The unit price of residential solar panels per kilowatt is decreasing year by year.
Solar power generation systems account for half of the kW unit price.
The solar module is the centerpiece.
We reduce the cost of introducing solar panel systems,
To make it more comfortable, safe and affordable,
We are installing solar panels using reused panels in Fukui Prefecture and other prefectures.

Breakdown of solar power generation system costs (new construction)
Approximate costs for residential solar panel installation (kw unit price)
・Solar panels 140,000 yen
・Frame, cable, power conditioner, etc. 55,000 yen
・Construction cost: 65,000 yen
・Other application fees, etc. 5,000 yen
The proportion of solar panels (modules) is approximately 40-50%.
How can I reduce the installation price of solar panels?
As shown in the breakdown above, the main solar panel of the solar power generation system is
We have significantly increased the kW unit price.
At our company, by constructing reused panels and unused (surplus inventory) panels,
Solar panels can be installed at significantly lower costs.
We handle everything from purchasing solar panels to in-house transportation, sorting, inspection and cleaning, and sales.
We install panels that give the owner peace of mind.
How to inspect and clean reused solar panels?
When you hear about reusable panels, you may have various questions about them, such as whether there is a warranty, inspection, and cleaning.
At our company, modules with an output value of 80% or less, which is our standard value, are disposed of.
Module inspection and cleaning will be carried out at our warehouse.
Each piece is carefully finished.
The applicable years of solar cell modules are:
It is said that it can generate electricity for 30 to 50 years or more, and it is said that it will generate electricity for nearly half a century.

Appropriate power generation simulation and prediction of equipment cost recovery
Since around 2017, the phenomenon of "grid parity" has been occurring, where the unit price of electricity sold is lower than the unit price of electricity purchased.
From now on, we will use electricity at home without selling it. `Self-consumption' will be a good deal.
* Surplus electricity can be sold using storage batteries or at a purchase price of 16 yen (FY2024)
Until now, we have been providing simulations of power generation x electricity sales price, but
We will propose the appropriate panel, power conditioner, and storage battery capacity based on your electricity usage situation.
Trying to recover storage battery costs from electricity bills
It will take about 20 years.
However, it will only be available when purchased at a reasonable price.
Please be careful about same-day contracts, which is a precaution when it comes to door-to-door sales.
