But, is solar worth it?

Yes. Since installing solar I've saved ¥122,376 in electricity costs.

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

Nov 15 ~ Dec 14

I consumed 201.62kWh and generated 142.42kWh.

This would have cost me ¥8,267 without solar.

My actual cost was ¥2,516.

I saved ¥5,751 with generation and earned ¥542 for a total savings of ¥6,293
