The GST on solar products has been increased from 5% to 12%. From 1st October onwards all solar products or solar panel systems will attract a GST of 12%.
Therefore, in this article, I’ve explained the billing pattern of the on-grid solar panel system and how the tax structure should be on the invoice.
Billing Pattern for Hybrid Solar Panel System
Hybrid Systems will have the same taxation as On-Grid systems. However, if we opt for individual item billing patterns, need to bill the battery at 18% and the description to be “Batteries for Solar system”.
Recommendation: Most of the houses are already having normal inverters for their critical load, so it’s better to go with a simple On-Grid solar system.
The system will be simple, less costly, less complicated and less maintenance, and ultimately you will save your electricity bill, resulting in faster payback.
There are broadly 2 types and each has 2 subtypes.
- Total System Billing
- Intra-State Billing
- Inter-State Billing
- Each Product Billing
- Intra State Billing
- Inter-State Billing
