Turning to the sun to provide energy for your business is one of the best investments that you can make to support your business power requirements. Powering your business with solar panels means you can lower or zero your energy bills. Protect your company from rising electricity costs and reduce your impact on the environment.
Due to the huge reduction in the cost of solar panels “by over 90% throughout the past 15 years from 250THB per watt to approximately 16THB per watt since we started business Est. 2006”. This is because of increased enhanced technology and mass production.
No better time than now. To install a medium to large solar system for your business. Generally in most cases. A standard Grid-Tie system can pay for itself within 2 to 4 years. Warranty power out for PV modules are generally 25 plus years.


This a PV Solar System to either power part or all of the business electrical appliances, either in conjunction with or without connecting to the National Grid as a supplement pending your requirements. 2. Sell your PV solar to the National Grid in countries where this incentive is available.
Now business owners can generate their own clean energy effortlessly. Solar available these days can support anything from a light bulb to an entire village pending the system size.

The two main limiting factors regarding PV system size & type as to what you can power is:

  • Suitable area available for the solar panels/modules “roof or ground”. With no shading from the sun.
  • Budget to purchase and install a system. “For example, Grid Tie with storage backup are most economical due to no requirement for batteries”.


Basically a system which converts sunlight into usable electricity. Solar panels produce DC (Direct Current) electricity. This DC electricity is run through a computer controlled solar inverter to produce AC (Alternating Current) electricity equivalent to specification to match the national grid supply

  • Reduce or zero your Electricity Bill
  • Generates passive saving opposed to using national grid utility power.
  • Guaranteed long life span, minimum spare part replacement and very low maintenance over 25 years
  • Reduces you carbon foot print


  • Reduce or zero your Electricity Bill
  • Generates passive saving opposed to using national grid utility power.
  • Guaranteed long life span, minimum spare part replacement and very low maintenance over 25 years
  • Reduces you carbon foot print


  • No Grid needed
  • Specific detailed system design & sizing to match appliance loads
  • Require PWM or MPPT charge controllers to support batteries and Inverter to power AC appliances.
  • Larger upfront investment due to batteries recover on average within 4 to 8 years in comparison the Grid electric.
  • Can combine or replace diesel generators for backup power.
  • Higher maintenance, battery replacement within 25 years

Types of PV Solar Systems MonoSun offer & how they work?

1) Grid-Tie PV Solar System (Also known as an On-Grid System)

“No storage batteries required”

Grid-Tie PV Solar systems are the most popular and widely used
  • Very cost effective with modern technology.
  • They are the most reliable longest lasting PV system type for homes and business.
  • Ideal for self-consumption in order to substantially reduce or eliminate electricity bills based on the system size of your choice.



Generate free electricity to either reduce Electricity Bills re self-consumption or sell the power produced when Feed In Tariffs FIT incentives are available. Note: Grid-Tie systems only work when connected to a mains live grid as part of its integral anti islanding international standard safety feature. If there is a grid power cut. The Grid Tie solar system will shut down.
Should you have a requirement for backup while the grid is down or non-existent? (See section 2 & 3 on PV Residential page about Off-Grid & Hybrid Solar. They can be set up on large scale too).

Basic Principal

The solar energy is used first to support appliances. The remaining balance electricity required is supported from the utility grid. All fully automated by the Grid Tie inverter.
The electricity bill can be reduced by however much one requires. “up to 100% pending the system size of your choice”.

A Grid Tie system is connected via the MDB (Main Distribution Board) fuse box in the home. The PV Solar will supply power to the factory appliances first. It does not matter if the solar system is lower output versus the overall power requirement.
When the PV solar inverter detects the solar output insufficient. The inverter will automatically detect and draw only the additional amount of electricity required from the National Utility Grid to provide the balance required as a supplement to the solar. If any excess PV solar power produced. The excess can be fed back to the grid in locations where it is allowed to obtain FIT or take back as from the daytime excess credit through the meter at night if your main meter is bi-directional.

Regardless availability of government incentives or not. Solar is still very worthwhile. However do keep in mind solar panels are only 30 to 40% the cost of a complete solar system.
Note: if the grid shuts down. A Grid-Tie solar system will also stop working (Anti Islanding). Protect line workers.
All our grid tie related inverters have Anti Islanding to a high international standard and certification. This is a standard feature with reputable Grid-Tie inverters. They cannot function or generate electricity during a Grid failure “blackout or power outage” due to safety in regards to utility line workers etc. If backup power is required to cover any grid outages.
We suggest you consider one of our Grid-Tie hybrid or Off-Grid system with backup batteries. (See section 3 below on Hybrid systems).
We can provide ROI predictions with our Grid Tie quotes. This info is realistic and based on a combination of historical data from our solar systems installed locally over the past 15+ years and solar radiation data from NASA.

Simply let us know the following for a system quote.
  • How much % would like to save on your average monthly electricity bill?
  • How much are your average monthly electricity bills, including VAT and Tariffs on your bills?
  • Cost per Kwh Unit? (Bill total cost/Units used)
  • Total Kwh or units used per month from your bill? (Or simple send as a copy of some average bills.
  • Inform or picture of your electric meter to decipher if it is 1 phase or 3 Phase power supply to your property.
  • Would you require battery backup to cover for grid failures/blackouts?
    To provide a very rough idea cost difference. A hybrid system with battery cost in the region of 100,000 to 200,000THB plus above than of a Standard Grid Tie only inverter with no battery backup.
  • Is most of your power used daytime or nighttime?

The above info provides us with a good starting point to prepare a site survey and advice on the most suitable system type, sizes and approx. costs of the various options we can offer based on your objectives and property.

Generally the 2018-2019 FIT solar incentive in Thailand have been very low (During 1919-2020 the rate was only 1.69THB Per Kw), Thus not really beneficial to sell excess solar for 1.69THB/ Kwh when you can use all the free solar power produced for self-consumption to offset the higher cost of grid equivalent power usually around 4.7THB per watt FT and VAT included.
Private estates and islands tend to be higher rate in the range of 7 to 10THB per unit. Thus faster ROI for locations with these higher rates. In some cases we have obtained ROI well within 2 years.
