There are several types of STES technology, covering a range of applications from single small buildings to community district heating networks. Generally, efficiency increases and the specific construction cost decreases with size. UTES (underground thermal energy storage), in which the storage medium may be geological strata ranging from earth or sand to solid bedrock, or aquifers. UTES technologies include: [pdf]

A group of Swiss researchers claim to have come up with a process that stores heat captured during summer for easy, flick-of-a-switch use in winter, with the added benefit that the captured energy can be physically transported anywhere it may be needed.
Funding to research thermal energy storage that could cut bills and boost renewables. New technology that could store heat for days or even months, helping the shift towards net zero, is the focus of a new project involving the Active Building Centre Research Programme, led by Swansea University, which has just been awarded funding of £146,000.
Seasonal thermal energy storage (STES), also known as inter-seasonal thermal energy storage, is the storage of heat or cold for periods of up to several months. The thermal energy can be collected whenever it is available and be used whenever needed, such as in the opposing season.
Warm-temperature seasonal heat stores can be created using borehole fields to store surplus heat captured in summer to actively raise the temperature of large thermal banks of soil so that heat can be extracted more easily (and more cheaply) in winter.

How do you turn on your solar panels?Step 1: Find your breaker box and turn on the solar breaker. Electrical panels or breaker boxes are typically found in utility spaces, such as a basement, garage, utility closet, or laundry room. . Step 2: Turn on your AC Disconnect . Step 3: Turn on your solar inverter (a.k.a. combiner box). . Step 4: Connecting the system to your home’s wifi. . [pdf]
Solar panels are a brilliant investment, offering a clean and sustainable way to power your home while reducing your electricity bills. However, there may be situations where you need to turn your solar system off, such as for maintenance, repairs, roof cleaning, or even during firefighting operations.
Connecting your solar system to the utility grid is a critical step in the activation process. Here’s what you need to do: Grid Connection Point: Identify where your solar system connects to the utility grid. This is usually located near your main electrical panel or utility meter.
Before you start connecting your solar panels to the mains, you will need to turn off the mains supply to your property. This is important to ensure that there is no risk of electric shock or damage to your equipment during the installation process. Once the mains supply has been turned off, you can begin connecting the inverter.
Simply do all the procedure in reverse. Start with turning on the DC side and then turning on the AC side. If it happens that your inverter does not come online again, you will need to call your solar installer. The steps that we have just explained refer to all PV systems.
Turn off the AC disconnect switch to disconnect the solar system from the utility grid. Breaker Switch: Locate the breaker switch dedicated to your solar system. Flip the breaker switch to the “off” position to cut off the power supply from the solar panels.
Locate the AC disconnect and breaker switch in your solar system and follow these steps: AC Disconnect: Find the AC disconnect near your utility meter or main electrical panel. Turn off the AC disconnect switch to disconnect the solar system from the utility grid. Breaker Switch: Locate the breaker switch dedicated to your solar system.
