Frequently Asked Questions (FAQ)
Why are more and more companies choosing...?
De Solar?
-
Malaysia's first one-stop company for "roof & skylight manufacturing + solar systems"
The company manufactures roof and skylight structures in its own factory, and then its internal engineering team designs and installs the solar energy system. The structure, safety, drainage, and wiring are all planned together from the beginning.
-
Focusing on C&I projects for factories, cold storage facilities, warehouses, shopping malls, etc.
They are very familiar with high-load, 24-hour operation power consumption patterns and take into account production equipment, refrigeration systems, and future expansion space when designing systems.
-
From structure to power, comprehensive engineering management
A single team coordinates everything from roof structure assessment and load calculation to drainage design, walkway and safety railing design, solar panel layout design, grid connection application, and monitoring system.
-
Reduce risks: Rooftop + Solar power solves the problem in one go
No need to worry about roof contractors and solar contractors shifting blame. Any issues related to the roof, leaks, brackets, or wiring can be resolved with a single call to De Solar.
-
We value long-term cooperation, not just disappearing after the job is done.
We provide system monitoring, regular checks, and after-sales support, so you can confidently entrust your 20-25 year investment to us.
-
Tailor-made investment solutions for enterprises
Depending on your cash flow and tax planning, we can discuss CAPEX / installment / other cooperation models. The goal is for the business owner to see returns in about 3-6 years, after which every month will be pure cost savings.
We understand that what the boss cares about most isn't "whether it can save electricity," but rather...
Concern 1:
Roof safety &
leakage risks
Many factory roofs have been in use for over 10-20 years and have problems such as rust, water leakage, and structural aging. If solar panels are simply "nailed on," and problems arise with the roof or structure later, the roof contractor will say it's the solar panels' fault, and the solar panels contractor will say it's the roof's fault—this is the biggest headache for the boss.
De Solar's approach:
-
First, conduct a structural and roof condition inspection; if necessary, it is recommended to renovate or reinforce the structure.
-
We oversaw the entire process ourselves, from roofing panels and purlins to brackets and waterproofing design.
-
The solar panel mounting method is designed in conjunction with the drainage direction to reduce the risk of future water leakage.
-
If any problems arise in the future, we will be responsible for investigating and handling them; we will not pass the buck.
Concern 2:
Fear of affecting production/
Cold chain/business
Factories can't shut down, cold storage facilities can't be heated, and shopping malls can't turn off their lights. Many business owners are worried: Will installing solar panels and replacing roofs require a few days of work stoppage?
De Solar's approach:
-
Hold meetings with the production/operations teams in advance to plan for phased and zoned construction.
-
Try to schedule construction on weekends or during off-peak hours.
-
Emergency plans will be prepared in advance for cold storage and temperature-sensitive areas.
-
Objective: To minimize downtime, and even achieve "construction while operations continue."
Concern 3:
Return on investment & cash flow pressure
When investing hundreds of thousands or millions at once, the biggest concern for business owners is: "What will the ROI be over how many years? Will it affect the company's cash flow?"
De Solar's approach:
-
Use your actual 12 months of electricity bill and load data to create a detailed savings simulation.
-
We provide comparisons of different system capacities and solutions, allowing you to decide on your investment size.
-
Installment payments/CAPEX/other cooperation models can be discussed to reduce one-time expenses.
-
Objective: To help you lock in electricity costs for the next 20-25 years, resulting in more stable profits.

After that, there will be regular inspections and after-sales support.
Is solar power suitable for your business?

Not suitable for the time being
The current premises are only leased on a short-term basis (less than 3-5 years), or the business may relocate soon.
Monthly electricity bill is less than approximately RM3,000, and the electricity load is not high.
The roof area is too small to install a system of meaningful capacity.
Companies worth careful evaluation
Monthly electricity bills are approximately between RM3,000 and RM15,000.
With stable production, cold storage, and retail operations, the factory is not expected to relocate within the next 5–10 years.
Plans include roof renovation, increased natural light, and improved factory environment.
Almost every company must install
Monthly electricity bills exceeding RM15,000, or multiple factories/large cold storage facilities/large shopping malls
Operating 24 hours a day, it is very sensitive to electricity costs.
The goal is to break even within 3–6 years and lock in electricity costs for the next 20–25 years.
