<p>Solar garden lights are installed in many public places or in private courtyards. So, what are the advantages and disadvantages of solar garden lights? </p><p><a href="alltopgroup.com" rel="noopener noreferrer" target="_blank"><strong>solar street light factory</strong></a> Introduce you to details</p><p><br></p><p>Advantages and disadvantages of solar garden lights</p><p><br></p><p>First, the advantages and disadvantages of solar garden lights</p><p><br></p><p>(A) the advantages of solar home courtyard lights</p><p><br></p><p>1. Green and environmental protection, high safety factor, low operating power, no potential safety hazards, can be recycled and used, and less environmental pollution.</p><p><br></p><p>2. The light from solar garden lights is soft and non-glare, without any light pollution, and does not generate other radiation.</p><p><br></p><p>3, solar garden lights have a long service life, semiconductor chips emit light, and the cumulative life can reach tens of thousands of hours, which is often higher than ordinary garden lights.</p><p><br></p><p>4, high use efficiency, effectively convert solar energy into light energy, compared with ordinary lamps, like thermal energy into light energy, the efficiency is several times higher.</p><p><br></p><p>(B) the disadvantages of solar home courtyard lights</p><p><br></p><p>1.Instability</p><p><br></p><p>In order to make solar energy a continuous and stable energy source, and eventually become an alternative energy source that can compete with conventional energy sources, the problem of energy storage must be well solved, that is, the solar radiant energy during sunny days is stored as much as possible for night or rain It is used by the sky, but energy storage is also one of the weaker links in the use of solar energy.</p><p><br></p><p>2.Low efficiency and high cost</p><p><br></p><p>Because of low efficiency and high cost, in general, the economy cannot compete with conventional energy. In a considerable period of time in the future, the further development of solar energy utilization is mainly restricted by economics.</p><p><br></p><p>How to install solar garden lights</p><p><br></p><p>1.Installation of battery board</p><p><br></p><p>Determine the tilt angle of the battery board according to the local latitude, weld the bracket with 40 * 40 galvanized angle steel, and the bracket is fixed on the side wall with expansion screws. Welded a steel bar with a diameter of 8MM to the bracket, with a length of 1-2 meters. The bracket was connected to the lightning protection belt on the roof with steel bars. Make a hole in the bracket and fix the battery board to the bracket with Φ8MM or Φ6MM stainless steel screws.</p><p><br></p><p>How to install solar garden light</p><p><br></p><p>2. Battery installation</p><p><br></p><p>A. First, check the battery packaging for damage, and then carefully unpack the battery one by one to check whether the battery is intact; and check the battery factory date.</p><p><br></p><p>B. The voltage of the installed battery is DC12V, 80AH, two of the same type and specifications are connected in series, providing 24V power supply.</p><p><br></p><p>C. Two storage batteries are put into the buried box (type 200). After the glue outlet of the buried box is glued, the protective tube (with a steel wire water supply pipe) is fastened step by step. The other end of the protective tube is led with silicone. Sealant seal to prevent water ingress.</p><p><br></p><p>D. Digging size of digging ground and digging box: Adjacent to the base of the courtyard lamp, it is 700MM deep, 600MM long and 550MM wide.</p><p><br></p><p>E. Buried box pool: Use single brick cement to enclose, put the buried box with the battery into the pool, lead out the conduit, and cover the cement board.</p><p><br></p><p>F. The batteries must be connected to each other with the correct polarity and the connections must be very firm.</p><p><br></p><p>G. After the battery pack is connected, connect the positive and negative poles of the battery pack to the positive and negative poles of the power controller respectively. Then apply a layer of vaseline to the joint.</p><p><br></p><p>Controller installation</p><p><br></p><p>A. The controller uses a dedicated solar power controller. When connecting the cable, first connect the battery terminal on the controller, then connect the photovoltaic panel wires, and finally connect the load terminal.</p><p><br></p><p>B. Be sure to pay attention to the battery, photovoltaic panel, load + and-poles cannot be reversed, and the photovoltaic cell panel and battery connection line must not be short-circuited. The controller is placed in the lamp post, fixed with bolts, and the door on the lamp post is locked.</p><p><br></p><p>4, lamp base</p><p><br></p><p>Concrete pouring, symbol: C20. Dimensions: 400mm * 400mm * 500mm, M16mm for embedded screw inspection, 450mm in length, and two Φ6mm stiffeners are added in the middle. (See Figure 3)</p><p><br></p><p>5.Laying of wires</p><p><br></p><p>A. All the connecting wires used are piped down from the top of the building, and can be led down from the threading well, or can be routed along the downpipe from the floor. The downstairs are used with a 25mm threaded pipe and the underground wiring is used with a 20mm thread. The joints of pipes and threading pipes are sealed with pipe joints, elbows and tees with glue.</p><p><br></p><p>B. Use special metal water supply hoses for special places to make them waterproof. Most of the connecting wires are BVR2 * 2.5mm2 sheathed wires.</p>
