We will introduce frequently asked questions about self-consumption solar power generation. The capacity of the panels that can be placed on the roof is estimated as "area (m2) × 0.1 kW" when laid flat on the roof. Additionally, if you have a contract to receive surplus electricity for free, any unused electricity will flow to the power company through the power lines. By setting up a storage battery, you can store excess electricity, allowing you to use it efficiently. We will also answer other common questions such as, "Is it necessary to notify the power company even if I don't sell electricity?" and "Will there be a power outage during construction?" *For more details, please refer to the PDF materials or feel free to contact us.

Factors contributing to the rise in electricity costs include the increase in levies due to the introduction of the fixed-price purchase system and price hikes associated with the consumption tax increase. Including factors such as the rise in renewable energy levies, electricity costs are expected to continue to increase in the future. While the selling price of electricity decreases year by year, the unit price of electricity for corporations is on the rise, making self-consumption solar power more economically advantageous than purchasing electricity. 【External factors contributing to the rise in electricity costs】 ■ Increase in levies due to the introduction of the fixed-price purchase system ■ Increased reliance on thermal power generation due to the suspension of nuclear power plants ■ Price hikes associated with the consumption tax increase *For more details, please refer to the PDF document or feel free to contact us.

Self-consumption solar power generation directly reduces electricity costs as all generated electricity is consumed on-site. In addition, there are various benefits such as disaster preparedness, heat insulation effects, and tax-saving measures. Furthermore, the design of self-consumption solar power generation can be categorized into three types: "excess generation type," "minimum demand type," and "output control type." The "minimum demand type" is recommended for companies with limited installation space or commercial facilities and warehouses with little fluctuation in annual electricity usage. 【Benefits】 ■ Reduction in electricity costs ■ Disaster preparedness ■ Heat insulation effects ■ Tax-saving measures ■ Installation subsidies ■ Factory location law measures *For more details, please refer to the PDF document or feel free to contact us.

• Roof and gutter construction

The sludge generated from our factory contained a lot of moisture, which increased its volume, making the waste disposal costs quite high and problematic for us. In an effort to reduce these costs, we searched for methods to decrease the volume and mass of the sludge. A vacuum dryer creates a state close to a perfect vacuum, and when we input the thick sludge containing a lot of moisture, the moisture evaporates from the sludge even at low temperatures. The thick sludge changes its state to a powder form, reducing its volume. We were able to lower the waste disposal costs for the sludge, and the fuel required for drying was also less than that of other devices, which was a decisive factor. 【Overview】 ■ Equipment: Sludge treatment equipment ■ Industry: Plating factory ■ Effect: Environmental improvement *For more details, please refer to the PDF document or feel free to contact us.

• Water Treatment

Our factory had been struggling with pest bird damage for some time. They built nests inside the factory, frequently leaving droppings in the parking lot, and we were particularly worried about the possibility of droppings on products before they were shipped after packaging. We tried various measures against pest birds, such as netting and spikes, but saw no effect and were almost resigned to the situation. After researching, we discovered a company that guarantees the effectiveness of their pest bird measures for three years. They seemed to use a gel made from plant oils (herbal extracts) and capsaicin (the spicy component of chili peppers). In any case, we decided to buy their confidence in the three-year unconditional guarantee and give it a try. As a result, not a single pest bird that had been so persistently residing there was left. The effect was noticeable by the evening after the treatment was done in the morning.

The building itself is old, and significant deterioration had progressed. Nevertheless, in order to keep it clean for a long time, we had been conducting wall cleaning (high-pressure washing) as an annual event for our employees. However, seeing our factory getting dirty every year made me think, "It seems somewhat silly to clean it every year." This glass coating is a special type of glass that remains in liquid form at room temperature and, when dried, has properties indistinguishable from solid glass. Once applied to the building, it becomes covered with a glass film. Buildings covered with this glass film (including outdoor-installed cubicles) gain various protective functions such as dirt resistance, corrosion resistance, rust resistance, salt damage resistance, and chemical resistance. With this technology, the building has become almost completely clean, so one of our annual events (building cleaning) has been eliminated. It feels a bit lonely, but the employees seem very pleased.

