Glossary of photovoltaics and solar energy

POwR Connect offers you its glossary on the key concepts of photovoltaics and solar energy.

P

Battery discharge depth

The depth of discharge (DOD) is a percentage that indicates the amount of energy consumed by a battery. It is calculated by dividing the amount of energy discharged by the total amount of energy stored in the battery.

PTF

The Technical and Financial Proposal (TFP) request, or where applicable, the Request for Proposal to Enter the Quarantine (PEFA), is the first step in the connection process. The processing time for the request can impact the project timeline before work can begin. It is therefore important to submit the connection request well in advance.

PTO

The Optical Termination Point (OTP) is the connection point between the fiber optic network and the customer's private network. It is installed inside the home and takes the form of a box with an optical port. The customer connects their ONT (or their modem if it has an internal ONT) to this optical port to access the fiber optic network.
