What Business Owners Care About Most
We understand that business owners are not only concerned about “whether solar can save electricity” — they care most about these 3 things.
Roof Safety & Leakage Risk
Many factory roofs have been used for more than 10–20 years and may already have rust, leakage, or structural aging issues. If solar panels are simply “forced onto the roof,” future roof or structural problems may lead to both sides blaming each other — the roofing contractor says it is a solar issue, while the solar contractor says it is a roofing issue. This becomes the biggest headache for business owners.
-
Roof leakage repair cost:
RM 5,000 – 50,000 -
Water damage to equipment + 1–3 days of downtime:
RM 10,000 – 150,000 -
Responsibility being pushed around →
老板两头都赔
Estimated Actual Losses
De Solar’s Approach:
We conduct a roof structure inspection first. If necessary, we will carry out roof refurbishment or structural reinforcement together.
Roof panels, waterproofing, and solar mounting structures are designed together to reduce leakage risk.
Any future roof or solar-related issue will be handled directly by us.
Worried About Affecting Production / Cold Chain / Business Operations
Factories cannot stop production, cold rooms cannot rise in temperature, and shopping malls cannot switch off the lights. Many business owners worry: “If I install solar and replace my roof, do I need to stop operations for a few days?”
-
Factory downtime loss per day:
RM 5,000 – 50,000 -
Cold room equipment recovery cost: From RM 10,000
-
One wrong planning decision →The electricity savings may not even be enough to cover the downtime losses
Estimated Downtime Cost
De Solar’s Approach:
We plan the work zones and phases in advance, and arrange construction during off-peak hours as much as possible.
For temperature-sensitive areas such as cold rooms, emergency plans will be prepared in advance.
Goal: To allow your business to operate while construction is ongoing, and reduce downtime to the minimum.
Investment Return & Cash Flow Pressure
A one-time investment of hundreds of thousands or even millions can make business owners worry: “How many years will the ROI take? Will it affect company cash flow?”
-
TNB tariffs increase every year → Electricity costs may double within the next 10 years
-
Monthly electricity bill RM 10,000 × 25 years = RM 3M+ in electricity cost
-
Waiting one more year means missing out on RM 60K – 100K in potential savings
The Cost of Doing Nothing
De Solar’s Approach:
We use your actual 12-month electricity bill data to create an accurate ROI simulation.
We offer 3 flexible options: CAPEX / installment / PPA.
Goal: To lock in your electricity cost for the next 20–25 years and make your profit more stable.
