Low Energy Bill

The energy produced by the photovoltaic system allows energy-intensive companies to reduce or even eliminate the costs sustained to use electricity from the grid.

Energy transferred to the grid has a value

Excess Transfer

Excess energy transferred to the grid has a value, based on the rules and tariffs on the electricity market.


Added Value

A photovoltaic system also increases the value of the property on which it is installed.



A photovoltaic system can create profit from otherwise unusable areas (for example roofs or desert areas).

Enerray UAC
thinks green

Enerray makes concrete efforts in regards to ethics and the environment, not only by producing clean, renewable energy, but also by carrying out its business in accordance with current laws and in compliance with high ethical standards, as well as operating in a responsible manner, economically, socially and environmentally. All of this is aimed at protecting the health and safety of our employees, our customers and all the people involved with our company.


Green Image

A photovoltaic system is a symbol of environmental responsibility that can be exploited in marketing, helping to promote a green image for the company and increasing positive perceptions from customers, who are increasingly attentive to the sustainability of the products they acquire.


Avoided CO2 emissions

Photovoltaic energy allows a reduction in pollution by decreasing carbon dioxide (CO2) and other pollutant emissions that contribute to the greenhouse effect for an estimated value of about 0.5 kg for every kWh produced.



Photovoltaic systems do not produce residue during operation and at the end of life. The modules can be regenerated or recycled, and the materials used in the production process can be reused.



In the presence of asbestos roofing, these may be removed and disposed of in suitable centres, thus reducing the risk of contamination.


The Thailand Board of Investment (BOI) offers a variety of fiscal and non-tax incentives for investments in solar energy. This covers the production of electricity or electricity and steam from renewable energy, such as solar energy. The scope and size of investment promotion for the rooftop owner and/or the developer have to be carefully reviewed under the specific new solar rooftop regime, move away from the FiT towards a self-consumption driven market, through a net-metering/net-billing scheme, that could trigger more investments in the already growing solar rooftop market.
