Find answers to the most frequently asked questions about switching to solar energy.


How do solar panels work?

Solar cells are generally made from silicon, a semiconductor that generates electricity.  This process is known as the 'photovoltaic effect'.

Solar panels work by absorbing sunlight and generating direct current (DC) energy which is then converted to usable alternating current (AC) energy with the help of an inverter. The AC energy is then distributed to your home or business.

What are the benefits of going solar?

Thailand is bathed in sunshine most of the year, and is the perfect country to go solar.  Installing solar power in your home or business will help you to:

  • Drastically reduce or even eliminate your electricity bills.

  • Earn a great return on your investment.

  • Protect against rising energy costs.

  • Increase the value of your property.

  • Protect the environment against pollution and climate change.

  • Improve the image of your business.

Electricity Station

Will I still rely on the Grid?

We offer three different solar system options, depending on your requirements and budget - On-grid, Hybrid, and Off-grid:

1. On-grid = solar panels + electricity grid.

2. Hybrid = solar panels, batteries + electricity grid.

3. Off-grid = solar panels + batteries only.

On-grid systems are the simplest and cheapest options, where you take power from solar panels during sunlight/daylight hours and from the electricity grid during darkness/night time hours.

Hybrid systems are when you take power from solar during the day. This power is used for both daytime power requirements and charging the batteries. The battery power is then used during darkness hours and the electricity grid is used as a back up.

Off-grid systems are used when there is no electricity grid connection either available or required. Solar panels are used to provide daytime power and to charge the batteries for power during darkness hours.

What happens if my electrical needs change?

Your system can be designed to meet your current needs, however small, and scaled up as your needs change. It can grow with your needs.

We install top quality, state of the art equipment which is scalable and modular, ensuring that simple changes can be made to your existing system.


Will I have enough power on cloudy days and at night time?

Thailand has some of the longest sun hours of any country in the world. There are huge advantages to installing solar panels in this country.

Although solar panels need sunlight to create electricity, it doesn’t necessarily need to be direct sunlight. Solar panels still absorb UV rays even on cloudy and rainy days, but production of electricity will be lower during these days.  The panels will generate electricity optimally on days when there are clear skies.

The panels won’t generate any electricity at night time. You will need to have a storage system, such as batteries, or be connected to the electricity grid.  We will discuss your needs with you and make sure your needs are met.


What electrical storage options do I have?

If you want to enjoy full-time availability of solar power, having reliable and ample battery storage is advisable. This will help to ensure that you have enough power to use, even when the sun is down.

However you can also connect or remain connected to the electricity grid to ensure that you have a continuous supply of power.


Can I sell surplus power back to the Grid and make money?

While there is no payback system yet in place, Thailand has committed to increasing its use of renewable energy.

The country is close to creating a 'feed in' system where you will be able to sell your extra power generated to the electricity company. This system is already running successfully in many parts of the world and is expected to be running in Thailand in the not too distant future.

Are there any risks / Is it dangerous?

The way a solar panel works is completely safe and does not create any hazardous or toxic fumes, gases or waste. The only by-product of a home solar energy system is cheap, clean electricity.

For the vast majority of users, solar panels should not be cause for any safety concerns. Solar panels are essentially an additional electrical appliance in your home, and should be considered in a similar vein as refrigerators and air conditioners when it comes to the danger that they bring to your home.

Air Conditioner

Can I run my air conditioning units on solar?

There are a few factors that will impact how much running an air conditioner will cost you, including the rate you pay for electricity, how often you use the air conditioner, the size of the air conditioner, and its associated power usage.

Solar power is one way you can keep your electricity costs down. You don’t have to be a casualty of high electricity bills. Solar energy is an effective way to generate renewable energy for your air conditioner to use, while also providing power to the rest of your appliances.

Solar panel systems will generate thousands in electricity savings for over 25 years, and outlast your air conditioner plus all the other appliances they power.


Do you install HPT water heaters?

Yes!  The sun’s energy is in abundance in Thailand.  You can use solar energy to have hot water, you can cool, you can pump water, you can do almost anything that requires electricity.  Imagine the possibilities.


Can I have A/C and D/C running in my house?

Yes, you can!  You can run all of your existing appliances in your house and never need to change a thing.   The energy from our solar panels comes into your home as DC (Direct Current).  We install an inverter that converts DC to AC (Alternating Current).

How is D/C changed to A/C?

DC is Direct Current.  Our panels generate DC.  Some of your needs may use this energy directly, but most of your appliances will need AC (Alternating Current) operating at 220 V.  We use an inverter to convert DC to AC. This is exactly the same process as what happens in a gas or diesel generator used for electricity.


How do I power my fridge and freezer at night?

With an on-grid solar system, the power for running appliances at night will come from the electricity grid, at reduced nightly rates.

A solar power set-up suitable for refrigerator use requires batteries to store the power that the refrigerator will use at night.

Can I stop using the electrical grid altogether?

You can install an off-grid system to take care of all of your electrical needs. This involves a combination of solar panels to produce electricity, and batteries to store the electricity produced by the solar panels. This power is then used for power requirements at night.

What problems might I face with solar power?

Installation and maintenance of your solar system should be carried out by experienced professionals, such as Thai Solar Power. This will ensure that you have the correct system for your needs, while enjoying trouble free production of your own electricity.

We recommend an annual inspection and cleaning of the panels to keep your system in optimum shape.

Using a Touch Phone

Can I monitor the efficiency of my system?

When your system is installed, we will set up an App on your phone which provides detailed information on the performance of your system from any location. This data not only keeps you informed but can help you identify areas where you can reduce your power usage and make your system perform to its optimum level.


Can I charge my electric bike or car from the sun?

Yes! All of the major car and motorcycle manufacturers are putting enormous resources into Electrical Vehicles (EVs). Some major cities and countries have announced plans to ban combustion engines altogether in the near future. The future for cars and motorbikes is electrical, which means you will soon be fueling up at home from your solar panels.

Solar Panel Repair

Do I need to do maintenance on my solar system?

Keeping your solar panels working well, and your roof in good condition, is all about establishing proper maintenance procedures. Thai Solar Power provides inexpensive maintenance contracts to ensure that your system performs consistently to the highest standard, and lasts as long as possible. 


Can I get financing for solar? 

Just as you can finance the purchase of your car, your solar system can be financed by certain banks and financial institutions. Thai Solar Power can provide information if you would like to find out more about financing.
