Other companies’ plans often involve purchasing electricity generated by solar panels from the construction company (PPA provider) at a discounted rate, which means you still incur monthly electricity charges for the generated power. This can be more expensive in the long run and may not fully maximize electricity bill reductions. In contrast, Ohgiya Electric Industry recommends outright purchase, so all generated electricity belongs to you, allowing for maximum electricity cost reduction.

Depending on the conditions, it’s possible to reduce electricity costs by up to 20%. You can also see the specific reduction amount with a simulation.
