We are professional at solar products development, research, production and launch. As one of the largest solar manufacturers and exporters of solar water heaters in China, we have rich technical force, well equipments and a number of high-precision mechanized production lines.
There exists one photo voltaic energy property application which is the rational place to begin, it almost usually may be the producing of domestic solar scorching h2o.  The particularly reasonable basis for this conclusion is that solar hot drinking water is normally the most financially rewarding and the easiest residential photo voltaic application that can be done. 

Normally, the expense of creating domestic sizzling h2o by traditional means constitutes between twenty-five percent and thirty-three percent of total residence power costs, and a solar scorching h2o system can save between two-thirds and over three-fourths of this energy cost.  

Of additional significance in starting with domestic hot water in converting a conventional power house to solar will be the increasing possibilities of handy do-it-yourself (DIY) solar drinking water items, either from scratch or buying easy to install goods available on the internet that are simple to implement and much cheaper than a full contractor installation.  Additionally, if total or partial solar drinking water residence heating is a likely prospect, this kind of system can be very economically and efficiently integrated. 

More often than not photo voltaic h2o systems have solar thermal panels, a liquid system to transfer the heat collected from the heat collector to storage or its location of usage; and a means for moving the fluid between the collector and storage or the location of usage.

An active system uses electric pumps and controllers to transfer the drinking water, while a passive system uses only thermosyphon combined with gravity to naturally transport the liquid as it truly is heated.  On the other hand, in some passive systems an integral collector-storage system (ICS or "batch system") may possibly be employed if circumstances are appropriate.  These systems have one or several black storage containers inside an insulated box with a glass side where cold drinking water is preheated in the solar collector tanks before moving into a fossil power drinking water heater. 

If a totally green active system is desired, there are also some excellent, cheap DIY photo voltaic power electricity kits which make it cost-effective to create sustainable onsite electricity with which to pump the liquid and to operate its electronic controllers.  Regardless of whether an active or passive system is employed, both virtually usually have a backup heat source available to heat the drinking water as required to help keep adequate temperatures. 

There are two underlying factors that flat-plate collectors are virtually constantly used in home solar applications: they achieve sufficiently high temperatures (less than 200 degrees Fahrenheit), and they are considerably less costly than the closest  collector alternative.  A flat-plate panel usually consists of (one) a dark metal or plastic plate to capture the photo voltaic heat, part two a clear glass or plastic cover which allows the solar heat to transmit to the absorber but minimizes heat loss, and (3) a plastic or metal insulated container with which to enclose the heat absorber.  The heat transfer liquid moves through pipes that are typically integrated with the heat absorber.  The typical installation affixes flat-plate photo voltaic collectors with a fixed orientation to the sun.  And, the best photo voltaic capture efficiency is obtained if the panel faces toward the sun and slopes at an angle to the horizon equal to the latitude plus approximately 10 degrees.

In this as in all alternative energy applications, there exists the double benefit of reducing fossil power expenses while reducing the associated environmental impacts of traditional power generation.
