Even if the roof shape of a detached house is not suitable for installing a solar power generation system, it is possible to introduce a solar power generation system of 2kW to 4kW by utilizing the roof area of a carport. If a solar power generation system has already been installed in the house, introducing a solar power generation system on the carport can achieve a high output that would be difficult with just the residential portion. If the amount of electricity generated can be increased, it is expected that surplus electricity will also increase, leading to potential economic benefits from selling electricity back to the power company. Although it may be thought that carports are not eligible, subsidies from the government and other sources can also be applied to solar power generation systems installed on carports, helping to reduce initial costs. ★ 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 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.

Solar power generation does not incur fuel costs like gasoline, so the costs involved are primarily the price of solar panels, installation costs, and maintenance expenses. When solar panels were first developed, they were categorized as very expensive products, but it is evident that their 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 in proportion, it will take longer to recover the initial installation costs through sales revenue. Considering these points, the decision on when to install should not be based on the thought of "new electronic products like computers and TVs are released, but since they are expensive now, I will wait for prices to drop before purchasing." Instead, the timing of installation ultimately depends on the customer's plans. ★ Right now, you can download the booklet "Basic Knowledge for Introducing Solar Power 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 across the country - Installation examples - Benefits of having more than 10 kW - Regarding selling electricity and more.

When installing a solar power generation system, a larger roof allows for more panels to be installed. 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 100 ÷ 10 = 10kW. Next, if you have determined the desired capacity (kW), you can find the required area by multiplying the installation capacity by 10. Example: If you want to install a 200kW solar power generation system, you will need 200 × 10 = 2000m² of land. ★ 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 power panels and how to choose them - Power generation simulation - Annual forecasted power generation amounts across the country - Installation examples - Benefits of having more than 10kW - Regarding selling electricity and more.

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 in the roof to install brackets to 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. Taxes on Electricity Sales Income Income from selling electricity generated by solar power is subject to taxation, although not on the full amount. 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. ★ 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 power generation forecasts for various regions - Installation examples - Benefits of exceeding 10 kW - Regarding electricity sales and more.

Points to Consider When Choosing Solar Panels (1) Price Price is often compared not by how low it is, but by the cost per watt. This is to assess the cost performance relative to the power generation capability. (2) Conversion Efficiency and High Self-Generation Amount Conversion efficiency is calculated as [Nominal Maximum Output of the Module (W)] ÷ [Module Area (m²) × 1000 W/m²]. This represents the power generation amount per unit area. (3) Actual Power Generation Some manufacturers focus on actual power generation, ensuring that the output does not decrease even in shadowy or cloudy conditions. ★ 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 power generation forecasts across the country - Installation examples - Benefits of exceeding 10 kW - Regarding selling electricity and more.

Solar power generation systems can be installed not only on rooftops but also on idle land. "I own land, but it's unused and lying dormant." "There is unused land such as idle land, fallow land, wasteland, vacant lots, and forests." For those with such idle land, ground-mounted solar power generation is an option for land utilization. The larger the land, the more solar panels can be installed, and since installations are mostly over 10 kW, they can be purchased by power companies at a fixed price for 20 years. As a result, the mega solar business, which generates significant profits from selling electricity, is becoming increasingly popular. It might also be a good opportunity to reconsider land currently used for other purposes, such as material storage or parking lots. ★ 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 power generation forecasts for various regions - Installation examples - Benefits of having over 10 kW - Regarding selling electricity and more.

In recent years, with the spread of solar power generation, it seems that more people are installing solar panels in their gardens, just like in their home carports. Even when the roof has a complex shape or faces north, making it impossible to install solar panels, there are cases where installation is possible in the garden. Additionally, for those who may feel anxious about making holes in an aging roof, installing in the garden allows for the introduction of a solar power generation system without worrying about the roof. Unlike roofs that are installed at high locations, there is the advantage of easier maintenance in the garden. The installation work can also be done with simpler construction than on the roof. Since the work in the garden is relatively straightforward, there tends to be a reduction in costs. ★ 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 forecasted power generation amounts across the country - Installation examples - Benefits of exceeding 10 kW - Regarding selling electricity and more.

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 space. The conditions for installation are: (1) There must 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 installed in conjunction with the roof of a house, even if there isn't much space for panels on the roof, the power generation from the carport can supplement and increase the total power output. ★ 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.
