Self-consumption solar power generation

Self-consumption solar power generation

Installation is recommended for businesses and facilities with high electricity usage during the day! Transition to self-consumption type after the end of the feed-in tariff (FIT).

Self-consumption type power generation refers to the method of installing renewable energy generation systems, such as solar power generation, on unused land like the roofs or parking lots of facilities, and using the electricity generated there at nearby consumption sites (such as offices, factories, and facilities). By implementing self-consumption, which has already become common in households, companies can expect to reduce the soaring electricity costs. Additionally, with the declaration of carbon neutrality, companies are increasingly required to engage in initiatives to reduce CO2 emissions, and adopting self-consumption type solar power generation can contribute to corporate evaluation. 【Features】 ■ Reduces electricity usage, thereby lowering electricity charges and renewable energy surcharges ■ Provides power supply to various electrical devices in the event of a power outage ■ Avoids various troubles caused by sudden power interruptions ■ A method of power generation that emits less carbon dioxide compared to thermal power generation ■ Can be utilized as J-Credits *For more details, please refer to the related links or feel free to contact us.

Is it wiser to make than to buy? Reduce electricity costs with self-consumption!

Is it wiser to make than to buy? Reduce electricity costs with self-consumption!

It's easy to adjust the scale based on the size and shape of the installation area! An introduction to solar power in the column.

Self-consumption refers to the style of consuming electricity generated without selling it. Large-scale solar power generation facilities are built with the aim of selling all the electricity generated (selling all without using any), but due to the decreasing feed-in tariffs year by year, it has become increasingly difficult to make a profit. This is where self-consumption is gaining attention. In this column, we discuss renewable energy "solar power generation," which is easy to introduce as a self-consumption model. [Content Overview (Excerpt)] ■ A shift towards making and using rather than buying ■ What are the benefits of self-consumption? ■ Is it possible to not benefit from self-consumption? ■ Are there subsidies for self-consumption? ■ Inquiries regarding full self-consumption *For detailed content of the column, please refer to the related links. For more information, feel free to contact us.