At our factory, we process automotive parts. The wastewater generated during manufacturing contains oil components such as machining oil, which we used to have disposed of by a waste disposal company. With strict cost reduction demands from our customers, we wanted to reduce the costs associated with wastewater treatment. We learned that an oil-water separation system could separate (remove) the oil and sludge contained in the wastewater to nearly zero, so we first installed a demo unit in-house to verify its effectiveness. As a result of the verification, it was found that we could remove oil components down to about 1/100. The separated oil components are reused after removing waste, and any excess can be sold, resulting in significant cost savings. 【Overview】 ■ Equipment: Wastewater treatment equipment ■ Industry: Metal processing factory ■ Effect: Environmental improvement *For more details, please refer to the PDF document or feel free to contact us.

We introduced it due to the update of an old boiler. Originally, our factory had a high boiler operating rate and used a lot of fuel gas, which increased costs. Therefore, we installed a demo unit in-house to measure its effectiveness over a month. As a result of the test, we found that our gas usage was reduced by about 5%. The return on investment was quick, so we proceeded with the installation with confidence. The gas costs, which had been a long-standing issue, decreased.

Steam was leaking along with the drain from the steam trap. Even if we replaced the trap immediately, it would break like a consumable, leaving us frustrated. The energy-saving trap we introduced this time reportedly has no moving parts. By preventing steam leakage, we achieved a 42.4% cost reduction. Made of stainless steel, it has high durability and a low replacement frequency, and its structure allows for easy maintenance, solving the issues of conventional steam traps.

A large amount of drain was generated, and energy loss became a challenge. Upon investigating the cause, it was found that the steam generated from the regular boiler produced wet steam with low dryness, resulting in a significant amount of drain in the piping. Therefore, a cyclone-type steam reforming device was introduced. The dry steam sent to the secondary steam header is less likely to turn into drain during transportation to the factory, allowing it to be supplied to steam-using equipment and machinery in very good condition. After the introduction, we successfully achieved a cost reduction of 18% (over 10,000,000 yen annually).

I was recommended energy-saving hydraulic systems by a competitor, and I found it very interesting for our factory, which uses a lot of hydraulic equipment (motors). Hydraulic accumulators function like batteries, allowing the hydraulic unit to store the pressure exerted on the hydraulic fluid when operating at full capacity. When releasing the stored pressure, it suppresses the excessive operation of the hydraulic motors. After implementation, we successfully reduced power consumption by approximately 95%. 【Overview】 ■ Equipment: Hydraulic motors ■ Industry: Metal processing factory ■ Energy-saving rate: 95% *For more details, please refer to the PDF document or feel free to contact us.

I understand well that reducing energy consumption with small motors in machine tools can lead to cost savings, but since it's a running machine, it cannot be stopped. I also considered inverter control, but gave up due to the enormous initial costs. However, this motor harmonic countermeasure allows for energy savings without having to stop the machine (motor). Additionally, since it is installed in parallel to the power transformer, it provides energy-saving benefits to all three-phase induction motors (200V or 400V) connected to the transformer. After implementation, we were able to reduce the electricity consumption from 290,000 kWh/month to 252,000 kWh/month, achieving approximately 13% energy savings.

Within the company, we were looking for ways to further reduce costs. The newly implemented quantity control system features more precise control compared to conventional methods. It continuously monitors pressure and can accurately start and stop compressors with the necessary capacity as needed. Additionally, it is possible to analyze and automatically calculate data collected from pressure monitoring sensors, allowing for load predictions. Even if the lower limit of the original pressure is set as low as possible, there is no risk of pressure shortages causing the line to stop. After implementation, we were able to reduce costs by approximately 35%. 【Overview】 ■ Equipment: Compressor ■ Industry: Resin processing factory ■ Energy-saving rate: 35% *For more details, please refer to the PDF document or feel free to contact us.

