The first component (whether light or heavy is appropriate)
Good wooden doors should not be too light. Compared with the wooden doors of the same specifications and the same layer of wood, the wooden doors with too small weight are hardly said to be high-quality wooden doors. The reason why the weight is too light is that the material of the selected core material is relatively soft (such as poplar), and the pipes and pores in the wood are relatively large. Or the core material inside is too small, making the wooden door not strong enough. The strength and impact resistance of such wooden doors are relatively poor, and the sound insulation effect is also poor.
Second look (painted surface and veneer)
The high-quality wooden door paint is full and smooth, rich and natural, and the transparency of the paint film is good. The texture of the surface material is clear and vivid, and the physical properties of the appearance are unobstructed. Inferior wood door paint film is dry, exposed paint, bubbling, pinholes, corrugations, particles, etc., the transparency of the paint film is poor, the surface texture is ambiguous, and the appearance of wood is difficult to distinguish. The reason why inferior wooden doors are so, is that the quality of the paint used by the manufacturer is poor, the process and equipment are not good; on the other hand, the choice of veneer is too much, so the transparency of the coating is deliberately reduced to cover the death of the surface. Sections, holes, decay, discoloration, cracks, indentations, etc.
Third look at the veneer or solid wood splicing
The veneer or solid wood splicing of high-quality wooden doors is relatively fine, and there is no visible bond. Inferior wooden doors, veneer or solid wood splicing is obvious, even cracking and dislocation.
Fourth, look at the flatness of the wooden door
High-quality wooden doors are strict in material selection, process control and factory inspection, and the finished wooden door surface is flat and straight. The shape is perfect after installation. The inferior wooden doors have low requirements on materials, processes and inspections, and the warpage of the finished wooden doors is large. It is obvious that the wooden doors and the door frames cannot be neatly arranged after installation.
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
