Frequently Asked Questions
How do you price your solar pv systems?
Our prices may be slightly higher than our competitors and equipment sellers, but it is due to our exhaustive quality assurance process. When you approach us for an assessment, our engineers and design crew will perform a site visit to ensure they have accurate details of your installation location before even handing you a price or a proposal. Through the design phase, we will identify all concerns from integrity of roof, placement risks to shade analysis as we do not condone quoting a system that is just based off dividing available surface area.
Our crew are also trained and certified in design, installation and maintenance of pv systems from the regulatory body of Sustainable Energy Authority of Singapore where our founder; Jason Law, is one of the only few certified trainers. Included in our price is an assurance of our commitment to quality assurance.
What would be the best time to go solar?
There is no better time than now. Solar prices have dropped over the years and has become more affordable. Anyone from commercial to residential building owners can own a solar energy system.
Is it worth to do solar?
That is definitely a yes! The cost of generating your own solar power is less than buying from the power grid. This helps you to save on your utility over a long period. Additionally, there are many other non-monetary benefits.
Is my roof suitable for solar?
Solar can be mounted onto the different type of roofs (tiled, metal or reinforced concrete roof). A roof with little or no shade would be most ideal for solar. You can arrange with us for a site assessment or consultation.
Will the installation of solar panels affect my roof?
SunPro ensures that the most safe and effective methods are used to install the panels. The roof will not be punctured for a typical installation.
Do I need a permit to install solar?
Yes. We will need to submit an application to Singapore Power (SP) through a Licensed Electrical Worker (LEW). SunPro will do all the application work on behalf of the customer.
What if my solar energy system produces more electricity than what I need?
In a grid-tied setup, the excess electricity is exported back to the grid. The owner will receive payment for the excess electricity that is sold back to the grid.
Do I need a batteries for my solar energy system?
Most buildings in Singapore are able to go for a grid-tied setup which does not require batteries. Batteries are only required when storage of the power is needed.
What are the components needed for a typical solar energy system?
Solar panels, inverters and balance of system which includes mounting racks, AC/DC junction boxes and cables.
How long can my solar energy system last for?
An installation with a reliable company using quality products should last for decades. Moreover, most solar manufacturers provide warranties for as long as 25 years.
How do I know how much I can save?
As you produce and use your own clean power, you import less power from the grid. Any export of power will also be reflected on your monthly utility bill. Most solar energy systems comes with a monitoring system which allows you to track the power output on a monthly basis.
What are the warranties given?
Most solar manufacturers offer a product warranty of 10 years and power warranty for up to 25 years. Our most popular panels of which we are listed as preferred installers are REC and JASolar. They offer a 25 year and 12 year warranty respectively.
Most inverters come with a minimum warranty of 5 years. Warranties for specific brands and models will be listed in our proposal to you. You can check them out individually: SMA, ABB, Huawei, Fronius
Would there be maintenance required?
A solar energy system is very robust with no moving parts and therefore require very minimal maintenance.
