Deciding to move to solar is like deciding to plant a tree for your future: it grows slowly, gives shade for decades, and changes the landscape of your life. Yet, as with any long-lived choice, the people who help you plant it make all the difference.
Many imagine the system’s panels and inverter are the whole story. In truth, the success of rooftop solar depends equally on the company that designs, installs, and supports it. A careful vendor protects your money, your roof, and your peace of mind. Conversely, the wrong partner can leave you with poor performance, headaches over warranty claims, and expensive repairs. So before you sign anything, take a breath—and check the essentials.
What to check first:
-
Legal status and reputation (is the company a legitimate business entity with a real office?)
-
Track record and portfolio (have they handled systems like yours before?)
-
Product transparency (which panel and inverter brands do they use?)
-
Full-service capability (do they manage survey, design, permits, installation, and testing?)
-
Clear warranties (product, performance, and workmanship)
-
Certified technicians (trained for safe, compliant installation)
-
Transparent, itemized quotations (no hidden costs)
If you want your investment to pay back for 20–25 years, these basics are non-negotiable. After all, a strong partnership now will save you time, money, and worry later.
Meanwhile — How experience, products, and services protect your investment
Experience is a quiet teacher. Vendors who have worked on many roofs have seen sun angles, load-bearing surprises, and tricky wiring. They have learned what works and what fails. So always ask for a portfolio—not just pretty photos but system capacities, locations, and client references. A varied portfolio (residential, commercial, even industrial) signals technical depth.
Equally, insist on transparency about the components. “Tier 1” panels, reputable inverters, proper mounting and certification (IEC, SNI where relevant) matter because they affect longevity and the ease of claiming warranties. A trustworthy vendor will explain pros and cons of brands and won’t hide behind vague terms.
Turnkey service is another protection. Good vendors handle everything: on-site survey, system design, permit paperwork like a Sertifikat Laik Operasi (SLO) if applicable, skilled installation, and commissioning tests. This end-to-end approach prevents delays and finger-pointing later.
Warranties are your safety net. Confirm:
-
Product warranty (panels: usually 10–12 years; inverters: 5–10 years)
-
Performance warranty (panels retain a high percentage of output over 25 years)
-
Workmanship warranty (coverage for installation errors for 1–5 years)
Also, ask about the process: how do you file a claim, and how fast will they respond? A vendor’s responsiveness matters more than glossy brochures when trouble comes.
Therefore — Transparency, technicians, and the final decision
Price should never be the only compass. Very low offers often hide inferior components or careless installation. Instead, demand a detailed quotation: every component, every labor item, and every permit fee listed clearly. Compare apples to apples—same capacities, same brands, same scope.
Check the technicians. Are they certified? Do they follow safety standards? Properly trained installers reduce risk of electrical faults and structural damage. If a vendor invests in their people, that tells you they invest in long-term quality.
Finally, trust but verify. Visit their office if possible, read independent reviews, and speak with past customers. Ask direct questions about after-sales service; the answer will reveal more than a glossy brochure ever could.
