In Europe, there are three agencies that can represent standards on behalf of the European Commission: c en (European Committee for Standardization), c en elec (European Commission for Electric Engineering), etsi (European Telecommunications Standards Institute) Work with the other two agencies to develop the necessary standards. In the European Machinery Directive, which contains hundreds of standards, Eurostat divides them into three distinct hierarchies for better management and compilation of these standards: Category a (Basic), Category b (Category Standard) and c standard (product standards). The standard of type a is the basic standard that all machines must meet. Under the a standard is a reference to a standard developed class b standard for the provisions of various types of machines, b standard is not for a specific type of machine, but the common category of machines Made a provision. On the basis of the b standard, a large number of c standards have been developed, each of which has a detailed specification for a specific machine. In addition, the b standard is divided into b1 standard and b2 standard. The b1 standard specifies the parameters related to safety protection such as safety spacing, surface temperature, noise, etc .; b2 standard specifies the specific requirements of the safety protection device, Such as hands button, safety door switch, safety carpets and so on. All of these European standards (en standards) are unmodified in their national standards (eg the d in standard and the vde code in Germany). These common standards in various European countries can guide manufacturers how to get their products ce mark, and if manufacturers meet the requirements of these standards can be considered to meet the requirements of the European Directive. The following is a part of the European standards that have been officially implemented and pre-implemented.

Ground mounting is the easiest installation. We often recommend doing this until you decide how you want to do your final mounting. As long as the panels are in the sun, your pump will pump. You can use anything you`d like to prop the solar panels up or use the RPS Adjustable mounts to attach to a wood or concrete footing. Be sure to ground the frame of the panels with a grounding rod. We do not recommend this if you have cattle or lots of animals around that could knock panels over.
Advantages
1. Suited for soft or extremely rocky soil-types
2. High level of pre-assembly for fast field installation
3. No heavy machinery necessary
