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.

A photovoltaic (PV) system needs unobstructed access to the sun's rays for most or all of the day. Shading on the system can significantly reduce energy output. Climate is not really a concern, because PV systems are relatively unaffected by severe weather. In fact, some PV modules actually work better in colder weather. Most PV modules are angled to catch the sun's rays, so any snow that collects on them usually melts quickly.
Not completely. Conventional electric or gas water heating systems are still necessary as a supplement to the solar water heating system, largely because the sun might not shine in a particular area for several days at a time. However, because solar water heaters are designed provide hot water directly to the tank of a gas or electric water heater, they reduce the need for the water heater to run on conventional fuels. And this in turn reduces your gas or electric bill. Depending on where you live, solar water heaters can provide up to 80% of your home's annual water-heating needs.
These are called Solar Panels or Solar Modules. They are the solid-state electrical devices that convert light into direct current electricity. Several modules wired together and placed on a roof or in a ground mounted system are called an “ARRAY”.

If the condition of the existing arresters is OK, then additional arresters may not be required. This will be ascertained during execution.
Solar photovoltaic installer responsibilities are to install module array interconnect wiring, implementing measures to disable arrays during installation; install required labels on solar system components and hardware; install photovoltaic (pv) systems in accordance with codes and standards using drawings, schematics, and instructions; apply weather sealing to array, building, or support mechanisms;
assemble solar modules, panels, or support structures, as specified; visually inspect and test photovoltaic (pv) modules or systems; activate photovoltaic (pv) systems to verify system functionality and conformity to performance expectations; check electrical installation for proper wiring, polarity, grounding, or integrity of terminations;
identify methods for laying out, orienting, and mounting modules or arrays to ensure efficient installation, electrical configuration, or system maintenance; identify and resolve any deficiencies in photovoltaic (pv) system installation or materials; test operating voltages to ensure operation within acceptable limits for power conditioning equipment, such as inverters and controllers; identify installation locations with proper orientation, area, solar access, or structural integrity for photovoltaic (pv) arrays; demonstrate system functionality and performance, including start-up, shut-down, normal operation, and emergency or bypass operations; perform routine photovoltaic (pv) system maintenance on modules, arrays, batteries, power conditioning equipment, safety systems, structural systems, weather sealing, or balance of systems equipment; identify electrical, environmental, and safety hazards associated with photovoltaic (pv) installations; measure and analyze system performance and operating parameters to assess operating condition of systems or equipment; determine connection interfaces for additional subpanels or for connecting photovoltaic (pv) systems with utility services or other power generation sources; program, adjust, or configure inverters and controls for desired set points and operating modes; determine appropriate sizes, ratings, and locations for all system overcurrent devices, disconnect devices, grounding equipment, and surge suppression equipment; examine designs to determine current requirements for all parts of the photovoltaic (pv) system electrical circuit;
compile or maintain records of system operation, performance, and maintenance; install active solar systems, including solar collectors, concentrators, pumps, or fans; determine photovoltaic (pv) system designs or configurations based on factors such as customer needs, expectations, and site conditions; determine materials, equipment, and installation sequences necessary to maximize installation efficiency; diagram layouts and locations for photovoltaic (pv) arrays and equipment, including existing building or site features; select mechanical designs, installation equipment, or installation plans that conform to environmental, architectural, structural, site, and code requirements.
We suggest you look for a PV installer or equipment provider in the telephone directory under "Solar Energy Equipment and Systems Dealers."
It is a good idea select a designer or installer of solar energy systems from the list in your local yellow pages by first asking for information from several of them about their experience with PV systems as well as how much their services and products cost. With a system designer, you can discuss power requirements or hot water needs for your building, sunlight availability, and other important factors, and determine the type of system that's needed to meet your needs. System designers and installers should be able to provide you with cost estimates and other pertinent information.
Today it is safe to say that there are no guarantees in any professional field of work. However, there are MANY reasons why Solar PV, as well as every other renewable energy field, will be growing for many years to come. Included in these reasons is the fact that there are several State and Federal “Green” or Renewable Energy” programs, Grants, Federal income Tax incentives and State Rebate programs that are scheduled to last for at least seven more years. Recent legislation, as well as pending legislation, exists in every one of our 50 United States governments that includes mandatory minimum thresholds that must be achieved for generating electrical power by use of “Renewable Energy” technologies.
