What is series resistance of a solar cell?

Series resistance does not affect the solar cell at open-circuit voltage since the overall current flow through the solar cell, and therefore through the series resistance is zero. However, near the open-circuit voltage, the IV curve is strongly effected by the series resistance.
A.

What is index fill factor?

Fill factor is the value that determines the percentage of space on each leaf-level page to be filled with data. In an SQL Server, the smallest unit is a page, which is made of Page with size 8K. Every page can store one or more rows based on the size of the row.
  • What is the use of index in SQL Server?

    An index is an on-disk structure associated with a table or view that speeds retrieval of rows from the table or view. These keys are stored in a structure (B-tree) that enables SQL Server to find the row or rows associated with the key values quickly and efficiently.
  • Why do we need index in SQL?

    An index is used to speed up the performance of queries. It does this by reducing the number of database data pages that have to be visited/scanned. In SQL Server, a clustered index determines the physical order of data in a table.
  • Is SQL Server is free?

    Microsoft SQL Server Express is a version of Microsoft's SQL Server relational database management system that is free to download, distribute and use. It comprises a database specifically targeted for embedded and smaller-scale applications.
B.

How can you find the efficiency of a solar cell?

Solar cell efficiency refers to the portion of energy in the form of sunlight that can be converted via photovoltaics into electricity. The efficiency of the solar cells used in a photovoltaic system, in combination with latitude and climate, determines the annual energy output of the system.
  • What is the efficiency of the solar cells?

    DS1's solar panels convert 22% of their available energy into electrical power. This may not sound very good, but it is much better than most solar panels. Most solar panels on people's houses, for example, are fairly inefficient. Less than 14% of the energy that reaches them will be converted to electricity.
  • Do solar panels lose efficiency over time?

    What Is the Lifespan of a Solar Panel? Photovoltaic (PV) modules typically come with 20 year warranties that guarantee that the panels will produce at least 80% of the rated power after 20 years of use. The general rule of thumb is that panels will degrade by about 1% each year.
  • What is the difference between mono and poly solar panels?

    Because of lower silicon purity, polycrystalline solar panels are not quite as efficient as monocrystalline solar panels. Lower space-efficiency. You generally need to cover a larger surface to output the same electrical power as you would with a solar panel made of monocrystalline silicon.