• Garbage disposal, central dust collection, laundry, compressor

In the product manufacturing process, there are many steps such as water removal blow and dust removal blow, and air blowing is constantly in a state of being wasted. The enhanced discharge intermittent blow system is attractive because it can reduce unnecessary air consumption by switching from continuous blow to intermittent operation. Additionally, since air repeatedly collides with the target object, the blow effect is improved, and work efficiency (blow time) has also increased. Furthermore, it was very easy to implement without the need for electrical work. In fact, we were able to reduce the annual air consumption from 53,637 Nm3 to 26,819 Nm3, successfully achieving approximately 50% energy savings.

• Garbage disposal, central dust collection, laundry, compressor

I was progressing with the update of the compressor, but I was troubled by the electrical work costs associated with the update being higher than I had imagined. After considering various methods, the final conclusion was to introduce a special starting device. This starting device allows us to suppress the starting current of the compressor, enabling us to use the existing wiring and breakers, thus eliminating unnecessary electrical work costs. The decisive factor for the introduction was simply that the estimated cost of the digital starting device (including installation) was cheaper than the estimate for the electrical work. Additionally, the load on the motor, belt, gears, etc., is reduced, which can extend the lifespan of the compressor.

• Garbage disposal, central dust collection, laundry, compressor

We perform cleaning of bed sheets and bath towels used in hotels, and during the summer, the working environment was particularly harsh due to waste heat from large dryers. The workspace inside the factory is very spacious, making it nearly impossible to cool the entire area with air conditioning. While researching various options, I came across a technology called well water spot coolers. This system cleverly utilizes well water, which maintains a constant temperature (15-17°C) throughout the year, to create cool air and spot cool the workspace. We were already using a lot of well water, which helped keep running costs low. Since it doesn't use a compressor, the power consumption is limited to just the fan and pump, resulting in lower electricity costs. It was also beneficial that we were able to experience a simple demo unit before implementation, allowing us to proceed with confidence. 【Overview】 ■ Equipment: Air conditioning ■ Industry: Cleaning factory ■ Energy saving rate: 90% *For more details, please refer to the PDF document or feel free to contact us.

In the factory, there is a rice cooker for cooking rice. To minimize the escape of indoor heat, forced ventilation was implemented. However, the balance between intake and exhaust was not well managed, resulting in a negative pressure state inside the cooking room. When negative pressure occurs, it becomes easier for garbage, dust, and insects from outside to enter, making it difficult to address the issue. Therefore, a vapor heat utilization air supply system was introduced. This system utilizes only vapor heat to cool and supply fresh outside air. In practice, during the summer, outside air at 36°C was cooled down to about 27°C before being supplied indoors. This system does not have a compressor, allowing it to operate with approximately 70% lower power consumption compared to conventional air supply units, which is also an attractive feature. Furthermore, since it does not use refrigerants, there is no need for CFC inspections, which is very helpful. 【Overview】 ■ Equipment: Air conditioning ■ Industry: Metal processing factory ■ Energy-saving rate: 70% *For more details, please refer to the PDF document or feel free to contact us.

The air conditioner used in the factory was old and had hardly been cleaned, so its efficiency was deteriorating rapidly. When I opened the air conditioning unit to clean it and improve its efficiency, I found that dirt and dust were caked onto the heat exchanger. As I researched further, I learned about the existence of a robot cleaning machine specifically for air conditioners. It can carefully high-pressure wash each aluminum fin of the heat exchanger down to the millimeter, effectively removing dirt that conventional hand washing could not. After actually using it, the airflow improved from 11.73 m³/min to 14.92 m³/min, a recovery of 24%. Consequently, power consumption was also reduced by 4%.

