SOLAR GRID TIE INVERTERS(Built in MPPT)
As electricity keeps getting expensive you are likely to recover the entire cost of solar system in just 4years as you are not paying much to the electricity company.
Grid Tie Solar electric systems generate electricity silently and without any moving parts. Sunlight falls on the solar Panels and generates DC electricity. That DC electricity is converted into household 230V AC electricity by the inverter. The AC electricity is fed into your electric meter and circuit breaker panel. The electricity either goes to your appliances and lights, or to the grid, same to each. This happens silently and automatically every day. When PV solar panels are generating DC and inverter is feeding to the main supply after converting it into AC, you are saving money because you are taking absolutely NOTHING from the grid. You can literally see your electricity meter stop when there is sun. Presently we are using SMA, luminous, su.kam etc..where MPPT charger is built in. It is a best income source If space is available
SOLAR OFF GRID INVERTER (MPPT Technology)
This is just one of the Solar Power Generating Systems available with true sharing between Battery and solar most efficiently. It has a DSP based MPPT Charge Controller. When the Solar is available, the grid charger will forcefully switch off and the load remains on grid. When the battery reaches the full charge level it forcefully switched off the grid and the load handled by the battery and the Solar. When the battery discharges to a preset level (adjustable) the load changes from battery to mains and the solar power is used to charge the battery. This process will repeat and saves the Grid Power. In addition to this an extra switch on Inverter for shutdown the grid charger manually. Thus the system never activates the grid charger at any condition. When Mains is on, Solar and Mains do not charge each other like in other systems but the charging is intelligently done with Solar Power.
SOLAR OFF GRID INVERTER (PWM Technology)
This is just one of its kind Solar Hybrid UPS. It has a micro controller based PWM Charge Controller which can handle up to 2kw system. When the Solar is available the battery charging is done only with Solar. It comes with a switch on the rear side to shutdown the mains charger permanently. Grid power will not be used for charging the Battery. Thus we can save the electricity bill by avoiding the battery charging through mains.
SOLAR MPPT CHARGERS
An MPPT, or maximum power point tracker is an electronic DC to DC converter that optimizes the match between the solar array (PV panels), and the battery bank. To put it simply, they convert a higher voltage DC output from solar panels (and a few wind generators) down to the lower voltage needed to charge batteries.
Maximum Power Point Tracking is electronic tracking - usually digital. The charge controller looks at the output of the panels, and compares it to the battery voltage. It then figures out what is the best power that the panel can put out to charge the battery. It takes this and converts it to best voltage to get maximum AMPS into the battery.. Most modern MPPT's are around 93-97% efficient in the conversion. You typically get a 20 to 45% increase in efficiency by using MPPT. Actual gain can vary widely depending weather, temperature, battery state of charge, and other factors.
SOLAR PWM CHARGERS
PWM solar chargers use technology similar to other modern high quality battery chargers. When a battery voltage reaches the regulation set point, the PWM algorithm slowly reduces the charging current to avoid heating and gassing of the battery. They have been used for years in Solar systems, and are well established. These controllers are inexpensive and durable.The Solar input nominal voltage must match the battery bank nominal voltage if you’re going to use PWM. Can’t be used on higher voltage grid connect modules. It is not tracking the solar power level and hence efficiency is less compared to MPPT technology. It is advisable up to 2 KV systems
SOLAR WATER HEATER
We are blessed with Solar Energy in abundance at no cost. The solar radiation incident on the surface of the earth can be conveniently utilized for the benefit of human society. One of the popular devices that harness the solar energy is SOLAR WATER HEATING SYSTEM.
A solar water heater consists of a collector to collect solar energy and an insulated storage tank to store hot water. The solar energy incident on the absorber panel coated with selected coating transfers the heat to the riser pipes underneath the absorber panel. The water passing through the risers get heated up and are delivered to the storage tank. The re-circulation of the same water through absorber panel in the collector raises the temperature to 80 C (Maximum) in a good sunny day. The total system with solar collector, storage tank and pipelines is called solar hot water system. Broadly, the solar water heating systems are of two categories. They are: Pressurized and Non-Pressurized.
