ON-GRID SOLAR SYSTEM
An on-grid solar system is designed to switch seamlessly between the residential solar system and the grid. It connects your home to both, utility grid and solar system and hence, you can get electricity from either of the two sources.
Also known as the grid-tie solar system, this type requires only two main components- solar panels and solar inverters. Storage devices like the solar battery are not a part of this system therefore, they can’t provide you power backup. In an on-grid solar system, the solar panel generates the electricity and the solar inverter converts it into AC electricity. Thereafter, the electricity is used subsequently by your appliances.
In case, the system is generating more electricity than your consumption then excess electricity will be automatically injected into the utility grid. This system allows you to export unconsumed or extra electricity to the grid through net metering.
OFF-GRID SOLAR SYSTEM
Specially designed for remote residences, an Off-grid solar system is a complete power bank that is independent of the utility grid for functioning. This type of solar system is also known as a battery-based system and stand-alone system. In this solar system, you will get to see a specialty that you didn’t get in the earlier system.
This system comes with a solar battery and does provide power backups during emergencies or outages. Other functions and components will remain the same as in the on-grid solar system. But instead of exporting extra/unconsumed electricity to the grid, you can store it in solar batteries. This stored electricity can further be used to power your electrical or solar appliances
The off-grid solar system is a battery based, independent solar system that does not need a utility grid to illuminate your places. It is a complete solar setup with solar panels, solar battery, and solar inverter, and is ideal to lighten a home even in a far off location. This solar system is more prominent as it comes with a power backup.
Like every other solar system, an off-grid solar system uses a solar panel to absorb sunlight and convert it into electricity. In the day time solar will run the connected load and balance energy will be stored in the solar battery. So in the daytime, the solar system runs home appliances generating electricity using sunlight and stores the extra energy into the battery bank. And at night when there is no sunlight, the appliances draw energy from the battery to keep running. Hence, the system works day and night.
SOLAR STREET LIGHTS
A battery based solar street light is a standalone system, which will store electricity generated by solar panel in solar battery. Solar LED Street light is powered by photo-voltaic panel, generally mounted on the light structure or integrated in the pole itself.
There is also another type of street light called integrated solar street light. In both type of street lights, the photo-voltaic panel charge solar battery during day time, which powers LED lamp during night. Street light comes with dusk to dawn sensors, which automatically switch-on the light in evening and off in the morning
WHY SOLAR LIGHTS?
The effect of global warming was very recently felt in the Earthquake & the Tsunami in Japan. As leaders in outdoor lighting we are driven by the challenge of providing a environment friendly technology and focus on a more sustainable solution of renewable energy to our society.
Solar LED Street light address the situation to the best. To begin with, LED light use far less power than their old-fashioned counterparts and last for a considerable longer time, thus being more economical and environment friendly.
In addition, the quality of the light actually produced by solar LED light is far superior than conventional lights. Conventional lights still mostly produce that yellow orange light, which does not allow very high definition visibility.
Employing LED technology, on the other hand, can create a much more powerful, crisper white light of far higher quality, significantly improving visibility and Color rendition.
ETC SOLAR WATER HEATER
In ETC Solar Water Heater, the collector is designed to provide insulation using double layer borosilicate glass tubes. Each evacuated tube consists of two glass tubes having vacuum in between which is an excellent insulator. The outer wall of the inner tube is made to absorb maximum solar radiation. And that is why the wall is coated with demanding absorbing material.
Evacuated Tube Collector (ETC) acts as an absorber in the solar water heater. The incident solar radiation falling on the tube passes through the outer transparent tube and strikes the outer of inner tube. It absorbs heat energy and then passes to the cold water flowing in the tube. Hence, the heat gets transferred to the cold water resulting in heating the water.
An evacuated tube technology based solar water heating system is most energy efficient and cost effective that are best suitable for home use.
FPC SOLAR WATER HEATER
In an FPC solar water heater, the solar radiation is absorbed by Flat Plate Collectors (FPC) which consist of an insulated outer metallic box covered on the top with a glass sheet. Inside there are blackened metallic absorber (selectively coated) sheets with built in channels or riser tubes to carry water. The absorber absorbs the solar radiation and transfers the heat to the flowing water.
A flat plate technology based solar water heater is more energy efficient. Also it has a long life. Hence, such a heater is most suitable for home use.
SOLAR SUBMERSIBLE PUMP
Solar submersible pumps are used where water has to be lifted from deeper underground. If put in simple words, this pump is used to lift water from a depth of more than 15 meters. To lift the water, simply put the pump inside the water and switch it on, the rest of the work will be done by the solar itself. Solar submersible water pumps are the most preferable pumps in India as the water depth is very high in maximum areas.
SOLAR SURFACE PUMP
Surface pumps are relatively small but powerful water pumps. They are used to lift shallow water. If the depth of water is 15 meters or less than 15 meters then a solar surface pump is recommended. It can easily lift the water to the ground or above the ground level. You will find this type of pump pulling water from streams, storage tanks, shallow wells, and ponds at many places.
There are two technologies to power your solar surface water pump (AC & DC) and solar submersible water pump (AC & DC). A brief description of these technologies is mentioned below.
ON-GRID SOLAR PUMP
In an on-grid solar system, your water pump will be powered by a solar panel. In case the solar panel is generating more power than the water pump’s consumption, then the excess power will automatically be exported to the grid via net metering and the government will adjust it in your next electricity bill.
HYBRID SOLAR PUMP
In a hybrid solar pump, there are three power options to run the solar pump. First is solar power, second is the grid electricity and the third is a solar battery. In day time your water pump is powered by solar electricity, at night it is powered by the grid and when both (solar power and grid) are not available then it will be powered by a battery.