The lighting has already been switched to high-efficiency lighting, and it has certainly become energy-saving. So now, I was looking for something else that could be done with other equipment. In the process, I found an interesting technology related to the air conditioning equipment, which incurs high electricity costs in our factory. The air conditioning net simply requires being secured with wire at the ventilation parts of the outdoor and indoor units to achieve energy savings. Since we could conduct a free test in our company, we verified the effects in three rooms. As a result, energy-saving effects of 19%, 25%, and 40% were observed in all rooms. No construction is required, and installation is easy. Additionally, being able to demonstrate the effects before implementation was the deciding factor for adoption.

There were temperature variations indoors, with the window side being hot in summer and the floor being cold in winter. Even when changing the set temperature, it would either become too cold or too warm in localized areas, making it very difficult to adjust the indoor temperature. I found a solution that utilizes an existing air conditioning system with a circulation fan to eliminate the temperature variations indoors. I quickly conducted an effectiveness test in our office during the extremely cold winter, and in the room where the circulation fan was installed, there was a noticeable effect (elimination of temperature variations between the top and bottom). Additionally, I found that there was no noise at all, allowing us to maintain a comfortable working environment. 【Overview】 ■ Equipment: Air conditioning ■ Industry: Resin processing factory ■ Environmental improvement *For more details, please refer to the PDF document or feel free to contact us.

We have already introduced high-efficiency lighting and were considering the implementation of demand control to further reduce electricity costs. The air conditioning intermittent operation system allows for timer-based energy-saving system control, enabling management without changing the environment of the workspace, which was the deciding factor for its introduction as it does not affect product quality. In fact, we were able to reduce the basic fee by 510,000 yen per year and the usage fee by up to 1,000,000 yen per year while keeping the temperature within the set range inside the refrigeration and freezing equipment. 【Overview】 ■ Equipment: Air conditioning ■ Industry: Food processing factory ■ Energy saving rate: 43% *For more details, please refer to the PDF document or feel free to contact us.

The domestic LED lights with human sensors can prevent unnecessary power consumption with the sensors, making them ideal lighting for factories. Especially during nighttime operations, only the necessary areas (the areas in use) are lit, which allows for significant electricity cost savings, and this was the deciding factor for the introduction. Previously, the electricity cost for lighting alone was 910,000 yen per year, but after the introduction, we were able to reduce it to 170,000 yen per year. 【Overview】 ■ Equipment: Lighting ■ Industry: Seafood processing factory ■ Energy-saving rate: 81% *For more details, please refer to the PDF document or feel free to contact us.

• Other lighting fixtures

For a long time, we were searching for a way to keep costs down by not switching to high-efficiency lighting and continuing to use existing fixtures and bulbs. The solution we found was to switch the ballast to a high-efficiency one. Without changing the work environment, we were able to reduce running costs by 43% (measured value). Additionally, the energy-saving ballast can mitigate the excessive current during ON/OFF cycles, which causes filament degradation, allowing existing bulbs to have a longer lifespan and significantly reducing costs associated with consumables. 【Overview】 ■ Equipment: Lighting ■ Industry: Printing Factory ■ Energy Saving Rate: 43% *For more details, please refer to the PDF document or feel free to contact us.

Before the introduction, I wanted to know if it would really be effective in our warehouse, so I had the operating rate measured with a measuring device. As a result of the measurement, it was found that the operating rate was about 30% (if the warehouse operates for 10 hours a day, the actual working time is about 3 hours a day). When I calculated how much energy could actually be saved based on the measured data, it was said that a reduction of 80% could be achieved, so we promptly implemented it.

Previously, we used mercury lamps, and there were concerns that the warehouse was dark, which might be reducing work efficiency. However, with LED lights, while the area directly under the light is bright and glaring, there were worries that it could be too dazzling and reflect off products, potentially decreasing work efficiency, which made us hesitant to implement them. We decided to introduce "electrode-less lamps" because they spread light more broadly compared to LEDs, illuminating the entire area without glare. We have successfully reduced power consumption by 76% before and after the introduction without lowering work efficiency. 【Overview】 ■ Equipment: Lighting ■ Industry: Logistics Warehouse ■ Energy Saving Rate: 76% *For more details, please refer to the PDF document or feel free to contact us.
