But, is solar worth it?

Yes. Since installing solar I've saved ¥265,018 in electricity costs.

Here's a breakdown for each billing period since my installation.

Jul 15 ~ Aug 14

I consumed 61.04kWh and generated 41.24kWh.

This would have cost me ¥1,686 without solar.

My actual cost was ¥762.

I saved ¥923 with generation and earned ¥132 for a total savings of ¥1,056
