The installation cost of solar power is converted to power per kW and it is necessary to determine the installation cost.In that case, it is important to know the approximate market price of what kind of ingredients it will cost.Understanding the overall installation costs can lead to the effects of product comparison and saving.Let's take a closer look at the cost of installing solar power.
Market of solar power installation cost
The cost of installing solar power generation in 2022 is 200 to 300,000 yen per kW.In a realistic image, if the average power consumption per family of four is about 4.5 kW, if you cover all power with solar power alone, you need to install more than 1 million yen.
The same amount of power generates the cost due to various factors.Therefore, it is a good idea to think that the market price depends on the product.
設置費用は状況により変動する
There are three factors in which the installation cost fluctuates greatly.
The higher the number of roofs to be installed, the more expensive the construction will take time.Be prepared to have a scaffold when installing on the roof, and costs 100,000 to 150,000 yen more than installing it in the garden.
Fixed methods include sturdy tiling methods, supporting metal fittings, and anchor construction methods in the order of work.Basically, all construction methods have a minimum strength, but if you value safety, etc., the installation cost will be high.
空き地で太陽光発電を始めるときの違い
When starting solar power in a vacant lot, solar power is divided into industrial use.The amount of solar power generation for industrial use is conditioned at 10 kW or more, and more power generation can be obtained.However, the installation costs will be charged additionally, compared to contracts applied to your home, including fence costs, linkage construction costs, and construction costs.In particular, it can cost up to 10 million yen, especially for construction work to prepare land.
On the other hand, the unit price per 1 kW tends to be cheaper than in the house, so there may be cases where the dominance is high depending on the land and products.
Breakdown of solar power installation costs
Solar power installation costs include a lot of costs, such as construction costs and material costs.If the installation cost is actually divided for each item, the breakdown will be as follows.
| 費用項目 | 初期費用額(1kWあたり) |
| 太陽光発電のパネル費 | 20万円 |
| パワーコンディショナー費 | 4万円 |
| 架台費 | 2万 |
| 発電モニター | 2万 |
| 接続箱 | 6,000円 |
| ケーブル | 5,000円 |
| 工事費 （設置や電気系統の工事） | 5万円 |
| その他（手続きなどの手数料） | 3,000円 |
The total breakdown is about 300,000 yen for solar power generation.It costs hundreds of thousands of yen even if you add a manufacturer's unique campaign discount.Regardless of the difference in the product, it will be necessary to calculate at least as an initial cost.
List of costs by manufacturer of solar panel
The cost of solar power panels varies depending on the product, but the amount of power generation is different for each manufacturer's panel, and the number to be installed changes.For example, if the amount of power generation per sheet is small, it is necessary to install a large number of pieces, so it may be necessary to take a large location on a house or garage roof.
Comparing the cost from the product example of each manufacturer, the following is as follows.
| メーカー | パネル枚数(発電量) | kW単価 |
| SHARP（シャープ） | 24枚 (6.14kW) | 28.8万円/kW |
| Panasonic（パナソニック） | 24枚(6.05kW) | 26.1万円/kW |
| 長州産業 | 22枚(6.03kW) | 24.6万円/kW |
In this way, you can see that the number of panels, the amount of power generated, and the cost will be different even by manufacturer.

