Which Solar Power Installation Company is Best? Introducing How to Choose Without Regret!

When considering the introduction of solar power generation, the most important factor is “choosing the right contractor.”

While the performance and price of the equipment itself are important, the quality of installation, the availability of after-sales service, and the transparency of pricing can greatly affect satisfaction based on the contractor’s response.

In fact,

“I regretted choosing the wrong contractor and was charged a high fee.”
“I encountered problems after installation, but the contractor did not respond.”

There are quite a few people who have these regrets.

Therefore, this time, we will explain in detail the points and precautions for selecting a reliable solar power installation contractor, as well as the flow leading up to the introduction.

Reasons to Carefully Choose a Solar Power Installation Contractor

Solar power generation is equipment that can be used for over 20 years once installed.

Therefore, while it is easy to focus on the initial costs, if the quality of construction and support system are insufficient, it can lead to unexpected troubles and additional costs.

Moreover, some contractors take on installations solely for sales purposes and outsource the actual construction to external parties.

In such cases, unnecessary fees may arise, and the responsibility can become ambiguous, so careful consideration is necessary.

Points to Consider When Choosing a Solar Power Installation Contractor

The points to consider when choosing a solar power installation contractor are as follows:

・Check if they have knowledge of roofing
・Confirm the costs
・Check their track record
・Obtain multiple estimates
・Check their reputation
・Confirm the availability and content of after-sales support

Let’s take a closer look at each point.

Check if they have knowledge of roofing

Make sure they have knowledge not only of solar panels but also of the roofing where they will be installed!

If you hire a contractor without roofing knowledge, it could lead to issues such as leaks or the need for immediate roof renovations.

Check their track record in roofing construction as well!

Confirm the costs

When selecting a solar power installation contractor, confirm the costs.

The key point here is to ask for a breakdown of the costs.

Request a detailed estimate and review the contents carefully!

Check their track record

Installing solar power generation requires advanced skills and knowledge.

To confidently entrust the work, you must check the contractor’s track record.

By confirming how many installation projects they have handled in the past, you can more easily assess the quality of that contractor.

Contractors often publish their track records on their websites, so be sure to check in advance.

Obtain multiple estimates

There is a market price for the installation costs of solar power generation.

However, the actual costs can vary depending on the contractor you choose, so be sure to obtain estimates from multiple contractors in advance.

This way, you can check details such as the breakdown of costs, service contents, and the availability of discounts.

Additionally, by comparing the thoroughness of the estimates, you can assess the quality of the contractors, so it is recommended to obtain estimates from at least three companies for comparison.

Check their reputation

To find a reliable solar power installation contractor, it is important to check their reputation.

By obtaining estimates or directly inquiring, you can somewhat judge the quality of the contractor, but the real situation often becomes clear only once the work begins.

However, by checking the genuine feedback from those who have actually used the contractor, it becomes easier to determine if they are truly the right fit for you.

Google reviews are difficult to manipulate and cannot easily erase negative feedback, making them a highly trustworthy source of reviews.

When checking the reputation,

“Poor response”
“No warranty”
“Shoddy workmanship”

If you notice posts like these, it may be best to avoid that contractor.

Check for aftercare services and their details

It’s also an important checkpoint to see if they provide proper maintenance after installation and how they respond in case of malfunctions.

If you are looking for a contractor you can trust,

・Warranty period
・Warranty conditions
・Warranty details

Make sure to confirm these thoroughly.

What happens if you choose a solar power installation contractor carelessly?

There are multiple solar power installation contractors across the country.

As a result, some people end up choosing a contractor without much research, simply because they don’t know how to select one.

However, if you choose a solar power installation contractor carelessly, you may easily encounter the following issues:

・Increased risk of cost-related troubles
・Higher likelihood of issues due to poor workmanship
・Risk of the installation contractor going bankrupt
・Increased chances of reflection light troubles

Let’s take a closer look at each of these.

Increased risk of cost-related troubles

If you choose a solar power installation contractor carelessly, you are more likely to face cost-related issues.

Most contractors calculate costs based on market rates and provide detailed amounts during the estimation phase.

However, some may intentionally offer a lower price and then charge a high amount after the work is completed, or they might start the work based on a verbal agreement without issuing a formal estimate.

Hiring such contractors can lead to disputes over what was said and what wasn’t, or unexpected expenses, so be cautious.

Higher likelihood of issues due to poor workmanship

As mentioned earlier, installing solar power systems requires advanced skills and knowledge.

If you hire a contractor lacking in skills or experience, you may encounter issues such as:

・Wiring deficiencies
・Mistakes in mounting structures
・Water leaks

Correcting panels that have already been installed can be costly, so it’s crucial to choose a reliable contractor from the start.

Risk of the installation contractor going bankrupt

This is often an overlooked point, but when selecting a solar power installation contractor, you must also pay attention to the stability of the company.

If you choose a contractor too casually, there’s a risk that they may go bankrupt after installation, leaving you without any aftercare support.

In such cases, you may have to pay regular prices to another contractor for services that should have been provided for free or at a low cost, so be careful.

Increased chances of reflection light troubles

To maximize the effectiveness of solar power, it is very important to determine the installation location and angle.

This is crucial not only for increasing power generation but also for preventing disputes with neighbors, so you must entrust this to a reliable contractor.

If you choose a contractor carelessly, there is a higher chance that reflection light from the solar panels will shine into neighboring homes, leading to potential conflicts.

To prevent such troubles, hire a contractor who can design and propose solutions that consider the surrounding environment.

Specific steps to install solar power systems

The steps to install solar power generation are as follows.

1: Consultation and Estimate
2: Order and Contract
3: Installation Work, Inspection, and Handover

Let’s take a closer look at each step.

1: Consultation and Estimate

When installing solar power generation, it’s advisable to request estimates from multiple contractors.

Basically, all contractors will conduct a site survey and provide a detailed estimate.

If there are any unclear points in the estimate, please feel free to ask questions.

2: Order and Contract

Once you have received estimates from several companies, you just need to choose a reliable contractor from among them.

Consider various points such as costs, service contents, and aftercare comprehensively while searching for a contractor that suits you.

Once you have decided on a contractor, inform them and enter into a contract.

3: Installation Work, Inspection, and Handover

After the contract, the installation work will begin.

Typically, the work will be completed in about 1 to 2 days, but if it is a large-scale project, it may take longer, so you should confirm this in advance.

At the end of the work, a functionality check and inspection will be conducted, and if there are no issues, the handover will take place.

At the time of handover, documents such as warranty certificates and maintenance materials will be provided, so please keep them safe.
