Incorrect Solar Panel Output in Console

Turning on a power-consuming block causes solar panel output reported in the console to be incorrect. The reported value is lower than expected, with the difference equal to the amount of power consumed by the block that was turned on. The correct value is shown when any power-consuming block is turned off or the grid's total generated power changes by turning on another power generation block or the sun moves.

Steps to reproduce:

1. Create a world with sun rotation disabled (so sun motion doesn't cause the solar panel output to change)
   
2. Place a solar panel and wait for output to stabilize
   
3. Place a battery
4. Place a beacon (or other power-consuming block)
5. Turn the beacon off and back on. Note power consumption rate reported in the console
6. Look at power output reported in the solar panel console details. It is different by the rate observed in the previous step.
7. Change the beacon range so power consumption changes.
8. Repeat steps 5 and 6 and note that the solar panel output is incorrect by the new consumption rate of the beacon.
9. Look at the battery input value and note that it is correct (showing the 'Max Output' value of the solar panel rather than the incorrect 'Current Output'.)
10. Turn off the beacon, or toggle solar panel off/on, or toggle entire grid off/on (slowly) and note that the Current Output of the solar panel is now reported correctly. If sun rotation is turned back on, the movement of the sun will also update the solar panel's Current Output value to report correctly.
    

A similar effect can be observed by sitting in a control seat and quickly toggling the grid power off/on. Reported solar panel Current Output will be incorrectly low by 3kW, which I assume is the amount of power the player suit will consume. Turning grid power off and waiting a second or so before turning it back on will avoid the bug.