PRESSURIZED SOLAR WATER HEATERS
In the Pressurized system, heat exchangers are installed to protect the system from hard water and Pressure Pumps. The forced circulation systems employ Pressure pumps to circulate the water through collectors and storage tanks. The choice of system depends on heat requirement, weather conditions, heat transfer fluid quality, space availability, annual solar radiation, etc. The SHW systems are economical, pollution free and easy for operation in warm countries like ours. Pressurized systems are generally preferred in industries or large establishments.
NON-PRESSURIZED SOLAR WATER HEATERS
In the Non-Pressurized system, the water in the system is open to the atmosphere at one point or other. These systems are simple and relatively inexpensive. They are suitable for domestic and small institutional systems.
FLAT PLATE COLLECTORS(FPC)
In the Flat Plate Collector (FPC) based Solar Water Heaters the solar radiation is absorbed by Flat Plate Collectors which consist of an insulated outer metallic box covered on the top with 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.
EVACUATED TUBE COLLECTORS (ETC)
In the Evacuated Tube Collector (ETC) based Solar Water Heaters, Evacuated Tube Collector is made of double layer borosilicate glass tubes evacuated for providing insulation. The outer wall of the inner tube is coated with selective absorbing material. This helps absorption of solar radiation and transfers the heat to the water which flows through the inner tube.
ETC based systems are cheaper than FPC based system. They perform better in colder regions and avoid freezing problem during sub-zero temperature. FPC based systems also perform well with anti-freeze solution at subzero temperature but their cost increases. In other regions, both perform equally well. Systems working on thermosyphon principle are simple and relatively inexpensive. They are suitable for domestic and small institutional applications, provided water quality is good and it doesn't have large chlorine contents
SOLAR PANELS
Solar Panels, also known as Solar Photovoltaic (PV), capture the sun's energy using photovoltaic cells. These cells don't need direct sunlight to work – they can still generate some electricity on a cloudy day. The cells convert the sunlight into electricity, which can be used to run household appliances and lighting.
PV cells are made from layers of semi-conducting material, usually silicon. When light shines on the cell it creates an electric field across the layers. The stronger the sunshine, the more electricity is produced. Groups of cells are mounted together in panels or modules that can either be mounted on your roof or on the ground.
The power of a PV cell is measured in Watts peak {Wp}. That's the rate at which it generates energy at peak performance in full sunlight during the summer. PV cells come in a variety of shapes and sizes.
MONO CRYSTALLINE SOLAR PANELS
Mono Crystalline Solar Panels have the highest efficiency rates since they are made out of the highest-grade silicon. The efficiency rates of mono crystalline solar panels are typically 15-20%. They can perform better than similarly rated polycrystalline solar panels at low-light conditions.
Mono Crystalline Silicon Solar Panels are space-efficient. Since these solar panels yield the highest power outputs, they also require the least amount of space compared to poly crystalline. Mono Crystalline solar panels produce up to four times the amount of electricity as thin-film solar panels.
Mono Crystalline Solar Panels live the longest. Most solar panel manufacturers put a 25-year warranty on their Mono Crystalline solar panels.
POLY CRYSTALLINE SOLAR PANELS
In the Poly Crystalline Solar panels the cells are cut from an ingot of melted and recrystallised silicon. In the manufacturing process, molten silicon is cast into ingots of polycrystalline silicon, then saw-cut into very thin wafers and assembled into complete cells. Polycrystalline cells (also known as multicrystalline) are cheaper to produce than monocrystalline ones, due to the simpler manufacturing process. However, they tend to be slightly less efficient for the same size cell.
Polycrystalline Panels typically offer a lower cost per watt of power produced. These cells have a better temperature de-rating co-efficient compared to monocrystalline, meaning they produce more power in hotter weather, which usually more than offsets their slightly lower cell efficiency. Polycrystalline cells are slightly less efficient than monocrystalline cells, so they need more roof space to produce the same output capacity.
