Questions to Ask Before Choosing a Solar Company in Malaysia
A trustworthy solar installer should explain system design, safety, documentation, warranties, after-sales service and the assumptions behind its savings estimate.
Choosing an installer is a technical and financial decision. These questions help homeowners and businesses compare providers on more than sales claims.
Technical Questions
Ask who designs the system, who performs testing, what protection equipment is included and how roof structure and shading are assessed.
Commercial and Service Questions
- What company will appear on the contract and invoice?
- Which equipment brands and warranty terms apply?
- Who handles application documents and commissioning?
- What happens if output is lower than expected?
- How are maintenance visits and support requests handled?
Evidence to Request
Look for real completed projects, clear company details, qualified technical personnel, written warranty terms and a proposal that can be checked against your property and bill.
Frequently Asked Questions
Should I compare five or ten installers?
A small number of comparable written proposals is usually more useful than many incomplete quotations.
What is a warning sign?
Be careful with guaranteed savings, unexplained deposits, pressure to sign immediately or a proposal that does not identify equipment and responsibilities.
