What you need to consider here is the cost of capital and the time to paying off the original investment.
For solar setups where you have excess energy during the day but mining is not profitable from the grid at night, the strategy is to get lower efficiency miners like S19s for cheap so that they pay off earlier. Having new generation models like an S21 or future S23 for running only half the time is probably a bad investment.
If you give more details on the situation we might come up with some ideas. But for your current question, mining half of the time gives you half of the rewards, half of the electricity consumption and full hardware depreciation/opportunity cost.
Yes, it will be an off-grid solar setup with batteries that keep the miner running during the night.
The electricity produced in June is about 6 times more than the electricity produced in December. So, there are two extremes:
A. Miner that is powerful (and expensive) enough to utilize the June energy. It will work on/off during the winter, waiting for the batteries to be charged. A downside is that money have been spent for a miner which is not utilized 100%, is not working 24/7/365.
B. Get a less powerful miner (cheaper) that can work non-stop even in December (100% utilization all through the year). Then there will be an excess energy in the summer. So, a downside is that money have been spent for solar panels which are not utilized 100% through the year (their energy is wasted in the summer, or at least not used for mining).

How much is the electricity cost from the grid approximately?
Ideas:
- Sell excess energy back to the grid. The electricity company might offer you a “virtual battery” where they keep a balance of excess power and let you consume a fraction of it at night or during other months. You can still install batteries for the day/night balancing and use this resource only for moving energy from summer to winter.
- Have an hybrid approach with some efficient miners for constant use and some less efficient ones for peaks during daylight and summer.
- Tweak the miners frequency to underclock them for slightly better efficiency and adapting to the solar production dynamically.
