A sun hour is a unit of measurement of the intensity of sunlight on the earth at a given time that can be used for generation of solar power, recognizing factors such as climate and weather. A full sun hour is measured as the intensity of sunlight at noon, whereas less than a full sun hour will result during the hours before and after noon.

Solar Panel: mininum 25 years of power generation capacity, with 10-years warranty LED Light: Mininum 50.000 hours life span, with 2-year all inclusive warranty - covers everything on the LED street lights, including lamp holder parts, power supply, radiatior, scaling gasket, LED modules & lens Battery: 5 to 7 years life span, with a 2-year warranty Controller inverter and all the electronic parts: Minimum 8 years by ordinary usage, with a 2- year warranty Pole solar panel bracket and all the metal parts: up to 10 years life span

Electrical energy is stored in the battery each day, and some of that energy is used to operate the light at night. Generally, we design your system so that the battery will operate the light for five nights without charging. This means that, even after a series of cloudy days, there will be plenty energy in the battery to power the light each night. Also, the solar panel will continue to charge the battery (although at a reduced rate) even when it is cloudy.

SunMaster’s solar controller uses a photocell and/or timer to control when the light will turn on, when the sun goes down, and to turn off when the sun comes up. The photocell detects when the sun comes down and when the sun comes up again. SunMaster can make the lamp last anywhere from 8-14 hours, and this varies on the customer’s needs. The solar controller utilizes an internal timer that is pre-set for a specific number of hours to determine when to switch the light off. If the solar controller is set to leave the light on until dawn, it determines when the sun rise (and when to switch the light off) by means of voltage readings from the solar panel array.

There is no regular maintenance required for a solar lighting system. However, it is helpful to keep the solar panels clean, especially in a dusty climate.

Our suggestion for using 24V battery bank for solar LED system is based on our research which we conducted earlier before launching our Solar LED system. What we did in our research was that we actually tested both the systems 12V battery bank and as well as 24V battery bank.

In order to customize your solar light project the first thing we need to focus on is the location for installing the solar power lighting system and the perfect location where you want to install your solar light project, because different locations and surface have different levels of sunlight which can have an impact on the outcome of the solar light project.

Batteries are shipped 85% charged. The batteries will be at 100% charged within two weeks of proper operation.

Gel battery also known as VRLA (valve regulated lead-acid) batteries or gel cells, contains acid that has been gelled by the addition of silica gel, turning the acid into a solid mass that looks like gooey Jell-O. They contain less acid than a regular battery. Gel batteries are commonly used in wheelchairs, golf carts and marine applications. There are several advantages to using gel batteries.

Installing a solar or wind powered LED street light isn’t any sort of rocket science, in fact anyone willing to install by himself can do it easily.
