| 如何选择太阳能灯控制器？ |
太阳能专家教授告诉我们，小小的太阳能路灯，能为社会节约多少能源呢？按照有关机构及专家测定，每盏太阳能路灯每年可节约438度电和155千克标煤，减排二氧化碳106千克。我们选择的控制器是防水的，带LED，横流的，具有防过充过放的保护蓄电池的功能。可以分时段控制。 不容易腐蚀和绣掉。控制器是太阳能的心脏。 选产品一定要看质量。太阳能控制器应用于太阳能光伏系统中，协调太阳能电池板、蓄电池、负载的工作，是光伏系统中非常重要的组件。使整个太阳能光伏系统高效，安全的运作。太阳能路灯控制器主要用于家庭、商业区、工厂、交通、牧区、通信以等太阳能供电系统。
作为太阳能路灯控制器应该具备以下基本功能:
1. 过载保护；
2. 短路保护；
3.反向放电保护；
4.极性反接保护；
5. 雷电保护;
6. 欠压保护;
7.过充保护；
8. 负载开机恢复设置。
太阳能路灯控制器选择时要考虑如下功能：
1.LED灯恒电流输出；
2.输出时间段的控制；
3.有没有温度补偿；
4.有没有线损补偿；
5.充电模式是什么样的。
另外根据太阳能路灯的使用环境，有些地区比较潮湿，就要考虑控制器的锈蚀问题，控制器不防水时间长了，插接扣容易腐蚀生锈造成短路，影响系统的正常使用，所以建议最好使用防水型控制器。

| 太阳能路灯在正常工作后容易出现哪些问题？ |
太阳能路灯是一个集成的发电和用电系统，它的构造很复杂，零配件繁多，太阳能路灯的零部件主要有太阳能电池板，蓄电池、光源等。再加上太阳能路灯是在室外，所以容易出现各种问题。太阳能路灯是一个集成的发电和用电系统，它的构造很复杂，零配件繁多，太阳能路灯的零部件主要有太阳能电池板，蓄电池、光源等。再加上太阳能路灯是在室外，所以容易出现各种问题，以下将详细介绍太阳能路灯容易出现问题的四大地方，以防出现问题是我们能够很好的解决：
第一、太阳能路灯灯光闪烁，亮度不稳定，出现这个原因，首先更换灯具，如果更换了灯具还是那么闪烁的话，就可以排除是灯具的问题，这个时候要检查线路了，很有可能是线路的接口接触不良导致.
第二、太阳能路灯阴雨天只能坚持一到两天，引起这个原因有主要有两点原因。太阳能蓄电池充电不满，太阳能蓄电池充电不满就是太阳能充电的原因，首先观察一下最近天气情况如何，是否能保证每天充电5--7小时左右，如果充电只达2--3小时这样的情况是正常的请放心使用。另外检查电池是否老化，正常工作情况下电池的寿命的是4--5年。
第三、太阳能路灯停止工作，当太阳能路灯停止工作，首先检查控制器是不是坏了，出现这种情况很大原因就是太阳能控制器坏了，及时进行维修。以上是太阳能路灯容易常出现问题的三点原因，太阳能路灯安装好了以后要经常的进行检查，排除故障21世纪的汽车尾气排放，工业有毒气体的排放，水资源土地资源的污染等变的十分的严重。太阳能被称为新能源清洁能源，能否解决环境污染的问题呢？
第四、安装时尽量不要遮挡太阳能板，以达到光照效果。定期进行维护与卫生清理，特别在灰尘比较大的道路要一年进行一次清理。灰尘比较小的道路与小区、公园、三年进行一次清理工作，以免影响充电效果。

| VANUATU solar power system |
|
We can learn from the photo that government representative in VANUATU is showing how the solar power system （ZD-SH500 produced by JIAXING ZHONGDIAN NEW ENERGY CO LTE）works.
This magical machine raised those local residents’ eyebrows when it generates electricity from solar energy instantly.
This successful show is forming the foundation for further cooperation between us.
The performance of our solar power system was affirmed and praised from VANUATU government, and they had placed an order with 100 solar power systems already. |

| What will happen in cloudy days? |
| Electricity is stored in the battery each day, and some of that energy is used to power the light at night. Usually, we ensure the solar lighting will work for 3 nights without charging. This means that, even after raining day, there still have enough energy in the battery to power the light at night. Surely, we can design it with shorten or extend batteries backup days according to the local circumstance. |

| Can I use existing poles? |
Solar powered light fixtures can be fixed to an existing light pole provided:
The existing light pole should in good operating condition;
The existing cable should be replaced;
The existing light pole should strong enough to support the additional weight and resist wind. |

| How does solar lighting work? |
| The sun's energy is clean, endless and free. There is enough energy from the sun to power the entire earth forever. When the sun radiate on crystals panels made from silicon – solar panel, it turns into an electrical current. During daytime the solar panels convert solar energy to electricity. The solar panels charge the lead acid batteries and gel batterries. After dust, the controller order the batteries discharge electricity to run the light automatically. Until dawn, the controller order the batteries stop discharging automatically and start a new circle.

| Do I need to clean the panels periodically? |
| Most of our customers do not clean their panels. In most areas of the country, there is sufficient rain to clean the panels. However, if you are in a dusty area (very near a busy dirt road, very urban area, etc.) you may see a performance gain from cleaning the panels monthly. If necessary, a hose stream is usually sufficient for cleaning. Do not walk on or over the panels to clean them. Do not use metal, hard, or abrasive methods for cleaning. Do not spray water on the panels when they are very hot. |

| What will happen if the panels under shade? |
| PV panels should be installed in areas where they get significant shade-free sun every day. Even small amounts of shade can significantly reduce the output. Our designs and installations also seek to minimize the impact of any shade issues through selection of the proper equipment and good engineering. |

| What will happen if the panels are covered by snow? |
| Solar electric panels need sunshine to generate power. While some sun does make it through several inches of snow, little electricity is generated when the panels are covered with anything. Most power is made during clear sunny days. Our estimates take that into account. |
| Back to top |
| How much power does the system output per day? |
| In the same city, the bigger the solar panel, the more the output power. With the same solar panel, the stronger the solar radiation the more the output power. We will know you the estimate output power for your project. |

| Should panels face to the sun? |
| Face to the sun, and choose the best angel to reveice solar radiation as much as possible. It is usually more effective and attractive. |
