How does solar power work?
- 1. Solar Panel Arrays on your roof collect the suns energy and send it to an inverter
- 2. The inverter will change this energy from DC power into usable AC power, from the inverter, the AC power can go in two directions depending on your setup.
First, if power is required, then solar power will be drawn into your business and used.
Second direction is for excess power not used, instead of entering your home, it will travel out to the electricity grid. Currently, in Thailand the utility has a zero-export policy meaning you cannot send excess power back into the grid.
What happens at night?
What about shade?
Does my roof need to face South?
A South facing array will produce most of its power through the middle of the day, while an east or west facing array will produce more solar production at either the beginning or end of the day; which is when you will generally use more power.
How do I get solar power to my home or business?
Once you approve the quotation, Kunini will then set up the Installation which will be carried out by Kunini’s own Solar Install Team.
Kunini will take care of as much of the process as possible including any permits that may be required.
Can I upgrade in the future?
Another factor when upgrading is the size of the current PV system, as there are some restrictions on the maximum size of domestic solar pv systems.
How long will my solar system last?
Inverters are a little more complicated and ultimately their longevity will depend on factors such as their location (how dirty, how much sunlight and heat in that location).
Most provide warranties of 5 to 10 years with an expected performance life of 15+ years.
Are there any Incentive programs in place at the moment?
The utility, PEA, MEA allow customers to install solar pv for self-consumption only.
How do I maintain the solar panels?
Monitoring: Regularly checking yield results on the inverter is advised to detect any possible performance issues. If in doubt a quick phone call to one of our staff members can quickly confirm if performance figures are within normal range.
What is module (solar panel) efficiency?
A typical 250w solar panel has an efficiency rating of around 15.3% where a 235w solar panel of the same dimensions would have an efficiency rating of around 14.1%.
Do I still need a grid connection? Is main electricity still required?
What if it is cloudy?
During a power cut, will my solar panels provide me with electricity?
Where does my inverter get installed?
What permits will I require?
What is the performance guarantee?
Are my panels covered by insurance?
What is the 'Tier System' for rating solar panels?
The idea behind the ranking system is to help business owners make informed decisions that will give them piece of mind for their investment.
At the most basic level, Tier 1 means a manufacturer supplies quality products and has the intention of staying around for the long-term. This is important because, after all, what good is a 25 year warranty if the company won’t be around to support it?
What is your warranty policies on the systems?
Inverters: 5-10 years, manufacturer’s warranty.
Mounting Warranty: 10 years, manufacturer’s product warranty.
Installation: 2 years, installer’s warranty.
