What is solar specific yield?
Posted by First Green Consulting. The “specific yield” (kWh/kWp) is the total annual energy generated per kWp installed. It is often used to help determine the financial value of an array and compare operating results from different technologies and systems.
How do you calculate the specific yield of a solar panel?
However, due to different solar module design and efficiencies, it is easier to evaluate the performance (and hence their capability) of various solar modules by determining its specific energy yield (kWh/kWp) (i.e. by dividing the absolute yield (kWh) to its power output PSTC (kWp)).
What is specific photovoltaic power output?
The PV power output (PVOUT), defined as the specific yield, is used to illustrate this potential. PVOUT represents the amount of power generated per unit of the installed PV capacity over the long-term, and it is measured in kilowatthours per installed kilowatt-peak of the system capacity (kWh/kWp).
What is yield energy?
The net energy yield refers to the amount of energy that is gained from harvesting an energy source. This yield is the total amount of energy gained from harvesting the source after deducting the amount of energy that was spent to harvest it.
What is energy yield ratio?
The yield ratio is defined as the energy fed back by the material to the energy received from the environment. The primary fuel only can accelerate growth but their supply is limited. [b] Secondary energy sources.
What is specific yield?
Specific yield is defined as the ratio of (1) the volume of water that a srturated rock or soil will yield by gravity to (2) the total volume of the rock or soil. Specific yield is usually expressed as a percentage.
How do you find the specific yield?
The specific yield is the volume of water pumped during the test divided by the gross volume of dewatered material within the cone of depression.
What is specific annual yield?
Specific yield (or simply “yield”) refers to how much energy (kWh) is produced for every kWp of module capacity over the course of a typical or actual year.
What is the energy yield ratio?
What is the net energy yield of solar energy?
5.8
Net-Energy Ratio
| Energy Source | Net-energy Ratio |
|---|---|
| Solar Energy | 5.8 |
| Natural Gas | 4.9 |
| Petroleum | 4.5 |
| Coal-fired Electricity | 2.5-5.1 |
What is annual energy yield?
The annual energy yield is readily understood as the total number of kilowatt hours actually produced by a wind turbine installation in a year.
What does a high specific yield mean?
Specific yield is part of the total porosity of a porous rock or sediment. The total porosity (total pore space) of a rock or sediment formation is much larger than the specific yield. Fine-grained sediments have the largest specific surface area, the highest specific retention, and the lowest specific yield.
