Solar Panel Technician Interview Preparation Guide

Separate chemical earthing up to 5ft as per standard design norms will be constructed by us as part of our execution scope.

I have the ability to tell when something is wrong or is likely to go wrong. It does not involve solving the problem, only recognizing there is a problem, imagine how something will look after it is moved around or when its parts are moved or rearranged, see details at close range (within a few feet of the observer), arrange things or actions in a certain order or pattern according to a specific rule or set of rules (e.g., patterns of numbers, letters, words, pictures, mathematical operations), apply general rules to specific problems to produce answers that make sense.

The size of solar system you need depends on several factors such as how much electricity or hot water or space heat you use, how, the size of your roof, and how much you're willing to invest. Also, do you want the system to supply your complete energy usage or to supplant a portion of your higher cost energy usage? You can contact a system designer/installer to determine what type of system would suit your needs.

In a recent Newsweek Web Exclusive article, (August 25, 2009), Matthew Phillips states that “Despite the bad economy, or maybe even because of it, the rooftop-solar industry is booming. Americans are increasingly becoming intrigued by the idea of turning their roofs into mini power plants and cutting their electric bills. In 2008, 33,500 rooftop solar systems were installed in the United States. This is a 63 percent increase over the amount of capacity installed in 2007. In California, the solar capital of the country, the increase was 95 percent.

unit of electric current (refers to flow of current); one ampere corresponds to a certain number of electrons passing a fixed point each second.

technology and research that relates to the application of solar cells for energy by converting radiant energy directly to electricity.

single silicon crystal; monocrystalline panels are made from one large, single silicon crystal making it rated the most efficient solar technology available.

solar cells produced from processed liquid silicon; when solidified, multiple silicon crystals are formed. Less efficient than monocrystalline cells.

Solar PV power plants are specified in KWp, not KWH. KWp means Kilowatt Peak. Please read this link for more information.

So a quote for 100 KWp does not guarantee that you will get 100 units of electricity per hour. Typically a 100 KWp plant will produce 1, 50,000 to 1, 80,000 Units of electricity per year. The actual generation every month, week, day and hour will depend on various factors and location.

Yes, the design takes care of all these conditions, as relevant to the city / location of installation. The structural engineering and drawings on roof top installation will be submitted for customer’s approval. This can be further validated by the customer with the help of a suitable architect / expert.
