"Unused land" where solar power generation can be installed.

Solar panels can be installed not only on the roofs of houses but also on unused land, etc. ... *The material is from the booklet "Tell Me! Excavation Team!"

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.

Benefits of introducing solar power generation systems to apartments and condominiums.

About twice that of a typical residence! Regarding the introduction of solar power systems in apartments and condominiums ... *The materials will be from the booklet "Tell Me! Excavation Team!"

○ High-output systems can be introduced! The average solar power generation system that can be installed in typical homes is about 4kW, but in the case of apartments or condominiums, a larger roof can be utilized, allowing for systems of about 7-8kW, which is approximately double. ○ Revenue from selling electricity can be expected! When a solar power generation system is installed with shared interconnection, all electricity generated is connected to the owner's power conditioner, and all surplus power, except for the electricity used in common facilities, can be sold. ○ Tenants are likely to choose and stay long-term! When installed with individual interconnection, there are benefits for tenants. ○ Can be used as an emergency power source! Power can be secured even during power outages. ○ There are tax benefits! The acquisition cost of the solar power generation system can be fully depreciated in the first year. ★ Right now, you can download the booklet "Basic Knowledge of Solar Power Generation System Installation" for free. ★ ≪Contents included≫ - What is a solar power generation system? / How solar power generation works - Types of solar panels and how to choose - Power generation simulation - Annual forecasted power generation amounts across the country - Installation examples - Benefits of having over 10kW - Regarding selling electricity and more.

Benefits of introducing a solar power generation system for outdoor use!

Achieve early recovery of initial costs and electricity sales revenue with a low-cost, high-output system! ... *The materials are from the booklet "Tell Me! Excavation Team!"

We use high-output 190W monocrystalline panels, and by reducing material costs and keeping panel prices as low as possible, we can achieve a low-cost system that shortens the payback period for installation costs. The mounting structure uses single pipes, making installation very easy while ensuring strong wind resistance. The purchase price for solar power systems fluctuates annually, but the purchase price for the year of installation is fixed for 20 years. With the current purchase price, it is possible to quickly recover the initial investment made at the time of installation. After recovering the initial costs, 100% of the electricity generated will be income from selling power, making it very advantageous to implement the system now while early cost recovery is possible! ★ Right now, you can download the booklet "Basic Knowledge for Introducing Solar Power Systems" for free. ★ ≪Contents Included≫ - What is a solar power system? / How solar power 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 10kW - Regarding selling power and more.

[Case Study of Self-Consumption PPA] Reduced Electricity Costs! No Generation Loss with Monitoring

Bandai Shoten Nagano is a case study of the introduction of Aozora Electric's PPA solar power generation, which is generating more electricity than expected and helping to reduce electricity costs.

We would like to introduce a case of the introduction of Aozora Electric's PPA solar power generation at Bandai Bookstore Nagano. The Nagano store operates year-round without holidays, and the annual electricity costs for lighting and air conditioning were very high. Since the store had already implemented LED lighting, they decided to introduce Aozora Electric as another project to reduce electricity costs. The ability of solar power generation to reduce CO2 emissions and its consideration for the global environment were also key factors in their decision. 【Case Study】 ■ Implementation Date: February 2019 ■ Location: Nagano City, Nagano Prefecture *For more details about the case, please visit our company website.

[Case Study] Nagano International Country Club

Introduction of examples where solar power is used to operate equipment within golf courses.

We spoke with Nagano International Country Club about the purpose and effects of introducing solar power generation. Due to the aging of the power lines, it became necessary to replace and renovate them, which would incur high costs. They were exploring better alternatives at that time and learned that off-grid systems could provide electricity at a lower cost, leading to the decision to implement it. This has resulted in significant cost savings. Additionally, they find the combination of solar power generation and storage batteries to be a very attractive system that considers the natural environment. [Case Summary (Partial)] ■Challenges - The aging of power lines necessitated replacement and renovation, leading to high costs. ■Results - Significant cost savings were achieved. *For more details, please refer to the PDF document or feel free to contact us.