For example, if the solar panel called Panasonic's standard type "P252αplus" is a solar panel, the width and depth are 1.58m✕0.81m.Using this panel and the amount of power generation and KW unit price according to the above number of panels, simple calculation is as follows.
| 設置面積 | 発電量（kW） | 費用 |
| 1坪（3.31平米） | 0.63 | 16万円 |
| 10坪（33.06平米） | 6.43 | 168万円 |
| 20坪（66.12平米） | 12.98 | 338万円 |
| 30坪（99.17平米） | 19.53 | 509万円 |
* Estimated by combining the half -type "P120αplus"
When actually installed on the roof of your own home, it is rare that the area is fully used because the amount of power generation changes greatly depending on the direction.Even if it is installed in 20 tsubo, if the south side is about 10 tsubo, the power generation may not exceed 10 kW.Let's keep it as a guide.
Changes in the installation cost of solar power generation
According to the Ministry of Economy, Trade and Industry's announcement, the cost of installing solar power is decreasing from 2009 to 2020, when electricity purchases began.The installation costs from 2012 to 2020 are as follows.
| 設置年 | 新築での設置費用（1kW当たり） | 既築での設置費用（1kW当たり） |
| 2012 | 43.1万円 | 47.9万円 |
| 2013 | 39.1万円 | 43.2万円 |
| 2014 | 36.7万円 | 40.5万円 |
| 2015 | 35.8万円 | 39.8万円 |
| 2016 | 34.6万円 | 37.1万円 |
| 2017 | 34.5万円 | 3.72万円 |
| 2018 | 31.4万円 | 35.3万円 |
| 2019 | 29.3万円 | 33.0万円 |
| 2020 | 28.6万円 | 32.7万円 |
Due to increased demand, cost reductions and performance improvements have been reduced every year and the hurdles of installation are decreasing.The government has stated that it will consider the obligation to install solar power in August 2021, and is aimed at 60 % of the new construction in 2030.Demand can still be expected, so costs can be expected after 2022.

Even if you roughly grasp the cost of installing solar power, the actual amount will be decided after negotiations with the trader in consideration of the shape and environment of the house.Therefore, as a foundation for starting solar power generation, we will explain the procedure until installation and the standard of power generation that makes the electricity bill a zero yen.
Procedure until solar power generation is installed
In order to start solar power generation, it is necessary to take steps such as simulation, comparison of traders, and studying solar power systems.There is no doubt that it takes about six months to take a long time to operate.
The procedure from specific installation to operation is as follows.
- シミュレーション：家や土地が太陽光発電を行える地目か調べ、設置する計画を立てる
- 太陽光発電の業者を検討：複数社から理想の商品やサービスを提供しているものを探す
- 業者とミーティング：業者を決めたら実際に発電システムについて相談する
- 太陽光発電の設置：要望の商品を設置するための工事・施工作業に入る
- 太陽光発電の運用：売電や電力をまかなうことができるようになる
Until the solar power actually starts to move, it will proceed along the above flow.The work of the panel itself depends on the size of the power generation system installed, but it takes about one week for housing.However, if you include carefully selected vendors and facilities, be prepared to take about six months from preparation to starting operation.

It is said that an average of 2 to 8 kW per day is required for ordinary households to live.Therefore, in order to make the electricity bill a zero yen, at least 8 kW solar power is required.
However, this depends on the power consumption of each family.In the case of cold regions, electricity is indispensable to surpass the cold.In addition, even if all electrification and householders are large, power consumption may be large.
Therefore, it is certain that the average power is a guide, and the difference in power consumption in each family will be kept in mind.

With the amount of solar power generation you want, it cannot be installed easily if the cost is several million yen.So, before you sign a formal contract with the trader, try the following five savings methods.
In the end, the installation costs to be paid will be cheaper in units of 100,000 yen, so let's take a look at each one.
Carefully selected solar power installers
If you save the cost of solar power, it is important to carefully select the installers.This is because even if you handle the same product, the cost will vary depending on the company you install.In addition, there are differences in services provided, so it is necessary to consider it in that regard.
Also, when choosing, it is hard to compare the quotes of multiple companies and consider whether they will be advantageous.In that case, if you use a lump -sum quotation site, you can listen to the best or traders only by inputting the conditions, and you can save the trouble of requesting each company.
If you are considering solar power generation, we recommend a batch quote with "Tai Navi".