CONNECTORS
MC4 connectors are single-contact electrical connectors commonly used for connecting solar panels. MC4s allow strings of panels to be easily constructed by pushing the connectors from adjacent panels together by hand, but require a tool to disconnect them to ensure they do not accidentally disconnect when the cables are pulled. The MC4 and compatible products are universal in the solar market today, equipping almost all solar panels produced since about 2011
SOLAR LIGHTS
A solar lamp also known as solar light or solar lantern, is a lighting system composed of high efficient LEDlamp, solar panels, battery, charge controller and there may also be an inverter. The lamp operates on electricity from batteries, charged through the use of solar photovoltaic panel. solar lamps reduce health risk as kerosene lamps have a bad impact on human health.
SOLAR AIR CONDITIONERS
Solar air conditioning refers to any air conditioning system that uses solar power. This can be done through passive solar, solar thermal energy conversion and photovoltaic conversion (sunlight to electricity). Solar collector collects heat from the sun and heats the water inside the tank, high temperature high pressure steam (Freon) comes from the compressor, the high temperature high pressure steam will flow to the copper coil of the Solar Collector for heat exchange. The Solar Collector makes the high temperature high pressure steam ( Freon) into the higher temperature and higher pressure. In short, the Solar Collector helps the compressor to make the temperature and pressure higher. This is why, the Solar Air Conditioner can save electricity and increase the energy efficiency when cooling.
Solar PV AC: It's a 100% Solar Photovoltaic Air Conditioner, no grid power required, zero electricity bill. Thus Solar Thermal Air conditioner can save you upto 60% electric bill, but as SOLAR PHOTOVOLTAIC (PV) SYSTEM AIR CONDITIONER runs fully from SOLAR ENERGY, it saves you full Electric bill. Thus FREE ENERGY at least for 25 years
PANEL FRAMES
Photovoltaic mounting systems (also called solar module racking) are used to fix solar panels on surfaces like roofs, building facades, or the ground. These mounting systems generally enable retrofitting of solar panels on roofs or as part of the structure of the building. A solar cell performs the best when its surface is perpendicular to the sun's rays, which change continuously over the course of the day and season. It is a common practice to tilt a fixed PV module (without solar tracker) at the same angle as the latitude of array's location to maximize the annual energy yield of module.
ENERGY METERS
An energy meter keeps track of the all the power your solar system produces. Any solar energy that you do not use simultaneous with production will go back into the electrical grid through the meter. The energy production can be monitor by using the system. The perfomence of solar system installed can be analysed by installing energy meters. Net energy metering, or "NEM", is a special billing arrangement that provides credit to customers with solar PV systems for the full retail value of the electricity their system generates. Under NEM, the customer's electric meter keeps track of how much electricity is consumed by the customer, and how much excess electricity is generated by the system and sent back into the electric utility grid. Over a 12-month period, the customer has to pay only for the net amount of electricity used from the utility over-and-above the amount of electricity generated by their solar system
BATTERY
The integral part of a solar UPS is the battery bank. The battery acts as a back-up power source that supports the UPS system. The most popular battery system being used with UPS is the Lead acid battery system. Batteries in solar applications have to meet the demands of unstable grid energy, heavy cycling (charging and discharging) and irregular full recharging. There’s a variety of battery types fitted for these unique requirements. Considerations for choosing a battery include cost, cycle life and installation and maintenance. Battery sizing is essential but often overlooked by users and installers. Batteries in PV systems are routinely undersized due to cost or because the system loads were underestimated. It’s important to know the customer’s power needs and correctly plan. No need of batteries in the Grid tie system as they are connected to electricity grid.
For decades, lead-acid battery technology has been the mainstay of battery-based renewable energy systems, providing reliable storage and ample energy capacity. The most common battery used—flooded lead-acid (FLA)—requires regular watering to maintain electrolyte levels and venting to avoid the buildup of hydrogen and sulfuric gases. Additionally, FLAs are large and heavy, making battery replacement a challenging task for some systems.Lithium-Ion batteries allow to equip solar “off-grid” power stations, replacing the legacy banks of lead-acid batteries. Its lifetime (number of cycles) is well above the lead-acid batteries. Footprint and weights 2-3 times lower than lead-acid. No maintenance required. Compatibility with installed equipment (charge controllers, AC converters, etc.) by using advanced BMS. Green solutions (non-toxic chemistries, recyclable batteries)
