PV in 60 Seconds: What Does Self-Consumption of Solar Power Mean?

.. and for the Companies?

For companies we have the most advantageous situation.


Because carrying out its activities during the day can easily get a 100% self-consumption, without the need of batteries for electric storage.

How self-consumption changes the convenience of photovoltaics?

That’s one thing, indeed the main thing, which is to know who puts a photovoltaic system on your roof, balcony, pavement or yard: the convenience of photovoltaics depends not only on the cost of installation, does not depend on what I produce the panels does not depend on where the plant is installed. The convenience of installing a photovoltaic system depends first of all self-consumption.

Obviously, in reality, all of the factors combine to determine the advisability, but the main element in ensuring a good economic return from the expenditure for the facility is self-consumption. We talk about “payback” because, photovoltaics is not a cost, but an investment, and like any investment, time has more or less long back. Putting solar panels on the roof, today, if you agree autoconsuma least part of their production.

Example: if I have a plant producing 10 kwh of clean energy a day, I will have more convenience if I use ‘own’ these 10 kwh of energy. Energy “zero cost” made available by my system for my consumption. In this way, and only in this, I will have a 100% savings in electricity bills.

Example of investment

Payback period only from 3 to 5  years for 100 KW PV rooftop installation with self-consumption

Commercial and industrial rooftop solar systems with self-consumption show an attractive return of invest in Phuket-Thailand. A 100kW system with Talesun modules at rooftop commercial building has a payback period of only five years and huge energy cost saving potentials in the following years.

Clean Energy for self-consumption made by a Solar Rooftop.

The Talesun cells supplied more than 355 photovoltaic modules, high-performance connected with the world’s leading brand of solar inverters SMA. The installation on the roof is designed from Phuket Solar co., Ltd, a company with experience in the construction of photovoltaic systems for different applications in Phuket.

The system is spread over a surface of more than 2000 square meters on the roof and is expected to produce about 150,000 kWh of clean electrical energy per year. The energy will be used exclusively for electrical system of ‘all activities’ of the internal structure.

Attractive industrial solar consumption

For commercial and industrial companies in Thailand, it is economically attractive to use solar systems for self-consumption of clean electricity to power their production plants, allow high cooling intensity activities or other energy. In this way, companies can largely disconnect from rising energy and save considerably on costs of electricity prices in the long run. In addition, a solar system improves the eco-balance and sustainability of the business.

Energy cost savings 750,000 THB annual

The 180kW installation in Phuket is a strong evidence of this:

Given the current average energy prices for companies in Phuket 5 THB / kWh, the system is expected to be amortized in just six years and after that realize energy cost savings of approximately 1,350,000 THB per year, with a potential upside due to the expected increase in electricity prices. A major factor in realizing this potential a reality for the future is to use the high-quality solar modules for the system, which are capable of providing an energy efficient, not only at the beginning, but also in the later stages of systems operation and high performance.

Tax deduction from Company Profit by 20% per annum

The entire cost of the photovoltaic plant can be deducted at a tax rate of up to 20% per annum, reducing the return on investment for only 3 years

“The solar system is an investment for a prosperous future of all commercial activities in Phuket especially those involved directly with the tourism industry, the primary economic source of the island”