国の太陽光発電に関連した補助金
| 補助金の制度 | 補助金の上限 |
| DER補助金 | 66万8,000円 |
| ZEH補助金 | 105万円 |
自治体の補助金の例
| 自治体 | 補助金額(1kWあたり) |
| 東京都台東区 | 5万円（20万円まで） |
| 大阪府豊中市 | 1.5万円(6万円まで) |
Detailed conditions for subsidies are updated every year, so you may not be able to apply unless you always check the latest information.In addition, the application is often on a first -come, first -served basis, and the budget may be completed early.Once you decide to install, apply as soon as possible.

Despite both power generation, there is a difference of 120,000 yen, despite the approximately 4 kW level.Therefore, it is one of the best ways to save on the panel costs for each manufacturer and select one that meets the conditions cheaply.
Also, if the manufacturer has a wide variety of solar panels, you can eliminate waste in the installation area.
Use a loan that makes the total payment cheaper
If you use a solar loan to start solar power, make sure that the total payment is cheaper.The interest rate of solar loans is 0.65-3 %, which is low, but in the case of floating interest rates, the interest rate will increase and the payment will eventually be expensive.
Therefore, you may be able to save money by paying attention to interest rates and receiving a loan from a cheap financial institution.
If you choose a floating interest rate and the interest rate will rise in the future, consider refinancing.Even if you consider lump -sum repayment fees, the total payment may be cheaper.
How to install is consult with a trader
It is important to carry out the desired solar power plan, but it is important to consult with the trader about whether it is a method that suits the house.In some cases, when you look at a house from a professional perspective, there may be more suitable products and installation methods.In that case, choosing that can save money.
In the first place, depending on the house, it may not be suitable for solar power, so be sure to meet with a trader so that you can efficiently get power generation.
In addition, the conditions for houses where solar power is not suitable is as follows.

There is a way to free the installation cost of solar power generation by cooperating with the business operator.By renting out the roof of a house or using a lease, the introduction fee can be free.If the installation cost, which is the best bottleneck of solar power, becomes zero, the initial cost will be able to proceed without losing funds.
From now on, we will introduce how to actually have free installation costs.
Solar power generation in PPA
One way is to make the installation cost free by cooperating with a PPA (power sales) company.In this case, there is no ownership of the housing owner.However, lending a roof to a business will make it a share of business, and you will be able to buy electricity at a lower price than electric power companies.
Conversely, the operator will benefit by selling the surplus of power obtained on the borrowed roof to the power company.In other words, housing owners and businesses can be cooperated and benefit.In addition, since the power generation equipment is transferred in about 10 years, solar power will be obtained for free in the long term.
Solar power generation in wreath
There is also a method of leasing equipment to be installed.Leasing (borrowing) can introduce solar power for free without paying the installation cost.In addition, the facilities will eventually be the owner of the housing.
In this case, the housing owner must pay a lease fee to the business.However, unlike PPA, the ownership of solar power is characterized by the owner of the housing owner.Because it owns rights, it is possible to sell surplus and make a profit.
Conversely, in the case of business operators, this method is a system that has benefits for both sides, as it has a structure that can be profitable by the lease fee from the housing owner.
Solar power generation by roofing
There is also a method of obtaining solar power in the roof borrowing method.In this method, housing owners get rent by lending the roof to the business operator, and the business operators can make a profit by selling electricity.However, what I want to note here is the rent amount.Housing owners can get around 10,000 yen a year, which is not very good.
Therefore, it is a good idea to consider it as a solar power generation method that only benefits the business cooperation.

