14.1 A customer asked: Is it more cost-effective to install a bigger home?
14.1 A customer asked: Is it more cost-effective to install a bigger home?
Standard answer: Not necessarily. How much can be installed on the roof is not the same as how much is best suited for the bill. For household projects, the value of the system first depends on how much it can be used spontaneously during the day, rather than the total installed capacity itself.
How to answer: You can’t just say ‘of course it’s the most cost-effective to have a full floor’ just to cater to customers. This will push the project from a matching solution to a display solution, and it is easy for there to be a revenue gap in the future.
Why: When the system is too large, the spontaneous self-consumption rate decreases and the proportion of delivery is increased. The high-priced daytime electricity purchases that can really offset it may not necessarily increase simultaneously.
14.2 Customer asked: Will it leak after installation?
14.2 Customer asked: Will it leak after installation?
Standard answer: Any roof construction must handle waterproofing carefully, but the professional approach is not to just apply a circle of glue, but to first determine the roof structure and waterways, and then use appropriate fixing and sealing nodes to reduce risks.
How to answer: You can’t say ‘it will never leak’. It can be said that ‘we will try to reduce the risk to a very low level according to standard construction methods and make the boundaries clear in advance’.
Why: As long as there is a building connection, there is a boundary; the difference between a professional company and an unprofessional company is whether this boundary is truly understood and managed.
14.3 Customer asked: Can it still be used during a power outage?
14.3 Customer asked: Can it still be used during a power outage?
Standard answer: A standard grid-connected system usually triggers protection to stop output when the public power grid is out of power; if you have clear power backup needs, you need to design energy storage and backup power circuits separately.
How to answer: You can’t vaguely explain it, and you can’t let customers default that ‘having photovoltaics means that there will be no power outage’.
Why: This is one of the most common areas of misunderstanding among customers and one of the most likely to trigger strong complaints.
14.4 Customer asked: Others are cheaper, why are you expensive?
14.4 Customer asked: Others are cheaper, why are you expensive?
Standard answer: The difference in total price usually comes from equipment, construction methods, safety configuration, data support, grid connection services and after-sales responsibilities. It is recommended to compare the same range, the same brand, the same safety and the same responsibility, rather than just the final number.
How to answer: You can't belittle your peers right away, and you can't immediately cut off key configurations in order to close a deal.
Why: What customers really want is a comparison framework. Once you provide a framework, professionalism will be established.
14.5 A customer asked: Are all photovoltaic installations by enterprises eligible for 150% tax deduction?
14.5 A customer asked: Are all photovoltaic installations by enterprises eligible for 150% tax deduction?
Standard answer: It cannot be understood so simply. The enterprise-side tax incentives in 2026 are targeted at investments in qualified high-efficiency machinery, equipment and energy-saving materials; whether they are applicable depends on the equipment category, energy efficiency label, e-Tax Invoice, operation status and whether it conflicts with BOI/EEC and other preferential treatment.
Unable to answer: It cannot be said that ‘if a company installs it, it will automatically receive 150% tax deduction’.
Why: This is the policy point that is most easily distorted by marketing rhetoric, and it is also the content that has been specifically corrected in the first chapter.
14.6 Internal blacklist of high-risk terms
14.6 Internal blacklist of high-risk terms
In principle, the following words should not appear directly in sales promises: ‘absolutely’, ‘definitely’, ‘definitely’, ‘guaranteed’, ‘zero risk’, ‘make money when you install it’, ‘it is worth installing without having to look at the bill’, ‘150% tax deductible for enterprises’, ‘can still be used even if there is a power outage’.
The purpose of blacklisting these words is not to stop the team from speaking, but to prevent the organization from being biased by high-risk expressions.
- Definitely get your money back
- Absolutely no water leakage
- It will definitely be connected to the grid very quickly
- Businesses can enjoy 150% tax deduction
- It will definitely work during a power outage
- The bigger you pretend, the more money you make
