Troubles that can occur at power plants during the winter season and how to address them.

Troubles that can occur at power plants during the winter season and how to address them.

The enemy of solar power generation in winter is snow! Prompt action can prevent the expansion of troubles and increase in losses.

We would like to introduce seasonal solar power generation troubles. There are two main types of solar power generation troubles caused by snowfall: one is that snow accumulates and blocks sunlight, leading to a decrease in power generation, and the other is that if too much snow accumulates, the panels or mounting structures may not be able to withstand the weight and could be damaged. The first measure against snow is proper installation, and if there are consecutive snowy days or a possibility of heavy snowfall, it is best to clear the snow. Our company not only provides installation services for solar power plants but also offers consistent maintenance services afterward, and we also provide O&M services that encompass maintenance and management. 【Examples of solar power generation troubles】 ■ Decrease in power generation ■ Accumulated snow may slide off and affect the lower parts ■ Panels may crack under excessive weight ■ Mounting structures may collapse under the weight ■ There is a possibility of secondary disasters affecting adjacent land *For more details, please refer to the related links or feel free to contact us.

Location where solar power generation can be installed: "carport"

Location where solar power generation can be installed: "carport"

Solar panels can be installed not only on the roof of a house but also in gardens and carports, etc. ... *The materials are from the booklet "Tell Me! Excavation Team!"

In recent years, with the spread of solar power generation, more people have been installing solar panels on top of their carports at home. It seems to be gaining popularity because, unlike gardens, it doesn't take up much space. The conditions for installation are: (1) There should be enough space for two cars, (2) The carport should not be shaded. Additionally, since the carport is lower than the house roof, (3) It is important that there are no tall buildings nearby. Recently, there has been an increase in customers installing solar panels on carports in areas such as Tochigi Prefecture, Ibaraki Prefecture in northern Kanto, and Chiba and Saitama Prefectures in the metropolitan area. Furthermore, when installing in conjunction with the house roof, even if there isn't much space for panels on the roof, the power generation from the carport can supplement and increase the overall power generation. ★ Right now, you can download the booklet "Basic Knowledge for Introducing Solar Power Generation Systems" for free. ★ ≪Contents Included≫ - What is a solar power generation system? / How solar power generation works - Types of solar panels and how to choose them - Power generation simulation - Annual forecast power generation amounts across the country - Installation examples - Benefits of having over 10 kW - Regarding selling electricity and more.

Location where solar power generation can be installed: "garden"

Solar panels can be installed not only on the roof of a house but also in gardens and carports, etc. ... *The materials are from the booklet "Tell Me! Excavation Team!"

In recent years, with the spread of solar power generation, it seems that more people are installing solar panels in their gardens at home, just like they do in their carports. Even in cases where the roof has a complex shape or faces north, making it impossible to install solar panels, it may still be possible to install them in the garden. Additionally, for those who are concerned about drilling holes in an aging roof, installing a solar power generation system in the garden allows for implementation without worrying about the roof. Unlike roofs that are installed at high locations, gardens offer the advantage of easier maintenance. The installation work can also be done with simpler construction than on a roof. Since installation in the garden can be done with relatively simple work, costs tend to be lower. ★ Right now, you can download the booklet "Basic Knowledge for Introducing Solar Power Generation Systems" for free. ★ ≪Contents≫ - What is a solar power generation system? / How solar power generation works - Types of solar panels and how to choose them - Power generation simulation - Annual forecasted power generation across the country - Installation examples - Benefits of exceeding 10 kW - Regarding selling electricity and more.

Points to consider when installing solar panels

Points to consider when installing solar panels

Points to note about solar power generation systems that have various benefits ... *The material is from the booklet "Tell Me! Excavation Team!"

Impact on the Roof The roof of a house is not originally designed for the installation of solar panels. In typical construction methods, holes are drilled into the roof to install brackets that secure the solar panels, which can affect waterproofing. It is important to choose a reliable and trustworthy contractor who provides sufficient explanations, and to thoroughly check the construction details, aftercare, and warranty information. Tax on Electricity Sales Income Income from selling electricity generated by solar power is not fully exempt from taxation, and there may be cases where it is subject to tax. If your total income from sources other than salary exceeds 200,000 yen, you will need to file a tax return. Regions Requiring Caution for Installation While solar power generation systems are widely adopted across the country, there are regions where caution is necessary for installation. ★Currently, you can download the booklet "Basic Knowledge for Introducing Solar Power Generation Systems" for free.★ ≪Contents Included≫ - What is a solar power generation system? / How solar power generation works - Types of solar panels and how to choose them - Power generation simulation - Annual forecasted power generation amounts across the country - Installation examples - Benefits of exceeding 10 kW - Regarding electricity sales and more.

Area required for installing solar panels

Area required for installing solar panels

Introduction to the area required for installing a solar power generation system ... *The material is from the booklet "Tell Me! Excavation Team!"

When installing a solar power generation system, a larger roof allows for the installation of more panels. If you have already determined the desired generation capacity before installation and know the area of the installation site, you can calculate it in advance. For example, if you know the installable area (m²), you can find the installation capacity (kW) by dividing the installation area by 10. Example: If you have a land or roof area of 100m², you can install 10kW (100 ÷ 10 = 10). Next, if you have a specific desired capacity (kW), you can determine the necessary area by multiplying the installation capacity by 10. Example: If you want to install a 200kW solar power generation system, you will need 2000m² of land (200 × 10 = 2000m²). ★ Right now, you can download the booklet "Basic Knowledge for Introducing Solar Power Generation Systems" for free. ★ ≪Contents≫ - What is a solar power generation system? / How solar power generation works - Types of solar power panels and how to choose them - Power generation simulation - Annual forecasted power generation amounts across the country - Installation examples - Benefits of exceeding 10kW - Regarding selling electricity and more.

Cost of installing a solar power generation system

Cost of installing a solar power generation system

Regarding the costs associated with the installation of solar power generation systems, as well as the prices and performance of various manufacturers... *The materials will be from the booklet "Tell Me! Excavation Team!"

Solar power generation does not incur fuel costs like gasoline, so the costs involved are primarily for solar panels, installation work, and maintenance. When solar panels were first developed, they were considered a very expensive product category, but it is evident that prices have been decreasing year by year. However, this decline has not been rapid; rather, it has been a gradual decrease. If the installation timing is delayed to reduce initial costs, and the feed-in tariff decreases proportionally, it will take longer to recover the initial installation costs through sales revenue. Considering these points, the timing of installation should not be based on the thought of "new electronic products like computers and TVs are being released, but since they are expensive now, I will wait until the price drops," but rather, the timing should depend on the customer's plans. ★Currently, you can download the booklet "Basic Knowledge for Introducing Solar Power Systems" for free.★ ≪Contents≫ - What is a solar power generation system? / How solar power generation works - Types of solar panels and how to choose them - Power generation simulation - Annual forecasted power generation in various regions - Installation examples - Benefits of exceeding 10 kW - Regarding selling electricity and more.