Finally, we will introduce the precautions before installing solar power equipment.Solar power generation is difficult to sell electricity due to running costs, and there are points to note in that it depends on the weather.By keeping the precautions in advance, you should be able to avoid unexpected losses.Therefore, let's take a closer look at each point before the installation of solar power.
Solar power is running costs
It should be noted in advance that solar power can save on installation costs, but to run costs.Equipment requires regular maintenance and parts replacement, and it is necessary to planning such running costs.
The main running costs are:
| 費用名 | 費用額 | 頻度 |
| 定期メンテナンス費 | 2～3万円 | 3～4年に一度 |
| パワーコンディショナーの交換費 | 約20万円 | 20年に一度 |
| 蓄電池の交換費 | 100万～150万円 | 10～15年に一度 |
If all payments overlap, the annual payment is up to 1.73 million yen.Because it is not a small amount, it is necessary to save money with the saved amount and power sales income.
It is difficult to earn by selling electricity
Solar power selling prices are declining year by year, for example, compared to the 2012 purchase price, making it difficult to earn money by selling power.In a clear number, from 2012 to 2020, the price selling price is about half of 42 yen to 21 yen per kWh.It is expected to be 11 yen from 2025 to 2027, and even if you start immediately, you will not be able to earn more than at the beginning of selling power.
However, electricity for housing continues to change in the 20 yen range, and there is even a trend.Therefore, it is more likely that those who will set up solar power will save money instead of earning power, but more likely to save money.
Power generation is susceptible to weather
Due to its nature, solar power is a weak point.On a sunny day, the ability is demonstrated, but on days when the sun does not appear, such as cloudy or rain, the amount of power generation decreases.In addition, not only the weather but also the temperature affects the amount of power generation, so there is a difference in power every season.
The specific impact of each season is as follows.
| 春 | 湿度が落ち着き日照時間も増えてきて、徐々に発電量が上がる |
| 梅雨 | およそ1ヶ月半の間は、曇りや雨の日が多く発電量が下がる |
| 夏 | 日照量が上がり、発電量が最も見込める季節 |
| 夏〜秋 | 梅雨や日照量が下がる秋口は、やや発電量が下がる |
| 冬 | 日照時間が少なくなる10月～2月程度までは、最も発電量が落込む |
In the rainy season and winter, the sunshine hours are particularly short, so it is expected that the weather will be greatly affected.Therefore, before installing, it is necessary to simulate sufficiently, such as whether it can be used by storing electricity even if the weather is affected.
If you want to install solar power, you will take insurance
Solar power is a risk of natural disasters, so it is recommended that you take out insurance before installation.If the panel will be skipped due to a typhoon, and if the nearby housing is damaged, the income of the power will also fly.
There are the following of solar power insurance:
| 企業総合保険 | 火災を含めた自然災害を補償する保険 |
| 動産総合保険 | 企業総合保険と似た条件で、災害があった場合にカバーする保険 |
| 休業損害補償保険 | 太陽光発電が事故で損傷した場合に損失を補償する保険 |
In this way, we are developing insurance that compensates for disasters and unexpected accidents.There are various other products for solar power generation, so we recommend that you consider both in case of emergency.
In the future, it is expensive to remove solar power
It must be remembered that solar power equipment has a lifespan, so if it does not continue, removal will be required.If you quit solar power, you will be charged for removing equipment and recycling solar panels.In addition, if the removal work is performed, we will ask the contractor who constructed, but if not, we will have a third -party organization referral and request removal.
Depending on the scale, the cost is about 100,000 yen, the disposal cost is about 50,000 yen, and the recycling cost of solar panels is 1,200 yen per sheet.
Looking at this is not cheap.However, if solar power equipment is discarded other than a determined method, illegal dumping may be imposed in imprisonment of 5 years or less or less than 10 million yen or both.Be sure to remove and dispose of it according to the prescribed method.

Solar power can be started with zero installation costs by leasing and shaving equipment in cooperation with business operators.If the installation cost of about 1.4 million yen is not required, solar power will be familiar and familiar.
In addition, it is possible to greatly reduce the burden with ZEH -related subsidies.Since all of the conditions and products are different, we recommend that you simulate and consider whether it meets your needs.When considering, compare multiple companies with reference to the outline introduced this time, and choose something you want to introduce.Please take this opportunity to aim for energy operation that saves solar power installation costs.
